It is evident that the described modalities are only some, but not all, of the present invention. All other modalities obtained by those skilled in the art based on the modalities of the present invention and obtained without any creative effort will fall within the scope of protection of the present invention.

The above terminal can be a mobile phone or it can be a user's laptop or similar. It should be noted that the embodiments of the present invention do not impose any limitations on a color of a terminal housing. It is preferable that one color of one part of the terminal housing may be white, and another part may be of another color. A color of a front area of a mobile phone housing, for example, can be white and a color of a rear part of the terminal housing and a color of a side surface of a part connecting the front housing and the rear housing can be white or it can be another color. Reference can be made to a white mobile phone shown in Figure 1. To facilitate the description of the technical solutions in this application, a white mobile phone is used as an example in all subsequent embodiments of the present invention.
[039] When an existing terminal (the white mobile phone shown in Figure 1, for example) is on standby, a display screen, a front camera and a light sensor device are all black and another area of the display device of a front housing is white. Consequently, for some users who have a high demand for color, the visual experience is degraded.
[040] Figure 2 is a structural schematic diagram of a terminal of variable colors according to the present invention. The terminal includes: a touch screen 11, a display screen 12, a circuit board 13, and a liquid crystal film for light adjustment 14. The touch screen 11 is located above the display screen 12. A a circuit board 13 is located below the display screen 12, and a circuit board 13 includes a drive circuit 15. The liquid crystal film for the light adjustment 14 is arranged on the touch screen 11. The circuit drive 15 is configured to apply a control voltage to the liquid crystal film for light adjustment 14; when an amplitude of the control voltage is greater than or equal to a predetermined threshold, the liquid crystal film for the light adjustment 14 is in a transparent state; or when an amplitude of the control voltage is less than the predetermined threshold, the liquid crystal film for the light adjustment 14 is in a non-transparent state; and a color of the liquid crystal film for the adjustment of light 14 in the non-transparent state is different from a color of the display screen 12.
[041] Specifically, as shown in Figure 2, touch screen 11 is located above display screen 12, and circuit board 13 is located below display screen 12. The terms "above" and "below" at present they can be defined according to a coordinate system shown in Figure 2. A touch screen coordinate value 11 on the x axis is less than a coordinate value on the display screen 12 on the x axis, which indicates that touch screen 11 is located above display screen 12; a coordinate value of a circuit board 13 on the x axis is greater than the coordinate value of the display screen 12 on the x axis, which indicates that the circuit board 13 is located below the display screen 12 In addition, the concepts of "upper" and "lower" involved in the present invention can be defined according to the coordinate system shown in Figure 2.
[042] In the embodiment of the present invention, the liquid crystal film for the light adjustment 14 is arranged on the touch screen 11. It should be noted that, in Figure 2, the liquid crystal film for the light adjustment 14 is shown as a separate layer, to display the liquid crystal film for light adjustment 14 more clearly, which is simply used as an example in this embodiment of the present invention. In this embodiment of the present invention, a position of the liquid crystal film for the light adjustment 14 is not limited to the position shown in Figure 2, provided that the liquid crystal film for the light adjustment 14 corresponds to the touch screen 11. A liquid crystal film for light adjustment 14 can include a first transparent film (film) 21 and a second film 22, a layer of indium tin oxide (Indium Tin Oxide, abbreviated ITO) is applied by sputtering on the two opposite surfaces of the first film 21 and the second film 22, and is filled with a liquid crystal material between the two layers of ITO films 23 formed to form a liquid crystal layer 24. The five layers constitute the liquid crystal film for the 14 light adjustment as a whole. For the structure of the liquid crystal film for the light adjustment 14, you can refer to Figure 3. It should be noted that the liquid crystal film for the light adjustment 14 may be an integral part of the touch screen 11, or else it can be separated from the touch screen 11 and finally connected to the touch screen 11. It should be noted that Figure 3 shows only an example of a position relationship between the liquid crystal film for the light adjustment 14 and the touch screen 11.
[043] The drive circuit 15 on a Jew's circuit board 13 above is used to apply a control voltage to the liquid crystal film for light adjustment 14. Optionally, the drive circuit 15 can determine, according to a actual operating condition of a terminal, a value of the control voltage to be applied to the liquid crystal film for light adjustment 14; the drive circuit 15 can determine, for example, according to a switching signal generated inside the terminal, the value of the control voltage to be applied to the liquid crystal film for light adjustment 14, or it can determine, according to According to an instruction from a terminal processor, the value of the control voltage to be applied to the liquid crystal film for light adjustment 14. Optionally, the control voltage can consist of a direct current voltage or it can be a voltage alternating current.
[044] Optionally, when the display screen 12 of the terminal is working, the drive circuit 15 applies a control voltage to the liquid crystal film for light adjustment 14 whose amplitude is greater than or equal to a predetermined threshold ( in fact, the drive circuit 15 applies the control voltage to the two layers of ITO films 23 of the liquid crystal film for light adjustment 14). According to the structure of the liquid crystal film for the light adjustment 14 and which is shown in Figure 3, when the amplitude of the control voltage applied to the upper and lower layers of the ITO 23 films is greater than or equal to the predetermined threshold , the liquid crystal molecules in the liquid crystal layer 24 of the liquid crystal film for light adjustment 14 are regularly arranged along an electric field direction of the control voltage, so that the light can penetrate. Therefore, the liquid crystal film for the light adjustment 14 is in a transparent state; in this case, a terminal appearance is the same as that of the existing terminal in use. When the display screen 12 of the terminal is not working, the drive circuit 15 applies, to the liquid crystal film for the light adjustment 14, a control voltage whose amplitude is less than the predetermined threshold; according to the structure that is that of the liquid crystal film for the light adjustment 14 and which is shown in Figure 3, when the amplitude of the control voltage applied to the upper and lower layers of the ITO films 23 is below the predetermined threshold , the liquid crystal molecules in the liquid crystal layer 24 of the liquid crystal film for light adjustment 14 are arranged irregularly, so that the light is dispersed by the liquid crystal molecules which are irregularly arranged. Therefore, the liquid crystal film for the light adjustment 14 is in a non-transparent state, and a color of the liquid crystal film for the light adjustment 14 in the non-transparent state is different from a color of the display screen 12; optionally, the apparent color of the liquid crystal film for the adjustment of light 14 in the non-transparent state is white. Therefore, if the white mobile phone shown in Figure 1 is used as an example, when the liquid crystal film for the light adjustment 14 is in the non-transparent state, the apparent color of the touch screen 11 is white; as touch screen 11 is located Austria, 18/43 with Rub —---— c> & I above the viewing screen 12, from a user's perspective, the viewing pain 12 of the viewing screen 12 is white ; that is, when the display screen 12 of the white mobile phone is not functioning, an apparent color of the integral front housing of the terminal is white, thus satisfying a requirement for the appearance of the user's terminal and improving the visual experience of the user. It should be noted that this embodiment of the present invention does not impose any limitations on the color of the terminal housing. If the terminal housing is of a different color, when the display screen 12 of the terminal proposed in this embodiment of the present invention is not working, the apparent color of the display screen 12 will be different from that of a display screen 12 that is not working in the prior art, thus also improving the visual user experience.
[045] According to the variable color terminal proposed in this embodiment of the present invention, a liquid crystal film for the adjustment of light corresponding to a touch screen is arranged on the touch screen; a drive circuit applies a control voltage to the liquid crystal film for light adjustment and when an amplitude of the applied control voltage is greater than or equal to a predetermined threshold, the liquid crystal film for light adjustment is in a transparent state, or when an amplitude of the applied control voltage is less than the predetermined threshold, the liquid crystal film for the light adjustment is in a non-transparent state. Therefore, when a terminal display screen is not working, an apparent color of the display screen will be different from that of a display screen that is not working in the prior art, thus satisfying a user's terminal appearance requirement and improving the experience. visual of the user.
[046] In addition, the touch screen 11 above may include a glass cover 111 and a touch function layer 112.
[047] Optionally, the liquid crystal film for the light adjustment 14 can be arranged on the upper surface of the glass lid 111; that is, the liquid crystal film for the light adjustment 14 is coated or applied by sputtering on the upper surface of the glass lid 111 in the form of a separate layer. For details, you can refer to a terminal structure in the modality shown in Figure 4.
[048] Optionally, the liquid crystal film for light adjustment 14 can also be arranged on the bottom surface of the touch function layer 112; that is, coated or sputtered onto the underside of the touch function layer 112 in the form of a separate layer. For details, it can refer to a terminal structure in a modality shown in figure 5.
[049] Optionally, the liquid crystal film for light adjustment 14 can also be arranged between the glass cover 111 and the touch function layer 112; optionally, the liquid crystal film for light adjustment 14 can be arranged between the glass cover 111 and the touch function layer 112 in the form of a separate layer and for details, it can refer to the structure of a terminal in a modality shown in Figure 6; and the liquid crystal film for the light adjustment 14 can be integrated with the touch screen 11. «Austria, ry O <c Fts è Ruc the touch function layer 112 of the touch screen 11 includes sensor layers of upper touch and lower, the upper touch sensor layer including a third film 25 (a material of the third film 25 can be glass, plastic or other material), and a layer of ITO film 23 is coated on a lower surface of the third film 25; and including the lower touch sensor layer a fourth film 26 (a material of the fourth film 26 may be glass, plastic or another material), and the ITO layer 23 being coated on an upper surface of the fourth film 26. Therefore, only a liquid crystal material needs to be used to fill the space between the two layers of ITO films 23, then the liquid crystal film for light adjustment 14 and the touch screen 11 are integrated. That is, the third film 25 above is equivalent to the first film 21 of the liquid crystal film for the light adjustment 14, the fourth film 26 is equivalent to the second film 22 of the liquid crystal film for the light adjustment 14 and the two layers of ITO films 23 of the touch sensor layer are equivalent to the two layers of ITO films 23 of the liquid crystal film for light adjustment 14; that is, the liquid crystal film for light adjustment 14 shares the films and the ITO films 23 which are of the touch sensing layer. For details, it can refer to a terminal structure in a modality shown in Figure 7.
[050] In addition, the driving circuit 15 already mentioned includes a first driving circuit 151, and the liquid crystal film for the light adjustment 14 mentioned above includes a first area 141, corresponding to the first area 21/4 3 f '“-EèL_A fb ε rt Rub __O - QJ I 141 to the display screen 12, and the first drive circuit 151 is configured to apply a control voltage to the first area 141; the aforementioned circuit board 13 further includes a central processing unit 16, the central processing unit 16 being configured to detect whether the display screen 12 is off; the central processing unit 16 is further configured, when it is detected that the display screen 12 is switched off, to control the first drive circuit 151 to apply to the first area 141, a control voltage whose amplitude is less than the predetermined threshold, being that the control voltage whose amplitude is less than the predetermined threshold enables the first area 141 to be in a non-transparent state; and the central processing unit 16 still being configured, when it is detected that the display screen 12 is on, to control the first drive circuit 151 to apply a control voltage whose amplitude is greater than or equal to the first area 141 predetermined threshold, and the voltage whose amplitude is greater than or equal to the predetermined threshold enables the first area 141 to be in a transparent state.
[051] Specifically, the drive circuit 15 mentioned above includes a first drive circuit 151, and can refer to a structure of a circuit board 13 shown in Figure 8. The liquid crystal film for the light adjustment 14 mentioned above includes a first area 141, the first area 141 corresponding to the display screen 12; for details, it can refer to a liquid crystal film structure for the cf & ty adjustment (light 14 shown in Figure 9. The first area can be implemented using an engraving process. That is, an ITO pattern corresponding to the screen visualization 12 is engraved on the two layers of ITO films 23 on the liquid crystal film for the light adjustment 14 mentioned above, and the ITO standard is the first area 141. A layer of paint is applied on another part excluding the first area 141, on the ITO 23 film, on an internal surface of the film, for the white mobile phone shown in figure 1, an ink color is white.
[052] When it is detected that the display screen 12 is on, the central processing unit 16 controls the first drive circuit 151 mentioned above to apply to the first area 141, a control voltage whose amplitude is greater than or equal to the predetermined threshold , and the control voltage whose amplitude is greater than or equal to the predetermined threshold enables the first area 141 to be in the transparent state; in this case, a terminal appearance is the same as a terminal appearance there are in use.
[053] When it is detected that the display screen 12 is switched off, the central processing unit 16 controls the first drive circuit 151 mentioned above to apply, to the first area 141, a control voltage whose amplitude is less than the predetermined threshold, the control voltage whose amplitude is less than the predetermined threshold enables the first area 141 to be in the non-transparent state; a color of the first area 141 in the non-transparent state is different from a color of the display screen 12, and optionally, when the first area 141 is in the non-transparent state, an apparent color of the first area 141 can be white. Therefore, if the white mobile phone shown in Figure 1 is used as an example, when the first area 141 is in the non-transparent state, the apparent color of the first area 141 is white. Since the touch screen 11 is located above the display screen 12, from a user's perspective, an appearance of the display screen 12 is also white; that is, when the display screen 12 of the white mobile phone is off, an apparent color of the full front housing of the terminal will be white (for details, it can refer to a white appearance diagram of a terminal shown in Figure 10 ), thus satisfying a user's terminal appearance requirement and improving the visual user experience. It should be noted that this embodiment of the present invention does not impose any limitations on the color of the terminal housing. If the terminal housing is of a different color, when the display screen 12 of the terminal proposed in this embodiment of the present invention is turned off, the apparent color of the display screen 12 will be different from that of a display screen 12 which is switched off in the art above, thus also improving the visual user experience.
[054] It should be noted that Figure 9 shows only an example of a position relationship between the liquid crystal film for the light adjustment 14 and the touch screen 11; the technical solution in this embodiment of the present invention is applicable to positions of the liquid crystal film for any of the terminal structures shown in Figures 4 to 7 above.

Therefore, when the display screen of the terminal is turned off, an apparent color of the display screen is different from an apparent color of the display screen that is turned off in the prior art, thus satisfying a user's requirement regarding the appearance of the terminal and improving the visual user experience.

The liquid crystal film for the light adjustment 14 also includes a second area 142, the second area 142 corresponding to the front camera 17. The second drive circuit 152 is configured to apply a control voltage to the second area 142. The central processing unit 16 is further configured, after detecting that the display screen 12 is on, to receive an instruction used to turn on the camera front 17, and to control the second drive circuit 152 to apply a control voltage whose amplitude is greater than or equal to the predetermined threshold to the second area 142, the control voltage whose amplitude is greater than or equal to the predetermined threshold enables the second area 142 to be in a transparent state.The central processing unit 16 is further configured, when no instructions used to turn on the front camera 17 are detected, to control the eg second drive circuit 152 to apply a control voltage whose amplitude is less than the predetermined threshold to the second area 142, and the control voltage whose amplitude is less than the predetermined threshold enables the second area 142 to be in a state not transparent.
[057] Specifically, as shown in Figure 11, the drive circuit 15 mentioned can also include a second drive circuit 152; in addition to the first area 141, the liquid crystal film for the light adjustment 14 may also include a second area 142, the second area 142 corresponding to the front camera 17. The second area 142 can be implemented using an engraving process, That is, an ITO pattern corresponding to the front camera 17 is engraved on the two layers of ITO films 23 on the liquid crystal film for the aforementioned light adjustment 14, and the ITO pattern is the second area 142. A layer of paint it is applied in another part excluding the first area 141 and the second area 142, on the ITO film 23 on an internal surface of the film; for the mobile phone shown in Figure 1, an ink color is white.
[058] After having detected that the display screen 12 is on, the central processing unit 16 receives an instruction that is used to turn on the front camera 17 and which is sent by the terminal; optionally, the central processing unit 16 can determine whether the instruction used to turn on the front camera 17 is received by detecting whether a voltage level value on the pin of the central processing unit 16 changes. Upon receiving the instruction used to turn on the front camera 17, the central processing unit 16 controls the drive circuit according to 152 mentioned above to apply, in the second area 142, a control voltage whose amplitude is greater than or equal to the predetermined threshold, being that the control voltage whose amplitude is greater than or equal to the predetermined threshold enables the second area 142 to be in the transparent state; in this case, an appearance of the terminal is the same as an appearance of an existing terminal in use.
[059] When no instruction used to turn on the front camera 17 has been detected, the central processing unit 16 controls the second drive circuit 152 above to apply to the second area 142, a control voltage whose amplitude is less than the predetermined threshold , and the control voltage whose amplitude - Rüb is less than the predetermined threshold, enables the safety of area 142 to be in the non-transparent state; optionally, when the second area 142 is in the non-transparent state, an apparent color of the second area 142 can be white. Therefore, if the white mobile phone shown in Figure 1 is used as an example, a transparent area is arranged in a position that is opposite to the front camera 17 and this is on the touch screen 11. In the prior art, when the front camera 17 is off, from a user's perspective, an apparent color of the transparent area is black; however, in this embodiment of the present invention, the second area 142 is actually opposite the position of the transparent area, and the second area 142 and the transparent area have the same shape and the same size, therefore, when the second area 142 meets in the non-transparent state, from the user's perspective, the apparent color of the transparent area is white. In addition, when the front camera 17 of the white mobile phone is off and the display screen 12 is off, the apparent color of the entire front housing of the terminal is white (for details, it can refer to the white appearance effect diagram of a terminal shown in Figure 12), thus satisfying a user requirement regarding the appearance of the terminal and improving the visual user experience. It should be noted that this embodiment of the present invention does not impose any limitations on the color of the terminal housing. If the terminal housing is of a different color, when the front camera 17 of the terminal proposed in this embodiment of the present invention is turned off, an apparent color of a transparent area that is opposite to the front camera 17 and that Rub • O is found on the touch screen 11 is different from a color of the eN i $ 3 'transparent area when the front camera 17 is turned off in the prior art, thus also improving the visual experience of the user.
[060] It should be noted that Figure 11 shows only an example of a position relationship between the liquid crystal film for the light adjustment 14 and the touch screen 11; the technical solution in this embodiment of the present invention is applicable to positions of the liquid crystal film for light adjustment 14 and the touch screen 11 which are found in any of the terminal structures shown in Figures 4 to 7 mentioned above.
[061] According to the variable color terminal proposed in this embodiment of the present invention, a liquid crystal film for adjusting the light corresponding to a touch screen is arranged on the touch screen, and a second area corresponding to a camera front is engraved on a layer of ITO film from the liquid crystal film for light adjustment when no instruction used to turn on the front camera is detected, a central processing unit controls a second drive circuit to apply to the second area , a control voltage whose amplitude is below a predetermined threshold, to enable the second area to be in a non-transparent state. Therefore, when the front camera of the terminal is distilled, an apparent color of a transparent area that is opposite to the front camera and that is on the touch screen is different from an apparent color of the transparent area when the front camera is turned off in the technique previous one, thus satisfying one and improving the visual user experience.
[062] Figure 13 is a schematic structural diagram of a terminal of variable colors according to another embodiment of the present invention. Based on the aforementioned modalities, moreover, as shown in Figure 13, the mentioned terminal can further include a light sensor 18, the light sensor 18 being arranged on a circuit board 13; the drive circuit 15 further includes a third drive circuit 153, and the liquid crystal film for the light adjustment 14 further includes a third area 143, the third area 143 corresponding to the light sensor 18, and the third drive circuit 153 is configured to apply a control voltage to the third area 143; the central processing unit 16 is further configured, after it has been detected that the display screen 12 is on, to receive an instruction used to turn on the light sensor 18, and to control the third drive circuit 153 to apply to the third area 143, a control voltage whose amplitude is greater than or equal to the predetermined threshold, whereas the control voltage whose amplitude is greater than or equal to the predetermined threshold enables the third area 143 to be in a transparent state; and the central processing unit 16 is further configured; when no instruction used to turn on the light sensor 18 has been detected, to control the third drive circuit 153 to apply to the third area 143 a control voltage whose amplitude is below the predetermined threshold, the control voltage being whose amplitude is less than the predetermined threshold enables the third ^ s '"a' O / 30/43 2 /% g Fis y / y 1 Rut f • o Á % area 143 to be in a non-transparent state.
[063] Specifically, as shown in figure 13, the driving circuit 15 mentioned above can also include a third driving circuit 153; in addition to the first area 141 and the second area 142, the liquid crystal film for the light adjustment 14 mentioned above may also include a third area 143, corresponding to the third area 143 with the light sensor 18. The third area 143 can be implemented using an engraving process. That is, an ITO pattern corresponding to the light sensor 18 is engraved on the two layers of ITO films 23 on the liquid crystal film for the light adjustment 14 mentioned above, and the ITO pattern is the third area 143. One layer of ink is coated on another part, excluding the first area 141, the second area 142, and the third area 143, on the ITO film 23 on an internal surface of the film; for the white mobile phone shown in the Figure, an ink color is white.
[064] After detecting that the display screen 12 is on, the central processing unit 16 receives an instruction that is used to turn on the light sensor 18 and which is sent by the terminal; optionally, the central processing unit 16 can determine whether the instruction used to connect the light sensor 18 is received, detecting whether a pin voltage level value of the central processing unit 16 changes. When it receives the instruction used to turn on the light sensor 18, the central processing unit 16 controls the third drive circuit 153 mentioned above to apply to the third area 143 a control voltage whose amplitude is greater than or equal to the predetermined threshold, where the voltage of f § Fis JrL.— <«Rut> -% / amplitude is greater than or equal to the predetermined threshold enables the third area 143 to be in the transparent state; in this case an appearance of the terminal is the same as an appearance of an existing terminal in use.
[065] When no instruction used to connect the light sensor 18 has been detected, the central processing unit 16 controls the third drive circuit 153 mentioned above to apply to the third area 143, a control voltage whose amplitude is less than predetermined threshold, where the control voltage whose amplitude is less than the predetermined threshold enables the third area 143 to be in the non-transparent state; optionally, when the third area 143 is in the non-transparent state, an apparent color of the third area 143 can be white. Therefore, if the white mobile phone shown in Figure 1 is used as an example, a transparent area is arranged in a position that is opposite the light sensor 18 and which is located on the touch screen 11. In the prior art, when the light sensor 18 is off, from a user's perspective, the apparent color of the transparent area is black; however, in this embodiment of the present invention, the third area 143 is actually opposite the position of the transparent area, and the third area 143 and the transparent area have the same shape and the same size, therefore, when the third area 143 meets in the non-transparent state, from the user's perspective, the apparent color of the transparent area is white. In addition, when both the light sensor 18 and the front camera 17 of the white mobile phone are off, and the display screen 12 is off, an apparent color of the full front housing of the terminal is white (for details, refer to a white appearance effect diagram for a terminal shown in figure 14), thus satisfying a user requirement regarding the appearance of the terminal and improving the visual experience of the user. It should be noted that this embodiment of the present invention does not impose any limitations on the color of the terminal housing. If the terminal housing is of a different color, when the light sensor 18 of the terminal proposed in this embodiment of the present invention is turned off, an apparent color of a transparent area that is opposite to the light sensor 18 and which is on the screen touch 11 is different from a color of the transparent area when the light sensor 18 is turned off in the prior art, thus also improving the visual experience of the user.
[066] It should be noted that Figure 13 shows only an example of a position relationship between the liquid crystal film for the light adjustment 14 and the touch screen 11; the technical solution in this embodiment of the present invention is applicable to positions of the liquid crystal film for the light adjustment 14 and the touch screen 11 which are found in any of the terminal structures shown in Figures 4 to 7 mentioned above. In addition, the terminal shown in figure 13 which includes a viewing screen 12, a front camera 17, and a light sensor 18 is just one example. A structure in which a terminal includes only a display screen 12 and a light sensor 18 is not shown, but an implementation principle is analogous to that of the modality shown in figure 13, and the details will not be described in this document.
[067] According to the variable color terminal proposed in this modality of the present invention, liquid crystal for the adjustment of light corresponding to a touch screen is arranged on the touch screen, and a third area corresponding to a light sensor it is engraved on a layer of ITO film of the liquid crystal film for light adjustment; when no instruction used to turn on the light sensor is detected, a central processing unit controls a third drive circuit to apply a control voltage to the third area whose amplitude is less than a predetermined threshold, to enable the third area to find yourself in a non-transparent state. Therefore, when the light sensor of the terminal is turned off, an apparent color of a transparent area that is opposite to the light sensor and that is on the touch screen is different from an apparent color of the transparent area when the light sensor is disconnected in the prior art, thus satisfying a user's requirement regarding the appearance of the terminal and improving the user's visual experience.
[068] Figure 15 is a schematic structural diagram of a terminal of variable colors according to another embodiment of the present invention. Based on the aforementioned modalities shown in Figures 1 to 7, in addition, the aforementioned terminal can also include: a switch 19, configured to receive user inputs, in order to generate a control signal that is used to turn the viewing screen 12; the circuit board 13 also includes a fourth drive circuit 154, configured to control, according to the control signal generated by the switch 19, the display screen 12 to connect or x / stria / 34/43, / s ™ —E 2 CJ% Rut) - £> t'Q & e / ij 1 hang up; the fourth drive circuit 154 being electrically connected to switch 19; in a case where switch 19 generates a control signal which is used to control the display screen 12 to switch on, the fourth drive circuit 154 applies a control signal to the liquid crystal film for light adjustment 14 whose control voltage is greater than or equal to the predetermined threshold; and in a case where switch 19 generates a control signal which is used to control the display screen 12 to switch off, the fourth drive circuit 154 applies, to the liquid crystal film for light adjustment 14, a voltage of control whose amplitude is below the predetermined threshold.
[069] Specifically, when receiving the user input, the switch 19 disposed in the terminal generates a control signal that is used to control the display screen 12 to switch on or off, and transmits the control signal to the fourth drive circuit 154 ; when receiving the control signal, the fourth drive circuit 154 controls the display screen 12 to switch on or off.
[070] When the control signal is used to switch on the display screen 12, the fourth drive circuit 154 applies, to the liquid crystal film for light adjustment 14, a control voltage whose amplitude is greater than or equal to the threshold predetermined. Therefore, the liquid crystal film for the light adjustment 14 on the touch screen 11 is in the transparent state; in this case, an appearance of the terminal is the same as an appearance of an existing terminal in use.
[071] When the control signal is used to turn off the display screen 12, the fourth drive circuit 154 applies, to the liquid crystal film for the light adjustment 14, a control voltage whose amplitude is less than the predetermined threshold. Therefore, the liquid crystal film for the light adjustment 14 is in the non-transparent state; a color of the liquid crystal film for the light adjustment 14 in the non-transparent state is different from a color of the display screen 12, and optionally, when the liquid crystal film for the light adjustment 14 is in the non-transparent state, an apparent color of the liquid crystal film for light adjustment 14 is white. Therefore, if the white mobile phone shown in Figure 1 is used as an example, when the liquid crystal film for the light adjustment 14 is in the non-transparent state, the apparent color of the touch screen 11 is white; since the touch screen 11 is located above the display screen 12, from a user's perspective, the apparent color of the display screen 12 is white; that is, when the display screen 12 of the white mobile phone is switched off, an apparent color of the integral front housing of the terminal is white, satisfying a user requirement regarding the appearance of the terminal and thus also improving the visual experience of the user. It should be noted that this embodiment of the present invention does not impose any limitations on the color of the terminal housing. If the terminal housing is of a different color, when the display screen 12 of the terminal proposed in this embodiment of the present invention is not working, the apparent color of the display screen 12 will be different from that of a display screen 12 that is not working in the prior art, thereby improving
[072] It should be noted that Figure 15 shows only an example of a position relationship between the liquid crystal film for the light adjustment 14 and the touch screen 11; the technical solution in this embodiment of the present invention is applicable to positions of the liquid crystal film for the adjustment of light 14 and the touch screen 11 which are found in any of the terminal structures shown in Figures 4 to 7 mentioned above.
[073] According to the variable color terminal proposed in this embodiment of the present invention, a switch that is used to control a display screen to turn on or off is disposed on the terminal and the switch is electrically connected to a fourth drive circuit; when a control signal generated by the aforementioned switch is used to control the display screen to turn off, the fourth drive circuit applies, to a liquid crystal film for light adjustment, a control voltage that is less than a predetermined threshold , so that the liquid crystal film for the light adjustment is in a non-transparent state. Therefore, when a display screen of the terminal is turned off, an apparent color of the display screen is different from that of a display screen that is turned off in the prior art, thus satisfying a user requirement regarding the appearance of the terminal and improving the visual user experience.
[074] Figure 16 is a schematic structural diagram of a terminal of variable colors according to another embodiment of the present invention. As shown in figure 16, the terminal includes: a housing 30, the housing 30 being partially or totally transparent; a circuit board 13, the circuit board 13 being located inside the housing 30, and including the circuit board 13 a drive circuit 15; a liquid crystal film for the light adjustment 14, the liquid crystal film for the light adjustment 14 being located inside the housing 30 and covering a transparent area of the housing 30; and a liner 31, the liner 31 being located in the entire housing 30 and the liner 31 and the transparent area of the housing 30 being located, respectively, on both sides of the liquid crystal film for the light adjustment 14. The drive circuit 15 is configured to apply a control voltage to the liquid crystal film for light adjustment 14; when an amplitude of the control voltage is greater than or equal to a predetermined threshold, the liquid crystal film for the light adjustment 14 is in a transparent state, or when an amplitude of the control voltage is less than the predetermined threshold, the film liquid crystal for light adjustment 14 is in a non-transparent state; and a color of the liquid crystal film for the adjustment of light 14 in the non-transparent state is different from a color of the coating 31.
[075] Specifically, the housing 30 of the terminal in this embodiment of the present invention is entirely transparent or partially transparent, the housing 30 can be a rear housing of the terminal or a housing involving four sides of a terminal body; the liquid crystal film for the light adjustment 14 is arranged inside the housing 30, and for a structure of the liquid crystal film for the light adjustment 14, it can refer to the structure shown in Figure 3; the liquid crystal film for the light adjustment 14 covers a transparent area of the housing 30, the coating 31 is further arranged inside the housing 30, and the coating 31 and the transparent area of the housing 30 are respectively located on both sides of the film liquid crystal for light adjustment 14; according to a coordinate system shown in figure 16, the liquid crystal film for the light adjustment 14 is arranged on the left side of the housing 30, and the coating 31 is arranged on the left side of the liquid crystal film for the light adjustment 14.
[076] The drive circuit 15 on a circuit board 13 mentioned above is used to apply a control voltage to the liquid crystal film for light adjustment 14. Optionally, the drive circuit 15 can determine, according to a actual operating condition of a terminal a value of the control voltage to be applied to the liquid crystal film for light adjustment 14; the drive circuit 15, for example, can determine, according to a switching signal generated inside the terminator, the value of the control voltage to be applied to the liquid crystal film for light adjustment 14, or can determine, according to an instruction from a terminal processor, the value of the control voltage to be applied to the liquid crystal film for the light setting 14, or else the drive circuit 15 can determine the value of the control voltage by detecting a level of a device in a circuit. Optionally, the control voltage can be a direct current voltage or it can be an alternating current voltage.
[077] When the drive circuit applies, to the liquid crystal film for light adjustment 14, a control voltage whose amplitude is greater than or equal to a predetermined threshold (in fact, the drive circuit applies the control voltage to both layers of ITO films 23 of the liquid crystal film for light adjustment 14). According to the structure of the liquid crystal film for the light adjustment 14 and which is shown in Figure 3, when the amplitude of the control voltage applied to the upper and lower layers of the ITO films 23 is greater than or equal to the threshold predetermined, the liquid crystal molecules in the liquid crystal layer 24 of the liquid crystal film for light adjustment 14 are regularly arranged along an electric field direction of the control voltage, so that the light can penetrate. Therefore, the liquid crystal film for the light adjustment 14 is in a transparent state; in this case an apparent color of the terminal is that of the lining 31 inside the housing 30.
[078] When the drive circuit applies, to the liquid crystal film for light adjustment 14, a control voltage whose amplitude is less than the predetermined threshold, according to the structure that is of the liquid crystal film for the adjustment of light 14 and which is shown in Figure 3, when the amplitude of the control voltage applied to the upper and lower layers of the ITO films 23 is below the predetermined threshold, the liquid crystal molecules in the liquid crystal layer 24 of the liquid crystal film for light adjustment 14 they are arranged irregularly, so that the light is dispersed by the liquid crystal molecules which are irregularly arranged. Therefore, the liquid crystal film for the light adjustment 14 is in a non-transparent state, and a color of the liquid crystal film for the light adjustment 14 in the non-transparent state is different from a color of the coating 31; optionally, the apparent color of the liquid crystal film for the adjustment of light 14 in the non-transparent state is white, i.e. an apparent color of the transparent area of the integral housing 30 of the terminal is white. That is, according to the terminal proposed in this embodiment of the present invention, a color of the housing 30 of the terminal can be changed between the color of the coating 31 and white at any time, thus satisfying a user's requirement regarding the appearance of the terminal and improving the visual user experience.
