Despite hype from TV makers, the always-around-the-corner screen tech may never catch up to LCD, especially in price.

Price is definitely the greatest issue to adopting OLED displays (both for televisions and monitors). That said, I havent heard of any other technology to come close to OLED's contrast capabilities...and IMO, that is going to keep manufacturers motivation to drive cost down to attainable points for consumers. Would I spend 500% more on an OLED panel than a plasma (RIP) right now? Absolutely not. Would I spend up to 50% more for an OLED over a leading LED? Most likely.

I think one problem is that a 55 inch TV doesn't need to be curved, maybe an 80 inch, but not 55. They're just taking an unnecessary step there in manufacturing that's creating more expense.
I don't know how more recent models compare but I've had a 55" 7000 series samsung led/lcd tv and it's beautiful in lighted scenes but the moment the scene gets dark; backlight bleed on the edges. This is the main reason i would want to switch to an OLED, for the dark scenes, nothing else compares.

OLED is a pinnacle of surface based display technology being an emission display with each pixel self illuminating allowing the very large contrast and massive colour gamut that cannot be rivaled by LCD's. a mixture of the contrast and large colour gamut is the main reason for the displays appearing so saturated since we simply are used to displays that have faded colours and very poor contrast in comparison.
Production techniques will only improve, this is no different to when LCD's first were released and a 50in LCD would set you back for the price of a super car (around 150,000) when they appeared, OLED is comparatively far cheaper for the pure quality of the display.
i think LG's technique of using pure white OLED substrate with a colour filter in front is the most production efficient currently as only one chemical is required in the process.

Just due to their chemical nature, OLEDs are a whole lot less stable than their metal/metal oxide LED counterparts. Have they figured out a way around blue OLEDs from degrading faster than reds and yellows? IMO, since we keep TVs around a lot longer than our cellphones, OLED should just be restricted to "disposable" electronics

Blue OLED diodes in the newer generations achieves 62,000 hours of usage rating (compared to 198,000 hours for the green) - none the less, that is 7 years of 25/7 usage.

I agree about the need for a curved display in the 55" range, however, I was talking to the audio / video manager of a local A/V shop, and he told me that the reason the screens are curved is not what us consumers would expect. It is a structural issue - the curved screen makes the display more rigid. He said that he was told this by one of the manufacturers at a recent show. Amazon has LG's 55" flat OLED TV, but it is more expensive than the 55" curved.
LG is making a big push into the market for OLED TVs. Their 55" curved OLED TV has dropped about $10K since it first appeared in the US market. It is only a matter of time before OLED TVs reach price parity with LCDs, and with manufacturers like Panasonic working on large (55") 4K OLED TVs that are printed, I believe the cost will drop much faster than it did when large Plasmas and LCDs first appeared on the market.
The person who wrote the article is saying the same things that were said about large plasmas and LCDs when they were first introduced. Look where they are now.
In no way can LCD, or even plasma complete with OLED in terms of picture quality. Plasma is great, but OLED is better.

It is different because the White OLED sub pixels are actively controlled, unlike an LCD where you have a uniform or section dimmable backlight and an LCD matrix infront of it which limits the light through it and filters the colour and sections the backlight into sub pixels.
The colour filter is passive while the OLED sub pixels are active producing far greater viewing angles, contrast and a wider colour gamut.

Not upgrading again before I can get 4K OLED in at least 70".
As a gamer I would -love- to have a UHD OLED monitor - and as a movie freak I dream of a +70" 4K OLED.
Eveytime people see a movie clip on my Note 3 they notice the quaility of the colours and depth (due to the black levels). OLED displays has the best static contrast, super wide colour gamut, low power consumption and low latency. They are better than the best plasma ever was (Pioneers KURO).

Price isn't the only problem facing OLED. Last I heard they still suffer from both severe burn-in and from a short life-span primarily due to the blue chemical degradation problem. Plasma continues to be the best alternative to LCD. It's a shame Panasonic exited the plasma market. They made some of the best large 3D sets.

I do not care about the 'curve.'
What I want is a display with TRUE 10 000:1 or better contrast without backlight bleed-through or any obvious backlight or color uniformity issues. Most LCDs on the market today do not even break 1000:1 contrast, have fairly obvious bleed-through and non-uniformity when displaying a mostly black screen in a dark room.
OLED will displace LEDs eventually. Sorting out all the mass-production challenges is just taking longer than the industry originally expected. Once everything is sorted out, OLEDs should become cheaper than LCDs and LCDs will become mostly history.

It's so bizarre how they keep pushing curved displays. Who asked for those? What I personally want is better image quality.4K is another strange tech driver...
They did the same with 3D. Appearntly the old marketing system of find what people want and sell it has changed to make something then shove it down ppls throat untill they like it....
Lucky for me I go the plasma way, even If Panasonic and Samsung goes out of that market, ill just start buying LG. Who knows, maybe LG will be able to improve their black levels and Input lag, and then get a killer TV.

Hours of usage rating dosent mean anything. You still only get 2 years on your TV. If it dies after that, noone will care for the "Estimated life span".
