(Abbreviated CRT.) A vacuum tube consisting essentially of an electron gun producing a concentrated electron beam that impinges on a phosphorescent coating on the back of a viewing face or screen. The excitation of the phosphor produces light, the intensity of which is controlled by regulating the flow of electrons. Deflection of the beam is achieved either electromagnetically by currents in coils around the tube or electrostatically by voltages on internal deflection plates.
Desktop type monitor built in the same way as a television set.
A display device used in computer monitors and television sets.
An electrical device for displaying images by exciting phosphor dots with a scanned electron beam. CRTs are found in computer monitors, televisions and oscilloscopes.
A television-like picture tube used in video terminals. See: video terminal.
A monitor that contains a vacuum tube in which a beam of electrons is projected on a fluorescent screen to produce a luminous spot. Where the spot appears on the screen is determined by the effect on the electron beam of a variable magnetic field within the tube. Synonym: Braun 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
a device that uses a beam of electrons in order to produce an image on a screen
an electron tube containing a thermionic cathode and an electron gun for the production of cathode rays which are directed axially along the tube in the direction of the flattened, wide end
(CRT) is the type of picture tube used in televisions and for computer displays.
A tube with a phosphor-treated face-plate wherein an electron beam traces an image by causing fluorescence.
(CRT) The display screen used in most televisions and standard computer monitors. An electron beam moves across the back of the screen, lighting up phosphor dots inside the glass tube, which causes an image to be displayed outside the screen.
An electron tube that has an electron gun, a deflection system, and a screen. This tube is used to display visual electronic signals. [ CRT Graphic
