We present an algorithm for efficient calculation of local dimming RGB LED-Backlight to save power consumption. The algorithm was implemented in hardware to support Full-HD resolution at a low HWcost. It showed clipping-free and video-capable results.

A contrast enhancement extension named as LSF Correlator has been amended to our Sorted Sector Covering (SSC) algorithm for the calculation of the LED duty‐cycles of a local dimming LED backlight. As a result, the static contrast of the display is significantly increased. The LSF Correlator has been proved on an 8″ WVGA prototype with an edge‐lit backlight.
