Here are a few comments from their review:
SED will have the same burn-in issues that current CRTs/Plasmas have, since it uses phosphors to display the picture. Because of this, I don't think it will be the silver bullet we all hoped.

Toshiba plans to launch a television based on a new flat-panel display technology called SED (Surface-conduction Electron-emitter Display) in 2005, a company executive says. Did this happen?
Sony and others have been working for several years on another technology called FED (Field Emission Display) but that too has yet to reach commercialization. Sony is researching FED because it is the flat-panel technology that comes closest to matching the picture of a CRT, says Makoto Kogure, vice president of Sony and president of the company's TV group. "FED's response is very fast and it's very easy to make a CRT-like picture. Power consumption is very low."
