Help Getting ArduinoPro Mini 3.3V and NHD-C12864A1Z-FSW-FBW-HTT to work via SPI

For more difficult it seems to be done, Lumex manufactures some LCDs with operating and storage temperatures of -40~+85 °C... I wonder why Newhavan doesn't, once it is one of the of the world's biggest display modules manufacturers.

I wish to use NHD-0216K1Z-FL-YBW in some projects but it doesn't meet our temperature requirements. So I have some questions below:
1) Is there any physical characteristic that limits operating/storage temperature range to -20~70 °C?
2) What happens if these limits are exceeded temporarily to -40 or +85 °C? Does the display simply stop operation and resume when the temperature returns to normal values (with reduction of its lifetime)? Or can it be definitively damaged even if it is exposed to those temperatures for short time intervals?

  HI,
  
  Our standard displays are rated to handle -20° C up to +70° C, this range satisfies the requirements for most of our users, however it is possible to create a custom module that would be able to operate up to +85° C.
  
  It is hard to say what would happen to the display when it is brought up to a temperature that exceeds +70°. This has a chance of having dead pixels or dead portions of the display. Another possible issue is a damaged polarizer. However we are able to customize displays that would be able to safely be operated up to +85°C.
   
  The cold could also affect the display, at colder temperatures the liquid crystals themselves could start to freeze and expand. This could cause cracks and leaks of the LC inside the display. One recommendation is to use a heating element with your display to avoid damage caused by cold weather.
  
  If the display is brought to an extreme condition momentarily it might still be able to function properly, but it is not recommended.

  Thank you, Saurabh_B.
  
  Could you estimate the costs, minimal order quantities and lead time of the NHD-0216K1Z-FL-YBW display modified for -40 ~ +85 °C operation temperature range? I supose that our anual consumption will be 1,000 to 2,000 pcs.
  
  Regards.

  Hi, Saurabh_B.
  
  Please quote too the same display for -20  ~ +85 °C.
  Concluding, I wish to receive quotation for the display NHD-0216K1Z-FL-YBW customized for -40 ~ +85 °C (with heater) AND for -20 ~ +85 °C (without heater).
  
  Regards.
