Embodiment Construction

[0039] 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.

[0040] As mentioned in the background, the existing display panel has the problem of afterimage. The afterimage problem of the display panel will be described below. Existing display panels generally include a plurality of pixels, each pixel includes a pixel circuit and a light emitting element, the pixel circuit includes a driving transistor for driving the light emitting element to emit light, and the driving transistor generates a driving current to control the light emitting brightness of the light emitting el...

Abstract

The embodiment of the invention discloses a display panel, a display device and a driving method of the display panel. The display panel includes: a first pixel, the first pixel includes a first pixel circuit and a first light-emitting element, and the first pixel circuit is used to drive the first light-emitting element to emit light; wherein, the first light-emitting element The current working range includes a first range and a second range, the efficiency change in the second range is relatively stable compared with the efficiency change in the first range, and the current in the second range is greater than the current in the first range ; The first light-emitting element works in the second interval. Compared with the prior art, the embodiment of the present invention improves the afterimage problem of the display panel and improves the display effect of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel, a display device, and a method for driving the display panel. 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 elements, and the pixel circuits drive the light emitting elements to emit light for display. However, the existing display panel has an afterimage problem, which affects the display effect of the display panel. Contents of the invention [0003] Embodiments of the presen...
