摘要： A regional dimming driving method for a display device is provided. The display device includes multiple backlight sources respectively corresponding to multiple display regions of the display device. The regional dimming driving method includes acquiring a brightness value of each display region according to input image data, processing and adjusting the brightness value of each display region to acquire an adjusted brightness value of regional dimming of each display region, and respectively driving the backlight sources according to the adjusted brightness values of regional dimming of the corresponding display regions. By processing and adjusting the brightness values of the display regions, display effects can be effectively provided.
