Touch-control photosensitive structure for preventing red light leakage

Abstract

A touch-control photosensitive structure for preventing red light leakage includes a metal substrate, an insulating layer, a photosensitive layer, a third metal layer and a transparent conductive layer. The insulating layer is disposed on the metal substrate. The photosensitive layer is disposed on the insulating layer. The photosensitive layer at least comprises red photosensitive blocks, green photosensitive blocks and blue photosensitive blocks, arranged alternately. A junction region is disposed at the junction of the photosensitive blocks in different colors. The third metal layer is disposed on the junction region. The third metal layer has a lower surface which a light absorption layer is disposed on. The light absorption layer absorbs a reflecting light otherwise reflecting off the metal substrate and the third metal layer and propagating therebetween. The transparent conductive layer is disposed on the third metal layer. The third metal layer reduces impedance of the transparent conductive layer efficiently and thereby renders public voltage stable. The light absorption layer absorbs the reflecting light and thereby prevents light leakage.
