Abstract: Disclosed is a backlight diffusion parameter generation method, including: selecting and measuring illumination diffusion data of at least one light emitting region in a plurality of light emitting regions, the illumination diffusion data includes brightness data of a plurality of pixels on a display panel and distance data between positions corresponding to the plurality of pixels and a position where an illuminated light emitting region is located when only one of the light emitting regions is illuminated; preprocessing the illumination diffusion data to obtain an effective pixel; performing function fitting according to data corresponding to a plurality of effective pixels to obtain a point spread function representing a relationship between diffusion brightness and a diffusion distance; and storing a backlight diffusion parameter lookup table, which includes a plurality of sub-tables, each sub-table corresponds to one or more light emitting regions affected when only one light emitting region is illuminated.

Abstract: A liquid crystal display device, a method for displaying an image, and an electronic device are provided. In the first operation mode, a control circuit of the display device is configured to: receive display data of an mth image frame, and control the display device to display n sub-field images. The display data includes initial gray scales under n base colors. In a sub-field image of the mth image frame: pixels include a target pixel, and an actual gray scale of the target pixel is an average of an intermediate gray scale and initial gray scales of T non-target pixels. An actual gray scale of at least a part of non-target pixels is an initial gray scale thereof. The target pixel meets at least one of a first condition and a second condition.

Abstract: Disclosed is a backlight diffusion parameter generation method, including: selecting and measuring illumination diffusion data of at least one of multiple light emitting regions, wherein the illumination diffusion data includes brightness data of multiple pixels on a display panel and distance data between positions corresponding to multiple pixels and a position where an illuminated light emitting region is located when only one light emitting region is illuminated; preprocessing the illumination diffusion data to obtain an effective pixel; performing function fitting according to data corresponding to multiple effective pixels to obtain a point spread function representing a relationship between diffusion brightness and a diffusion distance; storing a backlight diffusion parameter lookup table, which includes multiple diffusion distance bonding points and diffusion brightness corresponding to each of the diffusion distance bonding points, and also includes a diffusion slope between two adjacent diffusion distance bonding points.
