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 storing 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; and
a color decoder for receiving the 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.

Abstract
Systems and methods of color data driving for light emissive visual display technology, and particularly to systems and methods for driving pixels with more than three primary color subpixels. Only a subset of the total number of subpixels per pixel are driven at any one time reducing the number of decoders/DACs. The decoders/DACs are coupled by a color decoder only to the active subpixels using a switching fabric.
