A color CRT contains three electron guns that shoot electron beams, causing red (R), green (G), or blue (B) phosphors on the inside front of the screen to light up.
A device in the back of a TV tube that generates negatively charged particles—electrons—and shoots them at the phosphor dots imprinted on the front of the screen. Inside the electron gun, there's a cathode, or negatively charged piece of metal, to generate the electrons and to send them speeding toward the front of the tube; and a system of electromagnets, called a "deflection yoke," to guide them accurately toward the individual phosphor dots.
the electrode that is the source of electrons in a cathode-ray tube or electron microscope; consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it
The part in the CRT that produces the electron beam that is attracted to the phosphor-coated back surface of the screen. The beam strikes the phosphors, causing them to emit red, green, or blue light, creating visual images on the screen.
The device used to project an image inside a cathode ray tube. Color monitors have three guns (red, green and blue).
Device in a conventional television (CRT) tube from which electrons are emitted toward the screen.
An electrode of a CRT that is equivalent to the cathode and control grid of conventional tubes. The electron gun produces a highly concentrated stream of electrons.
The device in the CRT that produces the electron beam that activates the phosphors, causing them to emit red, green and blue light.
n. A device that produces an electron beam, typically found in television or computer monitors. See also CRT.
An electron gun is a component that produces an electron beam that has a precise kinetic energy, being used in all TVs and monitors which use cathode ray tube technology, and in other instruments, eg. electron microscopes and at the beginning of linear particle accelerators.
