Abstract
In conventional liquid crystal display (LCDs), the backlight is set
to maximum luminance regardless of the image which causes power waste and
light leakage in the dark scenes. To circumvent these problems, the local
dimming backlight is investigated. The algorithm based on details of the input
image for the local dimming backlight in LCDs is proposed in this paper. Experimental
results show that the proposed method achieves low power consumption and little
image distortion ratio simultaneously.
