Abstract

Embodiments of the present invention disclose a display panel, a driving method and a display device. The display panel includes a gating circuit, a pixel driving circuit and a light-emitting element; the pixel driving circuit includes a first initialization unit, a driving module and a first light-emitting control unit; the gating circuit is electrically connected with the initialization signal terminal; the first initialization unit is electrically connected Between the initialization signal terminal and the anode of the light-emitting element; in the write frame, the first initialization unit is used to provide the first initialization voltage signal Vref1 to the anode of the light-emitting element under the control of the first scan signal; in the hold frame, the first initialization voltage signal Vref1 The initialization unit is used for providing a second initialization voltage signal Vref2 to the anode of the light-emitting element under the control of the first scan signal. The technical solutions provided by the embodiments of the present invention can reduce the brightness difference between the write frame and the hold frame, and improve the flicker problem.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a driving method, and a display device. Background technique [0002] With the development of display technology, organic light-emitting display panels have become mainstream display panels due to their advantages such as low power consumption and fast response speed, and are widely used in electronic devices such as mobile phones, notebooks, and computers. [0003] How to reduce power consumption has always been a major research hotspot in the display field, and various methods for reducing power consumption have emerged. Among them, in some cases, the way of reducing the driving frequency is effective in reducing power consumption. significantly. Specifically, the display panel includes a normal driving mode and a low-frequency driving mode. When displaying a dynamic picture, the normal driving mode can be used, and the driving freq...
