Abstract

The Aerospace and Defense display industry is in the midst of converting light the sources used in AMLCD backlighting technology from fluorescent lamps to LEDs. Although challenging, the fluorescent backlighting technology delivered good product in high end applications. LEDs, however, have the promise of even greater efficiency and lower cost. The history of LED backlighting is short and very dynamic; expectations are high and promises are many. It appears that for engineers developing backlights for high performance displays life has not become easier with the change of the technology. This paper will discuss just one of many challenges engineer's face: operation of LED backlights in high temperature environments. It will present experimental data showing several advantages of the RGB LED technology over other lamp technologies for high performance commercial and military application.
