Patent ID: 7791583

Claim:
A method of operating a display, comprising: deriving first pixel data for overdriving pixel circuits of the display relative to target gray levels based on values in a first lookup table and a second lookup table stored in memory; rendering the second lookup table unavailable in memory in response to a change in an operating condition of the display; deriving second pixel data using the first lookup table for overdriving the pixel circuits when the second lookup table is unavailable in the memory; using the first lookup table and the second lookup table for overdriving the pixel circuits when the temperature of the display is within a first range; and using the first lookup table and a third lookup table for overdriving the pixel circuits when the temperature of the display is within a second range, the first lookup table including base values of overdrive gray levels, the base values representing coarse estimates of the overdrive gray levels, the second lookup table including offset values representing refinements to the coarse estimates for a first temperature range, the third lookup table including offset values representing refinements to the coarse estimates for a second temperature range.
