Abstract
Data projectors are the preferred display technology for screen sizes larger than 1.5 m. Their main application is the group viewing of business presentations and related data. The technologies involved are multidisciplinary and include electronics, optics, and mechanics. The image is generated on the surface of a microdisplay, which is typically a micromirror or liquid crystal device that provides the desired resolution. The light is generated by a very high-luminance light source, which illuminates the microdisplay. A projection lens then provides the desired magnification to fill the screen. There are a number of optical components needed in between to shape the light correctly (spatial and spectral domain).
