A plasma screen or plasma display is a television, usually larger, ranging from 40-inches to 65-inches. Other sizes may be available but are less common. Plasma screens are similar to LCD (liquid-crystal display) and LED (light-emitting diode) televisions in that they are flat-panel, thin, and can be mounted on a wall.
How does a plasma screen work?
A plasma screen is made up of many tiny cells containing noble gases and a tiny amount of mercury. These cells are between two pieces of glass, and electricity is passed through the cells, causing the gases to turn into plasma. Light is then emitted, generating a picture on the screen.
Advantages of a plasma display
Plasma screens have multiple advantages:
- Support higher resolutions up to 1920 x 1080.
- Excellent contrast ratio.
- Wide viewing angle.
- High refresh rate that reduces video blur.
Overall, plasma screens are excellent for fast-action movies and sports games and provide an excellent viewing experience.
Disadvantages of a plasma display
Plasma screens also have several disadvantages:
- Increased chance of screen burn-in.
- Loss of brightness over time.
- Higher cost of use (higher electricity use).
- Bulky and heavier.
- Ten-year lifespan.
Are plasma screens still used today?
In July 2014, Samsung announced that it was ending its plasma TV development later that year. Panasonic announced soon after that they were also ending their plasma TV development. Today, plasma TVs are not used much anymore and are becoming a thing of the past.
