Abstract

Aircraft manufacturers, with their low production levels, rigorous optical requirements, and extreme operational environmental conditions, have a difficult time obtaining a consistent supply of AMLCDs suitable for aircraft applications. Overall demand is so low that every AMLCD needed for many years of present day aircraft delivery rates could be produced in less than one day by a major AMLCD manufacturer. The most obvious solution to this supply problem is to find a way of using commercially available AMLCDs in aircraft applications. Many display suppliers have developed a methodology to remanufacture commercial AMLCDs for more extreme operational environments, but one problem still remains - the commercial AMLCDs are not produced in the correct sizes or shapes needed for aircraft. An innovative display supplier has developed a technique to resize the commercial AMLCDs to fit into existing aircraft applications. Could this be the solution to the supply dilemma? This paper will discuss the approach The Boeing Company and BAE pursued to determine the feasibility of using resized AMLCDs in our product lines. Specialized accelerated tests were used to provide initial indications of seal durability. More routine thermal and humidity tests were also performed to assess longer term seal reliability. Optical assessment techniques will be presented along with our future plans for this technology.
