Patent ID: 8471795

Claim:
A pixel driving method, comprising: receiving a first target grey level to be displayed by a pixel during a first frame period; generating a first higher grey level and a first lower grey level according to the first target grey level and a look up table; displaying the first higher grey level and the first lower grey level during a first sub-frame period and a second sub-frame period of the first frame period, respectively, wherein accumulated luminance of the first higher grey level over the first sub-frame period of the first frame period and the first lower gray level over the second sub-frame period of the first frame period is equal to accumulated luminance of the first target grey level over the first frame period; receiving a second target grey level to be displayed by the same pixel during a second frame period, the second frame period being immediately subsequent to the first frame period; generating a second higher grey level and a second lower grey level according to the second target grey level and the look up table, the second higher grey level being greater than the first higher grey level, and the second lower grey level being smaller than the first lower grey level; and displaying the second higher grey level and the second lower grey level during a first sub-frame period and a second sub-frame period of the second frame period, respectively, wherein accumulated luminance of the second higher grey level over the first sub-frame period of the second frame period and the second lower gray level over the second sub-frame period of the second frame period is equal to accumulated luminance of the second target grey level over the second frame period, wherein said generating the second higher and second lower grey levels are performed to minimize a luminance difference between (i) a luminance of the pixel in accordance with the first lower grey level and (ii) the luminance of the pixel in accordance with the second lower grey level.
