Example Embodiment

[0026] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the structure related to the present invention.

[0027] As described in the background art, there is a problem of short-term image retention in existing display panels. For example, when light-emitting devices that originally displayed different gray levels in the display panel switch to the same gray level, the light-emitting brightness is different, resulting in poor display effects. According to the inventor’s research, the reason for the above problems is that the existing display panel usually includes a plurality of pixel circuits. The pixel circuit includes a driving transistor for driving the ligh...

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...
