Abstract :
This paper describes recent advances in digital micromirror device (DMD) technology for projection television (PTV) applications, including a new device called the hidden hinge DMD with improved optical efficiency and contrast ratio. The DMD is a micromechanical, reflective spatial light modulator monolithically fabricated over a conventional CMOS SRAM address circuit. A 768/spl times/576 pixel array DMD (442,368 mirrors) has been developed for and demonstrated in one-DMD and three-DMD PTV systems having diagonals ranging in size from 42 inches to 13 feet.<>
