Paper Abstract

Your man/machine interface must be available 100% of the time. Naturally, your display therefore must be an environmentally ruggedized, full color, tri-notch filtered, high-contrast, sunlight readable, active matrix liquid crystal display (AMLCD) with a heater, a cold-cathode fluorescent backlight, and dual mode day/night dimming ranges. For graphically rich, multifunction indication with a need for full color, this could be so; but for a dedicated-function or alphanumeric multiple function display, the size, cost of packaging that AMLCD into your available envelope could be prohibitive; not to mention the latent expense of managing the source stability risks. For dedicated functional requirements a rugged, backlit direct drive or low mux rate segmented or dot matrix transflective LCD may be a very cost effective solution. Three instruments that provide just such a solution for a bubble canopy environment and that also include NVIS Green A chromaticity and NVIS Class A radiance-compliant LED backlighting will be reviewed, along with their operational requirements.
