A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. [2] The images may represent electrical waveforms on an oscilloscope , a frame of video on an analog television set (TV), digital raster graphics on a computer monitor , or ...
The cathode-ray tube amusement device was invented by physicists Thomas T. Goldsmith Jr. and Estle Ray Mann. The pair worked at television designer DuMont Laboratories in Passaic, New Jersey specializing in the development of cathode ray tubes that used electronic signal outputs to project a signal onto television screens.
Alan Archibald Campbell-Swinton FRS (18 October 1863 – 19 February 1930) was a Scottish consulting electrical engineer, who provided the theoretical basis for the electronic television, two decades before the technology existed to implement it. [1] He began experimenting around 1903 with the use of cathode-ray tubes (CRTs) for the electronic ...
Allen B. DuMont. Allen Balcom DuMont, also spelled Du Mont, (January 29, 1901 – November 14, 1965) was an American electronics engineer, scientist and inventor who improved the cathode ray tube in 1931 for use in television receivers. Seven years later he manufactured and sold the first commercially practical television set to the public.
Kenjiro Takayanagi (高柳 健次郎, Takayanagi Kenjirō, January 20, 1899 in Hamamatsu, Shizuoka – July 23, 1990 in Yokosuka) was a Japanese engineer and a pioneer in the development of television. [1] Although he failed to gain much recognition in the West, he built the world's first all-electronic television receiver, and is referred to ...
Cathode ray. A beam of cathode rays in a vacuum tube bent into a circle by a magnetic field generated by a Helmholtz coil. Cathode rays are normally invisible; in this demonstration Teltron tube, enough gas has been left in the tube for the gas atoms to luminesce when struck by the fast-moving electrons. Cathode rays or electron beams (e-beam ...
Entitled "Cathode Ray Tube Amusement Device", the patent describes a game in which a player controls the CRT's electron gun much like an Etch A Sketch. The beam from the gun is focused at a single point on the screen to form a dot representing a missile, and the player tries to control the dot to hit paper targets put on the screen, with all ...
Chromatron. The Chromatron is a color television cathode ray tube design invented by Nobel prize-winner Ernest Lawrence and developed commercially by Paramount Pictures, Sony, Litton Industries and others. The Chromatron offered brighter images than conventional color television systems using a shadow mask, but a host of development problems ...
