Dynamic Backlight Adaptation Based on the Details of Image for Liquid Crystal Displays

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.
