There is a growing global demand for user interface technology that can perform in extreme cold and extreme heat conditions. Applications as diverse as aircraft auxiliary power units, commercial freezers, retail and industrial gas pumps, fuel meters, portable emergency respiratory care and non-climate controlled facilities require accurate displays able to perform consistently in even the most challenging of environments. LCDs designed into these types of applications must meet a host of demanding challenges, such as shock and vibration, varying lighting conditions and extreme temperature changes.
