Abstract
There is provided a method for driving a display device at low power. The method includes steps of: (a) a display power controller determining an allowable power value for driving the display device according to a predetermined condition; and (b) in case a present power value due to a driving of the display device is greater than the allowable power value, the display power controller performing at least one of (i) a 1-st driving current control sub-process of reducing a 1-st bias current supplied to a display panel of the display device to a 2-nd bias current corresponding to the allowable power value, (ii) a 2-nd driving current control sub-process of reducing an on-duty time of a PWM for driving LEDs of the display panel, and (iii) a 3-rd driving current control sub-process of performing at least one of BC and ACL which correspond to the video data.
