Abstract
A display device is provided. The display device includes a display panel, a scaler integrated circuit, and a backlight device. The backlight device includes N light zones for providing a backlight to the display panel, wherein N is a positive integer. The backlight device lights each of the N light zones in a time-sharing manner in each of a plurality of scan periods. Each of the scan periods has a time length greater than or equal to a time length of a video active data period of the display panel. A continuous lighting time length of each of the N light zones is less than or equal to a quotient of the time length of the video active data period divided by N.
