LCD Temperature Ranges

Blaze Display Technology Co., Ltd. | Updated: Oct 28, 2015

    【R&D Department of Blaze Display】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 effected 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.

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. The following parameters are for general reference.

    
TN Standard Temperature Range

Operating Temperature: -10°C to +60°C
Storage Temperature: -20°C to +60°C

    TN Wide Temperature Range

Operating Temperature: -30°C to +80°C
Storage Temperature: -40°C to +80°C

    There are also specially designed TN LCD that operates at an especially higher temperature (-20 to 105) or lower temperature (-55 to 85).

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 standard products.

    STN/FSTN Standard Temperature Range

Operating Temperature: 0°C to +50°C
Storage Temperature: -10°C to +60°C

    STN/FSTN Wide Temperature Range

Operating Temperature: -20°C to +70°C
Storage Temperature: -30°C to +80°C
