Abstract

The embodiment of the invention discloses a pixel circuit, a display panel and a driving method of the pixel circuit. The pixel circuit comprises a data writing module, a driving transistor, a storagemodule, a light-emitting control module, a light-emitting module, a first initialization module and a second initialization module. The first initialization module is connected between a first reference voltage input end and a grid electrode of the driving transistor. The first initialization module is used for initializing the grid electrode of the driving transistor under the control of a control signal input by the control end of the first initialization module. The second initialization module is connected between a second reference voltage input end and a first pole of the driving transistor. The second initialization module is used for initializing the first pole of the driving transistor under the control of an input signal of the control end of the second initialization module. The control ends of the first initialization module and the second initialization module are electrically connected with a first scanning signal input end. Compared with the prior art, the problem of ghosting is solved, and the display effect of the display panel is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a pixel circuit, a display panel, and a driving method for the pixel circuit. Background technique [0002] With the continuous development of display technology, the application range of display panels is becoming wider and wider, and people's requirements for display panels are also getting higher and higher. In particular, the display quality of a display panel has always been one of the important indicators for consumers and panel manufacturers to measure the quality of a display panel. Existing display panels usually include a plurality of pixel circuits and light emitting devices, and the pixel circuits drive the light emitting devices to emit light for display. However, the image sticking phenomenon exists in the existing display panel, which affects the display effect of the display panel. Contents of the invention [0003] Embodiments ...
