ARRAY SUBSTRATE AND DRIVING METHOD THEREOF, DISPLAY PANEL AND DISPLAY DEVICE

摘要

An array substrate and a driving method thereof, a display panel and a display device. The array substrate includes a plurality of areas. Each area at least includes a first subpixel and a second subpixel, and each subpixel includes a corresponding display unit; the first subpixel includes a photosensitive identification unit, the photosensitive identification unit is connected with a read signal line and is configured to acquire and store position information of a touch position and transmit the acquired position information to the read signal line; and the second subpixel includes a capacitive detection unit, the capacitive detection unit is connected with the read signal line and is configured to acquire information of a touch object and transmit the acquired information of the touch object to the read signal line. The display device has a function of touch object identification (e.g., palm print identification) and has a simple structure.
