For certain extreme applications like military. Marine or some outdoor applications, a wide range temperature solution is required to survive the environment.
Those applications exposed to direct sunlight can lead the surface of the LCD display as much high as +55°C to +60°C, and even worse with temperature fluctuations.
The water-proof requirement and heat generated by the LCD panel and the electronics in combination with heat caused by solar energy make the outdoor application a extreme harsh environment for the LCD Monitor / PC.
Winsonic provides rugged LCD displays / PC solution for those extreme environments. The wide temperature requirement can range from -30 °C to +60°C or even more extreme.
