LCD Temperature Ranges


LCD Temperature RangesWhen 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. 

Outlined in this section are the basic temperature ranges of the LCD Modules and LCD Glass parts offered by Pacific Display Devices.  The temperature ranges in this section are valid when this page was put onto the net.  However, Pacific Display Devices is always pushing the envelope of LCD technology  with ongoing product development and adding capabilities to our products, which include pushing the bounds of the temperature range of the LCD products. So if you do not see your requirements here, please contact us and ask us about it: inquiries@pacificdisplay.com.

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). 

For additional information regarding compensating the LCD contrast over your products operation range, please see the section of Pacific Display Devices website covering   LCD Temperature Compensation.


  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 Specialty Temperature Range Summary

We also offer the following custom temperature range extremes for special order LCD parts:

High Temperature Range:
Operating Temperature:  -20C to +105C
Storage Temperature: -20C to +105C

Low Temperature Range:
Operating Temperature:  -55C to +85C
Storage Temperature: -55C to +85C

These ratings only extend to 4:1 multiplexing maximum.  For additional information or information regarding other ranges available to suit your needs, please contact one of our applications engineers with your questions:  inquiries@pacificdisplay.com


  STN/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 Pacific Display Devices.

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

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

XFSTN Extended Temperature Range (-XET)
Operating Temperature:  -30C to +75C
Storage Temperature: -40C to +85C
