Title: PIXEL CIRCUIT, PIXEL DRIVE METHOD AND DISPLAY DEVICE
Abstract:
A pixel circuit, a pixel drive method and a display device, which fall within the technical field of displays and can solve the problem that a short circuit between the cathode and anode of existing OLED pixels affects the peripheral pixels and thus affects the display quality. A short circuit control unit (3) in a pixel circuit is connected between a light-emitting device (1) and a light-emission control unit (4), and is used for acquiring an input end signal of the light-emitting device (1) and outputting a short circuit control signal according to the input end signal of the light-emitting device (1); and the light-emission control unit (4) is connected to the short circuit control unit (3) and is connected in series between a drive unit (2) and the light-emitting device (1), and is used for controlling the ON/OFF of a connection branch between the drive unit (2) and the light-emitting device (1) according to the short circuit control signal. Compared to a laser ablation method, this pixel circuit is simple and easy to control without further adding a laser ablation device.
