Abstract
A display panel and a driving method are provided. The pixel driver circuit includes a drive transistor, at least two data write modules, and a light emission control module. The at least two data write modules are configured to provide data signals for the drive transistor in a time-sharing manner, and the light emission control module is connected in series respectively with the drive transistor and the light-emitting element and is configured to control whether a drive current flows through the light-emitting element.
Claims20
A display panel, comprising:
- a plurality of sub-pixels arranged in an array;
- each of the plurality of sub-pixels comprising a light-emitting element;
- and a pixel driver circuit,
- the pixel driver circuit having a drive transistor, at least two data write modules, and a light emission control module, the at least two data write modules being configured to provide data signals for the drive transistor in a time-sharing manner,
- the light emission control module being connected in series respectively with the drive transistor and the light-emitting element, and the light emission control module being configured to control whether a drive current flows through the light-emitting element.
The driving method of claim 21, wherein the pixel driver circuit further comprises a first reset module, and the drive period of the display panel further comprises an initialization stage;
- and wherein the driving method further comprises:
- in the initialization stage before the data write stage, resetting, by the first reset module, a control terminal of the drive transistor;
- wherein the pixel driver circuit further comprises a second reset module, and the second reset module is electrically connected to the light-emitting element;
- and wherein the method further comprises:
- in at least part of a time period in other stages except for the light emission stage, resetting, by the second reset module, the light-emitting element.
