Important factors to consider when evaluating an LCD monitor include resolution, viewable size, response time (sync rate), matrix type (passive or active), viewing angle, color support, brightness and contrast ratio, aspect ratio, and input ports (e.g. DVI or VGA). Pioneering work on liquid crystals was undertaken in the late 1960s by the UK's Radar Research Establishment at Malvern. The team at RRE supported ongoing work by George Gray and his team at the University of Hull who ultimately discovered the cyanobiphenyl liquid crystals (which had all of the correct stability and temperature properties for application in LCDs). Active matrix technologies MVA
A general purpose alphanumeric LCD, with two lines of 16 characters. IPS (In-Plane Switching) was developed by Hitachi in 1996 to improve on the poor viewing angles and color reproduction of TN panels. These improvements came at a loss of response time, which was initially on the order of 50ms. IPS panels were also extremely expensive. Twisted Nematic (TN) A Color LCD is a descendant of the primative monochrome LCD. This kind of LCD can emulate almost any real-life image compared to a monochrome LCD.

The glass panels seem to be vacuum sealed, because when they are broken,the plasma breaks up,seemingly from the addition of air to the space. The xenon and neon gas in a plasma television is contained in hundreds of thousands of tiny cells positioned between two plates of glass. Long electrodes are also sandwiched between the glass plates, on both sides of the cells. The address electrodes sit behind the cells, along the rear glass plate. The transparent display electrodes, which are surrounded by an insulating dielectric material and covered by a magnesium oxide protective layer, are mounted above the cell, along the front glass plate.

1936: The Marconi Wireless Telegraph company patents the first practical application of the technology, "The Liquid Crystal Light valve". 1904: Otto Lehmann publishes his major work "Liquid Crystals" Months after the release of the Nintendo Game Boy which had crude monochrome graphics on an LCD without backlight, Atari and Epyx released the Atari Lynx, which was the first handheld game console with interchangeable cartridges to have a backlit color LCD. Subsequent to the Lynx's release, the Sega Game Gear which also had a backlit color LCD was released. However, the Atari Lynx didn't have familiar titles like the Game Gear, and advertisements for the Game Gear claimed "Nintendo dosen't do what Sega does" hence the color graphics on the Game Gear. People however thought that those ads were offensive even though the Game Boy had crude monochrome graphics. Game consoles with color LCDs would not have critical success until the rise of the Gameboy Color. Zero-power displays General characteristics
