Redirected from: OLED microdisplay
Definition: microdisplay
A microminiaturized display, typically with a screen size less than two inches diagonal. Microdisplays 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.
Transmissive, Emissive and Reflective
LCD microdisplays are transmissive, allowing light to pass through the display like LCD computer screens. OLED microdisplays are emissive and generate white light that passes through color filters. DLP microdisplays used in projectors and AR/VR glasses reflect light into the viewer's lens or the projection lens. See DLP and rear-projection TV.

This amazing screen is used in HMDs and digital camera viewfinders. The reflective LCD display provides an 800x600 resolution in a half-inch screen that uses only 45 milliwatts of energy, as much as ten times less than transmissive displays. (Image courtesy of Three-Five Systems, Inc.)
