An active-matrix liquid-crystal display (AMLCD) is a type of flat-panel display used in 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 fast response time.
Information on two types of flat-panel display at the Zürich Hauptbahnhof railway station: an orange LED display (top right) and a LCD screen (bottom) A flat-panel display (FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment.
Westinghouse Electronics, LLC is a Chinese-owned American company that manufactures LCD televisions located in Diamond Bar, California. [ 1 ] It is a licensee of the Westinghouse Licensing Corporation , commonly known as Westinghouse Electric Corporation.
[4] [5] Brody and Fang-Chen Luo demonstrated the first flat active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975. [ 3 ] By 2013, most modern high-resolution and high-quality electronic visual display devices used TFT-based active matrix displays.
Canon began SED research in 1986. [5] Their early research used PdO electrodes without the carbon films on top, but controlling the slit width proved difficult. At the time there were a number of flat-screen technologies in early development, and the only one close to commercialization was the plasma display panel (PDP), which had numerous disadvantages – manufacturing cost and energy use ...
This is the estimated time over which maximum picture brightness degrades to half the original value. [55] Plasma screens are made out of glass, which may result in glare on the screen from nearby light sources. Plasma display panels cannot be economically manufactured in screen sizes smaller than 82 centimetres (32 in).
The 2011 UEFA Champions League Final match between Manchester United and Barcelona was broadcast live in 3D format in Gothenburg (Sweden), on an EKTA screen. It had a refresh rate of 100 Hz, a diagonal of 7.11 m (23 ft 3.92 in) and a display area of 6.192×3.483 m, and was listed in the Guinness Book of Records as the largest LED 3D TV.
several picture elements have common electrical connections to the driving electronics, e. g.. row and column electrodes when the picture elements are arranged in a two dimensional matrix. active matrix addressing active electronic elements added in order to improve selection of picture elements. thin-film diodes (TFDs) thin-film transistors (TFTs)
