Pixel circuit, driving method thereof and display device

Abstract

The embodiment of the invention discloses a pixel circuit, a driving method thereof and a display device. The pixel circuit comprises a data writing module, a first reset module, a driving transistorand a light emitting module, wherein the data writing module is used for writing a constant first voltage signal input by a data signal end into a first pole of the driving transistor in a first resetstage; the first reset module is used for writing a reset voltage signal input by a reset signal end into a grid electrode of the driving transistor in a first reset stage; and the data writing module is used for writing a data voltage signal input by the data signal end into the grid electrode of the driving transistor in a data writing stage. According to the technical scheme, complete reset ofthe driving transistor can be achieved, the ghost phenomenon is reduced, and the display effect is improved.

Description

technical field

[0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a pixel circuit, a driving method thereof, and a display device. Background technique

[0002] With the development of display technology, people have higher and higher requirements for display effects.

[0003] 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.

[0004] However, there is a problem of short-term afterimage in the existing display panel, which makes the display effect poor. Contents of the invention

[0005] The invention provides a pixel circuit, a driving method thereof, and a display device, so as to improve short-term afterimage phenomenon and improve display effect.

[0006] In the first aspect, an embodiment of the present invention provides a pixel circuit, and the pixel circuit includes a data wri...
