Discharge lamp including an integral cathode fall indicator
Abstract:
An active matrix liquid crystal display (AMLCD) system is for use in avionic applications. The system includes an integral cathode fall indicator. The indicator relies on a gas fill mixture to provide an orange glow when the cathode fall region has an abnormally high potential across it. During normal operation, the gas fill mixture provides a light blue glow. The gas mixture includes helium, neon, argon, krypton, and xenon.
