How Plasma Televisions Are Made
Do you want to know how plasma televisions are made? Plasma televisions are made via a highly technical process. The plasma itself is a gas that is excited by electrons in order to create the image on the television. While these types of TVs are disappearing in favor of lighter and cooler LCD displays, they still have a place in many people's homes. It's a delicate process to create a plasma TV.
- The process begins with the cutting of the screen. One large sheet of glass is cut into many smaller pieces for different sizes of screens.
- Electrodes known as "bus" and "sustain" are layered onto the front glass piece. A protective coating is then layered behind them.
- Phosphorescent chemicals divided into chambers are applied to the back glass. These chemicals are the red, green and blue colors that make up color television imagery.
- The two prepared pieces of glass are now sandwiched together. Gas is pumped in that will create plasma when the electrodes heat up.
- Printed circuit boards are attached to the sandwich, now known as the plasma display. The boards tell individual pictures what it's supposed to display.
- Finished displays are sent on to the manufacturer. The manufacturer is responsible for the features that go into the finished plasma television.
All of the work is done in an ultra clean environment. One tiny speck of dust can contaminate the entire process of making the screen, requiring an entire do-over of the process. Once the plasma television has been mounted into its cabinet, quality control will perform checks to ensure that every pixel works as ordered. This guarantees that your new plasma television will work as designed directly out of the box.
