Compensation accuracy

A method of using 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, said method comprising:

• dividing each frame into a plurality of sub-frames,
• dividing compensation data among said sub-frames, and
• supplying a pixel with a drive current that is based on data comprising a division of said compensation data during each sub-frame into which said compensation data is divided,
• thereby compensating image data based on said compensation data to compensate for at least one of aging and non-uniformity of said pixels.

An apparatus for using image data representing images to be displayed in successive frames, to drive a display having an array of pixels that each include a drive transistor and an organic light emitting device, multiple select lines coupled to said array for delivering signals that select when each pixel is to be driven, and multiple data lines for delivering drive signals to the selected pixels, said apparatus comprising:

• a source driver coupled to said data lines and including a processing circuit for receiving said image data and adapted to
• divide each frame into a plurality of sub-frames,
• supply a pixel with a drive current that is based on data comprising said image data during one of said sub-frames, and
• supply 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,
• to thereby compensate said image data based on said compensation data to compensate for at least one of aging and non-uniformity of said pixels.
