Display panel, driving method thereof and display device

Abstract

The embodiment of the invention discloses a display panel, a driving method thereof and a display device. The display panel comprises a gate driving circuit, an initial signal line and n clock signallines, and n is greater than or equal to 3. The gate driving circuit comprises a plurality of cascaded shift registers. The output end of each shift register is at least electrically connected with one scanning line, wherein the first clock signal input end of the (kn + i)-th shift register is electrically connected with the i-th clock signal line, the second clock input end of the (kn + i)-th shift register is electrically connected with the (i + 1)-th clock signal line, k is greater than or equal to 0, and i is greater than or equal to 1 and less than or equal to n-1; the first clock signalinput end of the (m * n)-th shift register is electrically connected with the n-th clock signal line, and the second clock signal input end of the (m * n)-th shift register is electrically connected with the (m-1) n + 1 clock signal lines. According to the technical scheme, the data writing time of the pixel circuits in the upper and lower regions of the display panel tends to be consistent, and then the brightness difference of the upper and lower regions of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a driving method thereof, and a display device. Background technique [0002] With the development of display technology, high refresh rate display has become a major development trend. [0003] When the existing display panel is working, the refresh rate for displaying static images and dynamic game images is usually different. Specifically, the refresh rate for displaying static images is usually low, such as usually 60 Hz, while the refresh rate for displaying dynamic game images is usually higher. , such as 90Hz, 120Hz or 144Hz. [0004] However, existing display panels have the problem of inconsistency in the brightness of the upper and lower areas of the display panel at a higher refresh rate, especially when switching from a low refresh rate to a high refresh rate, the brightness difference between the upper and lower areas is ...
