Abstract:
Image data for a current image frame may be compensated for transient response variations due to changes to pixel values from one frame to another over time by performing pixel drive compensation. The pixel drive compensation may be performed using a current pixel value and a historical pixel value. The historical pixel value may be the same as a pixel value in the directly previous frame in some conditions, while in other conditions the historical pixel value may be modified from a previous image frame in light of a prior pixel value occurring before the previous image frame. In this way, drive compensation corresponding to image data of a subsequent image frame may be determined based at least in part on a multi-frame history. Even so, the memory bandwidth and/or power consumed to use a multi-frame history to determine a drive compensation may be reduced.
