Abstract
Displays are provided with circuitry performing color correction to compensate for the displays' luminance and chrominance transfer characteristics. Some techniques are suitable for RGBW displays and for subpixel-rendered displays. Some displays include an external light source (e.g. a backlight unit in LCDs), and the color correction is coordinated with dynamic control of the light source.
