Toshiba and Canon claim SED TVs will be here in two years, but will the price be competitive?

Reuters reports that the joint surface-conduction electron-emitter display venture between Canon and Toshiba will have to wait an extra year or so.  At the Consumer Electronics Show in Las Vegas two months ago, the two companies announced that SED displays are just inside a year for commercial use

With the cost of LCD and Plasma TVs in near freefall, for SED TVs to gain any market acceptance, the technology needs a dramaticly cheaper cost or dramatically apparent feature.  Right now, DLP and similar technologies dominate the high fidelity market while LCD and Plasma TVs have dropped so much in cost that SED has a difficult task ahead of itself to really unseat either technology. 

For example, low end 37" LCD TVs used to cost approximately $2,000 about this time of the year in 2004.  Today, you can walk into any Costco or Frys and pick up a 37" Syntax LCD for $1,300.  The price drop is even more dramatic for larger sized LCDs.  DLP prices have experienced similar drops, but have also increased resolution dramatically in the last two years.  For SED to really have a fighting chance out of the gate, Toshiba-Canon would need a 37" to 40" SED TV for under $1,500 to compete with sub-$1,000 LCD TVs of the same size. 

Toshiba and Canon have promised nearly $2B USD to keeping SED technology afloat, though Intel made similar promises in 2002 with LCoS technology.

SED = return to the past

SED technology is like a trip to the past since it works exactly like a CRT monitor.
That means the monitor flickers and you get headaches and eye fatigue.

Another STUPID technology is the one wich will be implemented in the next AU Optronics BenQ LCDs, the technology is called BIF (Black Interleav Frame) wich displays a Black frame on you're monitor after every 6 displayed frames, that means from 60 frames per second 10 are blacks and only 50 are displaying the real image.
They call this technology a eye washing technology but this is the most stupid technology I've ever heard off.
This will produce even more monitor flickers, headaches and eye fatigues.

SED and BIF technologys must take the RAZZIE AWARDS for the most stupid technologies ever to come.

I've got to disagree with the no content argument. I've had HD (a JVC LCoS, TW cable HD feed)for a little over a year now. The majors all carry HD for sports and prime time programming. Discover also carries quite abit of HD programming. While I'd still like to see some more complete coverage, I think that the lack of content argument is no longer a strong reason not to go HD if your in the market for a new TV.

I haven't seen one but I wouldn't think it would flicker. CRT scans the screen surface with a single electron beam, The scanning pattern causes the flickering. SED has individual electron emiters for each pixel.

Oh yeah ??

Just read the following article and watch the pictures that shows the flickering.

The reviewer below didnt seem to have any such issus

"One of the video sequences shows a streetcar moving from right to left. This second test really is impressive: with the LCD the result is disastrous with huge ghosting effect and with the plasma, sharpness is reduced. Video displayed by the SED it is magnificent. I have never seen something like that, even with a CRT. The object lines move without any blurred effect."

What review that was a presentation of the technology not a review.
What's funny it's that even on that article if u look close to the pictures u will see a black stripe on every SED monitor, and that's the flickering exactly like on a CRT.

Its up to u if u will buy such a monitor but more than sure I'm not buying it.

But I guess there are plenty of stupid people out there that will buy them.

could that bar not be the screen refresh out of phase with the shutter speed?

Either way no-ones going to buy anything with a bar down it are they? Sounds like you think we are going to go and buy one blind tomorrow....or your just trolling and dont really care?

Myself I think SED looks very interesting and am sorry to hear its been put back- the problem with that is theres more chance now that another technology will be bought to market to solve this contrast ratio problem, perhaps even one that can change resolution (SED, while being based on crt tech, will still have a fixed native resolution).

Also Ive yet to be convinced that the power drain of a panel comprised of tiny electron guns will be less than a plasma, but we'll see in time.

I think OLED has a very strong possibility of disrupting SED and FED in future techs. Its cheaper, more mature and solves all of the problems of all displays right now (is flexible, faster response time, less power) except variable resolution. However, the variable resolution is becoming less and less of an issue because the resolution and DPI is increasing so fast.

That's assuming the OLED lifetime problem can ever be solved. OLEDs degrade fast, and no one wants to replace their big-screen TV every six months.

> "I haven't seen one but I wouldn't think it would flicker."

Any matrix-addressable array of elements is going to flicker without latching. Remember the old "passive-matrix" LCDs? They flickered just like CRTs...but because LCDs are absortive technology instead of emissive, the result was washed-out colors, not eyestrain. That problem was solved by adding a transitor at each pixel to latch state information.

The first SEDs are nonlatching; therefore they'll flicker. However, because they allow an entire row to be addressed (and thus displayed) at once, they should flicker far less than an old-style CRT, which could only update one pixel at a time.

No, I think LCD takes that award. Compared to CRT's they have worse colors (especially dark ones), limited viewing angle, locked in resolution, and slow response time. I don't see how such an inferior technology ever became so popular.

Why do we need all these new technologies when none of them are really superior to the old one.
