The major efficiency loss in current liquid crystal displays(LCD) are the absorption in polarizers and color filter, and both can be resolved with decent backlight design which takes light polarization and color separation into consideration. Those improvement schemes on the backlight normally will not trade off the image quality readily achieved in the commercial LCD. Both polarization and color separation schemes for the backlight are reviewed with categorization on the basic concept, followed by the proposal of possible combinations for both direct lit and edge lit configuration with the consideration on the availability of associated components. Two total solutions, including polarization conversion module for LED and pixelized backlight with RGB LED for direct lit and edge lit respectively, are given with demonstration of preliminary result achieved so far as the efficiency improvement schemes for LCD backlight.
