Abstract
A pixel circuit includes a sensing circuit, a gray-scale control circuit and a light-emitting switch circuit; the sensing circuit is configured to charge and discharge a sensing capacitor when a sensing capacitor is formed by a touch object and an anode layer of OLED; the gray-scale control circuit is configured to control the light-emitting intensity of the OLED; the light-emitting switch circuit is configured to control the OLED to emit light.
