OLED TVs: Technology Advancements Thread - Page 175

Another year without OLED...I only know the Sony 11"

I don't want to sound rude here but they've had that on their website for a little over a month, maybe longer?

It's nice information though!

Yep. In the heydays of USENET, the nested tree-view of a thread allowed you to visually ignore large digressions in a whack. You go from OLED to, (picking somemthing out of the air) USENET, and never impact the rest of the conversation.

By the way, how do the wires go from the base up to the panel again?

They still have this old obsolete page also: http://www.lg.com/uk/tvs/lg-55EM960V-oled-tv

Well that convinces me

Samsung Display drops injunction against LG OLED Display

"SEOUL, Feb. 12 (Yonhap) -- Samsung Display Co. on Tuesday dropped an injunction aimed to block LG Display Co. from using its organic light-emitting diode (OLED) technology, raising hopes the two rivals are moving to settle their display technology dispute."

With the Korean government pushing the two companies to cooperate, OLED is likely to evolve faster.

Faster than it would otherwise yes, but not much faster than predicted by many here, because the bulk of the obstacles in the way for OLED weren't expressed here as legal, they were economic/physical.

OLED is massacred and bulldozhed - it's real or just Samsung-blasting?

Honestly, I think Cook is Samsung bashing. He's also proving to be a bit more Jobs-like than I recently gave him credit for.

The points about power consumption are true on mobile -- up to a pretty limited point. The points about color are true -- up to a pretty limited point. But the guy used the word "awful". The word that comes to mind for me when I see an S3 is "beautiful". And I use an iPhone 5, which has a very nice screen of its own.

I've got an S3 and my wife an iPhone5. I much prefer looking at videos and pix on the S3. It's has more of an impact and is simply more 'fun'. With that said, I don't give it high marks for color accuracy, but I don't think that was ever Samsung's intent. In-your-face color sells well in the mobile world and this is an example of that.

I've said on several occasions that if an OLED, with its super-saturated colors, were calibrated to conform to Rec709, would we see any difference (in terms of color) between it and more conventional displays? OLEDs may shine with new standards and their expanded color gamuts, but I suspect other display technology might rise to the occasion too.

You may be right, but the way I look at it each company has bits of the technology puzzle, and their own connections with other fabricators. Pooling their resources might make things go faster.

And I remain optimistic about Panasonic's and Sony's cooperation.

I am VERY curious about more specifics about impulse-driving in relationship to LED and OLED technologies. OLED is initially a fail for motion blur during video game use, unless it's got enough brightness for low-input-lag impulse-drive modes. OLED has a lot of brightness problems (unlike discrete/crystal LED's) Does anyone know if any OLED manufacturer plans to release impulse-driveable OLED's that can run at full brightness even in impulse-driven modes (as quickly on-and-off as CRT phosphor)?

To the best of my knowledge, Sony's expensive Crystal LED prototype is definitely impulse-driven as it flickers in camera video. It is also reported to have great motion quality. (unlike PS Vita OLED which has lots of motion blur). Does anyone know what the impulse length (length of pixel flash per refresh) the Sony Crystal LED is? Has anyone ever pointed a 1000fps+ camera at the Sony Crystal LED, to determine its refresh pattern? (I've already created such a high-speed video for LightBoost LCD's, measured to have 85%-92% clearer video game motion than a typical 60Hz LCD -- that is 7 to 11x less motion blur, thanks to impulse-driving)

Hmm. This is the same company that just hired away one of LG's OLED experts????

Leaving aside the fact that Sony will never ever ship a crystal LED, the prototype had terrible motion quality. Because of whatever kind of "scanning" technique it was using, it would "draw" the image vertically and the result was flat out awful on the edges of the display. They showed a boat floating across the screen and unless you were blindly ignoring it, you could see it "combing" into view. I found it odd the thing got such hype given how flat-out awful it was at display horizontal motion.

Again, this matters not at all. No consumer product based on this technology will ever be delivered. Sorry.

Thanks, that satisfies my curiousity. Sounds like it is using a rather bad scan pattern (perhaps made necessary in the prototype for some reason, such as a requirement to multi-scan the Crystal LED, etc).

That leaves OLED. Regardless, the solution to the motion blur problem for OLED is not as simple as many think...
instant pixel switching (alone) does not necessarily eliminate motion blur; the only way to do so is to shorten the length that an individual frame is displayed (either via extra frames, or via black period between frames)

For what it's worth, all LCDs do this as well. I am surprised that they were not scanning at a rate high enough to at least bring it down to LCD levels. Or maybe the motion resolution just made it stand out that much more. Or perhaps simply because it was a very early prototype or something that is unlikely to go into production.

I wonder if OLEDs are updated progressively like Plasmas, or scanned like LCDs.

Two different FAQs on the same site. Which one is newer? The "oled-tv" one has been around since at least CES. The "oled" one does not have "burn-in" and "weight" entries.

That is true, but the speed of the transition of the pixels is a problem for LCD and to some extent for Plasma.
If panels could run at 120 HZ (in the US) as it is a natual multiple of 24 and 60.

I, like many, am so used to 24 HZ for movies that better motion does not look right.
30HZ would be a better choice though.

The reaction to the Hobbit's 48 HZ was mixed at best.
I wish I had the time to see it.

When the said company CEO says: “If you ever buy anything online and really want to know what he color is, as many people do, you should really think twice before you depend on the color from a OLED display” and does the above, the only logical explanation is they are working on AppLED which will be very finest OLED in contrast to rotten LG and Samsung OLED .

Without color management, OLED saturation is terrible. That's why Apple is focused on LED displays - their saturation falls in line with the sRGB spec so they get accurate color for "free".

Apple will claim that they perfected OLED and that is why you will have the privilege of paying three times more for it, than the competitors products.

They have that King's New Clothes sale pitch down perfectly.

No, don't overstate it. It was mixed, not mixed at best.

Too true. And they compel you to only go to their own Tailors for everything.

But I think you mean the "Emperor's New Clothes."

People need to realize the burn-in issue depending on their type of use. It's not something that should be overlooked.

I did not try to state it.
The review I read were mostly bad.

What would the price of an OLED TV be if the yields for the panels were as high as they are for LCD panels?

Reviewers tend to be overly critical. On the Dutch HTforum most folks seem to like The Hobbit 3D 48fps. 90% of viewing is 2D anyway so 3D 48fps reviews are not really significant.

"Mostly bad"? Not the ones I read. As a guess, you may be reacting to headlines. When something is new and sold to be 100% accepted by everyone as great, the bad reviews will always float quickly to the top because they are the most sensational---it was such a surprise for anything bad to be attributed to this new technology that it quickly had the spotlight. Look at the overall review set from independent places like RT.
