LCD/VFD Storage Temp

HI Guys,



We have a military application where they would like a storage temperature of -60F. We are currently using an LCD but is storage temperature is limited to -30C.



I've checked various LCDs and VFD and the lowest storage temp I can find is -40C. I've also talked with major LCD and VFD manufacturers and they did not know if either would work that low.



The customer is thinking about reverting back to 7-segment displays, assuming the LED storage temp could be lower.



Question: does anyone know of any ultra low temp LCDs or VFDs that might be usable. Would simple LED displays store lower than LCD or VFD?



Thanks!

-60C is not a problem. We have delivered -70C LCD before. -80C would be possible but expensive, with low yield. How big is your LCD?

OLED would likely have the same limitations of -40C typical. Specially made units are possible down to -55C.

-70C STN LCDs are proven technology. However, only a handful of factories are capable of making them.

Again, we can make LCDs with -45C to +70C operating and -70C to +80C storage temperature. We can make them in single, multi or full colors, with or without backlights.
