Optimal local dimming based on an improved greedy algorithm

Applied Intelligence, 2020
As a new technology appeared in recent years, the local dimming can effectively reduce the power consumption of a display system and improve its display effect. A suitable local dimming algorithm should have efficient performance and can make the displayed images have higher visual quality.

Adaptive local backlight dimming algorithm based on local histogram and image characteristics

open access: yesSPIE Proceedings, 2013
Liquid Crystal Display (LCDs) with Light Emitting Diode (LED) backlight is a very popular display technology, used for instance in television sets, monitors and mobile phones. This paper presents a new backlight dimming algorithm that exploits the characteristics of the target image, such as the local histograms and the average pixel intensity of ...

64.4: Smart Algorithms for Local Dimming LED Backlight

Digest of Technical Papers SID International Symposium, 2008
Abstract To reduce power consumption and improve image quality including contrast ratio and color gamut, LED backlight units (BLUs) consisting of many small blocks in 2‐dimensional space are implemented. Either white‐gray‐level luminance or color is controlled by the local dimming LED BLU.
