1. A method of using a compressed gamma in a video display having an array of pixel circuits, each of the pixel circuits including an organic light emitting device, the method comprising:

  • defining a subset of a dynamic gamma range bounded by an available voltage range of a source driver of each of the pixel circuits,allocating a scale of bits to the defined subset to produce a compressed gamma range,shifting the compressed gamma range up or down according to an aging of the pixel, andapplying the compressed gamma range to a video signal applied to the display.
