Array substrate and touch control display screen

Abstract

The invention provides an array substrate. The array substrate comprises multiple grid wires and touch control electrodes arranged in an array, wherein each touch control electrode comprises multiple sub electrodes, each sub electrode and the grid wires extend along a first direction, the multiple sub electrodes are arranged in a second direction at intervals, the first direction and the second direction are vertical to each other, the multiple sub electrodes are electrically connected through a first touch control lead wire, and projections of the grid wires on the touch control electrodes are disposed between two corresponding sub electrodes. According to the invention, the touch control electrodes are segmented into the multiple sub electrodes distributed at intervals, the projections of the grid wires on the touch control electrodes are disposed in the intervals between the sub electrodes, the touch control electrodes are enabled to avoid the grid wires, capacitance of the grid wires for the touch control electrodes is reduced, interference caused by other signals during touch control is reduced, the touch control sensitivity is improved, and the touch control response time is shortened. The touch control display screen has the advantages of high touch control sensitivity and short touch control response time.

Description

technical field [0001] The present invention relates to the technical field of touch display, and more specifically, to an array substrate and a touch display screen. Background technique [0002] With the development of self-capacitive touch display integration technology, the common electrode layer of the array substrate in the display panel can also be used as the touch electrode layer for self-capacitive touch detection, and the touch can be performed in time-sequence through time-sharing driving Control and display control can realize touch and display functions at the same time. In this way, the touch electrodes are directly integrated into the display panel, which greatly reduces the manufacturing cost, improves the production efficiency, and reduces the thickness of the panel. [0003] When the common electrodes are reused as touch electrodes, the common electrode layer needs to be divided into multiple independent common electrodes. At the same time, in order to r...

Problems solved by technology

However, in the existing self-capacitive touch display device, the coupling capacitance that is easily generated between the common electrode and the gate line increases the load on the touch electrode and reduces the touch sensitivity.
