The demand for increased information content and improved image quality on matrix displays has driven the display manufacturer to provide very high pixel density displays. The new generation displays have very low luminous transmittance, 2 % to 4 % typical. The consequence of manufacturing high density, low transmittance displays is a that disproportionate burden of performance is placed on the backlight system. Low heat, high luminous efficiency, high dimming ratio backlight systems are the key to success of these growing display technologies. Backlight systems with luminous efficiencies greater than 65 lumens per watt are now available for use with high density displays. These backlight systems lend themselves well to a wide variety of applications including commercial automotive, general aviation aircraft, and advanced military aircraft and ground vehicles where high performance is critical
