ABSTRACT:
A driving method of a liquid crystal display is described. The driving method of liquid crystal display firstly detects the maximum grayscale of all pixel of liquid crystal display, and adjusts the out-put brightness of back-light modules in order to provide the corresponding brightness to the pixels of the maximum grayscale. Meanwhile, adjust all grayscale values of all pixels to map a new grayscale value, and drive each pixel. This driving method of this crystal display provides a sharp display quality when displaying darker image, and further reduces power consumption, particularly when displaying low brightness images.
