Liquid crystal display with RGBW pixels and dynamic backlight control

摘要

A liquid crystal display (LCD) capable of converting input RGB data into RGBW data to provide the RGBW data to a panel. The LCD simultaneously controls the light level of a backlight and the amount of the RGBW data to prevent RGBW picture quality from being damaged in pure color data, minimizes the power consumption of the LCD, and applies the above to a CPU interface method as well as an RGB interface method.
