[047] Hereinafter, the present invention will be described in more detail with respect to the attached drawings.
[048] Figures 1a to 1c are views illustrating a predetermined product for which a transparent display device in accordance with the present invention is provided. Figure 1a illustrates a predetermined product for which the transparent display device is provided on a front surface, Figure 1b illustrates a predetermined product from which the transparent display device is decoupled, and Figure 1C illustrates an open predetermined product by the rotating movement of the transparent display device.
[049] As shown in Figures 1a to 1c, the transparent display device 20 in accordance with the present invention may be provided to a front surface portion of the predetermined product 10 to serve as a door unit of the predetermined product 10.
[050] In that case, the predetermined product 10 may be a refrigeration storage device, such as a refrigerator. The predetermined product 10 can be a storage device that can hold multiple items or it can be a digital signage without limitation to the refrigeration storage device.
[051] The transparent display device 20 may include a transparent display panel 24 displaying a predetermined image 26 on a screen, and a frame 22 supporting the periphery of the transparent display panel 24.
[052] In addition, the transparent display device 20 may include a power supply to provide a power source, where the power supply may be arranged in a cover unit 30 located at the lower end of the predetermined product 10.
[053] In this case, the transparent display device 20 which includes the frame 22 and the transparent display panel 24 can be rotatably moved by a hinge fixed to one side of the product 10.
[054] Therefore, the frame 22 and the transparent display panel 24 of the transparent display device 20 can be rotatably moved, and the power supply of the transparent display device 20 can be fixed without rotational movement.
[055] As the case may be, the power supply of the transparent display device 20 can be rotatably moved together with the frame 22 and the transparent display panel 24, depending on where the power supply is arranged.
[056] For example, the transparent display device 20 may include a frame 22, which includes an aperture, a transparent display panel 24 disposed in the aperture, and a control module disposed in the frame zone, controlling the transparent display panel. 24.
[057] In this case, the transparent display panel 24 and the frame 22 where the control module is arranged are provided to cover the front surface of the predetermined product 10, whereby the door unit of the predetermined product 10 can be formed.
[058] Also, the transparent display panel 24 and the frame 22 where the control module is rotatably arranged can be moved when the interior of the predetermined product 10 is opened and closed.
[059] In this case, multiple articles 14 can be displayed on a panel 16 in an internal space 12 of the product 10, and information related to the articles 14 held in the product 10 can be displayed on the transparent display panel 24.
[060] The transparent display panel 24 may include at least one of a liquid-crystal display (LCD), a thin-film transistor-liquid-crystal display (TFT-LCD), an organic light-emitting diode (OLED), a flexible display and a 3D display, and can be configured in a transparent type or light transmitting type to allow a user to view a back side through at least one included in the transparent display panel 24.
[061] A prime example of transparent display panel 24 includes a transparent OLED (TOLED). The transparent display panel 24 can be configured on a back frame or a light transmitting frame, and according to that structure, a user can view an object located on the back of the transparent display device through a zone reserved by the display panel. transparent display 24.
[062] The transparent display device may include two transparent display panels 24, according to its modality type. For example, several transparent display panels 24 can be separated from each other on one surface or they can be arranged in a single body, or they can be arranged on their respective surfaces different from each other.
[063] Furthermore, if the transparent display panel 24 and a touch sensor are formed in a mutual layer structure or formed into a single body, the transparent display panel 24 can be used as an input device in addition to an output device.
[064] In that case, if the touch sensor is a kind of a touch-sensitive film, a touch-sensitive sheet, a touch-sensitive plate, etc., for example, the touch sensor can be deposited on the display panel transparent 24 forming a layered structure. The touch sensor and transparent display panel 24 may be formed into a single body such that the touch sensor is included in the transparent display panel 24.
[065] Next, frame 22 may include a front door frame and a rear door frame.
[066] In this case, the front door frame may include a first opening, and the rear door frame may include a second opening. An area of the first opening can be different from the area of the second opening.
[067] For example, the area of the second opening of the rear door frame can be wider than that of the first opening of the front door frame.
[068] This is because more interior space is required to provide a light source module on an interior side of the tailgate frame.
[069] If the area of the second opening of the tailgate frame is narrower than that of the first opening of the front door frame, since the light source module provided on the inner side of the tailgate frame may be exposed to the outside, it is preferred that the area of the second opening of the rear door frame is wider than that of the first opening of the front door frame.
[070] In addition, the front door frame may include an extension frame. The extension frame can be extended towards the tailgate frame, and it can be fixed to the tailgate frame.
[071] The extension frame can be provided with a line space through which a connecting line passes.
[072] In this case, the reason that the line space for passing through the connection line is formed in the extension frame is that the connection line electrically connects the transparent display panel 24 located above the control module with the module control located below the transparent display panel 24.
[073] Subsequently, the tailgate frame can be fixed to a buffer element arranged in one direction of the product 10.
[074] This is because impact damage between frame 22 and product 10 should be avoided.
[075] For example, the tailgate frame can be provided with at least one fixing hole in one direction of the product 10, and the plug element can be provided with a fixing projection towards the tailgate frame.
[076] In this case, the fixing projection of the buffer element can be fixed inside the fixing hole of the tailgate frame.
[077] In addition, the tailgate frame may include at least one light source module disposed in a side area facing the second opening.
[078] In this case, the light source module can be longer than a side length of the transparent display panel 24.
[079] This is because the light generated from the light source module determines the luminance within the transparent display panel 24 and the product 10.
[080] If the length of the light source module is shorter than the side length of the transparent display panel, the luminance within the transparent display panel 24 and the product 10 may deteriorate.
[081] Then problems may occur that an image displayed on the transparent display panel 24 is not clear and the articles 14 displayed in the internal space of the product 10 cannot be seen from the outside.
[082] In addition, the transparent display device 20 may further include a first transparent cover and a second transparent cover.
[083] In that case, the first transparent cover can be arranged in a first gap from the front surface of the transparent display panel 24, and the second transparent cover can be arranged in a second gap from the rear surface of the display panel transparent 24.
[084] For example, the first range and the second range may be different from each other, and the first range may be wider than the second range.
[085] This is to protect the transparent display panel 24 from external impact.
[086] If the first gap is narrower than the second gap, a gap between the first outermost transparent cover and the transparent display panel 24 becomes narrow, as the external impact can easily be transferred to the transparent display panel 24. For this reason, the transparent display panel 24 can be damaged by external impact.
[087] In addition, a first air gap may be formed between the first transparent cover and the front surface of the transparent display panel 24 by the first gap, and a second air gap may be formed between the second transparent cover and the surface back of the transparent display panel 24 by the second interval.
[088] This is because moisture is generated by a temperature difference between the transparent display panel 24 and the first and second transparent covers and can adversely affect the transparent display panel 24 to deteriorate its lifespan.
[089] As appropriate, a blower can be arranged in frame 22 to emit heat generated from the control module towards the rear surface of the transparent display panel 24.
[090] In this case, the blower can flow the air with heat towards the rear surface of the transparent display panel 24, according to a control signal from the control module, to the extent that the moisture in the air gap can be removed.
[091] For example, a humidity sensor to detect the humidity in the air gap can be arranged in frame 22. The control module can control the blower by receiving a detection signal from the humidity sensor.
[092] That is, the control module can control the blower to turn it on if the humidity in the air gap is high and to turn it off if the humidity in the air gap is low.
[093] So, in accordance with the present invention, the transparent display panel can be prevented from being adversely affected by moisture, as the life of the transparent display panel can be increased.
[094] The first transparent cover may be made of a different material than the second transparent cover.
[095] In that case, the first transparent cover can be made of a front tempered glass material, and the second transparent cover can be made of a back insulating material.
[096] This is because the first outermost transparent cover should be protected from external impact and the second transparent cover should prevent external heat from permeating into the product 10, such as a refrigerator.
[097] As appropriate, the first transparent cover and the second transparent cover can be made of various materials depending on their functions.
[098] An anti-reflective coating (AR) film can be formed on a front surface of the clear cover.
[099] This is because the luminance and contrast of an image displayed on the transparent display panel 24 may deteriorate if external light is reflected towards the transparent cover.
[0100] Also, the corner areas of the first and second clear cover can adhere to frame 22.
[0101] Subsequently, a first spacer and a second spacer can be arranged in the corner areas of the first and second transparent cover.
[0102] In that case, the first spacer can control a gap between the first and second transparent cover and a gap between the first transparent cover and the transparent display panel 24.
[0103] And, the second spacer can control a gap between the second transparent cover and the transparent display panel 24.
[0104] For example, the first spacer may include the first and second support bars and the first and second connecting bars.
[0105] In that case, the first support bar can control the gap between the first and second transparent cover, and the second support bar can control the gap between the first transparent cover and the transparent display panel 24.
[0106] The first connecting bar can connect a side end of the first support bar with a side end of the second support bar and can be in contact with the corner area of the first transparent cover, and the second connecting bar can be connected to the other side end of the first support bar and can be in contact with the corner area of the second clear cover.
[0107] Also, the control module is arranged in the area of the frame 22 located external to the first and second transparent covers, and can be provided with an insulating coating film formed on its external surface.
[0108] If the control module is arranged in the area of frame 22 located outside the first and second transparent covers, the circuit parts included in the control module can be easily repaired and replaced with others. If the insulating coating film is formed on the outer surface, the control module can be prevented from being damaged by temperature and humidity in a cooling environment.
[0109] For example, the control module may include a first interface unit for receiving a signal from an external device, a second interface unit for receiving a signal from a remote control, and a control for controlling the transparent display panel 24 according to the signals received from the first and second interface units.
[0110] In this case, the first interface unit can connect the external device with the transparent display device 20.
[0111] In this case, the first interface unit can be connected to the external device, such as Digital Versatile Disc (DVD), Blu-ray, gaming device, camera, camcorder, computer (eg notebook computer), etc. via wired/wireless cables.
[0112] The first interface unit can route video, audio, or data signal, which is externally input through the external device connected thereto, to the transparent display device control module 20. Furthermore, the first unit interface can output video, audio or data signal processed by the control module to the external device.
[0113] For this purpose, the first interface unit may include an A/V input/output unit (not shown) or a wireless communication unit (not shown).
[0114] The A/V input/output unit may include a USB terminal, a composite video sync terminal (CVBS), a component terminal, an S-video (analog) terminal, a digital visual interface terminal ( DVI), a high-definition multimedia interface (HDMI) terminal, an RGB terminal, and a D-SUB terminal, for inputting video and audio signals from the external device to the transparent display device 20.
[0115] The wireless communication unit can perform short-range wireless communication with other electronic devices.
[0116] Subsequently, the transparent display device 20 can be connected with other electronic devices via the network in accordance with communication standards such as Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Broadband (UWB), ZigBee, Alliance for Digital Home Networks (DLNA), etc.
[0117] Also, the second interface unit can route a signal input by a user to the control module, or it can route the signal from the control module to the user.
[0118] For example, the second interface unit can receive a control signal such as power on/off and screen setting from a remote control and input gesture and audio information through the remote control according to various modes of operation. communication, such as RF (Radio Frequency) communication mode and IR communication mode, or can transmit the control signal from the control module to the remote controller.
[0119] Also, for example, the second interface unit can route a control signal input by a local key (not shown), such as an on/off key, a volume key, and a configuration key , for the control module.
[0120] The remote control is intended to transmit a user input to the second interface unit, and can use Bluetooth, RF (Radio Frequency) communication, infrared (IR) communication, UWB (Ultra Wide Band), ZigBee mode, etc.
[0121] In addition, the remote control can receive video, audio or data signal output from the second interface unit and can display the signal received through it or output audio or vibration.
[0122] As appropriate, the control module may also include a third interface unit for wired/wireless network connection.
[0123] In this case, the third interface unit can be connected to multiple TV internet connection devices through at least one of the above mentioned multiple terminals to perform input/output operation with the devices and TV internet connection .
[0124] The third interface unit can provide an interface to connect the transparent display device 20 with wired/wireless networks, including Internet network. The third interface unit may include an Ethernet terminal, eg for wired network connection. For example, communication standards such as Wireless LAN (WLAN) (Wi-Fi), Wireless Broadband (Wibro), Worldwide Interoperability for Microwave Access (Wimax), and High Speed Downlink Packet Access (HSDPA), can be used for wireless network connection.
[0125] Subsequently, the third interface unit can transmit or receive data to or from another user or other electronic device over the connected network or another network connected to the connected network.
[0126] As another case, the control module may further include an audio output unit to output the processed audio signal from the control.
[0127] In this case, the audio output unit can receive an audio signal processed by the control module, for example, a stereo signal, a 3.1 channel signal or a 5.1 channel signal, and output the received signal as audio . The audio output unit can be configured as one of several speaker types.
[0128] In addition, the control module can control the luminance of the transparent display panel 24 when the frame 22 is rotatably moved to open the predetermined product 10.
[0129] The control module can control the transparent display panel 24 to display information related to the articles 14 held in the predetermined product 10.
[0130] Subsequently, the control module can control the transparent display panel 24 to simultaneously display a transmissive area where light is transmitted and a non-transmissive area where light is not transmitted.
[0131] In this case, the control module can control the transparent display panel 24 to display information related to the articles 14 held in the predetermined product 10 in the non-transmissive area.
[0132] As the case may be, the control module can control the transparent display panel 24 to display information related to the items 14 viewed through the transmissive area between the items 14 held in the predetermined product 10, in the non-transmissive area.
[0133] The transparent display device 20 may further include the cover unit 30 which includes a power supply to provide a power source for the transparent display panel 24 and the control module.
[0134] In that case, the cover unit 30 can be arranged to be separated from the frame 22 at a predetermined interval and can be attached to the lower end of the predetermined product 10.
[0135] Also, the lid unit 30 can be attached to the lower end of the predetermined product 10 when the frame 22 is rotatably moved to open and close the predetermined product 10.
[0136] As the case may be, the cover unit 30 may further include an audio output unit for outputting the processed audio signal from the control module.
[0137] As described above, according to the present invention, the frame in which the transparent display panel and the control module are arranged is provided to cover the front surface of the predetermined product and rotatably moved when the interior of the product is opened. and closed, in that the frame can serve as a door unit and at the same time perform various functions such as article information on the product and advertising.

[0145] In that case, the frame may include an opening, and the transparent display panel 210 may be disposed in the opening of the frame.
[0146] The control module 260 can be arranged in the frame area located outside the transparent display panel 210 to control it.
[0147] Furthermore, the frame on which the transparent display panel 210 and the control module 260 are arranged can be provided to cover the front surface of the predetermined product to form a door unit of the predetermined product, and can be moved so rotating when the interior of the predetermined product is opened and closed.
[0148] Subsequently, the frame may include a front door frame 220 and a rear door frame 230.
[0149] In that case, the front door frame 220 may form a rectangular frame by combining a left frame 222, a right frame 224, an upper frame 226 and a lower frame 229 with each other, and may form a first opening in the center.
[0150] The back door frame 230 can form a second opening in the center, and can be connected to the front door frame 220.
[0151] At this time, an area of the first opening may be different from the area of the second opening.
[0152] For example, the area of the second opening of the back door frame 230 may be wider than that of the first opening of the front door frame 220.
[0153] This is because more interior space is required to provide a light source module 250 on an inner side of the tailgate frame 230.
[0154] If the area of the second opening of the back door frame 230 is narrower than that of the first opening of the front door frame 220, since the light source module 250 is provided on the inner side of the back door frame 230 can be exposed to the outside, it is preferred that the area of the second opening of the back door frame 230 is wider than that of the first opening of the front door frame 220.
[0155] In addition, the front door frame 220 may include an extension frame 224. The extension frame 224 may be extended towards the rear door frame 230, and may be attached to the rear door frame 230.
[0156] Extension frame 224 may be provided with a line space 222 through which a connecting line 266 passes.
[0157] In this case, the reason that the line space 222 to pass the connection line 226 is formed in the extension frame 224 is that the connection line 226 electrically connects the transparent display panel 210 located above the control module 260 with the control module 260 located below the transparent display panel 210.
[0158] Thereafter, the tailgate frame 230 may be attached to a buffer element 240 at the rear where the predetermined product is arranged.
[0159] This is because impact damage between the tailgate frame 230 and the predetermined product must be avoided.
[0160] For example, the tailgate frame 230 may be provided with at least one mounting hole in the rear, and the plug element 240 may be provided with a mounting projection 242 towards the tailgate frame 230.
[0161] In this case, the fixing projection 242 of the buffer element 240 can be fixed to the fixing hole of the tailgate frame 230.
[0162] And, the tailgate frame 230 may include at least one light source module 250 disposed in a side area facing the second opening.
[0163] Subsequently, a hinge 310, a frame plate 340, a cover plate 320 covering the control module 260, which includes a main board 262 and a t-con 264, and a back door frame 330 can still be disposed between the front door frame 220 and the back door frame 230.
[0164] In that case, the hinge 310 may be arranged in a corner area of the front door frame 220, and the frame plate 340 and control module 260 may be arranged to correspond to a lower frame 228 of the frame. front door 220.
[0165] The cover plate 320 and the back door frame 330 can be arranged to correspond respectively to the upper frame 226 and the lower frame 228 of the front door frame 220.
[0166] Also, the first transparent cover 270 can be arranged in a first gap from the front surface of the transparent display panel 210, and the second transparent cover 280 can be arranged in a second gap from the rear surface of the display panel 216. transparent display 210.
[0167] For example, the first range and the second range may be different from each other, and the first range may be wider than the second range.
[0168] This is to protect the transparent display panel 210 from external impact.
[0169] If the first gap is narrower than the second gap, a gap between the outermost first transparent cover 270 and the transparent display panel 210 becomes narrow, as the external impact can easily be transferred to the transparent display panel 210. For this reason, the transparent display panel 210 can be damaged by external impact.
[0170] Also, a first air gap can be formed between the first transparent cover 270 and the front surface of the transparent display panel 210 by the first gap, and a second air gap can be formed between the second transparent cover 280 and the rear surface of the transparent display panel 210 by the second interval.
[0171] This is because this moisture is generated by a temperature difference between the transparent display panel 210 and the first and second transparent cover 270 and 280 and can adversely affect the transparent display panel 210 to deteriorate the life of the panel transparent display 210.
[0172] The first clear cover 270 may be made of a different material than the second clear cover 280.
[0173] In that case, the first transparent cover 270 can be made of a front tempered glass material, and the second transparent cover 280 can be made of a back insulating material.
[0174] This is because the outermost first clear cover 270 should be protected from external impact and the second clear cover 280 should prevent external heat from permeating into the product, such as a refrigerator.
[0175] As the case may be, the first transparent cover 270 and the second transparent cover 280 can be made of various materials depending on their functions.
[0176] An anti-reflective coating (AR) film can be formed on a front surface of the first clear cover 270.
[0177] This is because the luminance and contrast of an image displayed on the transparent display panel 210 may deteriorate if external light is reflected towards the transparent cover.
[0178] Also, the corner areas of the first and second clear cover 270 and 280 can adhere to the front door frame 220 and the back door frame 230.
[0179] Subsequently, a first spacer 290 and a second spacer 300 may be arranged in the corner areas of the first and second transparent covers 270 and 280.
[0180] In that case, the first spacer 290 can control a gap between the first and second transparent cover 270 and 280 and a gap between the first transparent cover 270 and the transparent display panel 210.
[0181] And, the second spacer 300 can control a gap between the second transparent cover 280 and the transparent display panel 210.
[0182] Figure 4 is a view illustrating a front door frame and a rear door frame of Figure 2.
[0183] As shown in Figure 4, the front door frame 220 can form a rectangular frame and can form a first opening 221 in the center.
[0184] The back door frame 230 may form a second opening 231 in the center, and may be connected to the front door frame 220.
[0185] At that time, an area of the first opening 221 may be different from the area of the second opening 231. The area of the second opening 231 of the tailgate frame 230 may be wider than the area of the first opening 221 of the door frame front 220.
[0186] This is because more interior space is required to provide a light source module on an interior side of the 230 tailgate frame.
[0187] If the area of the second opening 231 of the back door frame 230 is narrower than that of the first opening 221 of the front door frame 220, since the light source module is provided on the inner side of the door frame 230 can be exposed to the outside, it is preferred that the area of the second opening 231 of the back door frame 230 is wider than that of the first opening 221 of the front door frame 220.
[0188] The widths w1 and w2 of the left and right frame bars 220a and 220b of the front door frame 220 are equal to each other, and the widths w3 and w4 of the upper and lower frame bars 220c and 220d of the front door frame 220 are equal to each other.
[0189] The width w3 and w4 of the top and bottom frame bars 220c and 220d of the front door frame 220 may be greater than the widths w1 and w2 of the left and right frame bars 220a and 220b of the front door frame 220 .
[0190] This is because circuit boards, such as a control module, can be provided in the area of the upper and lower frame bars 220c and 220d of the front door frame 220.
[0191] Several lines connected to the control module can be arranged in the areas of the left and right frame bars 230a and 230b of the tailgate frame 230.
[0192] Also, the widths w11 and w12 of the left and right frame bars 230a and 230b of the tailgate frame 230 are equal to each other, and the widths w13 and w14 of the upper and lower frame bars 230c and 230d of the tailgate frame tailgate 230 are equal to each other.
[0193] The width w11 and w12 of the left and right frame bars 230a and 230b of the tailgate frame 230 may be the same as the widths w13 and w14 of the upper and lower frame bars 230c and 230d.
[0194] Figure 5 is a view illustrating a process of attaching a front door frame, a back door frame and a buffer element of Figure 2.
[0195] As shown in Figure 5, the tailgate frame 230 can be attached to the rear of the front gate frame 220, and the buffer element 240 may be attached to the rear of the tailgate frame 230.
[0196] In that case, the front door frame 220 may include an extension frame 224. The extension frame 224 may be extended towards the rear gate frame 230, and may be attached to the rear gate frame 230.
[0197] At this time, the extension frame 224 can be fixed to the tailgate frame 230 by an adhesive or a fixing screw.
[0198] Extension frame 224 may be provided with a line space 222 through which a connecting line 266 passes.
[0199] Subsequently, the tailgate frame 230 can be fixed to a buffer element 240.
[0200] This is because impact damage between the tailgate frame 230 and the predetermined product should be avoided.
[0201] In this case, the tailgate frame 230 may be provided with at least one fixing hole 232 at the rear, and the plug element 240 may be provided with a retaining projection 242 towards the tailgate frame 230.
[0202] In that case, the fixing projection 242 of the buffer element 240 can be fixed to the fixing hole 232 of the tailgate frame 230.
[0203] Figure 6 is a view illustrating a process of arranging a light source module of Figure 2.
[0204] As shown in Figure 6, the light source module 250 can be arranged on an inner side of the tailgate frame 230.
[0205] In that case, the light source module 250 may include a substrate 251 having an electrode pattern, and at least one light source 252 disposed on the substrate 251.
[0206] At that time, a light source 252 of the light source module 250 may be a top view type light emitting diode.
[0207] As the case may be, the light source 252 may be a side view type light emitting diode.
[0208] Substrate 251 can be a printed circuit board (PCB) made of any material selected from PET, glass, PC, and Si, or it can be formed from a type of film.
[0209] In addition, a single-layer PCB, a multi-layer PCB, a ceramic substrate, a metal core PCB, etc. can be selectively used as the 251 substrate.
[0210] In that case, either of a reflective coating film and a layer of reflective coating material can be formed on the substrate 251, and the substrate 251 can transmit the light generated by the light source 252 to the transparent display panel. .
[0211] Subsequently, the light source 252 can be a light-emitting diode (LED) chip that can be configured as a blue LED chip and an ultraviolet LED chip, or it can be configured as a package type obtained by combining of at least one or more than one red LED chip, one green LED chip, one blue LED chip, one yellow green LED chip and one white LED chip.
[0212] The white LED can be realized by combining a yellow phosphor on the blue LED, it can be done using a red phosphor and a green phosphor on the blue LED, or it can be done by simultaneously using a yellow phosphor, a phosphor red and a green phosphor on the blue LED.
[0213] Also, the light source module 250 can be attached to all the left and right frame bars 230a and 230b of the tailgate frame 230 and the upper and lower frame bars 230c and 230d of the tailgate frame 230 , or can be fixed to some of them, as the case may be.
[0214] For example, the light source module 250 can be at least any one of the first, second and third light source modules 250a, 250b and 250c.
[0215] In that case, the first light source module 250a can be arranged on the inner side of the left frame bar 230a of the back door frame 230, and the second light source module 250b can be arranged on the inner side of the bar. right frame 230b from the tailgate frame 230.
[0216] At that time, the first light source module 250a disposed on the left frame bar 230a of the tailgate frame 230 and the second light source module 250b disposed on the right frame bar 230b of the tailgate frame 230 may be facing each other.
[0217] The third light source module 250c can be arranged on the inner side of the upper frame bar 230c of the tailgate frame 230.
[0218] At this time, the third light source module 250c may be disposed on the inner side of the upper frame bar 230c of the tailgate frame 230 and may face the lower frame bar 230d of the tailgate frame 230.
[0219] Also, the light sources 252 of the light source module 250 may be powered simultaneously as a substrate 251 is disposed along the side of the tailgate frame 230.
[0220] As the case may be, as multiple substrates 251 are arranged along the side of the tailgate frame 230, the light sources 252 of the light source module 250, which are arranged on each substrate 251, can be driven individually.
[0221] Figure 7 is a view illustrating a length of a light source module of Figure 2.
[0222] As shown in Figure 7, the light source module 250 may be disposed along the contour of the transparent display panel 210 being supported by the inner side of the tailgate frame.
[0223] In that case, the light source module 250 may include a substrate 251 having an electrode pattern, and at least one light source 252 disposed on the substrate 251.
[0224] In this case, the light source module 250 may be longer than the side length of the transparent display panel 210.
[0225] This is because the light generated from the light source module 250 determines the luminance of the transparent display panel 24 and the internal space of the product.
[0226] If the length of the light source module 250 is shorter than the side length of the transparent display panel 210, the luminance of the transparent display panel 24 and the internal space of the product may deteriorate.
[0227] In this way, problems may occur as an image displayed on the transparent display panel 210 is not clear and the articles displayed in the internal space of the product cannot be seen from the outside.
[0228] For example, the light source module 250 can be at least any of the first, second and third light source modules 250a, 250b and 250c.
[0229] In that case, the first light source module 250a can be arranged around the left side of the transparent display panel 210, and the second light source module 250b can be arranged around the right side of the display panel transparent 210.
[0230] The third light source module 250c can be arranged around the upper side of the transparent display panel 210.
[0231] In that case, a length L1 of the first light source module 250a can be greater than a left length L11 of the transparent display panel 210, and a length L2 of the second light source module 250b can be greater than a right length L12 of the transparent display panel 210.
[0232] Subsequently, a length L3 of the third light source module 250c may be greater than a longer length L13 of the transparent display panel 210.
[0233] Also, the length L1 of the first light source module 250a may be the same as the length L2 of the second light source module 250b.
[0234] And, the length L3 of the third light source module 250c may be smaller than the length L1 of the first light source module 250a and the length L2 of the second light source module 250b.
[0235] Figure 8 is a view illustrating the arrangement of the first and second transparent cover of Figure 2.
[0236] As shown in Figure 8, the transparent display device may further include a first transparent cover 270 and a second transparent cover 280.
[0237] In that case, the first transparent cover 270 can be arranged in a first gap D1 from the front surface of the transparent display panel 210, and the second transparent cover 280 can be arranged in a second gap D2 from the rear surface of the transparent display panel 210.
[0238] For example, the first interval d1 and the second interval d2 can be different from each other, and the first interval d1 can be greater than the second interval d2.
[0239] This is to protect the transparent display panel 210 from external impact.
[0240] If the first gap d1 is narrower than the second gap d2, a gap between the outermost first transparent cover 270 and the transparent display panel 210 becomes narrow, as external impact can easily be transferred to the transparent display panel 210. For that reason, the transparent display panel 210 can be damaged by external impact.
[0241] Further, a first air gap may be formed between the first clear cover 270 and the front surface of the clear display panel 210 by the first gap d1, and a second air gap may be formed between the second clear cover 280 and the back surface of the transparent display panel 210 by the second gap d2.
[0242] This is because moisture is generated by a temperature difference between the transparent display panel 210 and the first and second transparent cover 270 and 280 and can adversely affect the transparent display panel 210 to deteriorate the life of the same .
[0243] The first clear cover 270 may be made of a different material than the second clear cover 280.
[0244] In that case, the first transparent cover 270 can be made of a front tempered glass material, and the second transparent cover 280 can be made of a back insulating material.
[0245] This is because the outermost first clear cover 270 should be protected from external impact and the second clear cover 280 should prevent external heat from permeating into the product, such as a refrigerator.
[0246] As the case may be, the first transparent cover 270 and the second transparent cover 280 can be made of various materials depending on their functions.
[0247] An anti-reflective coating (AR) film can be formed on a front surface of the first clear cover 270.
[0248] This is because the luminance and contrast of an image displayed on the transparent display panel 210 can deteriorate if external light is reflected towards the first transparent cover 270.
[0249] Subsequently, a first spacer 290 can control a gap between the first and second transparent cover 270 and 280, and a second spacer 300 can control a gap between the second transparent cover 280 and the transparent display panel 210.
[0250] Next, a corner area of the first clear cover 270 may be in contact with the front door frame 220, and a corner area of the second clear cover 280 may be in contact with the back door frame 230.
[0251] The light source module 250 can be arranged in the rear corner area of the second clear cover 280 being supported by the back door frame 230.
[0252] Additionally, a buffer element 240 may be disposed on the rear surface of the tailgate frame 230, and a line 266 for electrically connecting the control module with the transparent display panel 210 may be arranged in a line space of the frame. front door 220.
[0253] Figure 9 is a view illustrating the first and second spacers of Figure 2.
[0254] As shown in Figure 9, the first spacer 290 and the second spacer 300 can be arranged in the corner areas of the first and second transparent covers 270 and 280.
[0255] In that case, the first spacer 290 can control the gap between the first and second transparent cover 270 and 280 and the gap between the first transparent cover 270 and the transparent display panel 210.
[0256] And, the second spacer 300 can control the gap between the second transparent cover 280 and the transparent display panel 210.
[0257] For example, the first spacer 290 may include the first and second support bars 294 and 292 and the first and second connecting bars 296 and 298.
[0258] In that case, the first support bar 294 can control the gap between the first and second transparent cover 270 and 280, and the second support bar 292 can control the gap between the first transparent cover 270 and the display panel transparent 210.
[0259] The first connecting bar 296 can connect a side end of the first support bar 294 with a side end of the second support bar 292 and can be in contact with the corner area of the first transparent cover 170, and the second bar connector 298 can be connected to the other side end of the first support bar 294 and can be in contact with the corner area of the second transparent cover 280.
[0260] Then, according to the present invention, since the air gap between the first and second transparent cover 270 and 280 and the transparent display panel 210 can be stably maintained by the first and second spacers 290 and 300, humidity due to a temperature difference can be minimized.
[0261] Figure 10 is a view illustrating the arrangement of a control module of Figure 2, and Figure 11 is a schematic view in blocks illustrating a control module of Figure 2.
[0262] As shown in Figures 10 and 11, the transparent display device 20 may be provided to a front surface portion of a predetermined product 10, such as a refrigerator, to serve as a door unit of the predetermined product 10.
[0263] In that case, the predetermined product 10 may be a refrigeration storage device, such as a refrigerator. The predetermined product 10 can be a storage device that can hold multiple items or it can be a digital signage without limitation to the refrigeration storage device.
[0264] The transparent display device 20 may include a transparent display panel 24 displaying a predetermined image 26 on a screen, and a frame 22 supporting the periphery of the transparent display panel 24.
[0265] In addition, the transparent display device 20 may include a power supply to provide a power source, where the power supply 600 may be arranged in a cover unit 30 located at the lower end of the predetermined product 10.
[0266] In that case, the transparent display device 20 which includes the frame 22 and the transparent display panel 24 can be rotatably moved by a hinge fixed to one side of the product 10.
[0267] Therefore, the frame 22 and the transparent display panel 24 of the transparent display device 20 can be rotatably moved by the hinge, and the power supply 600 of the transparent display device 20 can be fixed without rotational movement.
[0268] As the case may be, the power supply 600 of the transparent display device 20 can be rotatably moved together with the frame 22 and the transparent display panel 24, depending on where the power supply 600 is arranged.
[0269] Also, the control module 500 can be provided with an insulating coating film formed on its outer surface.
[0270] If the control module 500 is arranged in the area of the frame 22 located on the outside of the transparent panel 24, circuit parts included in the control module 500 can be easily repaired and replaced by others. If the insulating coating film is formed on the outer surface, the control module 500 can be prevented from being damaged by temperature and humidity in a cooling environment.
[0271] For example, as shown in Figure 11, the control module 500 may include a first interface unit 510 for receiving a signal from an external device, a second interface unit 520 for receiving a signal from an external device. remote control, and a control 540 for controlling the transparent display panel 24 in accordance with the signals received from the first and second interface units 510 and 520.
[0272] In this case, the first interface unit 510 can connect the external device with the transparent display device 20.
[0273] In this case, the first interface unit 510 can be connected to the external device such as Digital Versatile Disc (DVD), Blu-ray, gaming device, camera, camcorder, computer (e.g. notebook computer), etc. via wired/wireless cables.
[0274] The first interface unit 510 can route video, audio, or data signal, which is externally input through the external device connected thereto, to the control 540. In addition, the first interface unit 510 can output the signal video, audio, or data processed by the 540 control to the external device.
[0275] For that purpose, the first interface unit 510 may include an A/V input/output unit (not shown) or a wireless communication unit (not shown).
[0276] The A/V input/output unit may include a USB terminal, a composite video sync terminal (CVBS), a component terminal, an S-video (analog) terminal, a Digital Visual Interface terminal (DVI), a high-definition multimedia interface (HDMI) terminal, an RGB terminal, a D-SUB terminal, etc., for inputting the audio and video signals from the external device to the transparent display device 20.
[0277] The wireless communication unit can perform short-range wireless communication with other electronic devices.
[0278] Subsequently, the transparent display device 20 can be connected with the other electronic devices through the network according to communication standards, such as Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Band ultra wide (UWB), ZigBee, Alliance for Digital Home Networks (DLNA), etc.
[0279] In addition, the second interface unit 520 may forward a signal entered by a user to the control 540, or may forward the signal from the control 540 to the user.
[0280] For example, the second interface unit 520 can receive a control signal such as on/off and screen setting from a remote control and gesture and audio information input through the remote control according to various communication modes, such as RF (radio frequency) communication mode and IR communication mode, or it can transmit the control signal from the control module to the remote controller.
[0281] In addition, for example, the second interface unit 520 can forward a control signal input by a local key (not shown) such as a power key, a volume key, and a setup key to the control. 540.
[0282] The remote control is intended to transmit user input to the second 520 interface unit, and can use Bluetooth, RF (Radio Frequency) communication, Infrared (IR) ray communication, UWB (Ultra Wide Band), ZigBee mode , etc.
[0283] In addition, the remote control can receive video, audio or data signal output from the second interface unit 520 and display the signal received through it or output audio or vibration.
[0284] As appropriate, the control module 500 may further include a third interface unit 530 for wired/wireless network connection.
[0285] In this case, the third interface unit 530 can be connected to multiple TV internet connection devices through at least one of the several terminals mentioned above to perform input/output operation with the internet connection devices TV.
[0286] The third interface unit 530 can provide an interface to connect the transparent display device 20 with wired/wireless networks including the Internet network. The third interface unit 530 may include an Ethernet terminal, for example, for wired network connection. For example, communication standards such as Wireless LAN (WLAN) (Wi-Fi), Wireless Broadband (Wibro), Worldwide Interoperability for Microwave Access (Wimax), and High Downlink Packet Access Speed (HSDPA), can be used for wireless network connection.
[0287] Subsequently, the third interface unit 530 can transmit or receive data to or from another user or other electronic device over the connected network or another network connected to the connected network.
[0288] As another case, the control module 500 may further include an audio output unit 550 for outputting the processed audio signal from the control 540.
[0289] In this case, the audio output unit 550 can receive an audio signal processed by the control module, for example, a stereo signal, a 3.1 channel signal, or a 5.1 channel signal, and output the received signal as audio. The 550 audio output unit can be configured as one of several speaker types.
[0290] Depending on the case, the audio output unit 550 can be arranged in the cover unit 30 being separate from the control module 500.
[0291] Figure 12 is a view that illustrates the line connection of a control module of Figure 2.
