What happens to LCD’s when they become cold? Liquid crystal
displays are just like their name… they contain a liquid between
two layers of glass. Liquids begin to freeze as the temperature
drops. As the display freezes their response time slows down. In
other words, it takes longer for the numbers and letters on the
display to change (Turn ON or Turn OFF). Above is a graph
showing the response time of a display at -30°C (-22°F). The
best way I can think to explain this is a ceiling fan. When you
turn off the ceiling fan the blades continue to turn for a few
minutes, even though the power if OFF. When you turn ON a
ceiling fan the blades will be at full speed in a shorter period
