Abstract

Micromachining technology can enable a new generation of portable projection-video displays that are lower in weight, power consumption, and cost than displays that are available today. Emerging micromachined projection video display technologies fall into three general categories:
  1. 1.

    Two-dimensional arrays. Texas Instruments’ Digital Light Processor (DLP) display [93] and reflective LCD displays use one reflective element for each pixel. The reflected elements are imaged onto the projection screen to form the two-dimensional image.

     
  2. 2.

    Scanned one-dimensional arrays. Silicon Light Machines’ gratinglight-valve display uses one scanning mirror and a one-dimensional array of light modulators [94] to generate a two-dimensional image [95]. Another scanned one-dimensional array display has been made using an array of switched laser light sources and one scanning mirror [96].

     
  3. 3.

    Raster-scanned. Raster-scanned displays use two mirrors scanning in orthogonal directions or a single gimbaled mirror scanning in two dimensions, and a modulated light source to generate a 2-D image [97]. Such displays have been demonstrated for direct virtual projection displays [98] and laser projection displays [99].
