Paper Abstract

Active Matrix, Liquid Crystal Displays (AMLCD) are being used extensively in severe environments which require a wide range of optical performance. Conditions vary from high performance military aircraft to rugged use on the ground in both military and commercial vehicle environments. Not only are these displays being exposed to high ambient temperatures, shock and vibration, but also the requirement for readability in direct sunlight imposes conditions where backlight brightness must be greatly increased, imposing added thermal requirements. This paper discusses a fluid immersion, liquid cooling technique that allows great increases in backlight brightness with major improvement in thermal efficiency of the display. Improvements in susceptibility to shock and vibration can also be deduced from the use of this methodology. A prototype has been developed and is described in this paper and results compared to a conventionally cooled unit. A number of other advantages, which result from liquid immersion, are also discussed.
