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 art, the current refresh frequency of the display panel is generally low, which makes the display panel prone to display defects such as flickering and afterimages, and increasing the refresh rate can help to improve the display defect. However, existing display panels have the problem that it is difficult to increase the refresh rate. The inventors found that the reason for the above problems is that when the refresh frequency of the display panel is low, each frame needs to ...

Abstract

An embodiment of the invention discloses a display panel and a driving method thereof.The display panel comprises m scanning circuits, in the m scanning circuits, the jth scanning circuit is electrically connected with the dm + jth scanning line in the second direction, and m is larger than or equal to 2; and the driving chip controls any one of the m scanning circuits to output a scanning pulse signal in each frame under the display mode of m times of basic refresh frequency, so that only 1 / m pixel circuits in the display panel perform writing of data signals and emit light in each frame under the display mode of m times of basic refresh frequency. According to the display panel, on the basis of not changing the bandwidth of the driving chip and ensuring the charging time of the capacitorin the pixel circuit, the refreshing frequency of the display panel can be improved, and the problems of flickering and ghosting of the display panel are further improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a driving method thereof. Background technique [0002] With the development of display technology, the requirements for display quality are getting higher and higher. [0003] The refresh rate of the display panel is different, and the display effect is usually different. Currently, the refresh frequency of the display panel is generally low, which makes the display panel prone to poor display phenomena such as flickering and afterimages. Increasing the refresh frequency can help to improve the poor display. [0004] However, existing display panels have the problem that it is difficult to increase the refresh rate. Contents of the invention [0005] The invention provides a display panel and a driving method thereof, so as to increase the refresh frequency of the display panel, improve the display defect of the display panel, ...
