DLP® projection technology

Abstract

This chapter provides a general introduction to a unique projection display technology based on a microelectromechanical system (MEMS) device known as the DMD (digital micromirror device). The complete system together with controlling electronic devices is marketed by its creator - Texas Instruments - under the name DLP®. DLP is most widely used in projection display systems from tiny LED-illuminated picoprojectors to the world’s brightest high-quality giant screen cinemas. The technology has proven to deliver both the highest spatial resolution and most stable and accurate colors at impressive reliability and resilience. This chapter provides an introduction to the basic principles of operation for this technology in projection display applications of all forms.
