ARRAY SUBSTRATE, DISPLAY DEVICE AND DRIVING METHOD THEREFOR

摘要

An array substrate, a display device and a driving method therefor. The array substrate comprises a plurality of gate lines (3) and a plurality of data lines (2). The plurality of gate lines (3) and the plurality of data lines (2) are arranged around a plurality of pixel units formed in an array arrangement. Each pixel unit comprises a common electrode (5) and a pixel electrode (6). At least a portion of the common electrodes (5) of the pixel units form touch driving electrodes. At least a portion of the plurality of data lines (2) form touch sensing electrodes. The touch driving electrodes and the touch sensing electrodes are insulated from each other. The touch driving electrodes are subject to a common voltage in a display phase, and to a touch scanning signal in a touch phase. The touch sensing electrodes are subject to a data signal in the display phase, and produce and output a coupling signal in the touch phase.
