摘要： In a method for driving a light source, a backlight assembly for performing the method and a display apparatus having the backlight assembly, a light source is driven by an initial power until a first time when initial brightness of the light source decreases to a reference brightness. Then, the light source is driven by a first compensation power after the first time, so that the light source has first compensation brightness. When the brightness of the light source decreases to the reference brightness, a driving power applied to the light source is changed to compensate the brightness of the light source. Thus, the light source is driven to have uniform brightness over an extended length of time.

摘要： A plurality of point-light sources emits light, based on an image displayed on a display panel. A substrate has the point-light sources disposed thereon. A power-controlling section provides the point-light sources with first driving current having a pulse current with a pulse modulation duty less than or equal to a maximum pulse modulation duty cycle and a first amplitude in accordance with a normal image. A power-controlling section provides the point-light sources with second driving current having a pulse current with the maximum pulse modulation duty cycle and first boosting amplitude greater than the first amplitude in accordance with a high luminance image. Thus, the quantity of emitted light of the point-light sources may be adjusted in accordance with the position of an image displayed in a display panel, and the point-light sources that correspond to high luminance images may be boosted up.
