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.

Abstract: A plug-in touch display device includes a capacitive touch screen stacked on a display module. The display module includes a display panel and a backlight module that are supported in a middle frame. The display panel includes an array substrate that includes a pixel electrode, which also serves as a first capacitive sensing electrode. The middle frame has one side facing the backlight module and receiving a second capacitive sensing electrode arranged therein. A gap exists between the second capacitive sensing electrode and backlight module. The first capacitive sensing electrode and the second capacitive sensing electrode configure an electrode-induction device jointly, for sensing a pressure signal applied on the capacitive touch screen. In a display time period of one frame, the pixel electrode transmits pixel voltage signals and pressure sensing signals alternately.
