摘要：
Disclosed are a method and a device for controlling brightness of a display device, and a liquid crystal display. In the method, a saturation signal and an area dimming signal of each of partitioned screens of the display panel are acquired, and a saturation dimming signal of each of partitioned screens of the display panel is calculated according to the saturation signal, for adjusting the backlight brightness.
