- kent1146, on 10/12/2007, -3/+17It's going to end up being all about price. Far too many people buy a $3000 TV, just to bring it home and stick a yellow composite video cable in from their DVD player, or hook a coax cable from their cablebox into their TV.
Very few people out there today know the difference between LCD and Plasma technologies. Even fewer people care. All they care about is the most price-efficient technology for the screen size they are looking for. If SED is to gain adoption, it must have a price advantage over LCD and plasma. - geminitojanus, on 10/12/2007, -5/+19For the non-simpletons: SEDs are basically multiple gun CRTs. Instead of the electron beams being deflected by a magnet whose field is varied by control circuitry, the electron beams are shot directly forward into the image element (a tiny dot of phosphor). In front of each image element is a different material that changes the color of the light emitted from the phosphor, and we get the image displayed, bright and as crisp as a CRT, but with pixel densities rivaling that of LCDs (and quite frankly, surpassing it by a huge margin in the upcoming years by the reduction in size and cost of semiconductors like those necessary to make the electron emitters).
(The reason a printer manufacturer came up with this idea is because it's very basically the same idea we use with Inkjets). - masamunecyrus, on 10/12/2007, -0/+12You forgot the fact that the first SEDs will launch in second-third-quarter 2007 with a 10000:1 contrast ratio by Toshiba, and while they are expected to be "Ferrari-priced," they are eventually supposed to become cheaper than Plasmas or LCDs.
AND there's only a 1ms response time! The ultimate gaming TV!
I recommend Wikipedia's article.
http://en.wikipedia.org/wiki/SED-tv - TheG2, on 10/12/2007, -0/+11Wow, watching a compressed flash movie is such a great way of seeing just how clear the technology is!
- inactive, on 10/12/2007, -8/+14I clicked this link assuming it'd be some new update on SED technology - like, you know, something that hasn't been written and blogged about for a year and a half now. Stupid me.
- DaffyDuck, on 10/12/2007, -0/+5"SED-TVs do not utilise a scanning beam the way CRTs do, therefore they do not affect your eyes the same way."
Exactly. SED's do not have a "refresh rate" like CRT's. They are more like LCD's in that each pixel is controlled independently. The difference is that response times will be much better than both CRT's and LCD's. LCD's have to wait for the crystals to physically move to change state. CRT's have to be refreshed every 1/60 - 1/120 second. A pixel on a SED can be turned on and off almost instantaneously. - siodine, on 10/12/2007, -3/+8Yeah, laser projection is a much better technology than SED, allowing you to view 97% of the colors your eye can see while costing 1/4 of what TVs cost today.
- Zreitan, on 10/12/2007, -0/+4the dude ddoing the interviews is a douche...it sounds like hes being paid to blab on and on about how great it is...
- Jimmyinnz, on 10/12/2007, -0/+4Sorry danielh4824, I totally disagree with you. On my desk in front of me there's a 23 inch Philips CRT and a 21 inch Philips LCD on a dual head card. There's just no comparison between the two.
The difference is akin to vinyl versus CDs playing classical music. The vinyl has a warmth and clarity that CDs cannot emulate, even after all this time.
The CRT is completely adjustable as to warmth (color temperature), brightness, contrast and a host of other adjustments. The LCD is limited and can never show 1 pixel width text without bleeding.
The only comparison that I can really make is the weight. 30 kilos versus 2. - nogami, on 10/12/2007, -0/+4Huh? "Bad for your eyes and a whole list of other stuff"?
You do know that the only thing that SEDs have in common with CRTs is that they both use electrons to excite phospors to create light...
LCDs are AWFUL for viewing angle. Move more than 30-40% off centre axis (or less) and the colours and brightness starts shifting. Oh yes, and LCDs also have a poorer refresh rate, horrible contrast ratios, and a backlight that will eventually burn-out (not to mention that it doesn't provide equal backlight linearity across the entire screen.) - combatchuck, on 10/12/2007, -0/+4My LCD has a 170 degree viewing angle. Viewing angle was a problem 5 years ago, not today.
- chongli, on 10/12/2007, -0/+4SED-TVs do not utilise a scanning beam the way CRTs do, therefore they do not affect your eyes the same way.
- DaffyDuck, on 10/12/2007, -1/+4"and probably has all the bad aspects of CRTs, such as the "refresh rate""
No. Do you understand how CRT's work? A beam of electrons is controlled by an electromagnet which scans the beam across the screen and down a line then across again...like a typewriter. The refresh rate is the time required to "print" across the entire screen. With SED, each pixel is an electron emitter. There is no refresh rate. In fact, it's faster than LCD which requires physical movement of crystal molecules. - Ireland, on 10/12/2007, -0/+3I've been waiting for something like this for some time now. I'm the kind of guy who can't stop looking at the not-so-black letterbox at the top and bottom of my beautiful new 1 year old Sony Bravia when a movie is playing. Frankly I think in some respects LCD and Plasma is a step back from the old CRT's, and this post and technology has proven I'm not actually paranoid. Other people must notice this thing too, it's not just me, and the viewing angle thing is a joke that is now finally being ratified. A TV needs this level of contrast, if you want those letterboxes to look pure black like the old CRT's. Thank God for that! And thank Canon and Toshiba for SED!!

That's all marketing hype. The article on the technology was posted by the company that developed the technology. No major manufacturers actually plan to bring the technology out any time soon.

As for SED, it's getting a little late now. It is definitely a superior technology. However, by the time it hits the market in late 2007, LCDs and plasmas will be far cheaper and look only slightly worse. The average Joe won't pay $1000 more for a slight increase in picture quality. - BenHanby, on 10/12/2007, -0/+3Exactly. He lost all credibility for me when he said the distance between the two glass plates is 2mm, which is "about half an inch". Hello? Have you been to grade school?
- magus_melchior, on 10/12/2007, -0/+3@kent1146
Kind of like this article, putting up youtube videos of the TVs in action... - super_duper, on 10/12/2007, -0/+3I don't know why they would pick such an inarticulate guy to do an interview.
- iAlex, on 10/12/2007, -0/+2I already knew this. SED is amazing. I am waiting for SED and probably won´t buy a plasma or LCD TV.
- sn00kie, on 10/12/2007, -0/+2The asian guy in the video really needs to find a new job....I thought he was nervous at first but then he decided to describe how the tv made him feel...speechless, which was evidently pretty hard to describe
- jvolkman, on 10/12/2007, -1/+3Unfortunately, dead/stuck pixels will be a possibility just like with every other modern thin-screen technology.
- mxcl, on 10/12/2007, -0/+2I recently got a 720p LCD screen, I'm not that happy because:
* Poor blacks, mean poor contrast in dark scenes, or even if some guy wears a black t-shirt.
* Upscaling of standard definition signals sucks a lot, it looks blocky and pixelated.
CRT wins completely overall. SED can fix the first point, but not the second. Getting a Wii? Stick to HD-CRT, you don't get upscaling on HD-CRTs because the tech is awesome. Just large. - mitrovarr, on 10/12/2007, -0/+2One really nice thing about CRTs is that they are capable of displaying dozens of resolutions between their max and min settings. LCDs generally only perform well at their standard resolution, and possibly at 1/2 and 1/4 of it.
This is really helpful while gaming, because you get to have high resolutions when your hardware can handle it, while not being forced to it when it can't.
It sounds like SEDs don't do this, being forced to a single high resolution like a LCD, which is unfortunate. - Ireland, on 10/12/2007, -0/+1I said ratified, but I meant to say rectified. You get the point though.
- ah802, on 10/12/2007, -0/+1According to Digital Times; All Samsung LCD monitors are to be LED backlite by 2008, and technology like Bright Side is leading the way. SED seems like a plasma plug to save the production equipment. Toshiba is running the dark horse again.

Actually, the Canon Rep said 2mm was 1/2" which boggles the mind. Can you imagine a vacuum between 1/2" of space on a 50" TV? The glass would need to be seriously thick. - gadgetsguy, on 10/12/2007, -0/+1Plasma bleeds ... LCD does not.
- KungFutse, on 10/12/2007, -0/+0Isn't one of the main drawbacks of OLED is the lifespan. From what I've read, it has a shorter lifespan of even LCD or Plasmas.
- garreh, on 10/12/2007, -2/+2"SED-TV is also so precise, that an object moving at high speed can still offer crisp clear letters! On any other TV, a blur would utter this impossible, but not with the SED-TV display."
So does that mean no more ghosting? What's the refresh rates like? - crossers, on 07/17/2008, -0/+0all this is great! And SED is amazing!

http://www.chasr.org/ - millixaw, on 10/12/2007, -1/+1Are these fixed-pixel display like Plasma and LCD? If so then CRT will still be king.
- whothehellareyu, on 10/12/2007, -1/+1Actually, the contrast ratios ont he first SEDs will be somewhere in the 50,000:1 ratio. That's the point, the black levels will be incredibly deep, supposedly. We'll see, I'm watching with interest.
- pauldonnelly, on 10/12/2007, -1/+1Are you maybe thinking of CRTs bleeding? LCD screens don't do that.
- Lagged2Death, on 10/12/2007, -1/+1@Jimmyinnz: "The LCD is limited and can never show 1 pixel width text without bleeding."
Bleeding? LCDs aren't supposed to do that. It can happen if you're using a VGA (analog) connection for the LCD, though, in which case you're not experiencing LCD at its best. - danielh4824, on 10/12/2007, -1/+0Better LCDs are on there way with better contrast ratios. They use LED backlighting technology I think if I'm remembering right. There are some LCDs that actually have pretty good viewing angles, and other companies are improving.
- billege, on 10/12/2007, -1/+0This tech seems to be just like OLED, in that it's always "just 1 or 2 years away" from making our TVs so much cooler.
The problem is that LCD and plasma keep getting better and cheaper, and there are no SED or OLED or laser TVs available for purchase. Yet, for some inane reason the articles keep popping up when some idiot who didn't hear about these 3 years ago finds out and thinks it's new.
When there's an OLED or SED on the market, the US market, please feel free to start digging articles about them again. Until then, find some other old/new tech that's not out yet, but keeps being promised. Maybe the n00bs can find some articles about fusion power and what a revolution that'll be and digg those... - eclectro, on 10/12/2007, -2/+1I agreel. If you buy one of their products, you might blow your hand off. Canon though, has always had quality products.
- foxhoundadmin, on 10/12/2007, -13/+12i thought lasers were the next generation of displays. :P
- inactive, on 10/12/2007, -2/+1I've been waiting for this damn TV to come out for years. I can't keep waiting damn it, I need an HDTV already but I hate LCD and plasma. Damn you Toshiba HURRY UP
- grabbadate, on 10/12/2007, -3/+1This is all well and great, but how does it compare to OLED technology?
OLEDs have been the promised "killer screen", with their super-high contrast, fast response, and phenomenal colours... Seems to me like SED is a backwards tech... It's probably not nearly as power efficient at OLED, and probably has all the bad aspects of CRTs, such as the "refresh rate", etc...
No, I think OLEDs are the future, not SED. - masamunecyrus, on 10/12/2007, -5/+3I'm also confused as to why he was dugg down (in the first post, the second one was obvious); because the next TV wars will be Laser vs. SED. The first SEDs will have a 10000:1 contrast ratio. From current information, both SED and Laser TVs will use less than 50% of the power of a similar-sized LCD, and they will have 50,000 hour lives.
Personally, though, I think that it will be SEDs in the large and living room TV market and Lasers in the small market and projection market. This is because the SED TVs will only ship in large sizes (as said by Toshiba), and they will eventually become cheaper than LCDs or plasmas, and while Laser TVs will also come in large sizes, they will be able to be scaled down for use with things as small as PDAs and cellphones. Laser TVs will be cheaper, as well.
Of course, we'll never know until both technologies are in a store and we can compare the picture head-to-head. Both have amazing potential. It's about time the manufacturers do HDTVs right. - ROFLance, on 10/12/2007, -5/+0"and studded with 160 diamonds (4 gm) of diamonds."
diamonds of diamonds? wtfx that mean? - Agares, on 10/12/2007, -6/+0Oops wrong topic.
- siodine, on 10/12/2007, -10/+3...
- danielh4824, on 10/12/2007, -7/+0I hate it! I hate CRT TVs in general since there bad for your eyes and a whole list of other stuff. I'm a big fan of the LCD screens because of the size and all the benefits of CRT and Plasma displays. This hybrid technology I feel should have been a transition technology in between CRT and the switch to LCDs. I feel this TVs will be bought by the same people who feel Plamsa is the be all end all, the people who have money to blow, and people who are the hardcore gamers. I'm sticking LCD technology that I love.
- NanoStuff, on 10/12/2007, -11/+1SED looks like the win if I can get ~21" with DVI. I'm not holding my breath.
