Abstract
Array substrate, display panel and electronic device are provided. The array substrate includes: a touch control circuit including first switches, second switches and a first control module; and touch control electrodes arranged in array and insulated from one another, wherein adjacent touch corresponding control electrodes are connected with each other through first switch, each touch control electrode is connected with signal line through second switch, when the array substrate is in touch control detection state, the first control module turns off first switches connecting to touch control electrodes in a particular row, and turns on second switches connecting to touch control electrodes in the particular row, such that touch control electrodes in the particular row are disconnected from other ones and electrically connected to signal line; and repeat above processing row by row. Detection signal lines are saved, wiring is simplified, space for wiring is saved, and cost is reduced.
