Reflective color displays are coming to the market from several vendors. Most use patterned color filters to impart color to white light, and arrange the patterned color filters over independently switched sub-pixels. Three sub-pixels generally form a full color pixel, though occasionally four or more subpixels are employed per pixel. Various color generation schemes are used. The most common is three sub-pixels in a red, blue and green set. However subtractive filter sets are also used, such as a cyan, magenta, yellow etc. The actual color filter materials generally use either a dye material, or a dispersion of pigmented particles.
