1. A color data driver for an emissive display system having pixels, each pixel having a number of primary color subpixels, each primary color subpixel having a light emitting device, the color data driver comprising:

  • data storage for receiving color data for a number of active primary color subpixels of a pixel, the number of active primary color subpixels less than a number of primary color subpixels of the pixel;

    decoders for performing digital to analog conversion of the color data to generate analog color data, the number of decoders corresponding to a preset maximum number of active primary color subpixels of a pixel which is less than the number of primary color subpixels of the pixel; and

    a color decoder for receiving the analog color data for the number of active primary color subpixels and for providing the color data for the active primary color subpixels to the pixel, the color decoder comprising;

    a switch fabric controllable to select a switching state being a combination of switching from color data inputs of the color decoder to color data outputs of the color decoder with use of color bits provided to the color decoder, the switch fabric for, according to the switching state, switching to each color data output one of at least one color data input, and for switching to at least one color data output, one of at least two color data inputs.
