The history of LCD monitors

History

1888: The liquid crystalline nature of cholesterol was discovered by Friedrich Reinitzer. It was extracted from carrots which was generation of colours. He published the findings on May 3, 1888 at a meeting of the Vienna Chemical.

1904: “Flüssige Krystalle” (Liquid Crystals), which was Otto Lehmann’s work, was published

1911: The first experiment of liquids crystals of Charles Mauguin was confined between thin layers and plates.

1922: The properties and structure of liquid crystals were divided into 3 types (cholesterics, nematics and smectics), described by George Friedel

1936: “The Liquid Crystal Light Valve”, the first practical application of the technology was patented by the Marconi Wireless Telegraph company.

1962: Electro-optic characteristics contained in the liquid crystals were discovered by Richard Williams who later realised an electro-optical effect when he generated stripe-patterns of liquid crystal material in a thin layer by the application of a voltage. The effect is related to an electro-hydrodynamic instability forming which is known as “Williams domains”.

1964: George H. Heilmeier, who worked in the RCA laboratories on the electro-optical effect found by Williams discovered the change of colours by field-induced realignment of dichroic dyes in an oriented liquid crystal. Heilmeier kept on working on the effects in liquid crystals due to some problems with the effect and he later realised that the first operational liquid crystal display was relevant to the dynamic scattering mode (DSM).

1960s: The UK’s Royal Radar Establishment was the first pioneer who worked on liquid crystals which were undertaken at Malvern in the late 1930s.

1970: Hoffmann-LaRoche patented the twisted nematic field effect in liquid crystals in Switzerland with Martin Schadt and Wolfgang Helfrich who were considered inventors.

1972: T. Peter Brody produced the first active-matrix liquid crystal display panel in the United States

2007: CRT was first surpassed by LCD in worldwide sales in the 4th Quarter of 2007.

2008: According to Display Bank, LCD TVs have 50% market share of the 200 million TVs forecast
