post #7111 of 9446
Are there any OLED owners yet?

I wouldn't worry about where the thread is started as moderators can move threads around and create new display devices within the forum structure.
post #7112 of 9446
Any OLED owner thread will be moved to this Forum till a OLED Forum is created, Flat Panels General and OLED Technology has been added for this purpose.
post #7113 of 9446
Well, there's now an owner of the Samsung OLED on the UK-oriented AVForums, and he seems to be very happy with his brand new purchase.

In point of fact, it's actually his second OLED set. :-)

He also owns one of the small Sony portables, so at least it shows one customer so satisfied with this albeit currently pricey technology that he's gone back for more.

I ordered the Samsung S9 today, with a strict fulfillment date of October 14. I want it mostly for Bluray movies, and I expect it will look great in my dim room. I've already downloaded the manual to get things started.

I hope the Oled will resolve the issue of banding. Notice the layers of gray around the white letters...

I would rather have a 4K section for the thousands that will need it, than an OLED section for the tens that might.

Found this old news to be sure 7/18/2012
LG charged with stealing Samsung OLED Tech

http://www.techspot.com/news/49436-lg-display-workers-charged-with-stealing-samsung-oled-secrets.html
then this
Samsung office raided over LG OLED tech theft allegations 4/10/2013
http://www.neowin.net/news/samsung-office-raided-over-lg-oled-tech-theft-allegations

I'm Sure this horse has been beaten here before what's the real story or we don't know yet ?

Did LG steal from Samsung or did Samsung steal from LG or did they both steal from each other!
or maybe nobody stole anything
I they have similar but different panels

not much beyond 4/13 with So. Korean police raid at Samsung?
I bet if anyone asked Apple they would side with LG biggrin.gif
Seem like the Japanese companies usually share technologies or at least stay out of patent wars for the most part
any new news ?

Now Sony's in the mix I believe making their own panels? or maybe using LG panels? and then there is the
arrangement with Sony and Panasonic.,What about Sharp IGZO OLED , No Toshiba OLED??? or will they re badge ?

I don't agree that a separate 4K forum is needed, as all display devices will eventually be 4K and will simply continue to be discussed in their respective forums.

But OLED is a whole new technology and requires its own forum, even if (at the moment) it will serve far less forum members or visitors.

This is often a source problem rather than a display problem. If you're not watching Blu-ray, it will be a problem no matter what.
But hopefully OLED will bring us back to CRT levels of gradation. 10-bit LCDs and LCoS displays are close, but not quite there.

I agree with you.

We will see -- the store demo video showed no sign of banding in scenes with bright bulbs and dark backgrounds. There's also a panning shot of a lighthouse with glorious sunlight shining through and no hint of banding.

I found the same thing in my review. The Samsung OLED is very good at revealing flaws in the content. All sorts of compression artifacts, noise, and banding show up on this set when watching less than ideal sources - especially broadcast TV. Luckily it's minimized in the movie mode. I looked at several color-scale ramp patterns and did not notice any unusual banding. Probably just a calibration issue or badly encoded source.
post #7127 of 9446
^^^Is banding and contouring the same thing?

Also, is noise mainly an issue with plasma sets?

What you called "banding" above is indeed contouring or, more properly false contouring.
post #7129 of 9446
Has anything been said about the OLED displays having or not having ABL???

and for that matter, just how linear gamma and color is at various brightness levels?

The now-legendary traditionalism of avs masters flatly rejects skipping the word "flat" from established forum names as that would amount to a revolution with unpredicatable consequences in bending and twisting which could have grave impact on straight revenue flow biggrin.gif.

There is no need for separate 4K section. 4K displays enter now the mainstream and fit into the existing display fora.

Yes.  Actually, it's usage probably came from the neuro-optic usage of "contouring", which I've only seen as the sub-concept illusory contouring where the brain sees lines that aren't there.  Graphics apps that I've seen use the contouring term (when forced around objects).  The graphics/imaging based companies even back to the 80's mostly used "banding", when used as a description of an unwanted artifact of low color/shade depth, but did occasionally use them interchangeably.

It may not be the source. Early HDTVs were blamed for being very good at exposing the flaws in highly compressed sources due to their resolution, clarity, upscaling, or whatever other reason people thought it might be. What was actually the problem, was that HDTVs - especially the earlier ones - were not very good at gradation. So what was a subtle shade difference between two macroblocks on a CRT was magnified due to the lack of gradation on the HDTV.
This is one of Plasma/DLP's biggest weaknesses in my opinion - they are not very good at gradation. With a good source, you don't have as many compression artefacts visible, so the problem is not as obvious, and it's easy to blame the source rather than the display.

Simply looking at a grayscale ramp is not necessarily a good test. Certainly it will highlight gradation problems on a particularly bad set, but many displays can pass this test and still have problems with actual source content - particularly in dimly lit scenes.

They have an ABL. I have not seen measurements from the LG or Samsung displays, though Sony's OLEDs behave like CRTs where reducing the contrast also reduces the strength of the ABL, so once you are down at 70% contrast, it is effectively eliminated. Hopefully even if we have to live with an ABL, all OLED sets will behave like this, and not like Plasmas where the ABL is fixed regardless of contrast.

I look forward to it, and it's good to know it won't be hidden away in this thread. Should be here in two or three weeks.
Let the count down begin!

Is that an OLED set? Congratulations - looking forward to hearing all about it when it arrives.

That's usually caused by a palette reduction algorithm in the source material. One of many ways compression is done.

Samsung and LG are done suing each other:

"Samsung Display said in a statement it has "come to an agreement with LG Display to focus on finding ways to cooperate on patent matters though discussions, and to immediately drop lawsuits over liquid-crystal displays and next-generation organic light-emitting-diode display patents."

Objectively, this is good news.
