  • LCD Temperature Ranges

     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. .

TN Standard Temperature Range Summary (-S)

Drive Method Static Multiplexed (3V) Static Multiplexed (5V)
1/2 1/3 1/4 1/8 1/16 1/2 1/3 1/4 1/8 1/16
Operating Temperature C -10 to +60 0 to +50 -10 to +60
Storage Temperature C -20 to +60 -20 to +60

TN Wide Temperature Range Summary (-W)

Drive Method Static Multiplexed (3V) Static Multiplexed (5V)
1/2 1/3 1/4 1/8 1/16 1/2 1/3 1/4 1/8 1/16
Operating Temperature C --- --- -40 to +80 -30 to +80 -20 to +70
Storage Temperature C --- -40 to +80


TN/FSTN Temperature Ranges
The operational and storage temperature range of a Super Twisted Nematic (STN) and Film compensated STN (FSTN) LCDs are set pretty much into two ranges for our standard product offering. Listed below are the standard, extended and specialized temperature ranges of STN and FSTN LCDs offered by LONGTECH Devices.

STN/FSTN Standard Temperature Range
Operating Temperature: 0C to +50C
Storage Temperature: -10C to +60C

STN/FSTN Extended Temperature Range
Operating Temperature: -20C to +70C
Storage Temperature: -30C to +80C
