Patent ID: 7656374

Claim:
A method for enhancing the response speed of a display device, said display device having a panel and a backlight module positioned behind said panel, said panel having a plurality of horizontal scan lines, a plurality of vertical data lines, and a plurality of pixels each located at the intersection of a said data line and a said scan line, a said pixel being turned on by enabling said scan line, applying a driving voltage via said data line, and illuminating said backlight behind said pixel, each said pixel having a delay property where a grey level of said pixel approaches a target grey level corresponding to a target driving voltage, said method comprising the steps of: receiving a sequence of input frames having an input frame rate and outputting a sequence of output frames having an output frame rate equal to p/q (p, q being natural number and p>q) times of said input frame rate; wherein, in a period of time equal to the least common multiple of the input and output frame times, q input frames are output and (p−q) transient frames are generated and inserted to at least one of (q+1) appropriate places before or after said q output frames in said output frame sequence; and each said transient frame is produced based on the complete data of a latest completely received said input frame and the data of an input frame concurrently received; wherein one of every two adjacent said output frames is replaced by a black frame; and, when three identical said output frames are to be output in a row and for two consecutive ones of said three output frames, the pixels of said two output frames are applied with said target driving voltages.
