Abstract: Disclosed are an array substrate and a driving method, a display panel and a touch display device. The array substrate includes: electrode column groups each including M adjacent electrode columns; touch signal lines each including a first signal line and a second signal line electrically connected to each other; M common voltage lines, M first switch control lines and first switch device groups; and M second switch control lines, second switch device groups and touch signal terminal groups. Each second switch device group includes M sub-switch device groups, each of which includes N second switch devices, and each touch signal terminal group includes N touch signal terminals. N touch signal terminals in the same touch signal terminal group are respectively electrically connected to the second terminals of N second switch devices in any sub-switch device group in the same second switch device group in a one-to-one manner.
