cathode-ray tube
a vacuum tube in which electrons from a heated cathode are focused and deflected onto a phosphorescent screen; used in television sets etc
cathode ray tube

cathode-ray tube
A cathode-ray tube is a device in televisions and computer terminals which sends an image onto the screen. Vacuum tube that produces images when its phosphorescent surface is struck by electron beams. CRTs can be monochrome (using one electron gun) or colour (typically using three electron guns to produce red, green, and blue images that, when combined, render a multicolour image). They come in a variety of display modes, including CGA (Color Graphics Adapter), VGA (Video Graphics Array), XGA (Extended Graphics Array), and the high-definition SVGA (Super Video Graphics Array)
cathode-ray tube
a vacuum tube in which a hot cathode emits a beam of electrons that pass through a high voltage anode and are focused or deflected before hitting a phosphorescent screen
