Embodiment Construction

[0017] In the existing display panel, each pixel electrode needs to be driven sequentially, so that the driving power consumption of the display panel is relatively high. Moreover, during the display process of the display panel, such a display situation often occurs: in the entire pixel area, except for a few areas displaying dynamic images, most areas display static images (or pictures) that do not change. Since the existing display panel does not distinguish between the area displaying dynamic images and the area displaying static images, they all adopt the same driving mode (usually dynamic driving mode) for driving. It can be seen that the existing method adopts a single driving mode, resulting in unnecessary increase of driving power consumption.

[0018] In order to prevent the occurrence of the above situation, the present invention provides a new display panel, which includes a plurality of sub-pixel regions, and each sub-pixel region adopts a different driving mode a...

Abstract

Disclosed are a display panel and a driving method thereof. The display panel comprises a plurality of sub-pixel areas and a plurality of sub-grid driving circuits. Every sub-pixel area is driven by the corresponding sub-grid driving circuit; every sub-grid driving circuit comprises at least one initial scanning signal end. The driving method comprises dividing the display panel into the plurality of sub-pixel areas, and determining whether every sub-pixel area corresponds to a static image or a dynamic image; when the sub-pixel area corresponds to the dynamic image, driving the sub-pixel area in a dynamic driving mode; when the sub-pixel area corresponds to the static image, driving the sub-pixel area in a static driving mode. The display panel and the driving method thereof can reduce driving power consumption.

Description

technical field [0001] The invention relates to the field of optoelectronic display, in particular to a display panel and a driving method thereof. Background technique [0002] Display panels have been used in many electronic products. At present, whether it is a liquid crystal display panel, an organic light-emitting display panel or an electronic paper display panel, most of them are driven by an active matrix driving method. Correspondingly, a display panel using an active matrix needs to match an active matrix driving circuit. The driving circuit usually includes a gate driving circuit. [0003] In the prior art, a display panel includes a plurality of pixel electrodes, a plurality of gate lines, a plurality of data lines and a plurality of switching devices, and the pixel electrodes in the same row are connected to a gate line through respective switching devices, located The pixel electrodes of the columns are connected to a data line through respective switching d...
