Abstract

As cockpit lighting systems have evolved which implement active matrix liquid crystal displays (AMLCD) into military aircraft, it has become obvious that an extremely large dimming range is necessary to accommodate low level night operation and high ambient sunlight conditions. This range may be as large a 0.03 FtL to 200 FtL (6667:1) over the display field of view. This is a much larger range than previously exhibited by typical hot cathode fluorescent lamps. Additionally, performance enhancements are necessary to achieve the high contrast required for sunlight operation in a military environment. These are also complicated by the requirements to start rapidly and operate reliably in environments of -54 degree(s)C to +71 degree(s)C. A significant research and development program has been dedicated to advance the backlight and display technology to achieve the desired performance. This paper will present the results of this effort. It includes data from the benchmarked start through several breadboarded backlight and display enhancements.
