Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should 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 the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0046] As mentioned in the background art, there is an image sticking problem in the display panel. After research, the inventors found that the cause of the image sticking phenomenon is the hysteresis effect of the driving transistor. figure 1 It is a schematic diagram of a current-voltage curve of an existing driving transistor. see figure 1, the curve 13 is the curve of the current Ids between the source and the drain during the gradual increase of the voltage Vgs between the gate and the source of the driving...

Abstract

The invention provides a display panel, a display device and a driving method of the display panel. The display panel comprises at least one pixel circuit group. The pixel circuit group comprises an output switching unit, a first pixel driving circuit and a second pixel driving circuit. The output switching unit comprises a first output signal end, a second output signal end, a first input signalend and a second input signal end. The first pixel driving circuit is electrically connected with the first input signal end, and the second pixel driving circuit is electrically connected with the second input signal end. The light-emitting device comprises a first light-emitting device and a second light-emitting device, the first light-emitting device is electrically connected with the first output signal end, and the second light-emitting device is electrically connected with the second output signal end. The output switching unit controls the pixel driving circuits in the pixel circuit group to drive different light emitting devices in the first stage and the second stage. According to the display panel, the display device and the driving method of the display panel, the ghost shadowphenomenon of the display panel is reduced, and the display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a driving method for the display panel. Background technique [0002] With the development of display technology, display panels have played an increasingly important role in people's lives, and the corresponding requirements for display technology have also become higher and higher. [0003] However, the existing display panel is prone to image sticking when the screen is switched, which seriously affects the display effect. Contents of the invention [0004] The invention provides a display panel, a display device and a driving method of the display panel, so as to reduce the afterimage phenomenon of the display panel and improve the display effect. [0005] In a first aspect, an embodiment of the present invention provides a display panel, which includes: [0006] At least one pixel circuit group, the pixel circuit group inclu...
