The revival of interest in micromechanics gave rise to the terms micro-electromechanical (MEM) devices and systems (MEMS), which may have non-optical functions such as pressure sensing, compared to micro-opticalelectromechanical systems (MOEMS). Scanning laser displays use mechanical scanning systems in conjunction with intensity modulation such as acousto-optic modulation. A very low power version scans the image directly onto the viewer’s retina, and can take advantage of low-power LEDs. Voltage modulation of the LEDs and MEMS deflection makes a compact NTE system with full-color imaging.

However, color sequential filtering is possible with white light emitters. Several features of microdisplays favor early application of OLEDs. They are current rather than voltage controlled, and current control is easier to implement in c-Si. OLEDs are sensitive to contamination and stringent protection favors the compact structure of a microdisplay. The emergence of high-quality, lightweight, head-mounted displays should have a strong influence on expanding market opportunities in that area. 3 Other Applications In principle, the DMD can operate over a wide range of wavelength determined by aluminum reflectivity at short wave, and diffraction at long wave; however, it is limited to near-UV at present.
