The invention discloses an array substrate, an array substrate manufacturing method and a display panel comprising the array substrate. The array substrate comprises a substrate body, a pixel electrode array arranged on the substrate body and composed of a first conductor layer, a second conductor layer arranged on the first conductor layer, and a first metal layer arranged on the first conductor layer, wherein the pixel electrode array comprises a plurality of pixel electrodes corresponding to one sub-pixel area, the second conductor layer comprises a plurality of strip-shaped common electrodes arranged in the first direction, and the strip-shaped common electrodes extend in the second direction and are used for providing common voltage for the sub-pixel area in the display stage; the first metal layer comprises a plurality of first metal conductors and a plurality of second metal conductors, and the first metal conductors electrically connected with the same common electrode are connected through at least one second metal conductor. By the adoption of the scheme, the resistance of the common electrodes can be reduced, and then signal delay of the common electrodes can be improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a touch display device including the array substrate. Background technique [0002] Capacitive touch screens can be divided into surface capacitive touch screens and projected touch screens according to their touch principles. The projected touch screen can be further divided into a self-capacitive touch screen and a mutual-capacitive touch screen. [0003] A mutual capacitive touch screen includes touch driving electrodes and touch sensing electrodes. The touch driving electrodes are connected to the touch scanning lines to receive touch scanning signals sent by the driving chip. The touch sensing electrodes transmit the sensed touch signals to the touch chip, so as to determine the touched position. [0004] Generally speaking, the touch driving electrodes of the mutual capacitive touch screen are multiplexed a...
