Paper Abstract

An efficient, high intensity, mercury free cathode luminescent lamp/power supply assembly has been designed for use in the backlighting of AMLCD's. It has demonstrated excellent spectral stability over the temperature range of - 55 to 70 degrees C and its dimming range of 1 to 10,000 Ft-L. The CLL has a projected useful life of 10,000 hours. A life test sample currently has 5,000 hours with a decrease of 16% from its' initial level.
