Array substrate, touch display panel and touch display device
One inventive aspect is an array substrate, which includes a plurality of touch leads, a common electrode layer, and a drive circuit. The common electrode layer is divided into a plurality of columns of self-capacitive electrodes, which are electronically connected to the drive circuit through the touch leads. The array substrate also includes a plurality of pixel units. Each touch lead is electronically connected to the self-capacitive electrode corresponding to the touch lead via a first via hole. At least one touch lead is parallel to and cross over one column of the self-capacitive electrodes. In a direction perpendicular to the array substrate, a projection of the self-capacitive electrode covers projections of a plurality of pixel units. In addition, along a direction of the touch leads, an interval between two adjacent first via holes is greater than or equal to a length of two pixel units.
