Problems solved by technology

[0002] In the prior art, in order to realize the touch function, touch driving electrodes need to be provided in the display device. However, the touch driving circuit for providing touch driving signals to the touch driving electrodes is relatively complicated, which makes it difficult for the corresponding display device to realize narrow frame
In addition, since the touch driving circuit has more signal input terminals, the touch driving circuit needs more output signals from an integrated control circuit (Integrated Circuit, IC for short), thereby increasing the cost of the IC.

Abstract

The invention relates to an array substrate, a touch display device, and a driving method thereof. The array substrate includes a display region and a peripheral region surrounding the display region. The display region includes N rows of scanning lines, wherein N is a positive integer more than 1. The peripheral region includes a touch driving circuit and a gate driving circuit, wherein, the touch driving circuit includes M stages of touch output units for generating touch driving signals, where M is an integer more than 0 and less than or equal to N; the gate driving circuit includes N stages of shift registers for said N rows of scanning lines which generate scanning signals. The M stages of shift registers include a first strobe signal output terminal and a second strobe signal output terminal, which provide a first strobe signal and a second strobe signal for the M stages of touch output units, respectively; the touch output unit includes PMOS tubes from the first one to the eleventh one. The invention uses the signal in the shift register as the input strobe signal of the touch driving circuit to realize narrow border.

Description

technical field [0001] The present invention generally relates to the field of display technology, and in particular, relates to an array substrate, a touch display device and a driving method thereof. Background technique [0002] In the prior art, in order to realize the touch function, touch driving electrodes need to be provided in the display device. However, the touch driving circuit for providing touch driving signals to the touch driving electrodes is relatively complicated, which makes it difficult for the corresponding display device to realize narrow frame. In addition, since the touch driving circuit has more signal input terminals, the touch driving circuit needs more output signals from an integrated control circuit (Integrated Circuit, IC for short), thereby increasing the cost of the IC. [0003] Therefore, a new array substrate and a touch display device are needed to solve the above problems. [0004] The above information disclosed in this Background sec...
