Problems solved by technology

The existing touch screen adds a photosensitive chip on the circuit board, and in order to improve the detection accuracy, it is usually required to add a structural light guide column and a sealing ring around the photosensitive chip on the circuit board, and the structure is relatively complicated.
In use, generally only the capacitance and resistance changes generated after touch can be fed back

Embodiment Construction

[0023] Such as figure 1 As shown, the touch screen device provided by the present invention includes a touch screen, a touch screen connector (CTP connector) and a main control circuit, the touch screen is provided with a photosensitive layer 1, one end of the photosensitive layer is grounded, and the other end leads a wire to connect to On the touch screen connector, the output end of the touch screen connector is connected to the main control circuit, and the main control circuit controls the touch screen. It only needs to add a small optical sensitive layer to the ordinary touch screen, one end is grounded, and one end leads a line to the touch screen connector. The specific composition and area of ​​the optically sensitive layer depends on the project.

[0024] Such as figure 2 , the touch screen connector is connected to the main control circuit, and after real-time detection by the main control circuit, the display brightness of the display part is controlled to impro...

Abstract

The invention relates to a touch screen with a light sensing function. The touch screen comprises a touch screen body, a touch screen body connector and a master control circuit. A light sensitive layer is arranged on the touch screen body, one end of the light sensitive layer is grounded, a wire is led out of the other end of the light sensitive layer and is connected onto the touch screen body connector, an output end of the touch screen body connector is connected with the master control circuit, and the touch screen body is controlled by the master control circuit. The touch screen with the light sensing function has the advantages that the display brightness of terminal equipment can be automatically adjusted according to change of external visible light intensity in service procedures, accordingly, individual detection circuits on circuit boards can be omitted, the usability of mobile terminals can be improved, and the touch screen is excellent in operational convenience and cost superiority.

Description

technical field [0001] The invention relates to a touch screen with light-sensing function and an application method thereof. Background technique [0002] Touch screens are widely used in mobile phones, tablets and other handheld or small display devices. The existing touch screen adds a photosensitive chip on the circuit board, and in order to improve the detection accuracy, it is usually required to add a structural light guide column and a sealing ring around the photosensitive chip on the circuit board, and the structure is relatively complicated. In use, generally only the capacitance and resistance changes generated after touching can be fed back. [0003] Such a design is very common. If a sensing area made of optically sensitive materials is added to the touch screen, the function of the touch screen can be increased, the use of a separate photosensitive chip on the circuit board can be reduced, the cost can be reduced, and the convenience of use can be improved fo...
