Plama TV Monitors

Plasma

What is it? What is it for?

Plasma is primarily a gas made up of free flowing ions(electrically charged atoms) and and electrons (negatively charged particles). Under normal conditions, plasma gas is made up of uncharged particles (net charge of zero).

Nowadays, plasma is heavily used in science and technology for various purposes. This includes: Plasma processing(thin film deposition); Plasma-based lighting systems;Plasma chemistry; Plasma spray and bulk materials work; Sources and display systems; Environmental and health applications; One-atmosphere plasma systems; Materials synthesis; Switches, relays, focus, antennas; Power systems, thrusters.

However, the most common use we may have heard of plasma is in the television technology. In the following potion, I will discuss how plasma technology works in television monitors.

How does it work?

Plasma technology used in television monitors charge-up the plasma gas by introducing many free electrons through establishing electrical voltage. Under this conditions, the excess electrons collide with the other atoms which then knocks the other electrons off their current energy level. This creates a positive charge within the plasma atom thus attracting the “knocked-out” electrons. Simutaneosly, the positively charged atom is attracted towards the negatively charged area of the atom. Due to the various ongoing collisions, the gas atoms of the plasma are excited thereby causing them to give out photons of energy.

In a plasma display, this photons then interacts with phosphor material. This phosphor material give off light upon interaction with another light. The reaction that happens is that one of the phosphor atoms move to higher energy level and falls back simultaneously releasing a visible light photon.
