Abstract

A backlight control device for controlling a driving current of an LED is disclosed. By controlling current outputs from current sources of a plurality of current output units, a display will be able to generate desirable backlight. Then by adjusting currents output by the plurality of current output units, brightness of a plurality of pixels can be dynamically adjusted. The brightness of pixels with higher gray levels can be increased while the brightness of pixels with lower gray levels can be decreased, thereby improving the contrast of image and saving power consumption.
