Abstract

A new miniature color display technology has been developed for airborne helmet-mounted applications. A stack containing three AMLCDs, operating in a subtractive-color mode, is used to obtain 400 X 300 full-color pixels in a 3.3 X 2.5-cm (1.3 X 1.0-inch) active area, yielding a resolution of 118 pixels/cm (300 pixels/inch). Display luminance and contrast are sufficient to produce a 2:1 contrast ratio under worst-case airborne viewing conditions, using typical helmet-mounted display optics. Considerations that led to the selection of this technology for development, results, and future plans are discussed.
