Provided is a pixel circuit. The pixel circuit includes: a data writing circuit, coupled to a first gate signal terminal, a second gate signal terminal, a third gate signal terminal, a data signal terminal, a first node, a second node and a third node; a light emission control circuit, coupled to a light emission control terminal, a first power supply terminal, the first node, the third node and a light-emitting element; and a drive circuit, wherein an input terminal, a control terminal and an output terminal of the drive circuit are coupled to the first node, the second node and the third node respectively.

Pixel circuit and driving method thereof, and display device

A pixel circuitry, a pixel driving method and a display device are provided. The pixel circuitry includes a first light-emission control circuitry, a driving circuitry, a second light-emission control circuitry, a resetting control circuitry and a light-emitting element. The resetting control circuitry is electrically connected to a resetting control line, a connection node and a first initial voltage end for providing a first initial voltage, and configured to apply the first initial voltage to the connection node under the control of a resetting control signal from the resetting control line. The connection node is a first node, a third node or a fourth node. According to the present disclosure, it is able to suppress the occurrence of flicker.

Pixel circuitry, pixel driving method and display device

A display panel includes multiple pixel units that are arranged regularly. A pixel circuit is connected with a scanning signal line and a data signal line. The pixel circuit receives a data voltage transmitted by the data signal line and outputs a corresponding current to a light emitting device under a control of the scanning signal line. When a first light emitting unit is in a black state, the data signal line provides a reference black state voltage to a pixel circuit of the first light emitting unit. The driving method of the display panel includes: providing, by the data signal line, a first black state voltage to a pixel circuit of a second light emitting unit when the first light emitting unit emits light and the second light emitting unit is in the black state. The first black state voltage is less than the reference black state voltage.
