Abstract

The invention provides a display control method and a preparation method of a display panel and a display device. The display panel comprises a backlight module and a display module located on the light emitting side of the backlight module, the backlight module comprises a plurality of subareas, and each subarea is provided with at least one light source; the display panel is provided with a plurality of sub-pixels; and each partition is corresponding to one or more sub-pixels. The display control method comprises the following steps: acquiring a brightness diffusion coefficient of a partition of the backlight module; for each sub-pixel, determining the display brightness of the sub-pixel according to the gray-scale value of the sub-pixel, the brightness diffusion coefficient and the gamma value of the display panel; and determining the brightness of each partition of the backlight module according to the original image data, controlling each partition to emit light according to the corresponding brightness, and controlling each sub-pixel to display at the corresponding display brightness.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display control method and preparation method of a display panel, and a display device. Background technique [0002] The backlight module of the Mini LED display device includes multiple partitions, each partition is equipped with one or more lamp beads, and the lamp beads in different partitions can be controlled independently. [0003] Mini LED display devices have halo phenomenon when displaying, especially when the display device is performing HDR (high dynamic range) display, the halo phenomenon is more obvious, which affects the display effect of the display device and the user experience. Contents of the invention [0004] According to the first aspect of the embodiments of the present application, a display control method of a display panel is provided. The display panel includes a backlight module and a display module located on the light-emitting side o...
