Abstract

Provided are a method for controlling backlight of a display device, a backlight controller for a display device, and a display device. The method includes: identifying a light emission luminance of each backlight partition in a backlight module according to display luminances of the plurality of display partitions; when the plurality of backlight partitions include two adjacent backlight partitions and an absolute value of a difference between the light emission luminance of the two adjacent backlight partitions is greater than a target threshold, adjusting the light emission luminance of at least one of the two adjacent backlight partitions such that the absolute value of the difference between the light emission luminances of the two adjacent backlight partitions is decreased; and after the luminance is adjusted, controlling light-emitting of each backlight partition.
