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: The present invention teaches a direct-lit backlight module and a related manufacturing method. The direct-lit backlight module includes a driver substrate, a reflection layer on the driver substrate, multiple mini-LEDs arranged in an array on the reflection layer, multiple reflection bumps on the reflection layer among the mini-LEDs, and an optical film set on the reflection layer, the mini-LEDs, and the reflection bumps. The mini-LEDs are electrically connected to the driver substrate. The reflection bumps jointly form a mesh dot structure. When light passes through the mesh dot structure, the light is scattered by the mesh dot structure to various directions, thereby enhancing the lighting efficiency of the direct-lit backlight module.
