Problems solved by technology

[0004] At present, the embedded capacitive touch screen is mainly a fully embedded (Full In-Cell, FIC) capacitive touch screen. In the existing FIC capacitive touch screen, the touch electrode and the common electrode are shared, so that the voltage of the common electrode is uniform during the display process. not good
On this basis, since the touch signal is not a positive-negative inversion signal centered on the reference voltag...

Abstract

The invention provides an array substrate, a display device and a driving method thereof and relates to the technical field of touch display. Voltage uniformity and reliability of the display device can be improved. The array substrate comprises a substrate, a grid line and a data line, wherein the grid line and the data line are arranged on the substrate. The grid line and the data line limit a sub-pixel in a cross mode. The sub-pixel comprises a first thin film transistor, a second thin film transistor, a first transparent electrode and a second transparent electrode. A grid of the first thin film transistor is electrically connected with the grid line, a source is electrically connected with the data line, and a drain is electrically connected with the first transparent electrode; a grid of the second thin film transistor is electrically connected with a touch scanning line, a source is electrically connected with a touch lead, and a drain is electrically connected with the second transparent electrode. The first transparent electrode and the second transparent electrode are insulating, and orthographic projections of the first transparent electrode and the second transparent electrode on the substrate are not overlapped.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to an array substrate, a display device and a driving method thereof. Background technique [0002] The embedded capacitive touch screen integrates the touch electrode structure in the display screen, which has the advantages of simple structure, light, thin, and low cost, and has become more and more mainstream technology of touch screens. For example, it is more and more widely used in various portable smart phones in a terminal (such as a mobile phone). [0003] In the embedded capacitive touch screen, it can be divided into On-Cell touch screen and In-Cell touch screen, and the In-Cell touch screen can be divided into composite embedded (Hybrid In-Cell, HIC) capacitive touch screen and fully Embedded (Full In-Cell, FIC) capacitive touch screen. [0004] At present, the embedded capacitive touch screen is mainly a fully embedded (Full In-Cell, FIC) capacitive touc...
