COLOR TELEVISION TUBE Meaning and
Definition
-
A color television tube refers to a cathode ray tube (CRT) used in television sets to display images in full color. It is a vacuum tube that works based on the principle of electron beams emitted from an electron gun striking a fluorescent screen coated with phosphors to produce images.
The color television tube consists of various components including an electron gun, control grid, focusing anode, deflection yoke, and a screen. The electron gun emits three electron beams – red, green, and blue – which correspond to the primary colors of light. These beams are separately controlled by the control grid to determine the intensity of each color. The focusing anode keeps the electron beams concentrated as they travel towards the screen.
Inside the color television tube, the screen is coated with tiny phosphors that emit different colors of light when excited by the electron beams. The phosphors are arranged in groups or dots called pixels, and each pixel emits red, green, or blue light depending on the intensity of the corresponding electron beam. When all three electron beams strike the screen, they combine to form various colors that make up the final image.
The color television tube revolutionized television broadcasting by enabling viewers to experience vivid and lifelike color pictures. This technology is commonly used in older television sets, while more modern designs have transitioned to flat-panel displays such as liquid crystal displays (LCD) or light-emitting diode (LED) screens.
