High voltage is only dangerous because it can enable large amounts of current to flow through your body (assuming large amounts of current are available), the current is what actually kills you. The IC that drives the display is only capable of driving 1 mA which is only barely at the threshold of perception and not in any way dangerous.

Freezing / boiling point of pure water at sea level. It's a fine way to define a measurement scale, but there are several arbitrary decisions in there. Why water? Why not salt water at ocean-average saltiness? Why sea level? Arbitrary. Convenient perhaps if you're working with scientific applications where 1 atmosphere or pressure is a commonly defined unit, but still arbitrary. Fahrenheit is also arbitrary. It's also perhaps more convenient when dealing with air temperatures. 100 = "It's really hot out there", 0 = "It's really cold out there".
