Light-emitting diodes (LEDs) have realized substantial advancements over the past twelve years since Rockwell Collins
began designing LED backlights, resulting in performance improvement and cost reduction for avionics displays.
Display and backlight packaging approaches have evolved to address the challenges associated with these LED
improvements and the backlight emitter count reductions that followed. The objective of this paper is to discuss the
backlight and display packaging design adaptations that helped avionics displays benefit from these LED improvements.
Rockwell Collins serves both the military and the commercial segments by exploiting the common elements of these applications. Rockwell Collins has created a liquid crystal display family capable of 100:1 contrast ratio, 40:1 high ambient contrast, 0.25% specular reflectance, 0.1% diffuse reflectance, enhanced color stability over +/- 55H, 0-30V field of view, 300 fL with 10K:1 dimming range, color NVIS B compliance while exceeding environmental performance requirements though ruggedization. In order to meet the full range of display requirements at a system level, all the components must be understood and managed to meet the end solution of the final system. This paper details Rockwell Collins' optical performance using an avionics grade panel, third generation custom compensation, and solid state backlight.
