Plasma televisions are flat-screen displays that use a gas called plasma to produce images. Inside the screen, tiny cells filled with this gas are electrically charged, causing them to emit light when activated. This technology allows for vibrant colors and deep blacks, making plasma TVs popular for watching movies and sports. Although plasma TVs offer excellent picture quality, they are heavier and consume more energy than other types of displays, such as LCD or LED TVs. Additionally, they can be prone to screen burn-in, where static images can leave a permanent mark on the screen if displayed for too long.
