专利说明:

Plasma display device {PLASMA DISPLAY DEVICE}
[5] The present invention relates to a plasma display device, and more particularly, to a plasma display device capable of effectively improving heat radiation efficiency.
[6] In general, a plasma display panel (hereinafter referred to as a 'PDP' for convenience) is an element that excites a phosphor by vacuum ultraviolet rays caused by gas discharge to realize a predetermined image. It is attracting attention as a display device.
[7] Such a PDP includes a chassis base disposed substantially parallel to the PDP, a driving circuit board mounted on the opposite side of the panel attaching surface of the chassis base and connected to the PDP to drive the PDP, a front cover coupled to the PDP side, and a driving circuit. A plasma display device is configured together with a back cover coupled to the side.
[8] In the plasma display device having such a configuration, when the PDP is driven by the driving circuit, noise, EMI, and heat are usually generated according to the driving thereof. Therefore, the back cover serves to prevent noise from leaking out of the device and at the same time to release heat to the outside of the device. For this purpose, a conventional aluminum plate having a thickness of about 1.5 mm is pressed, and A back cover was manufactured by providing a plurality of heat dissipation holes during press working.
[9] However, the vent holes are 4 mm in diameter and 10 cm in length test pins (the test pins are used in the IEC60065 standard, which is a television standard, and the test pins have a diameter of 3 mm and a length of 1.5 cm in the IEC60950 standard, which is a monitor standard. ) Should be formed in the diameter of 3 ~ 5mm because the dangerous voltage (30Vpeak) should not be touched when inserted into the ventilation hole and the EMI and noise generated inside the device should be suppressed to the outside.
[10] Therefore, when the diameters of the ventilation holes are increased to improve the heat radiation efficiency, problems of noise and EMI become large. On the contrary, when the diameters of the ventilation holes are reduced to reduce noise and EMI, there is a problem in the heat radiation efficiency. .
[11] Accordingly, an object of the present invention is to provide a plasma display device which effectively improves heat dissipation efficiency.
[12] The object of the present invention described above,
[13] A chassis base;
[14] A plasma display panel (PDP) attached to a panel attaching surface of the chassis base;
[15] A PDP driving circuit board attached to an opposite side of the panel attaching surface;
[16] A front cover positioned in front of the PDP;
[17] A back cover surrounding the chassis base and positioned at a rear side of the chassis base and having heat dissipation vent holes;
[18] A heat radiating member made of copper provided on the back cover;
[19] It is achieved by a plasma display device comprising a.
[20] The heat radiating member may be formed of a copper sheet or a copper plated film, and the copper sheet or the copper plated film may be installed on an inner surface, an outer surface, an inner surface, and an outer surface of the back cover, respectively.
[21] The back cover having such a heat radiating member has an effect of reducing the temperature inside the apparatus by about 3 ° C by the difference in thermal conductivity. Therefore, it is possible to improve the heat radiation efficiency without increasing the size and number of heat radiation vent holes.
[1] 1 is an exploded perspective view of a plasma display device according to the present invention.
[2] FIG. 2 is a front view of the back cover shown in FIG. 1 seen in the direction of the arrow; FIG.
[3] 3A is a cross-sectional view showing a state in which the copper sheet of the present invention is installed on a back cover.
[4] 3B is a cross-sectional view showing a state in which the copper plating film of the present invention is coated on a back cover.
[22] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[23] 1 is an exploded perspective view of a plasma display device according to the present invention, Figure 2 is a front view of the back cover shown in FIG.
[24] As shown in the figure, the plasma display apparatus 12 fixes the side surface of the PDP 12 and the plasma display panel 12 (hereinafter referred to as 'PDP' for convenience) and the driving circuit board 14 of the PDP 12 (not shown). ) Includes a chassis base (16) mounted thereon, a front cover (18) positioned in front of the PDP (12), and a back cover (20) positioned behind the chassis base (16) while surrounding the chassis base (16). do.
[25] Chassis base 16 is provided with a plurality of bosses (not shown) used to mount drive circuit board 14 toward the surface opposite back cover 20. In addition, the chassis base 16 may be formed with a plurality of strength reinforcing ribs 16 'along the horizontal axis x and vertical axis y directions. In addition, the outer peripheral portion of the chassis base 16 is provided with a plurality of fixing brackets 16 "for integrally coupling the front cover 18 and the back cover 20.
[26] In addition, the inner surface of the front cover 18 facing the PDP 12 is fixedly mounted with a known conductive film filter 18 ′ for preventing static electricity, and the back cover 20 together with the front cover 18. Surrounding the 12 and the chassis base 16 is assembled integrally with the chassis base 16 through the fixing brackets 16 "to form an appearance of the plasma display apparatus.
[27] Here, the back cover 20 is formed by pressing an aluminum plate, and has a plurality of heat dissipation vent holes 20 '. In addition, the inner surface of the back cover 20, the heat radiating member 22 is installed integrally with the back cover 20, the heat radiating member 22 is copper having a heat conductivity of about twice as high as aluminum. It is configured using (copper).
[28] 1 and 3A form a heat radiating member 22 with a copper sheet 22a, and the copper sheet 22a is attached to the inner surface of the back cover 20 using an adhesive 24. FIGS. 3B is a copper plating film 22b formed on the inner surface of the back cover 20 to form the heat radiating member 22.
[29] In this case, the aluminum back cover 20 is formed to a thickness of 1 to 1.5mm, and the copper sheet 22a or the copper plating film 22b is formed to a thickness of 0.3 to 0.8mm.
[30] The plasma display device having such a structure has a higher radiation efficiency than the conventional one due to the difference in thermal conductivity between the copper sheet 22a or the copper plated film 22b and the aluminum back cover 20, so that the temperature inside the device is approximately 3 degrees. There is an effect of reducing the degree of ℃.
[31] In the above description, the heat radiating member 22 is provided on the inner surface of the back cover 20 as an example. However, the heat radiating member 22 may be formed as shown in FIGS. 3A and 3B. It may be provided on the outer surface, or may be provided on both the inner and outer surfaces.
[32] As such, the present invention is not limited to the above-described embodiments, but may be modified and practiced in various ways within the scope of the claims and the detailed description of the invention and the accompanying drawings, and it is natural that the present invention falls within the scope of the present invention. Do.
[33] As described above, the plasma display apparatus according to the present invention can improve the heat dissipation performance while maintaining the diameter and number of heat dissipation vent holes the same as before. Therefore, there is an effect that can prevent the circuit component from malfunctioning due to the heat.
