Abstract
The present invention provides a light source control module, a backlight module and driving method thereof which can overcome the problems of insufficient color amount, poor performance and lowered color saturation. A light source control module of the present invention is used for separately controlling illumination colors and/or brightness of each light source in the backlight module according to image information. The driving method of the backlight module comprises: calculating representative color and/or brightness of each image section based on image information, wherein each image section corresponds to a light output area on the output surface of the backlight module, each light output area is illuminated by one light source in the backlight module; adjusting the illumination colors and/or brightness of each light source such that the color and/or brightness of each light output area is in conformity with the representative color and/or brightness of corresponding image section.
