It has been suggested that Color LCD be merged into this article or section. ...


After obtaining a Bachelor's Degree in physics from the University of Missouri in 1956, Fergason began his work on the practical uses of liquid crystals at the Westinghouse Research Laboratories in Pennsylvania, earning his first patent (U.S. Patent 3,114,836) in 1963. In 1968, Fergason earned another patent for a liquid crystal display that utilized the twisted nematic field effect of liquid crystals. These displays were far superior to the earlier dynamic scattering display, and soon became the standard. The examples and perspective in this article or section may not represent a worldwide view. ... Physics (from the Greek, φυσικός (physikos), natural, and φύσις (physis), nature) is the Science of Nature. ...

Two years later, he left Westinghouse and formed his own company, ILIXCO, to manufacture these improved liquid crystal displays. His first customer was the Gruen watch company of Switzerland, which used the technology to market the first LCD watches using this technology. By the end of the decade, most of the world's digital watches used this kind of LCD display. LXD, Incorporated is one of the first Liquid Crystal Display Manufacturers in the world. ...


Today, Fergason holds over 150 patents in the United States and over 500 foreign patents. He also has been recently inducted into the National Inventors Hall of Fame. In 2001, he founded Fergason Patent Properties, which managed licensing of his patents. The National Inventors Hall of Fame is an organization that honors important inventors from the United States. ... 2001: A Space Odyssey. ...

Liquid crystal display pioneer honored - Boston.com (416 words)
James Fergason, who helped pioneer liquid crystal display technology used in everything from computer monitors to mood rings, is this year's winner of the $500,000 annual Lemelson-MIT Prize.
Fergason was scheduled to receive the United States' largest single cash award for invention during a private ceremony Wednesday in Chicago.
Fergason observed that liquid crystals are naturally twisted, but could be untwisted with an electric current.
