Optical touch screen and method for manufacturing the same

Abstract

The embodiments of the present invention relate to an optical touch screen, comprising: a substrate; and a transparent first electrode layer, a photosensitive material layer, and a second electrode layer formed on the substrate. The photosensitive material layer is formed in a grid-like structure to isolate the first electrode layer and the second electrode layer and sense light irradiated on the optical touch screen. The embodiments of the present invention also provide a method for manufacturing an optical touch screen. According to the embodiments of the present invention, the position of the light emitted from the light source on the display screen can be determined by sensing the light emitted from the outside light source, so that human-computer interaction for a large-size screen display device can be achieved.
