Touch-control liquid crystal display panel and manufacturing method thereof as well as touch-control liquid crystal display device

Abstract

The invention provides a touch-control liquid crystal display panel which comprises at least two gate wires and at least two data wires, a second thin film transistor and a third thin film transistor, wherein the gate wires and the data wires are intersected to form pixel regions, and each pixel area is provided with a first thin film transistor and a public voltage input wire, wherein at least one pixel region also comprises a touch-control electrode wire, a reference signal input wire and a reference signal output line; the second thin film transistor is used for controlling the output of areference signal; the third thin film transistor is used for sensing ambient light; in addition, the third thin film transistor outputs an electric signal into the reference signal output wire by thetouch-control electrode wire under the control of the second thin film transistor, and a touch position signal is judged according to the electric signal output by the reference signal output wire. The invention also correspondingly provides a manufacturing method of the touch-control liquid crystal display panel and the touch-control liquid crystal display device comprising the same.

Description
