Cooperative local dimming for accurate backlight brightness matching
Electronics Letters, 2011 A cooperative local dimming (CLD) method that effectively controls the brightness of the backlight unit is proposed. This CLD method takes into account the brightness of neighbouring light sources to achieve a backlight brightness that should be minimally higher than the brightness required by the pixels on the screen.

Image dependent energy-constrained local backlight dimming [PDF]
2012 19th IEEE International Conference on Image Processing, 2012 In this work, we consider and propose two extensions to an optimization-based image dependent backlight dimming algorithm. The first extension introduces error weighting based on human perception of luminance, aiming to improve the perceived image quality; the second extension adds an adjustable term for power consumption to the cost function, allowing
