Canon-Toshiba Joint Venture On SED Collapses 93

Posted by kdawson from the future-so-bright dept.
An anonymous reader writes "SED (Surface-conduction Electron-emitter Display) displays were supposed to be the brightest, most energy-efficient TVs to hit the market, so Canon and Toshiba created a joint venture in 2004 to capitalize on the emerging technology. The resulting entity, SED Inc., was sued in 2005 by Nano-Proprietary, the company that licensed SED technology to Canon in 1999. Nano-Proprietary says that the deal it signed with Canon doesn't extend to Toshiba. Rather than continue to fight the lawsuit and delay SED even further, Canon has now decided to buy out Toshiba's stake in SED Inc." Canon says that SED TVs will be delivered on time in Q4 of this year, but volume manufacturing (which Toshiba was supposed to handle) is being rethought.

          My understanding is that the part of the CRT that's hard (and, therefore, expensive) to manufacture is the shadow mask, and SED's don't have a shadow mask, so a lower manufacturing cost is still something that could be hoped for. We'll have to see what happens. I've been watching the SED technology for a decade, and it's been a couple of years off that whole time.

    This display seems like a very interesting step forward. Huge Contrast ratios (in the tens of thousands), fast response time, and a very nice viewing angle. I just wonder how long after they hit the consumer market that they will be in the common living room. Besides the hardcore enthusiasts, people will not be anxious to give up their brand new LCD flat panel TV and replace it with one of these. Oh, and one thing they should test for in QA is how hard of a throw it can withstand by someone who lets go of their Wii Remote.
    • Last displayed models had contrast in the millions, not tens of thousands... The reason, black is pretty much true black, i.e. no light emitted, only extremely limited bleed from pixels directly next to them due to the way the technology creates the light in the first place. LCD's have a backlight that can never really be gotten rid of until a per pixel backlight is created (or a per pixel block, i.e. every block of 4 or 16 pixels have their own controllable backlight).

      • I think the limiting factor will be that they want to use the power savings of the set as a selling point, and having a refresh rate 2x the speed of the competition would mean you need to use almost 2x the power since that would mean sending 2x as many electrons through the nanotube guns of the emitters.

        Why would the power increase that much? Maybe I'm not understanding part of the technology, but I would think that the electron stream would remain constant if there was no change in the color through a pe

      I was hoping that SED would be the driving force in bringing down the costs of LCD and Plasma and competing competitively with them especially after all the hype.

      There is a new/old (started early 1970's) technology called FED (Field Emission Display) which is being developed by Sony and they already are demoing 26in and 30in versions at 1080p, although they do need to demo much larger ones to be taken seriously.

      However FED like SED may not be acceptable if the overall costs are not significantly cheaper than LCD and Plasma. Still this technology may force further cuts in the flat panel market, which IMHO can only be good for the consumer. If you don't have a HDTV yet and are contemplating buying one, a six months wait may save you a considerable amount of money.

I find a 23" display is big enough, but the difference between a 100dpi and a 200dpi display is staggering in terms of visual quality (particularly when reading text; you can say goodbye to hacks like sub-pixel AA). Unfortunately, the cost of a 200dpi TFT is about two orders of magnitude (base 10) more than the cost of a 100dpi one. Anyone who can sell a reasonably cheap 200dpi (or more) flat screen

However, both technologies of LCD an LED are owned by Taiwanese companies. Some of them are even ready to produce LCD panels with LED backlight units. Although the price of LED backlight unit is currently much more expensive that of traditional CCFL, it may be lowered to a relatively low level in the next few year. As a result, LCD will knock out all rivals in the world and dominate the market of flat display panel.

    What's interesting to me is the bottom part of TFA titled "Legal Mumbo Jumbo". I haven't been following this, but it sure sounds like the case has been awfully contentious.

    Most important though, the complaint is (1) that Toshiba wasn't licensed and (2) that there is a breech of the agreement with Canon over "excluded products" (among a bunch of other stuff). That might mean that - Toshiba or not - Canon's not going to be free of the lawsuit, and not going to be releasing SED products either. Curiously, Nano's site doesn't mention any other licensees of their technology. So...one has to wonder if Toshiba and Canon together can't get these things to market and make them competitive, then who are they hoping to find that can do it?

    Seems to me the best move would've been to let Canon/Toshiba take them to market and then go after all the competitors (Sony, Phillips, Hitachi, etc) for a license when they try to enter the market. But I guess that's why I don't own a multi-billion dollar electronics company.

    Add an SED to a laptop with solid-state storage (which, by the time this is feasible, will be at least where laptop hard drives are today), and the continuing work on processors that can shut themselves down nicely, and we may get some truly efficient laptops out of the deal, that only use power when actually doing something.

It looks like an attempt to renegotiate (extort) for more money now that Canon is getting close to a real product. SED may wither on the vine if this keeps up. With years of development, I would be certain Canon has it's own IP portfolio that would pretty much eliminate anyone else going forward.
