Liquid Crystal Display Touch Screen Array Substrate and the Corresponding Liquid Crystal Display Touch Screen

摘要

The present invention discloses a liquid crystal display touch screen array substrate, which comprises multiple pixel units defined by a gate line and a data line, each pixel unit is provided with a thin film transistor and a pixel electrode inside; the array substrate further comprises: a touch circuit unit used for touch positioning, the touch circuit unit comprising a touch emission line and a touch sensing line intersecting each other, and a light sensing unit provided at the intersection and respectively connected to the touch emission line and the touch sensing line. The touch emission line is the gate line, the touch sensing line is a dummy data line provided on the array substrate, and the dummy data line and the adjacent data line are separated by at least one pixel electrode. The embodiment of the present invention correspondingly discloses a liquid crystal display touch screen. According to the embodiment of the present invention, it can increase the opening ratio, enhance the sensitivity of touch positioning, and improve the product yield.
