Abstract

The invention provides an array substrate, a touch control display device and a driving method thereof. The array substrate comprises a grid drive circuit and a touch control drive circuit arranged in a non-display area. The touch control drive circuit comprises multiple stages of touch control selection output units. Each stage of touch control selection output unit comprises two gating signal input ends, and secondary triggering signal output ends of two adjacent shifting registers in the grid drive circuit provide gating signals. The array substrate provides a simplified touch control drive circuit, thereby being easy to realize design of a narrow frame, reducing signal input ends and lowering IC cost. All touch control drive electrodes can be scanned once in each half frame, so that two times of frame frequency of point report rate is realized. The two stage of touch control selection output unit can simultaneously provide touch control signals at two ends of each touch control drive electrode, thereby effectively preventing driving signal attenuation caused by driving signal provision by a single side, and enhancing the intensity of the driving signal.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to an array substrate, a touch control device including the array substrate and a driving method thereof. Background technique [0002] In the existing HybridIn-Cell (Hybrid In-Cell, HIC) touch display screen, the touch sensing (RX) electrodes are usually set on the side of the Color Filter (CF) substrate away from the liquid crystal layer, and the TFT array The common (Common) electrodes on the inner side of the substrate are divided into multiple pieces as touch driving (TX) electrodes. In order to prevent the display driver and touch driver from interfering with each other, all TX signals are output at VCOM level during the display time; and during the touch scan period, each level of TX electrodes outputs N pulse signals, and the TX signals One row output, N is determined by the number of gate lines and the number of TX electrodes. [0003] figure 1 It is a sche...
