Abstract

The invention provides an array substrate, a touch display panel and a touch display device. The array substrate comprises grid lines, data lines, pixel units and a public electrode layer, wherein the pixel units are enclosed by the grid lines and the data lines, and the public electrode layer is divided into multiple electrode units. Each electrode unit comprises at least two electrode blocks provided with nested intersection areas, the length of the intersection area in the extending direction of the data lines is larger than or equal to the length of an overlapped area of driving signals along the extending direction of the data lines, and the overlapped area of the driving signals comprises the overlapped grid lines and pixel units electrically connected with the grid lines. Accordingly, coupling mutation degree at the boundary of the adjacent electrode blocks can be lowered, voltage change amplitude of the electrode blocks during cutoff of thin-film transistors of the pixel units of the adjacent electrode block boundary is alleviated, and image display effect is improved.

Description

technical field [0001] The present invention relates to the field of touch technology, and more specifically, to an array substrate, a touch display panel and a touch display device. Background technique [0002] With the development of integrated touch and display technology, the common electrodes of the array substrate of the display panel can be reused as touch electrodes, and time-sequential touch driving and display driving can be performed in a time-sharing manner, so as to simultaneously realize touch and display. Display function. 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] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an array substrate for a touch display panel, the array substrate includes: a plurality of gate lines 11, a plurality of data lines 12 and a common elec...
