Compensation accuracy
First Claim
1. A method of driving a display, the display for displaying image data in successive frames and having pixels that include a drive transistor and an organic light emitting device, said method comprising:
- dividing each frame into a plurality of sub-frames,supplying a pixel with a drive current that is based on data comprising said image data during one of said sub-frames, andsupplying the pixel with a drive current that is based on data comprising compensation data during at least two of said sub-frames, the compensation data divided among said at least two of said sub-frames,thereby compensating for at least one of performance and a property of said pixel.

Abstract
A system uses image data, representing images to be displayed in successive frames, to drive a display having pixels that include a drive transistor and an organic light emitting device by dividing each frame into at least first and second sub-frames, supplying the image data during one of the sub-frames, supplying compensation data during the other of the sub-frames, compensating image data based on the compensation data, and supplying each pixel with a drive current that is based on the compensated image data during each frame. The compensated image data may be supplied from a driver having a preselected data resolution, and the system determines whether the compensated image data is greater than the data resolution of the driver, and if the compensated image data is greater than the data resolution of the driver, transfers the excess compensated image data to a different sub-frame.
