See all on Wikipediahttps://en.wikipedia.org/wiki/Liquid-crystal_displayA liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or … See more
Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of Indium-Tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the … See more
Since LCDs produce no light of their own, they require external light to produce a visible image. In a transmissive type of LCD, the light … See more
A standard television receiver screen, a modern LCD panel, has over six million pixels, and they are all individually powered by a wire network embedded in the screen. The fine … See more

Twisted nematic displays contain liquid crystals that twist and untwist at varying degrees to allow … See moreThe origins and the complex history of liquid-crystal displays from the perspective of an insider during the early days were described by Joseph A. Castellano in Liquid Gold: The … See more
Monochrome and later color passive-matrix LCDs were standard in most early laptops (although a few used plasma displays ) and the original … See more
Some LCD panels have defective transistors, causing permanently lit or unlit pixels which are commonly referred to as stuck pixels or dead pixels respectively. Unlike integrated circuits (ICs), LCD panels with a few defective transistors are usually still usable. … See more

In 1888, Austrian botanical physiologist Friedrich Reinitzer, working at the Karl-Ferdinands-Universität, examined the physico-chemical properties of various derivatives of cholesterol which now belong to the class of materials known as cholesteric liquid crystals. Previously, other researchers had observed distinct color effects when cooling cholesterol derivatives just above the freezing point, …

- A thin-film-transistor liquid-crystal display is a variant of a liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments. TFT LCDs are used in appliances incl...

Active-matrix liquid-crystal display - Wikipedia
https://en.wikipedia.org/wiki/Active-matrix_liquid-crystal_displayAn active-matrix liquid-crystal display is a type of flat-panel display, the only viable technology for high-resolution TVs, computer monitors, notebook computers, tablet computers and smartphones with an LCD screen, due to low weight, very good image quality, wide color gamut and response time. The concept of active-matrix LCDs was proposed by Bernard J. Lechner at the RCA …
