Abstract
A sequential color system is provided in which a processor (22) is coupled to a memory (24) and a receiver (27). Images are generated by shining light from a light source (28) through a color wheel (30) and onto DMD array (26). Light from the DMD array (26) is shone on screen (32). By adjusting the speed and make-up of color wheel (30) color separation is greatly reduced or eliminated. Also there are techniques for sequential imaging which may be applied to other technologies, such as CRT technologies.
