Embodiment Construction

[0026] 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.

[0027] As mentioned in the background technology, the existing display panel has the problem of image sticking during the display process. After careful research, the inventors found that the reason for the image sticking is that, for the driving transistor in the pixel circuit, due to the hysteresis effect of the transistor, When the driving transistor is in the biased state for a long time, multiple pixel circuits may need to display different images. For example, some pixel circuits need to be driven to display ...

Abstract

The invention discloses a driving method and a display device of a display panel. The driving method includes: in a first initialization stage, providing a first gate signal to the first gate line, and turning on the second transistor; providing a second gate signal to the second gate line, and The fourth transistor and the fifth transistor are turned on; in the data writing phase, a third strobe signal is provided to the third strobe line, and the third transistor is turned on; The gate line provides a first shutdown signal, the second transistor is turned off; a second gate signal is provided to the fourth transistor and the fifth transistor, and the fourth transistor and the fifth transistor are turned on . The embodiments of the present invention can improve the display unevenness problem of the display panel and improve the display uniformity.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a driving method and a display device for a display panel. Background technique [0002] With the development of display technology, the application of display panels is becoming more and more extensive, which further increases the requirements for display technology. [0003] However, existing display panels, such as OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panels, have problems such as display unevenness during the display process, resulting in poor display effects. Contents of the invention [0004] The invention provides a method for driving a display panel and a display device, so as to improve the display unevenness of the display panel and improve display uniformity. [0005] In a first aspect, an embodiment of the present invention provides a method for driving a display panel, the display panel includes a pixel circuit...
