Abstract
A display device has a backlight module with a plurality of light-emitting units. The light-emitting units are divided into a plurality of groups, and each group constitutes a lighting region. A backlight compensation method includes performing a local dimming process according to a gamma value of a display device by a backlight module; obtaining an area peak luminance of each lighting area; selecting one of the lighting regions as a selected region; obtaining a regional average luminance value based on the area peak luminance of the selected region and the area peak luminance of other lighting regions adjacent to the selected region; obtaining a luminance adjustment ratio based on a partial peak ratio corresponding to the regional average luminance value; obtaining a compensation luminance value based on the luminance peak value and the luminance adjustment ratio; and adjusting the luminance of the selected region based on the compensation luminance value.
