ABSTRACT:
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.
