[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] This application proposes a touch screen that can automatically adjust light intensity, please refer to Figure 1 and Figure 2 , including a light sensor 10, a circuit board 30 and a display assembly 20. The light sensor 10 is used to sense light intensity. The display assembly 20 is provided with a display area 23 and a non-display area 24. The display area 23 is used to display images, and the non-display area 24 is used to protect the display area 23 and connect the circuit board 30. An ink layer is provided on the non-display area 24 to enhance the aesthetics of the touch screen. In addition, a hollow opening is provided on the ink layer, and a light-transmitting semi-transparent film layer is silk-screened on the hollow opening. The circuit board 30 is connected to the non-display area 24 on the display assembly 20. A through hole is provided on the circuit board 30. The light sensor 10 is provided on the through hole of the circuit board 30 and is electrically connected to the circuit board 30. The light outside the touch screen is sequentially sensed by the semi-transparent film layer and the through hole by the light sensor 10, so that the structure of the touch screen is compact, the safety is high, and a certain amount of use space is reduced, thereby ensuring that the touch screen has the function of sensing light intensity by itself, and adjusting the brightness of the backlight through the sensed light intensity data, so that the brightness on the touch screen reaches a preset value to meet the user's viewing experience. The hollow openings are usually in the shape of holes, openings or stripes arranged at intervals.

[0025] It should be noted that when the touch screen is working, the light sensor 10 senses the brightness of the light irradiated by the touch screen, that is, the display brightness on the display component 20. The light sensor 10 transmits the sensed light intensity data to the control center of the touch screen. The control center processes and analyzes the light intensity data sensed by the light sensor 10, and then compares it with the preset brightness to determine how the control center should adjust the brightness of the backlight, thereby achieving the effect of adjusting the brightness of the touch screen.

[0026] In one embodiment, see Figure 1A photosensitive protective film layer 11 is provided between the photosensitive sensor 10 and the circuit board 30 to protect the photosensitive sensor 10 so that the photosensitive sensor 10 can be exempted from certain external damage. Preferably, the display assembly 20 includes a cover plate 21 and a touch glass 22, the cover plate 21 is bonded and connected to the touch glass 22, and the circuit board 30 is bonded below the cover plate 21 and the touch glass 22. In another embodiment, the circuit board 30 is an FPC, and a component area 31 is provided on the FPC, and the component area 31 is used to weld components. A steel sheet is provided on the back of the component area 31 of the FPC, and the steel sheet is used to reinforce the component area 31. When the components are welded in the component area 31, the FPC is soft in texture, but the component area 31 is heavy, so the steel sheet is needed to provide certain support for the FPC, and the thickness of the steel sheet used for reinforcement is 0.2 mm. Furthermore, the display assembly 20 also includes optical glue. Since the optical glue has good light transmittance, the cover plate 21 and the touch glass 22 are bonded by the optical glue, thereby ensuring the connection between the cover plate 21 and the touch glass 22, while ensuring the display effect. Specifically, the optical glue is OCA glue or OCR glue. In addition, the touch screen of the present application also includes a double-sided adhesive block, and the double-sided adhesive block is provided with a through groove. The light sensor 10 is bonded to the circuit board 30 through the double-sided adhesive block, and the through hole is connected to the through groove. External light irradiates the light sensor 10 through the through hole and the through groove. Among them, the thickness of the double-sided adhesive block is 0.05mm.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
