Plasma Display Panel Characterization Using Spectroscopic Ellipsometry

Plasma Cell Cross Section of a Typical PDP.

Plasma Cell Cross Section of a Typical PDP.

Plasma is the state of a matter where atoms are ionized by adding energy. In the context of plasma display technology, a plasma display is a computer video display in which each pixel on the screen is illuminated by a tiny bit of plasma or charged gas, very similar to the way that a fluorescent or neon light works.

The plasma display technology demonstrates inherent engineering advantages over conventional CRTs (Cathode Ray Tubes) and LCD (Liquid Crystal Display) panels. Plasma displays are thinner than a CRT and brighter than LCD panel. They also offer a very wide viewing angle that is free from distortion at the edges of the screen.

For multilayer structures it is always helpful and often necessary to know the properties of each film. Using the Jobin Yvon UNISEL NIR it is a straightforward procedure to investigate the thickness and optical properties of the complete PDP structure.

To ensure high yields in quality and quantity the FF-1000 ellipsometer is dedicated to the flat panel industries with a fully automated large area sample stage able to accept samples up to 1000 mm x 1000 mm.

This accurate, automated thin film metrology tool delivers both unique performance and proven reliability for online quality control of production processes.
