When is the heater required on NHD-C12864A1Z-FSB-FBW-HTT
« on: February 03, 2019, 10:06:04 AM »
I have a low power application required to operate in -40C operating temperature.
NHD-C12864A1Z-FSB-FBW-HTT display is rated for -40C but is that with the heater running or without the heater running?
When is the heater needed?

Hi Gary,

This display is rated to -40C with the heater running.  With the heater off, it is rated to -30C.
As the temperature cools down to -30C, the contrast of the display will begin getting lighter.  Therefore, it is best to start heating before it gets down to -30C to maintain the contrast level as the display gets closer to -40C.

Best Regards,
