Plasma TVs are a type of flat-screen television that use a gas plasma technology to produce images. They consist of tiny cells filled with gas that, when electrically charged, emit ultraviolet light. This light then excites phosphors on the screen, creating vibrant colors and deep blacks, which enhance the viewing experience. These TVs are known for their wide viewing angles and excellent color accuracy, making them popular for home theaters. However, they are generally heavier and consume more power than LCD TVs. Plasma TVs have largely been replaced by newer technologies like LED and OLED displays, which offer improved energy efficiency and picture quality.
