plasmapaneler

A plasmapanel is a type of flat panel display technology that uses small cells containing ionized gas, or plasma, to produce light. Each cell is typically located between two glass panels and contains a mixture of noble gases such as neon and argon. When an electrical voltage is applied to electrodes within the cell, the gas becomes ionized and forms a plasma. This plasma then emits ultraviolet (UV) light. This UV light strikes a layer of phosphors on the inside of the front glass panel, causing them to glow and produce visible light. Different colors are produced by using different types of phosphors, similar to cathode ray tube (CRT) televisions.

Plasmapanels were a popular choice for large-screen televisions from the late 1990s through the early 2010s. They were known for their excellent black levels, wide viewing angles, and fast response times, making them ideal for watching movies and sports. However, they also had some drawbacks, including higher power consumption compared to some other display technologies, a susceptibility to "burn-in" if static images were displayed for extended periods, and a tendency to be heavier and thicker than competing LCD panels. Manufacturing costs also contributed to their price.

While once a dominant technology, plasmapanels have largely been replaced in the consumer market by newer technologies like LED-backlit LCDs and OLED displays, which offer improved energy efficiency, thinner designs, and higher resolutions. However, the fundamental principles of plasma display technology continue to be explored and may find applications in specialized fields.
