Abstract

Recent advances of LED-lit LCD TVs are reviewed. The influence of LED backlight on the color performance, electro-optic characteristics of the LCD TVs, and color-sequential LCDs are emphasized. The LED backlit LCDs not only exhibits a wider color gamut but also has a∼ 1.3-2.5X smaller color shift than that of CCFL-BLU especially when there are no color filters used. Wide view angle of higher than 100:1 within the 85°viewing cone can be guaranteed with the optimal film compensation schemes. The LED light source as a 2D adaptive dimming backlight not only enhances the viewing angle but also lowers the power consumption. A thin twisted-nematic cell filled with a high birefringence exhibits a response time less than 2 ms, which is attractive for color sequential display using RGB LEDs.
