A plasma TV, also known as a plasma display panel (PDP), is a type of flat-panel television technology that was popular in the early 2000s. Plasma TVs use a combination of noble gases (such as xenon and neon) and tiny cells filled with phosphors to create images on the screen.
Each pixel in a plasma display consists of three sub-pixels: red, green, and blue. These sub-pixels are individually controlled to produce the desired colors and brightness levels. When an electric current is applied to the gas in the cells, it ionizes and emits ultraviolet (UV) light. The UV light then causes the phosphors to emit visible light, resulting in the formation of images.
Plasma TVs were known for their deep black levels, excellent color accuracy, and wide viewing angles. They were capable of displaying rich and vibrant colors, making them popular among home theater enthusiasts. However, plasma TVs also had some drawbacks. They were heavier, consumed more power, and were more prone to screen burn-in compared to other display technologies.
In recent years, plasma TVs have become less common in the market. The popularity of plasma displays declined as LCD (liquid crystal display) and later LED (light-emitting diode) TVs became more affordable, energy-efficient, and offered comparable picture quality. As a result, most manufacturers phased out plasma TVs from their product lineups, and the focus shifted towards LCD and LED technologies.
