As one of the four inventors of the Liquid Crystal Display (LCD), Dr. Martin Schadt helped change how we interact with technology. In the early 1970s, Dr. Schadt, together with fellow 2012 Draper Prize winner Wolfgang Helfrich, invented the (Twisted Nematic Field Effect), which dramatically lowered the power requirements for LCDs. This opened the door for their use as a common commercial technology, and led to the thin-film transistor, developed by Peter Brody, another 2012 Draper Prize laureate. Sitting down for an interview at Draper Laboratory, Dr. Schadt discusses the path he encountered on the course to his invention.
