Patent ID: 7705802

Claim:
A method for diffusing errors in a display device, comprising: a) separating a frame of an input video signal into at least two subframes; and b) applying an error diffusion process to each subframe of the at least two subframes utilizing an error diffusion unit corresponding to each of the at least two subframes, wherein errors from a first sub frame of the at least two sub frames are transmitted to the error diffusion unit corresponding to a second subframe of the at least two subframes, and errors from the second subframe are transmitted to the error diffusion unit corresponding to the first subframe, the errors from the first subframe are at least partially mixed with the errors from the second subframe, and an error diffusion coefficient is applied to the mixed errors, wherein a first pixel in the first subframe receives errors from the second subframe concurrently to when a second pixel in the second subframe receives errors from the first subframe, the first pixel adjoining the second pixel on a same row of the frame.
