What is inside a computer monitor?
The technology of displays have evolved as computer technology continues to advance along with consumer demands for new and engaging media that test the senses. Features vary by manufacturer, but there are certain devices critical to CRT and LCD monitors.Cathode-Ray TubeCathode-ray tube (CRT) monitors are named for the bulbous vacuum tube that dominates the space of the monitor and the cathode ray that fires electrons at the screen.Vacuum TubeThe glass bulb that makes up the shell of the CRT maintains a vacuum to prevent interference with the fired electrons. The screen, the part of the tube that faces the user, bears a phosphorescent coating that lights up with color when hit with electrons. The coating is on inside of the tube for its protection.Electron GunElectricity powering the monitor heats up a filament that acts as the ammo for the electron gun. Negatively charged electrons are drawn to anodes, electrodes that direct current flow. The electrons are steered into three beams tha
