Patent Images

1. A method of using raw grayscale image data representing images to be displayed in a plurality of successive frames, to drive a display having a plurality of pixels that include a drive transistor and an organic light emitting device, said method comprising:

  • dividing each frame into at least a long sub-frame and a short sub-frame, a time period of the long sub-frame being greater than a time period of the short sub-frame;

    determining which of a plurality of predetermined grayscale value ranges a raw grayscale value for a pixel during a frame falls within; and

    supplying the pixel with drive currents during each of the long sub-frame of the frame and the short sub-frame of the frame based upon said determined grayscale value range,wherein the drive current supplied to the pixel during the long sub-frame is greater than the drive current supplied to the pixel during the short sub-frame when the determined grayscale value range is a first predetermined range of grayscale values.
