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.
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. .
