TFT LCD Display Work Under Extreme Environment
Does the LCD still work at the limit temperature?
Under low temperature environment, the liquid crystal(LC) will start to crystallize and flow slowly, and the color on the display will become very shallow. It is normal because of the response time of LC(physical characteristics) and that is much slower than normal temperature.
Industrial, medical devices and military sectors, among others, often require LCD displays that can operate in extreme temperature environments.
Extended / Extreme Temperature
Typically, standard LCD display provide a temperature range of 0°C to +50°C. However, this temperature range cannot always meet the needs of such usage. Considering the increasing demand of wide temperature range, several display manufacturers offer wide selection of standard versions that range from -20°C to +70°C. Extended Temperature Solutions for Industrial Applications. As a professional LCD manufacturer, we must follow more closely demands in the market. EVERVISION has developed a series of wide temperature TFT LCD modules with operating temperatures ranging from -30°C to +80°C, and the maximum for some models can reach 85°C.

Glass Heater (Transparent Heater)
Expanding the operating temperature range is one of EVERVISION's strategy to improve the performance of industrial TFT product line. The other display improvement is LCD Transparent Heater that provides optimized visual view even in an extremely low temperature environment.
Glass Heater Control Solution
As a solution, EVERVISION integrate the TFT LCD module, transparent heater(Glass Heater) and heater temperature sensor to control and monitor temperature smartly. With our controller system, it could precisely and rapidly adjust the temperature of TFT-LCD module. Also, it can reduce display power consumption.
