Abstract:
1. A backlight assembly comprising: a plurality of point-light sources; a substrate having comprising the plurality of point-light sources disposed thereon; and a power-controlling section providing the plurality of point light sources representing normal images with a first driving current having a first pulse current having first pulse duty cycles with first amplitudes, and providing the plurality of point-light sources representing a high luminance image with a second driving current having a second pulse current with a second pulse duty and a second amplitude, wherein the first pulse duty cycles are different from each other, and the first amplitudes are constant, so that the first pulse duty cycles represent the normal images different from each other, and the second pulse duty cycle is larger than or substantially equal to the first pulse duty cycles, and the second amplitude is larger than the first amplitudes, so that the second amplitude represents the high luminance image different from the normal images.
