Abstract

The invention provides a pixel circuit, a driving method thereof and a display panel. The pixel circuit includes: a light emitting element; a driving sub-circuit configured to generate a current for causing the light emitting element to emit light; a first light-emitting control sub-circuit and the second light-emitting control sub-circuit, respectively configured to supply current for enabling the light-emitting element to emit light to the first end of the light-emitting element under the control of a first control signal; a driving control sub-circuit, configured to provide the data voltagesignal to the driving sub-circuit under the control of the second control signal; and a reset sub-circuit, configured to use the second voltage to reset the driving sub-circuit, the first end of thelight-emitting element and the second node under the control of the first reset signal and the second reset signal.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a pixel circuit, a driving method thereof, and a display panel. Background technique [0002] In an OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display device, due to the hysteresis effect of the driving transistor, afterimages may occur. Conventional methods attempt to improve the afterimage effect by changing the modulus and thickness of the gate insulating layer, the doping amount of the polysilicon layer, and the interface quality between the two layers, but the effect is not significant. Contents of the invention [0003] The disclosure proposes a pixel circuit, a driving method thereof, and a display panel. [0004] According to one aspect of the present disclosure, a pixel circuit is provided. The pixel circuit includes: a light emitting element; a driving subcircuit configured to generate current for making the light emitting elemen...
