Check these bad boys out.

Bezels? No Bezel here. See here? No Bezel.

Those arnt OLED :p Just LCD's with LED backlighting.

But damn I wish that Display with the small bezel was 1080p!

22 inch 1680*1050*57Hz PLEASE. I would pay $1000 for a shipped set of three,

These are two unrelated products and neither is an OLED.

Consumer level OLED displays above 11" are still unfortunately several years off. There are too many difficulties manufacturing them.

The LED backlit TVs are nice, but currently have much too high a price premium over comparably high end CCFL backlit sets.

Clearly I like pictures more than text.

If I could hang three of these on one large wall, I think I might give up the 5040x1050 res.

OLED has a serious problem other than price and manufacturing, the latter of which ironically is claimed to be a more affordable than LCD, a mere ink jetting process. The grid of material forming the diodes within the film has to be precisely calculated though.

The blue part of the color spectrum in OLED tech is very vulnerable to moisture contamination, even from slight humidity levels in the air. Thus the projected lifespan of OLED sets is only about 30,000 hrs best case scenario, half that of LCD.

That's IF you believe Sony's very questionable claim, which some manufacturers such as Sharp have refuted based on contrasting lab results showing more like 10-15,000 hrs at best for OLED lifespan.

The technology I'd rather see manufacturers pursue is PLED. It's basically the same concept only with a polymer based substance on the screen vs organic. The polymer helps resist moisture contamination. Even the very first PLEDs tested in a lab lasted 198,000 hrs.

There are other key differences that could affect price. PLED was discovered at Cambridge University in the UK, whereas OLED was invented by Kodak. PLED definitely has more humble beginnings and is potentially superior technology.

OLED technology is licensed by Kodak, so Sony pays them royalties. Cavendish Labs in the UK was formed by those whom discovered PLED tech. So far the only major manufacturer I've seen backing PLED is Philips, though it's been a while since I checked on PLED's progress.

Speaking of hanging on a wall, that is one of the key advantages of this technology. The substrate the film is sprayed on can be super thin, even curved. It's possible to make very low profile TVs that literally hang like paintings on the wall, not to mention with no back lighting needed or viewing angle problems and superior contrast and color.

mmmm SED/FED.

I'm less inclined to think SED/FED is going to be the next viable TV tech, simple because it's been on paper since the 80s and still no one has come out with a production model or even prototype as far as I know.

There have been working models of SED shown to the public.

OK, if that's so, that covers the prototype anyway. Then why is there still no production models? It's been in the works for decades. Sony already beat them to production with an OLED, not that it's better tech, but at least it's out there.

Sony dumped FED last week which makes me :cry:

SED was shown off pretty heavily at CES in 2006, but its been absent ever since even though they claim that its going great.

That tells me either the cost of production was too high, or they couldn't get enough interest from investors and/or partners. Part of the problem is the economy the way it is now makes the timing bad for releasing drastically new tech.

There was a HUGE patent lawsuit by a small company. I'm surprised you didn't hear about it. The patent issue was cleared up, but the tech was delayed long enough that it might be the nail in the coffin for SED. It wasn't an investment issue either, Canon dumped very literally billions of dollars into SED, only to have the patent issue prevent them from releasing consumer displays. Last I heard, they were going to try to market SED as a professional display.

If that's the case, the tech isn't even worth mentioning as far as hopefuls to hit the market soon, or at all at the consumer level. I stay abreast of relevant info, this isn't something that apparently even had a chance of going mainstream, so I don't exactly feel out of the loop by not knowing. The less useless info in my head the better.

I am hoping for a PLED to be made soon.
