The fabrication techniques, control strategy, and electromechanical modeling and performance of digital micromirror devices (DMD) are discussed. Some of the potential artifacts inherent in a pulse-width-modulated display and their amelioration in digital light processing (DLP) systems are described. DLP is a revolutionary way to project and display images. The key elements of the technique include the signal source - generally computer graphics or video, coupled with memory and signal processing in the front end of the system, a light source, color filters, optical elements to couple the light from the source onto the device and from the device to the viewing screen, and the DMD.
