In liquid crystal displays (LCDs), use is made of linear polarisers, familiar to most as the glass in polarising sunglasses. If you 'cross' two polarisers (i.e. arrange them at 90 degrees to each other) then light does not pass through. This is the basis of the LCD, but between the cross polars the liquid crystals are arranged with a 'twist' Liquid crystal display - Liquid crystal display - Supertwisted nematic displays: It was discovered in the early 1980s that increasing the twist angle of a liquid crystal cell to about 180-270° (with 240° being fairly common) allows a much larger number of pixel rows to be used, with a consequent increase in the complexity of images that can be displayed Liquid Crystals: The Story Behind the Technology Did you know that liquid crystals were discovered by a botanist studying carrots? Liquid crystals, most commonly known today for their presence in liquid crystal displays (LCDs), have a molecular makeup somewhere in between a solid and a liquid. Unlike a solid, their molecules are not ordered, but unlike a liquid they do follow some structure Liquid Crystal Displays (LCDs) The first working liquid crystal display (LCD) was demonstrated at RCA in 1968. In the following year, James Fergason of Kent State University (OH) discovered the twisted nematic field effect which allowed a much higher-quality display and led to the first commercial LCD wristwatch in 1979
