History

Braun HF 1, Germany, 1959

In television's electromechanical era, commercially made television sets were sold from 1928 to 1934 in the United Kingdom,^[1] United States, and Russia. ( German pronunciation "brown" commonly pronounced "brawn" in English GmbH is a German consumer products company in Kronberg im Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. The Television Technology can be divided along two lines those developments that depended upon both mechanical and electronic Principles and ^[2] The earliest commercially made sets sold by Baird in the UK in 1928 were radios with the addition of a television device consisting of a neon tube behind a mechanically spinning disk (the Nipkow disk) with a spiral of apertures that produced a red postage-stamp size image, enlarged to twice that size by a magnifying glass. Neon (ˈniːɒn is the Chemical element that has the symbol Ne and Atomic number 10 A Nipkow disk (sometimes Anglicized as Nipkov disk also known as scanning disk, is a mechanical geometrically operating Image scanning device invented by The Baird "Televisor" was also available without the radio. The Televisor sold in 1930–1933 is considered the first mass-produced set, selling about a thousand units. ^[3]

The first commercially made electronic television sets with cathode ray tubes were manufactured by Telefunken in Germany in 1934,^[4][5] followed by other makers in France (1936),^[6] Britain (1936),^[7] and America (1938). The cathode ray tube (CRT is a Vacuum tube containing an Electron gun (a source of electrons and a Fluorescent screen with internal or Telefunken is a German radio and television company founded in 1903 in Berlin, as a joint venture of two large companies Siemens & Halske (S & H and ^[8][9] The cheapest of the pre-World War II factory-made American sets, a 1938 image-only model with a 3-inch (8 cm) screen, cost US$125, the equivalent of US$1,863 in 2007. The United States dollar ( sign: $; code: USD) is the unit of Currency of the United States; it has also been The United States dollar ( sign: $; code: USD) is the unit of Currency of the United States; it has also been The cheapest model with a 12-inch (30 cm) screen was $445 ($6,633). ^[10]

An estimated 19,000 electronic television sets were manufactured in Britain, and about 1,600 in Germany, before World War II. About 7,000–8,000 electronic sets were made in the U. S. ^[11] before the War Production Board halted manufacture in April 1942, production resuming in August 1945. The War Production Board ( WPB) was established as a government agency on January 16 1942 by executive order of Franklin D

Television usage in the United States skyrocketed after World War II with the lifting of the manufacturing freeze, war-related technological advances, the gradual expansion of the television networks westward, the drop in set prices caused by mass production, increased leisure time, and additional disposable income. World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including While only 0. 5% of U. S. households had a television set in 1946, 55. 7% had one in 1954, and 90% by 1962. ^[12] In Britain, there were 15,000 television households in 1947, 1. 4 million in 1952, and 15. 1 million by 1968.

Components

Modern television sets consist of a display, antenna or radio frequency (RF) input (usually an F connector), and most significantly a television tuner which distinguishes it from a monitor which receives signals that are already processed. A display device is an Output device for presentation of Information for Visual or Tactile reception acquired stored or transmitted An antenna is a Transducer designed to transmit or Receive electromagnetic waves In other words antennas convert electromagnetic waves into The F connector is a type of coaxial RF connector commonly used for "over the air" Terrestrial television Additionally TV sets almost always include speakers. Most TV sets also feature many additional inputs for devices such as DVD players, video game consoles, and headphones; the most common types are RCA (for composite and component video), mini-DIN (for S-Video), HDMI, and SCART and D-terminal can be found in Europe and Japan respectively.

An RCA jack, also referred to as a phono connector or CINCH/AV connector, is a type of Electrical connector that is commonly used in the audio/video The mini-DIN connectors are a family of multi-pin Electrical connectors used in a variety of applications The High-Definition Multimedia Interface ( HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams SCART (from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) This article is about the video connector For the item used in Digimon Adventure 02, see Digivice. Most TV sets made since the early 1980's also feature an infrared sensor in order to detect the signals sent by remote controls. A remote control is an electronic device used for the remote operation of a Machine.

Display Technologies

Sony 11-inch OLED, released in Japan at the end of 2007

Televisions today use various display technology such as CRT, LCD, Plasma, DLP, and more recently OLED. The cathode ray tube (CRT is a Vacuum tube containing an Electron gun (a source of electrons and a Fluorescent screen with internal or A plasma display panel (PDP is a type of Flat panel display now commonly used for large TV displays (typically above 37-inch or 940 mm Digital Light Processing (DLP is a Trademark owned by Texas Instruments, representing a technology used in projectors and Video projectors It was An Organic Light Emitting Diode ( OLED) also Light Emitting Polymer ( LEP) and Organic Electro Luminescence ( OEL) is any Some front projectors, which feature TV tuners, can also be considered televisions.
