Embodiment Construction

[0066] 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.

[0067] As mentioned in the background, existing display panels have image sticking problems. The afterimage problem of the display panel will be described below. figure 1 It is a schematic diagram of the afterimage phenomenon of the conventional display panel. see figure 1 , when detecting the afterimage of the display panel, the display panel is firstly controlled to display a checkerboard picture (for example, the black block of gray scale 0 and the white block interval of 255 gray scale), and then the display...

Abstract

An embodiment of the invention discloses a pixel circuit, a display panel and a driving method of the pixel circuit. The pixel circuit comprises a first light-emitting control module and a gate initialization module, wherein the first light-emitting control module comprises a control end, a first end and a second end, a first light-emitting control signal is accessed to the control end of the first light-emitting control module, a first power supply signal is accessed to the first end of the first light-emitting control module, and the second end of the first light-emitting control module is electrically connected with a first electrode of a driving transistor; and the gate initialization module comprises the control end, a first end and a second end, an initialization control signal is accessed to the control end of the grid initialization module, and an initialization voltage signal is accessed to the first end of the grid initialization module. 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 ...
