Yep, but prototypes of (small, monochrome) LCD screens were created in the '60's, your $50,000 data point would have been probably mid-1980's, and the $100 lcd tv's probably happened in the late 2010's. I wouldn't be surprised (if this humidity device actually works and can be bettered) that working regrigerator sized units will be availably in 2040 and be actually affordable by the 2070's.
