Abstract
An organic light emitting device display may be compensated for color variations between sub-pixels of the same expressed color. This may be done initially upon manufacture of the display and may be continued and updated in the course of the display'"'"'s lifetime to compensate for differential effects of aging on different expressed sub-pixels. In accordance with one embodiment of the present invention, the display may be driven to achieve a color gamut that substantially all of the pixels are capable of achieving.
