I'm creating some specifications for a 6" color graphics flat panel display in a rugged environment application that requires wide temp range, sunlight readable, shock & vib resistance, etc. I've embarked on an effort to learn more about LCDs and especially what all the vendor specs *really* mean and what options are out there. I'm picking up tidbits from trade magazines, vendor websites, and other web sites like the US Display Consortium, but I can't find any kind of article or book that provides comprehensive guidance on rugged LCD selection that is current. Like for example what makes one CCFL backlight more rugged than another one ? I've yet to find a salesperson who can really answer my questions other than to say yeah ours does all that.
Using the go with what everybody else is doing technique, I can see that the general trend in rugged flat panel displays now is for active TFT LCDs with CCFL backlights and transflective screens, with some moves to LED backlighting. But I want to understand the specs and tradeoffs.
Does anybody have any ideas on articles or books that have comprehensive and timely info on flat panel display selection in rugged applications, with a slant on LCDs ? Or even ruggedization techniques for sunlight readable commercial grade LCDs ?
