Toshiba and Canon showcase 36-inch SED display

Posted on Tuesday, September 06 2005 @ 2:56 CEST by Thomas De Maesschalck

Toshiba has developed a prototype of a SED display in cooperation with Canon. The prototype was displayed at the IFA show in Berlin and the companies claim this technology combines the image quality and the response times of CRT displays with the thin profile of LCD and Plasma displays.

The company says a SED (Surface-Conduction Electron-Emitter Display) uses a mini-electron cannon for each pixel and claim a SED display consumes three times less energy than LCD displays.

At the IFA show a 36-inch SED display was showcased behind closed doors and according to our sources the image quality was really impressive. The companies hope to release a 50-inch display by Spring 2006.

Mass production of SED displays is expected for 2007 and the companies hope SED will dominate the market of displays larger than 40-inch by 2010.

Carbon Nano Tube displays have been promised to be on shelves for the last 2 years now.

motorolla claimed Nano Emissive Display (NED) technology would enable 40inch HDTV, thinner than LCD, better quality imagery than CRT with similar/better contrast, viewing angle etc. at a manufacturing cost of only $400 usd.

so....
anyone know how CNT and SED compare, tech and price wise?

The cost of these screens will be massive compared to any current LCD or Plasma set. I would be surprised if anyone thought the improvement in image quality would justify the 2 - 3x price premium of an SED set over a nice HD Plasma for example.

The pursuit of perfection in image quality is a good thing, but at some point when you are sitting around 2m or more from the display, that marginal increase in IQ is not worth the additional thousands of dollars it takes.

That means SED will remain unviable as a mass-consumer product until 2009-10. And even then I'd say LCD will still be dominant at that point due to price drops.

Motorola have been pretty adamant about that cheeper thana plasma/LCD to manufacture thing, though there will probably be a premium for new tech it shouldn't be TOO bad.

The contrast, viewing angle and colour issues of TFT/LCD/Plasma devices just make them totally unusable for many graphic, design, and medical applications, so CRT's are still used, but they're actually becoming rarer as the manufacturers jump on the LCD band waggon.

viewing from a distance isn't an issue in those fields, the quality is premium.

there was a slashdot post asking for help with medical imaging a while back because of this..

I've been very much looking forward to CNT/NED displays, and jsut wondered how SED really stacked up.
