Design Process for Plasma TV

In the Beginning

The process of designing a plasma television begins with glass sheets. Usually, six 42-inch and four 50-inch panels are cut from the original sheet.

The Chemical Component

The two sheets of glass then "sandwich" a gas that converts electrical signals into luminescent plasma creating visible light. Intense electrical voltage is sent through bus electrodes and sustain electrodes to produce the plasma. On top of the rear glass sheet, red, green and blue incandescent chemicals coat various chambers to produce the colors you see on the television. An address electrode then serves as a switch because the plasma creates ultra-violet light producing varying colors.

The Human Component

Engineers operate robots via computer to print phosphorescent chemicals on the rear substrate of the LCD panel. Printed circuit boards are added to display panels, sending a signal to each pixel. Television manufacturers add signal receivers, control panels and covers. Once quality control checks each set, they're ready for sale.
