  • Publication number: 20230237972
    Abstract: A display method of a display panel, a display device, and a server are disclosed. The display method divides an initial image into a plurality of sub-frame images having a same frequency, and the frequency of the sub-frame images is a multiple of a frequency of the initial image. The sub-frame images are input into the display panel in sequence and are combined to obtain a target image. The target image is used to drive the display panel to display the initial image, thereby reducing a refresh rate of the display panel for inputting data. Therefore, the display panel can realize low frequency input and prevent frame loss.
