摘要： A method for driving an active matrix display wherein each image frame is divided into a number of displayed frame portions, each of which is followed by a darker frame portion. The image data in the darker frame portion is removed so as to allow the pixel luminance to diminish. The temporal separation between the displayed frame portion and the following darker frame portion is smaller than a frame time. In a display where the lines are driven repetitively for forming the display image in a plurality of frame times, the image data provided to a pixel, after the luminance in that pixel changes from low to high, is adjusted so that the brightness of the pixel in the preceding frame times appear higher or not lower than that in following frames times.

摘要： 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.

摘要： 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.
