Subject: Failure Rates for Active Matrix LCDs and Cold Cathode Backlight
Hello there, I am looking for failure rate information for active matrix LCD panels, and also for cold cathode backlights (Airborne Inhabited Fighter envrionment if possible, but not necessary). If anybody can suggest a suitable data source (or better still email me a failure rate) I would greatly appreciate it. Thanks in advance, Richard.

Information on LCD displays appears to be difficult to obtain. The panel displays in the F-22 Advanced Tactical Fighter were the first multifunction LCDs used in a military cockpit. The expected MTBF is 10,000 to 20,000 hours depending on what failures you want to discount, such as maintenance errors, operator errors and cannot duplicate. I could not find any information on cold cathode back lighted displays
