A CRT TV, short for cathode-ray tube television, is an older type of television that uses a large, heavy glass tube to display images. It works by shooting an electron beam onto a phosphorescent screen, which lights up to create pictures. CRT TVs were widely used before flat-screen TVs became common and were known for their durability and good color quality. However, they were bulky, heavy, and limited in screen size compared to modern LCD, LED, and OLED TVs, which are thinner, lighter, and provide better image quality.
