Abstract

The invention discloses a display panel and a driving method. A pixel driving circuit comprises a driving transistor, at least two data writing modules and a light emitting control module, the data writing modules are used for providing data signals for the driving transistor in a time-sharing manner; the light emitting control module is connected with the driving transistor and a light emitting element in series and used for controlling whether driving current flows through the light emitting element or not. According to the embodiment of the invention, the flicker problem caused by insufficient charging of the driving transistor of the pixel driving circuit can be solved.

Description

technical field [0001] The present invention relates to the field of display panels, in particular to a display panel and a driving method. Background technique [0002] Organic light-emitting display devices have the advantages of self-luminescence, low driving voltage, high luminous efficiency, fast response speed, thinness, and high contrast, and are considered to be the most promising display devices for the next generation. [0003] A pixel in an organic light emitting display device includes a pixel driving circuit. The driving transistor in the pixel driving circuit can generate a driving current, and the light emitting element emits light in response to the driving current. However, due to the limitation of the scanning pulse width of the gate drive circuit, the data writing phase of the pixel drive circuit is too short, resulting in insufficient charging of the gate of the drive transistor of the pixel drive circuit, resulting in a large luminous brightness in the ...
