A microminiaturized display, typically with a screen size less than two inches diagonal. They are used in rear-projection TVs and their data projector counterparts, in head mounted displays (HMDs) and in the viewfinders of digital cameras. Although microdisplay research goes back to the mid-1980s, commercial products emerged in the late 1990s.

Reflective and Transmissive
Reflective microdisplay bounce light into the viewer's lens or the projection lens. For example, in a DLP microdisplay, tiny mirrors divert light into the projection path (see DLP).

LCD microdisplays are transmissive, allowing light to pass through the display like backlit, laptop computer screens. See rear-projection TV.
