How Does CRT Television Work?

CRT television technology is founded on the principles of electron beams and phosphorescent screens. At its core, a CRT television uses a cathode ray tube to display images by firing electron beams at a phosphorescent screen. The tube consists of a vacuum-sealed glass envelope with a cathode at one end and a screen at the other. When the television is turned on, the cathode heats up and emits electrons, which are then focused and accelerated towards the screen by an anode.

The screen of a CRT television is coated with phosphorescent materials that glow when struck by the electron beams. By controlling the intensity and direction of the beams, the television can create a wide range of colors and images. The electron beams are deflected using magnetic fields generated by deflection coils, allowing them to scan across the screen in a pattern known as a raster scan. This process occurs rapidly, with the beams scanning the entire screen multiple times per second to produce a continuous image.

CRT televisions rely on three electron guns, each corresponding to one of the primary colors: red, green, and blue. By varying the intensity of each electron beam, the television can produce a full spectrum of colors. The combination of these colors creates the images we see on the screen.
