Backlight modulation, when coupled with gamma remapping, can significantly increase the performance of a TFT LCD panel in terms of contrast ratio, black level and power consumption. A programmable gamma reference buffer with integrated backlight control has been developed to support dynamic gamma control in conjunction with backlight control to enable performance enhancements in notebook computers and LCD televisions.
