Patent ID: 7643021

Claim:
A method for driving image data on a display, wherein the display comprises a plurality of pixels, the driving method comprising: writing a first frame image data into the pixels and then refreshing the pixels from the first frame image data to a black frame data, wherein the first frame image data and the black fame data both are of n bits; inputting a second frame image data Gn to an advance overdrive module, wherein the second frame image data is of n bits; converting the second frame image data of n bits into a calculated image data, wherein a is a positive integer, and the calculated image data is acquired from multiplying the second frame image data Gn by 2 (a) ; after producing the calculated image data, adding a boost of n bits into the calculated image data to acquire an overdrive image data Gn′ of (n+a) bits, wherein the boost is of n bits and acquired according to the black frame data and the second frame image data Gn in a Look-Up table, and the overdrive image data Gn′ is of (n+a) bits; selecting n bits data from the overdrive image data Gn′ having (n+a) bits as a selected image data; and using a partial frame rate control module to output an output image data Gn″ to a corresponding frame of multiple frames which are utilized to smooth the overdrive image, wherein the output image data Gn″ is of n bits, and the output image data Gn″ is acquired by combining the selected image data and an output gray level data of n bits of the relationship between a pattern and the corresponding frame together.
