What is a CRT TV and how does it work?
A CRT (Cathode Ray Tube) TV is an older type of television that uses a cathode ray tube to display images. It works by shooting beams of electrons onto a phosphorescent screen, creating the images that we see. The CRT is essentially a large vacuum tube that contains an electron gun, a phosphorescent screen, and a magnetic field that controls the direction of the electron beams.
The electron beams are scanned horizontally and vertically across the screen, creating a pattern of red, green, and blue phosphors that combine to produce a color image. The magnetic field is used to focus the electron beams and ensure that they hit the correct phosphors, creating a sharp and clear image. While CRT TVs were once the standard for television technology, they have largely been replaced by newer technologies such as LCD and LED TVs.
