48.4: Invited Paper: Adaptive Luminance and Power Control (ALPC) for LED Backlight Units

Adaptive luminance and power control is proposed for LCD‐TVs with LED backlight units to provide several advanced features compared to conventional local dimming LED backlights. with ALPC, the luminance of a bright image on the display increases as the size of the bright image decreases, resulting in higher image quality that is more comfortable to end users. A 46” FHD LCD‐TV equipped with an ALPC LED backlight achieved peak luminance of 500 nits and a contrast ratio of 100,000:1 with 30% fewer LEDs and maximum power consumption of 100W.
