![]() ![]() The cathode ray tube is also known as the Braun’s tube. ![]() In 1897, German Physicist Karl Ferdinand Braun invented the cathode ray tube. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'cathode-ray tube.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. The cathode ray tube is an electronic vacuum tube used for displaying electrical data in the form of images or videos on the screen. Peter Ford, The Christian Science Monitor, 9 July 2018 See More 2018 There is mercury in liquid-crystal display screens, lead in cathode-ray tubes, cadmium in semiconductors and batteries, and ozone layer-destroying chlorofluorocarbons in old refrigerators, for example. The Economist, 8 June 2019 When first built in 1965, the consoles had era-appropriate cathode-ray tube monitors. 2020 The idea of a big screen with a fixed connection will be as alien to the second half as landlines and cathode-ray tubes are to today’s youngsters. 60 An electron in a cathode-ray tube is accelerated thr. Kevin Dayhoff, /maryland/carroll, 9 Oct. 2021 Seven years later, Boris Rosing first transmitted silhouetted images of geometric shapes, using a cathode-ray tube receiver. Noah Wardrip-Fruin, The Conversation, 29 Nov. Each stream travels through a shadow mask where the electrons will impinge upon either a red, green or blue phosphor to light up a color pixel on the screen. Carina Woudenberg, Discover Magazine, Douglas created a game of tic-tac-toe, which was also displayed on a cathode-ray tube, for the University of Cambridge EDSAC computer. Most color cathode-ray tubes incorporate three electron guns, each one producing a different stream of electrons. The CRT in a computer display is similar to the 'picture tube' in a television receiver. Most desktop computer displays make use of CRTs. 2023 For example batteries need to be removed from cellphones and older, cathode-ray tube television sets require special handling due to their lead content. A cathode-ray tube (CRT) is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface. 2023 However, those retro game screens were made from cathode-ray tube (CRT), which meant when the cameras were rolling, the images were not clear. Recent Examples on the Web But the original games would have had cathode-ray tube (CRT) screens, which-as anybody using a camera back then would remember-can be difficult to capture. ![]()
