In order for a display to work instantly and consistently within a hostile environment, several technologies need to be brought together to work in parallel to get the best performance. These include the liquid crystal mixture itself, the operating heat threshold of the backlight which can be prone to fail at high temperatures, the size and power draw of the heater for extreme cold temperatures and ultimately the capability of any supplier to integrate all of these technologies seamlessly. Lumex is able to bring all of these technologies together into a single integrated solution with either standard or custom displays.
