GRAY-SCALE VOLTAGE PRODUCING MODULE AND LIQUID CRYSTAL DISPLAY HAVING THE SAME AND DRIVING METHOD THEREOF

摘要

A grayscale voltage generating module, a liquid crystal display having the same and a driving method thereof are provided to facilitate RGB color calibration by applying different grayscale voltages to respective RGB pixels. A grayscale voltage generating module includes a first voltage input terminal, a second voltage input terminal, at least one LCD(Liquid Crystal Display) driving voltage converter(610,620,630,640), and grayscale generators(650,660). An LCD driving voltage is input to the first voltage input terminal. A ground voltage is input to the second voltage input terminal. The LCD driving voltage converters(610,620,630,640) generate LCD driving voltages with different levels according to RGB data. The grayscale generators generate different grayscale voltages according to the LCD driving voltages.
