Abstract
An array substrate, a display device, and a drive-for-heating method for the display device. The array substrate includes: pixel units on a first base substrate; a data line on the first base substrate; a touch signal line on the first base substrate; a heating element on the first base substrate, and configured to generate heat under driving of a drive-for-heating current; a common electrode on the first base substrate and reused as a touch electrode; and a pixel electrode on the first base substrate. The thin film transistor includes an active layer in a semiconductor layer and a gate electrode in a first conductive layer. The data line is in a second conductive layer, one of the pixel electrode and the common electrode is in a third conductive layer, and a layer where the heating element is located is between the semiconductor layer and the third conductive layer.
