Pixel circuit, driving method of pixel circuit, and display panel

Abstract

The application discloses a pixel circuit, a driving method of the pixel circuit and a display panel. The pixel circuit comprises a driving module, a data writing module, a coupling module, a first potential control module, a second potential control module, an off control module and a light-emitting module. The first end of the coupling module is connected with a sweep signal. The second end of the coupling module is connected with the off control module and the second potential control module. The data writing module is used for transmitting a data voltage to the second end of the coupling module. The second potential control module is used for controlling the potential of the control end of the driving module according to the data voltage and the sweep signal, so as to control the light-emitting time length of the light-emitting module. The off control module is used for controlling the on-off state of the first potential control module according to the data voltage and the sweep signal, so that the first potential control module is turned off when the second potential control module is turned on. The technical scheme provided by the application can shorten the intermediate state of the driving module, so as to improve the uniformity of picture display.
