A method for driving a liquid crystal display includes: a) receiving a video signal from a first group of gray scales values; b) comparing a current frame of the video signal with a previous frame to determine whether the current frame is in a static state or in a dynamic state; c) when the current frame is determined to be in the static state, converting the video signal to a driving signal; d) when the current frame is determined to be in the dynamic state, calculating a overdrive signal. The value of the driving signal is selected from a second group of gray scale values having at least one decimal point gray scale and having the same number of gray scale values as that of the first group of gray scale values. The value of the overdrive signal is selected from the first group of gray scale values.

A LCD (Liquid Crystal Display) with improved motion image quality and a driving method therefor. The LCD includes a pixel, a data driving circuit and a scan driving circuit. The data driving circuit generates over driving pixel data and gray pixel data according to pixel data of a Nth frame and pixel data of a (N+1)th frame, and outputs driving voltages, which correspond to the over driving pixel data, black pixel data and the gray pixel data, to the pixel at first, second and third time. The scan driving circuit outputs a scan signal at the first time, second time and third time to enable the pixel to receive the driving voltages corresponding to the over driving pixel data, the black pixel data and the gray pixel data. The driving voltages enables the pixel to generate a brightness curve similar to a pulse curve.

An over-driving device is provided. In a first frame, a compression circuit compresses a first image signal to generate a first compression image signal, and a buffer temporarily stores the first compression image signal. In a following second frame, the compression circuit compresses a second image signal to generate a second compression image signal, and the buffer outputs the first compression image signal to serve as a first buffer image signal. A comparison circuit compares the second compression image signal and the first buffer image signal and generates an enable signal according comparison result. A decompression circuit decompresses the first buffer image signal to generate a previous image signal. An over-driving unit receives the second image signal to serve to a current image signal and receives the previous image signal and the enable signal. The over-driving unit over drives the display device or not according to the enable signal.
