Claim:
1. 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 being provided with a thin film transistor and a pixel electrode inside; wherein, a common electrode line is provided in parallel at the side of each said gate line; the array substrate further comprising: 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 being the common electrode line, and the touch sensing line being parallel with the data line, wherein charges on the touch emission line are conducted to the touch sensing line when the light sensing unit is turned on, wherein the common electrode line and the gate line utilize synchronous second-order driving signal.
