Not sure if this has been posted but looks intresting!

I'd only seen still pictures of this before, but I have to say that looks very very impressive.

[LewisD]

Whoa, that looks incredible! :D

It'll be good to see some of the 50" screens of the future thats for sure.

[Caimbeul]

That is seriously cool! - could just clip or stick the screen to the wall.

This is the end of LCD and definelty for plasma-was considering upgrading my Bravia, but I'l wait till these bad boy's are out in the shops. Once R'nD is paid for these will be cheap too.

I also beleive this is the way forward for 2D displays. LCDs still have their issues and plasmas also have a few bad points.

Its a shame SED doesnt seem to be working out for Canon and Toshiba.
I thought SED would be mainstream for larger screen sizes and OLED would be mainstream for smaller 20" to 30" sizes.

I still hope these new formats take over LCD and Plasma.

Looks fantastic. However, I can't help but think - there were lots of still life images weren't there. Not too much fast action stuff. I wonder what the response time of these new panels is? Quite slow, I would imagine. Ghosting and lag galore, I suspect.

I would expect response times to be almost infinitessimal; certainly at least as good as CRT.

Based on what evidence or logic?

I don't agree by the way.

All the reviews I've seen of OLED suggest that their response times are pretty good.

One of the major reasons that Sony are introducing them for camera viewfinders is the deluge of complaints they received from camera operators covering sports when they switched to LCD viewfinders on HD cameras, from CRTs. The laggy LCDs didn't allow for decent coverage of fast moving scenes, and were a nightmare on golf and tennis.

AIUI when Wimbledon started using HD Cameras last year, they had to ditch the LCD viewfinders and introduce a slightly "modified" CRT viewfinder from an older HD series camera?

[Stephen Neal]

Interesting that Quantel have announced they are adopting, or plan to adopt, OLED displays for some of their HD post-production devices.

I guess they were forced to switch from HD CRTs to LCDs - and haven't been happy with the colourimetry, especially for grading applications?

Conventional LEDs or laser diodes can be pulsed fuly on or off at a frequency measured in Gigahertz.

Very interesting. Nothing to do with OLED though, is it. The "O" is significant I think.

In the intro bit of this section of the forum, the top post says:

Compared to current flat panels:

* Cheaper to make
* Very thin - 30% of thickness
* 1,000 times faster response times
* CRT like black levels
* Requires 25-30% less power
* Potential to be flexible – hence able to roll like a drop-down screen.


Any word on when to expect these at a consumer level in the UK?

[Chippy99]

Fair enough!

Strange Sony didn't show much in the way of moving images then.

OLEDs (refering to the actual organic light emitting diodes, not OLED TVs) work in exactly the same way as normal LEDs, but are just made out of a different material.

The "o" stands for "organic", and refers to the light-emitting layer of the device being an organic (i.e. carbon based) compound, rather than an inorganic compound.

The reason why the material is significant, is because the polymers that you make OLEDs from can (theoretically) be made very easily and cheaply into displays using a technique similar to ink-jet printing.

In other words, once the technology is sorted, making the display portion of a TV would be a matter of carrying out some printing and deposition steps. This should lead to very cheap displays compared to LCDs or plamas (which while both mature technologies will allways be complicated to make for their own reasons).

[Chippy99]

Thanks for that, although I think we all knew what the "O" stood for.

I have since conceded that the response times don't seem to be an issue.

However, to look at the response times for normal led's and extrapolate that to just presume that the performance of oleds will be the same is a wholly unreasonable extrapolation.

The very fact that oleds are made from organic material means their performace could be completely different from that of ordinary led's. Hence my original concerns.

Anyway, it seems the response times are in fact fast, so its a non-issue.

[Stephen Neal]

AIUI the major issue with OLEDs isn't the response times, it is the organic material decaying. There are suggestions that in some environments (particularly hot and humid conditions) that the organic layer can go mouldy... AIUI they are working at better methods to seal the layers and prevent contamination from the outside world?

lol why "definitely" plasma and not LCD?

new video of sony OEL tv hope they get bigger tvs fast.

How can it go moudly?
Just because it's called "organic" it doesn't mean that it's organic the same way as living cells are. Organic merely means that it's based on carbon, like graphite or diamonds or a whole lot of materials that are based on carbon.
An "organic" molecule doesn't go mouldy, only living organisms "go off" like that, caused by bacteria.
The problem with the decaying of OLEDS is the same as with lots of other materials, in that the material fades after a certain period of time. I don't see why bacteria would make this material mouldy any more than it does for LCD or plasma screens, or our walls when it's damp and hot...
Besides, if the TV is in such humid environment to start being mouldy inside, then it would probably stop working way before mould appears as it would just be too wet for the electrics to work properly.

All the above is of course useless if i seriously missed something.

[Chippy99]

Dan,

Your sig line made me laugh.

Reminded me of something Rodney Marsh the footballer once said. He was being given a talking to by the manager at his new club. The manager said he would pull him off at half time. Rodney replied "Wow, that's very good of you. At Man City we just got an orange." LOL

This PR that I received today looks relevant (to OLED) :

[mrtbag]

One of the first Sony products to have an OLED display built in is the PEG-VZ90 handheld.

The response time tested at 25 degrees was 0.01 mil sec.

[joshua_bond]

As a side-issue...Mould is primarily caused by a fungus (not bacteria).

I agree with everything you say - there is no intrinsic reason why something made of organic molecules (i.e. those composed primarily of carbon and hydrogen atoms) should go mouldy.

I was simply reporting that the experience of early OLED displays was that they had a limited life, and did indeed go mouldy. This may be because they were being evaluated in camera viewfinders - and in outside broadcast situations condensation can be a real issue, as equipment is moved between locations of varying temperature and humidity. (Anyone who has moved a camera from a cool exterior location into a hot and humid interior and seen lots of things fog up will have experienced this).

The flexibility of cheap, bright, thin film displays has limitless potential.
Moulded panels in and on vehicles and planes, wall coverings, furnishings etc.
You could change the appearance of your home inside and out to represent anything you wished. Vehicles and furnishings could change colour (or display a new woodgrain) at a voice command.
Clothing could be programmable and even make you invisible if it showed the background. Lots of potential there for warfare. (If they haven't gone over to fighting with robots or even fight their real battles in enforceable computer wargames by then)
You could make your house disappear into the background or make it look like it is made of priceless materials in an instant. They say 3D screen technology is just down the road.
You ain't seen nothing yet!
