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 ...
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 ...
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.
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.
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 ...
Vladimir Kosma Zworykin[b] (1888/1889 [a] – July 29, 1982 [7]) was a Russian-American inventor, engineer, and pioneer of television technology. Zworykin invented a television transmitting and receiving system employing cathode-ray tubes. He played a role in the practical development of television from the early thirties, including charge ...
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 ...
One of the earliest electronic displays is the cathode-ray tube (CRT), which was first demonstrated in 1897 and made commercial in 1922. [1] The CRT consists of an electron gun that forms images by firing electrons onto a phosphor -coated screen. The earliest CRTs were monochrome and were used primarily in oscilloscopes and black and white ...
