This also happens when the panels get older. At last report, the Army had a three foot by three foot panel constructed for high-altitude / high-resolution applications. I don't know how many pixals wide and high it was, but I imagine it was either 1024x1024 or 2048x2048. Additionally, several japenese companies (Nippon Bell is one, I think) are getting into the plasma panel market. They are trying to get color plasma panels to work, as well as develope other fast panels. The color panels work by putting posphores where the dots light up and using that energy to excite the phosphore (or so they said). The "fast" panels they were working on at the time they came and talked to us were called "shift panels" -- they were slightly different in design from the standard panel. They create an image at the far right on a 16 pixal tall space and then "shift" it over to where it should be. This causes some really strange effects and seems to only be very useful for alphanumerics or customized character sets. Their main advantage is that they are much flatter than normal plasma panels and it would be practical to make a plasma based TV.
