Typically, standard LCD modules provide a temperature range of -20°C to +70°C. To meet the need of customers, 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.

EVERVISION developed LCD Heater to integrate with our TFT Display Module so that can show optimal view even in low temperature. For materials, heaters can be used with transparent resins, such as glass and poly-carbonate. Our LCD Transparent Heater is made of glass substrate, so we name it “Glass Heater”. It can not only improve the LCD image sticking issue efficiently, but also have heat and humidity resistance advantage.

While directly current flows in ITO"s resistance, it will turn electrical energy into heat. The smaller resistance is (the higher consumption power is), the more heat it can generate. The concept is similar to Traveling immersion coil. When we plug in Traveling immersion coil, the current will flow in metal and generate heat to boil water.

As the result, it shows 4.3 inch TFT LCD Module display functionally under normal operating conditions. However, there is an overlapping at low temperature, because of LC"s physical characteristics. From this experiment, we know that overlapping can be solved by turning on Glass Heater.
