Abstract

A screen assembly includes a display region, a light sensor arranged within the display region and configured to acquire data representing ambient light of the screen assembly, and a data transmission wire coupled to the light sensor at one end and a processing component at another end. The data transmission wire is configured to transmit the data acquired by the light sensor to the processing component.

Claims

1. A screen assembly, comprising:

a display region;

a light sensor arranged within the display region and configured to acquire data representing ambient light of the screen assembly; and

a data transmission wire coupled to the light sensor at one end and a processing component at another end, and configured to transmit the data acquired by the light sensor to the processing component.

2. The screen assembly according to claim 1, further comprising:

a touch screen structure having a conductive layer that contains a plurality of electrodes arranged in accordance with a preset pattern,

wherein a vertical projection of the light sensor is located within a vertical projection of a gap among some of the electrodes.

3. The screen assembly according to claim 2, wherein the light sensor is made of a transparent material.

4. The screen assembly according to claim 2, further comprising:

a glass panel; and

an LCD display module,

wherein;

the touch screen structure is arranged between the glass panel and the LCD display module, and

the light sensor is arranged in the touch screen structure, between the touch screen structure and the glass panel, or between the touch screen structure and the LCD display module.

5. The screen assembly according to claim 2, further comprising:

a glass panel; and

an LCD display module,

wherein;

the touch screen structure is embedded in the LCD display module, and

the light sensor is arranged in the touch screen structure.

6. The screen assembly according to claim 1, further comprising:

an LCD display module,

wherein a vertical projection of the light sensor is located within a vertical projection of a black matrix region of a sub-pixel of the LCD display module.

7. The screen assembly according to claim 1, wherein the screen assembly includes a plurality of evenly-arranged light sensors.

8. A mobile device, comprising a screen assembly according to claim 1.

9. The mobile device according to claim 8, wherein the screen assembly further includes a touch screen structure having a conductive layer that contains a plurality of electrodes arranged in accordance with a preset pattern, a vertical projection of the light sensor being located within a vertical projection of a gap among some of the electrodes.

10. The mobile device according to claim 9, wherein the light sensor is made of transparent material.

11. The mobile device according to claim 9, wherein the screen assembly further includes a glass panel and an LCD display module, the touch screen structure being arranged between the glass panel and the LCD display module, and the light sensor being arranged in the touch screen structure, between the touch screen structure and the glass panel, or between the touch screen structure and the LCD display module.

12. The mobile device according to claim 9, wherein the screen assembly further includes a glass panel and an LCD display module, the touch screen structure being embedded in the LCD display module, and the light sensor being arranged in the touch screen structure.

13. The mobile device according to claim 8, wherein the screen assembly further includes an LCD display module, a vertical projection of the light sensor being located within a vertical projection of a black matrix region of a sub-pixel of the LCD display module.

14. The mobile device according to claim 8, wherein the screen assembly includes a plurality of evenly-arranged light sensors.
