"Some web sites are reporting that Panasonic is set to unveil a 20" 4K OLED tablet at the IFA 2013 event next week. Those sites are relying on auto-translated Japanese text. But in fact the company will not show such a tablet. In an English PR, Panasonic says they will show a 4K 20" tablet and a 4K OLED panel prototype - those are two different devices."

Thanks for this info. I should probably remove my post with the article given that it's totally wrong...

It doesn't say anywhere in there if the 77" (or the 110" monster) is curved or flat.

Ahhh 77 inches. That's much better. 4K, OLED, and 77 inches. Yes, yes, and yes please. Oh and decent pricing too please...yeah I'm asking for too much :P

LG executives in Korea told the Wall Street Journal that the price on LG’s new 55-inch Full HD 1080p curved OLED TV has also been hacked nearly 30 percent in the Korean market to 10,900,000 won ($9,788) from 15,000,000 won previously.

A U.S. dealer, who asked not to be named, said he was told LG will similarly cut the price here on its model 55EA9800 55-inch curved OLED TV to a $9,999 UPP, from the original $14,999 introductory price.

The Wall Street Journal reported that LG’s OLED price cut was made to make the set affordable to a wider pool of consumers.

LG also reduced prices on its 55-inch, flat-screen OLED TVs to 9,900,000 won each starting this week, from 11,000,000 won previously. That set has not been introduced in the United States.

Samdung will still eat EllGee's lunch (well, for the ~1000 folks worldwide who buy one or more of these).

The Korean-to-English translation should be, "No one was buying any."

I tested the Samsung OLED again today. I edited my original review with some new information here:

That's good - it was a serious problem on the HMZ-T1. Of course that was an OLED microdisplay rather than a television, but it's still good to have confirmation that it's not a problem.

Still not as good as CRT or older Plasmas that didn't employ excessive filtering.
Interesting - I thought that Samsung were using RGB OLEDs without color filters, as close to the surface of the glass as possible. Having the image change with viewing angle suggests that may not be the case. (Sony have viewing angle issues on theirs due to the Super Top Emission cell structure.

OLED with black at 0.005 (nits) / white at 200 or another OLED with black at 0.0005 / white at 20? Both have contrast ratio of 40000:1.

Does anyone else get the impression that it might be a good idea to buy a 2014 plasma to carry you until they get the bugs worked out and drop the price of OLED?

Yep.  Been said many times.

Thanks for the updated review, the time you put into all this is much appreciated and I really did enjoy reading it all nice work. wink.gif

PS: I'm still going over it my head, why on earth did both LG and Samsung decided to release this display curved? Of course I'm holding off judgment until I see the curved screen in person but I'm thinking there had to be something both company's saw in common that led them to come to the same conclusion. Of course it could be something as simple as "monkey see, monkey do" thinking that this change in form factor would sell more displays, who knows for sure? biggrin.gif

It may have something to do with the AR coating. The fact that the tint was not even across the entire surface but more intense in certain spots (maybe 3-4 horizontal bands down the screen) makes me believe so. To be perfectly clear, I only saw it in full-screen colored slides. With actual video content, it would not be an issue at any sane viewing angle and distance. I think one of the other review sites noted a similar extreme angle tint so it appears normal for this set.

I would definitely wait for second generation models based on my experience. If you buy it now, it would be similar to buying a Ferrari and being told you can't shift out of first gear. The set has great motion resolution potential that you can't tap into for all applications. That is a shame and I would be pissed if they released a new model without that limitation.

I think what we're looking at with these first-gen models is some recycling of existing processing components. The menus even have a "cell light" setting which is obviously carried over from their Plasmas. The motion enhancement processor also appears virtually identical to their LCD units. I think in time, we'll see chipsets developed that fully tap into 100% of the OLED potential - including reduced input lag.

I think if you owned it for a long time, your brain would eventually learn to tune-out and ignore the curve. I noticed it much less toward the end up of my 2 hour testing session and focused more on the picture quality. I'm almost 100% certain the curve is there just to get people to stop-and-look at the store. Without it, there is simply nothing to make most people realize this is not LED LCD besides the sticker price. Store conditions are not a good way to sell these TVs and I hope the slow sales won't hurt the advancement and development of future OLED tech.

I may go out to review the LG next week. I'm kind of tired after spending close to 4 hours total on the Samsung but I'm curious how LG handles their game mode.

Have these companies indicated that they would continue to develop OLED displays, regardless of the sales of these first models?

Has Panasonic talked road map at all?

Registration is open for the "OLEDs World Summit 2013".  Sept. 17-19, San Franscisco.

 

You can also register for their free "webinar".

 

Whatever.

I'll take high contrast at a lower brightness any day... but 20 is too low. 50 is the lowest I would use, but you really should have double what you want, to account for brightness loss over time and to try and eliminate the ABL by keeping contrast low.

That reminds me... I looked carefully for any sign of ABL on the Samsung OLED. It simply does not manifest itself in regular content (at least in movie mode). I spent a good 5 minutes watching hockey. I then watched the same hockey clip on a Samsung 8500 Plasma and the ABL was very clear (I know this was improved in later firmware). I also watched a few commercials that transition into white backgrounds.

Regarding my earlier comment about viewing angles... maybe it wasn't the screen coating after all. I looked at a few screenshots of a Sony OLED monitor and their tint off-angle looked very similar. This testing of mobile Samsung OLED's also reveals their viewing angle is not as good as IPS LCD.

You can also see the same bluish / greenish tint I noticed in the pictures here:

http://www.flatpanelshd.com/news.php?subaction=showfull&id=1316433816

Maybe the enlarged blue pixels?
post #6890 of 9438
Also, I can confirm the IR sensor is in the bottom center of the Samsung OLED and not on the media box. You could in theory hide the box anywhere you wish.

I wonder if all the video processing is inside that little box or if any of it is inside the panel. Maybe Samsung could offer an upgrade to improve motion processing and/or lag with a newer box like they are promising for their 4K TVs.

A 4K 75" VT series Panasonic plasma maybe? Yup, I'm there in a heart beat!

I doubt a 75" 4K plasma as Panasonic has said no more R&D or substantial plant upgrade for plasma line, but the do have lines that were making the quickly disappearing 42" plasma, that could be converted to 84" 4K plasma.

No sense dreaming - it ain't going to happen! NO 4K Plasmas in the pipe!

Yeah, that does seem viable. It also would be something of an egregious power consumer and 80+" TVs are very niche to begin with. So in spite of the fact that it's plausible as a concept, it seems implausible as a reality.

Looks like they're sticking with that ugly dewdrop in the middle bottom of the bezel like Samsung seems to be.  I hope that thing goes away soon.

So this is the first Flat OLED screen from LG.

Will be available in Germany late in September and keep rolling out in the rest of the world after that.

A model with the same name - 55EA8800 - was present at the CES so it is not ''the newest model''

^^^ Yet another marketing department running out of ways of changing the stand????  I'm tempted to ask "what next", but after some of the stuff I've seen from LG and Samsung lately.....I'll hold off from fear alone.

 

EDIT: I was hoping to change my mind.  But nope: That stand is freakshow hideous.

Curved models, and now wide picture frame models. Why are the makers intent on gilding the lily, and drawing attention away from the quality of the video display in their First Generation large OLED TVs? It is almost like they do not want to have shoppers paying close attention to the actual image processing.

 

Greenland, stay tuned for the rabbit ears coming your way soon....
