Liquid-Crystal Display, 1968

Liquid Crystal Display.jpg

Between 1964 and 1968, at the RCA David Sarnoff Research Center in Princeton, New Jersey, a team of engineers and scientists led by George H. Heilmeier with Louis A. Zanoni and Lucian A. Barton, devised a method for electronic control of light reflected from liquid crystals and demonstrated the first liquid crystal display. Their work launched a global industry that now produces millions of LCDs annually for watches, calculators, flat-panel displays in televisions, computers and instruments.

The plaque can be viewed at SRI International, 201 Washington Road, Princeton, NJ 08540 USA; GPS: 40.33146, -74.63136. The plaque is one of three that are mounted on the left and right pillars adjoining the entrance doors to the Visitors Lobby. This facility was formerly the David Sarnoff Research Center and later Sarnoff Corp.
