Array substrate, manufacturing method thereof and touch display device
An array substrate, a manufacturing method thereof, and a touch display device are provided in the embodiments of the present invention. The array substrate includes: a common electrode layer including a plurality of self-capacitance electrodes distributed in an array; a drive circuit; and a plurality of pixel units distributed in an array. N self-capacitance electrodes located in a same column constitute an electrode column, each electrode column corresponding to M columns of pixel units. The N self-capacitance electrodes located in the same column are connected with the drive circuit via N touch leads arranged within different columns of pixel units. Among the M columns of pixel units, M−N columns of pixel units provided with no touch leads are provided with dummy leads connected with the drive circuit, and the drive circuit is used to input a common voltage signal into the dummy leads and the touch leads.
