Plasmanäytöiden

Plasmanäytöt, often referred to as plasma displays, are a type of flat-panel display technology that generates light using small cells containing plasma. Each of these cells acts as a tiny fluorescent lamp. When an electric voltage is applied to the electrodes within a cell, the gas inside becomes ionized, forming a plasma. This plasma then emits ultraviolet light, which in turn excites phosphors coating the back of the cell. These phosphors then emit visible light, creating the image on the screen.

Plasma displays were a popular choice for televisions in the early 2000s, known for their deep black levels, excellent contrast ratios, and wide viewing angles. Unlike early LCD technology, plasma panels could achieve very high refresh rates, which made them ideal for displaying fast-moving content like sports and action movies without motion blur. The technology offered vibrant colors and a realistic picture quality that many consumers appreciated.

However, plasma displays also had some drawbacks. They were generally thicker and heavier than competing LCDs, and they consumed more power. Early models could also suffer from "burn-in," where static images displayed for extended periods could leave a permanent ghost image on the screen, although this issue was significantly reduced in later generations. Despite their advantages, the manufacturing process for plasma panels was complex and costly, and the increasing efficiency and decreasing cost of LCD and later OLED technologies eventually led to the decline and discontinuation of plasma display production.
