MEMS-based Technologies for Mobile Multimedia Displays & High Definition Television

Abstract —The Technology of Micro Electro Mechanical Systems (MEMS) is revolutionizing the architecture of Sensors, Mobile Multimedia Phones, Media Tablets, Laptops, Projectors,   Cinema Screens and High Definition Television (HDTV), amongst, countless other applications in many fields of engineering. This paper deals with MEMS-based Technologies for Mobile Multimedia Displays and HDTV.  Basic concepts of Liquid Crystal Display (LCD) Technology are discussed. MEMS-based display technologies namely Digital Light Processing (DLP) of Texas Instruments, Digital Micro Shutter (DMS) of Pixtronix and Interferometric Modulation (IMOD) of Qualcomm MEMS Technologies are introduced. The architecture of the DLP light switch MEMS chip containing two million hinge-mounted mirrors of about 10X10 μm² each is presented. The design concepts of ultra low power consumption, exceptional image quality and sunlight-viewable MEMS-based technology for mobile multimedia applications are discussed. Design Methodology of MEMS is briefly touched standing on the shoulders of the VLSI technology
