Abstract

The application discloses a driving method and device of a display panel, and a display device, which belong to the field of display technology. The display panel includes multiple groups of pixels, each group of pixels includes multiple rows of pixels arranged at intervals, and the multiple rows of pixels included in any two groups of pixels are arranged in a staggered manner, and the method includes: according to the received low-frequency display instruction, displaying specified When displaying an image, sequentially control each group of pixels in the plurality of groups of pixels to be turned on row by row, and during the process of each group of pixels being turned on row by row, input the pixels corresponding to the specified image to each column of pixels in the display panel. Data signal; after each group of pixels is turned on, before the next group of pixels is turned on, stop inputting the data signal to the pixels of each column; wherein, the time difference between the turn-on moments of two adjacent groups of pixels is the multiple groups The amount of time it takes pixels to turn on row by row. The method provided by the present application can avoid flickering of the display screen when reducing the refresh frequency of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method and device for driving a display panel, and a display device. Background technique [0002] The refresh rate of the display panel refers to the frequency at which the display panel updates the display images. Currently, the refresh frequency of the display panel is generally 60 Hz (hertz), that is, the display images of the display panel are updated 60 times per second. In order to reduce the driving power consumption of the display panel, when the display panel displays a static picture, its refresh rate can be reduced. [0003] In related technologies, a frame skip method is generally used to reduce the refresh rate of the display panel. Specifically, when the display panel displays odd-numbered frame images, the source driver chip can normally output data signals to charge the pixel electrodes of each column of pixels in the display panel; when the display p...
