Abstract
Display technologies in mobile, tablet, laptop, desktop and TV have been used from day to day. As a new member of display technologies, microelectromechanical systems (MEMS)-based displays, compared with traditional display mode like LCD and OLED, show merits on optical performance, color performance and energy-saving. In this talk, different display modes of available MEME-based display technologies, such as digital micromirror device (DMD), digital micro-shutter (DMS), interferometric modulator display (IMOD), time multiplexed optical shutter (TMOS) and grating light valve (GLV) and their operational concepts as well device principals for transmissive, reflective and projection displays are presented. These devices are achieved by controlling light by transmittance, reflective or diffraction behaviors. The issues in the reliability tests are stressed and the solution for these problems are presented. The challenge and new opportunities on material science involved in MEMS technologies are proposed.
