Official OLED Q&A Thread

[Robert Zohn]

I wanted to answer some unanswered questions and issues pertaining to OLED TVs. From reading several other forums I've found some unanswered and incomplete information, which I will put here so we can discuss this topic with clarity and accuracy.

Most of the questions are related to LG's current and new 4K Ultra HD OLED TVs. One unanswered or incorrectly answered questions is in regard to the undefeatable noise reduction circuitry (assuming LG does not correct this with a firmware fix) how it will look on the upcoming 65EC9700 4K OLED display. Here's the actual answer:

I first asked David Mackenzie who explained that assuming the same code is used from the 55EC9300 for the 65EC9700 how much noise reduction we can see on the 4K version depends on if the noise reduction processing is applied before the scaling to 4K or after the image is scaled. If the noise reduction is processed before the image is scaled the loss of resolution will be noticeable and if the noise reduction is applied after the image is scaled to 4K the noise reduction will be barely noticeable.

Of course, all of this is a non-issue if you sit 6' or further from the 65" screen as even Superman could not see the very minimal digital noise reduction that is undefeatable when the value is set to low.

Now here's the good news, from what I am told; digital noise reduction processing is done post scaling.

I'll post a few more popular questions that I may be able to add value to with the accurate answers shortly.

Any questions or comments?

Hello, Robert! Good to see you...is there a technical reason behind the WOLED tech being employed that prevents them from making it optional altogether? It otherwise seems like a stubborn stance for LG to take on an "issue" that could save them a lot of headaches from the anally retentive among us.

[vinnie97]

Right, I'm already aware of the RGB vs WOLED differences and the commercial and practical advantages of the latter, though I don't think it is fully refined (poor grayscale uniformity on my 9800 resulting in some unevenness near black but fortunately visible on rare occasions for the most part). However, I like it so much that I'm ditching my ZT60 in hopes of getting the 65 or 77" in the near future! I was more recently interested in the thin veneer of DNR that LG has hardwired into the 9300 and the associated maniacal squawking in response to the HDTVTest and Consumer Reports reviews.

It just seems LG has a history of implementing hardwired DNR across multiple product lines, and I haven't heard of any reasonable justification for it. It seems to me it would take a (simple?) firmware fix to address this "malady" and silence the loudest critics over what amounts to little more than videophiliac minutiae.

LG shouldn't be singled out for undefeatable DNR.

I was at a Worst Buy a few weeks ago...and not making this up(and probably accounts for the majority of the DNR)...

"OLED is just a fancier LED..."

A clerk should be immediately fired for stuff like that.

Hi Robert, happy to be here and thanks for the invite.

Like Vinnie (hey Vinnie!), I'd like to know why LG appears to have this obstinate stance on non-defeatable DNR.

Like most others that have seen or own the LG OLED, and despite thinking of myself as a pretty discerning viewer, I've never seen evidence of it in actual viewing in-store or even at the shootout. However now that the pixel peepers have released zoomed in pictures, you can see the circuit in action despite the fact that at viewing distance you can't. I've never been a pixel peeper and don't get overly concerned about the minutiae.

My real concern is, given what appears to be the fragility of OLED's future, that OLED could develop a bad rap for something so trivial. We don't want to see the general public walk away from OLED with some of the inane fears they were told about plasma (you need to refill the plasma 'gas', burn-in is inevitable etc.)

It 'seems' like such an incredibly easy engineering task to provide a simple on/off switch for DNR. I think many of us would love to know if there's some inherent issue that's preventing LG from doing this or, better yet, that they're working on a fix.

We really need to get this off the table not only to silence the anal retentive among us, but to give the owner a choice.

[Ken Ross]

Yes Robert, please ask about the latest ETA of the 77" UHD OLED. Thanks

[Robert Zohn]

Ken, will do. As of my last update they are still on track to release the first allocation of 65" EC97000 the week of 11/24 and 77EG9700 are one month later, so end of December.

I'll get an update at our LG dinner meeting this Thursday and post what I learn.

Hi Robert, thanks for setting this thread up.

I've been reading reviews on OLEDs as I find the PQ in terms of black levels, colour saturation etc. truly does make it the next evolution in display technology BUT one area which they seem to fall down in and surprised me was motion resolution.

Why is it OLEDs at present can only match LCDs in motion resolution without motion compensation technology?

I always assumed motion resolution would match Plasma, if not even exceed it in clarity, yet it's nowhere close. OLED was meant to take the best of LCDs and Plasma and exceed them, yet it seems there are issues at certain holding it back.

I'm just hoping this is part and parcel of the inteo phase, and future generations will be what we've always envisaged in a 'perfect' package.

Part of the issue with OLED...

What happened to all that DuPont tech?(which is now copied by Kateeva)

Is printed board ever happening? If not, that was one heck of a lot of industry money down the drain.

In "other OLED news"...

Philips is ready to start shipping OLED headlights to the automotive sector...

The state of play in the OLED marketplace as I see it. LG Display has ramped up production of WRGB panels and is supplying several Chinese manufacturers as well as LG Electronics with OLED panels.

LG Electronics has admitted they cannot satisfy the demand for OLED displays.

Samsung, Panasonic and Sony, noting the demand for OLED displays are all scrambling to get back into the consumer market for OLED displays. The OLED Alliance has been established by LG Display (not LG Electronics) and they (LG Display and the Chinese manufacturers) have been joined by Panasonic and Sony.

Samsung and LG Display have settled their legal disputes out of court, paving the way for Samsung to adopt WRGB architecture for consumer OLED displays. It is unconfirmed, but likely that Samsung will license the tech from LG Display which controls most of the patents.

Panasonic and Sony are more likely to purchase LG Display OLED panels for their consumer displays.

The question is, how soon can Panasonic, Samsung and Sony roll out consumer OLED displays?

While we wait, LG Electronics is dribbling their OLED displays out at premium pricing to skim the high end buyer.

If what you say is true that LG Display can't meet the demand for OLED displays, then how can you also claim that LG Electronics is "dribbling their OLED displays out?"

If the production can't meet the demand then clearly they're pushing them out as quickly as they can make them. They are pricing them at a premium to try and control demand, but they're by no means limiting supply to increase prices.

LG Electronics can't meet demand, not LG Display. LG Display produces the OLED panels used by LG Electronics and several Chinese manufacturers.

The article you posted says that LGE actually aims to sell more OLED tvs than LGD says it can produce.

If you what you're trying to say were true, that LGE was keeping consumer supply low to keep prices up, then LGE would be selling fewer tvs than LGD could supply.

LGE will actually have to buy 200k panels from manufacturers outside the company in order to try and meet consumer demand for its televisions.

You've shown nothing that indicates LGE is restricting supply to inflate prices, in fact, you've shown quite the opposite.

I see that the Picture Menu has an option for either Standard or Wide Color Gamut. Which one is best to select?
