This paper describes the construction and performance of an LED numeric display designed specifically for aircraft cockpit applications. The display, using yellow or green LED chips, is a 4-character 7-bar numeric with 4-mm character height mounted in a hermetically sealed package to meet full military device specifications. Legibility studies are reported for this display in ambient illuminations up to 100,000 lux, using different, commercially available contrast-enhancement filters. The results show that the display is completely legible in the highest illumination for a relatively modest power consumption.
