When selecting a Liquid Crystal Display Module or LCD Glass, it is very important to identify the the range of its environmental temperature. Standard Liquid Crystal Displays do not have an extremely wide temperature range, and that range can be affected by solar radiation, ventilation and extremes at different times of the year. Also, you need to be aware of the type of backlighting and control circuitry selected can influence the overall temperature range of the environment.
Another thing to consider that is pertinent to the LCDs temperature range, is that the contrast of the display will change over that range. Your design needs to make allowances for this fact by either adding temperature compensating circuitry to your design, or selecting one of our LCD Modules that already have build in temperature compensation circuitry (Available only is some LCD Graphic Modules ).
TN Temperature Ranges
The operational and storage temperature range of a Twisted Nematic (TN) Liquid Crystal Display is dependant on the drive and voltage of a part. Listed below are the standard, extended and specialized temperature ranges of TN LCDs offered by Pacific Display Devices. .
