Abstract
An array substrate includes a display area, an edge area, data lines, pixel units, a feedback transmission line, a feedback control circuit, and a display drive circuit. The edge area surrounds the display area. The feedback transmission line, the feedback control circuit, and the display drive circuit are spatially corresponding to the edge area. The feedback transmission line electrically connects at least one of the data lines and the feedback control circuit. The feedback transmission line detects a data signal transmitted by the data lines and outputs a feedback signal to the feedback control circuit. The feedback control circuit outputs a common voltage to the display drive circuit according to the feedback signal. The display drive circuit outputs the common voltage to the pixel units.
