Editorial review board...

[Pete Deksnis]

Didn't know SED from MUD till I read a news report this morning. Wrote up a little bit on the CT-100 site. Sounds like an advanced 15G to me. Corrections/more detail?

"Forget plasma, LCD, and even DLP.

Is the future of high-definition
flat-screen TV just
a variation of the first color CRT?

SED is the future darling of the big-, flat-, wide-screen TV industry because SID images are just as sharp as the traditional cathode ray tube. [IMO, the direct-view delta-gun CRT computer monitor still produces the best high-resolution consumer video image.]

SED stands for Surface-conduction Electron-emitter Display, and it is very similar to CRT technology. It generates a picture when electrons collide with a phosphor-coated screen. But instead of using three electron guns, SED technology employs a large array of tiny electron guns; SID calls them emitters -- one for each pixel on the display.

Of course, tricolor CRTs beam electrons from the back of the bottle, but SED emitters are on a plate located extremely close to the phosphor-coated faceplate. That means a much slimmer TV can be built with a much larger viewing area than is possible with CRT technology.

Toshiba may have a 55-incher on the market in 2006.

The future of high-quality flat-screen video may just be a variation of the venerable 15GP22."

From what I've heard, those sharp points get dull rather quickly and stop emmitting electrons after a while.

Boy, I thought I kept my ear to the ground and I had never hear of that one! Another good day... I ended it a little less ignorant than I started it!

I confess... I don't understand the reference to "Editorial review board"?

Just a call for comments and/or more information on the subject of SED's, which are new to me, as it relates to the accuracy of the quoted piece that originated on my site here at the bottom of this link:

Here is Canon's web page on the technology. Canon is the developer along with Toshiba.

Wait a minute. If these guys actually come out with SED, and there's an 8-1/2x11 panel, why couldn't we pop one in a dud 15GP22! Best of the vintage and latest technology. All we need then is a black box: I, Q, Y in to SED out? Or maybe the decoder's already built in?

Scheme like that though could be akin to fish-tanking a CTC-5 cabinet.

plus you would need to add some software changes to it to add some reaslistic mis-convergence, lack of comb filter, etc ; )

Assuming SED displays are under vacuum like CRTs, I wonder what the limit is as far as how large they could be.

[Pete Deksnis]

Dug up the original SED info while surfing the TVPredictions.com Newsletter Swanni Sez! the other day. In it they were speculating whether manufacturing SED panels the size of today's large plasma screens would prove to be feasible. And as mentioned earlier, a 55-incher is due 'soon'... I hope so.

CNET has posted some interesting threads on SED and FED technology:

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.

This was published by Martyn Williams, IDG News Service over a year ago on Monday, December 06, 2004:

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."
