A plasma screen is a type of flat-panel display technology commonly used in televisions and computer monitors. It works by using small cells filled with gas that emit ultraviolet light when electrically charged. This light then excites phosphors, producing vibrant colors and images on the screen. Plasma screens are known for their excellent color accuracy and wide viewing angles, making them popular for home entertainment. However, they are generally heavier and consume more power than other display types, such as LCD or LED screens. Despite this, they offer a unique visual experience, especially for watching movies and sports.
