Abstract:
1. A liquid crystal display (LCD) overdriving method for improving displaying quality and a response speed of an LCD, comprising the following steps of: receiving, by a scaling controller, a previous frame image grayscale value and storing the previous frame image grayscale value into a frame buffer of the scaling controller; and receiving a next frame image grayscale value by the scaling controller and sending the previous frame image grayscale value and the next frame image grayscale value to a time schedule controller independent from the scaling controller so that the time schedule controller looks up a lookup table and outputs an overdriving grayscale value; wherein the previous frame image grayscale value and the next frame image grayscale value are sent to the time schedule controller pixel by pixel, when outputting of a overdriving grayscale value of a pixel is completed, the previous frame image grayscale value and the next frame image grayscale value of the pixel are removed from a memory space of the time schedule controller and then a previous frame image grayscale value and a next frame image grayscale value of a next pixel are stored in the memory space.
