Cathode Ray Tube
A cathode-ray tube (CRT) is an older technology used in devices like televisions and computer monitors. It consists of a vacuum tube that contains a beam of electrons emitted from a cathode, which is then directed towards a phosphorescent screen. When the electrons hit the screen, they light up, creating images. CRTs were popular for many years due to their ability to produce rich colors and deep blacks, but they have largely been replaced by flat-panel displays like LCDs and LEDs due to their bulkiness and energy consumption.

A Cathode Ray Tube (CRT) is a technology used in older televisions and computer monitors. It consists of a large glass tube that contains a vacuum and an electron gun at one end. The electron gun shoots beams of electrons toward the screen, which is coated with phosphorescent material. When the electrons hit the screen, they light up to create images. CRTs were popular for many decades due to their ability to display rich colors and deep contrasts, but they have largely been replaced by flat-panel technologies like LCD and LED due to their bulkiness and lower energy efficiency.

A cathode ray tube (CRT) is a technology used in older televisions and computer monitors. It works by firing electrons from a heated cathode through a vacuum inside a glass tube. These electrons strike a phosphorescent screen at the front of the tube, creating visible images by lighting up in different colors. The screen is coated with phosphors that glow when hit by the electrons. Though largely replaced by modern flat-screen technologies like LCD and LED, CRTs were once the standard for displaying video due to their ability to produce clear and vibrant images.
