It's not the only thing, LCDs have much higher brightness than OLED, which you need to make best use of HDR, which is the next big thing.
LCDs don't do true black. That's why there are two standards for HDR TVs to qualify as HDR; one with higher maximum brightness but also higher minimum brightness (LCD) and one with a lower maximum brightness and a lower minimum brightness (OLED). The spread is similar, but LCDs suffer from various subtle defects to get down to their minimum brightness. And it's still nowhere near true black. Whereas OLEDs measure zero when the input signal level is black. In practise it seems the maximum brightness isn't a big deal. OLEDs have suffered problems with uniformity at very low levels in the past but they seem to have been almost eliminated with the latest TVs from LG. |

Current OLED TV's (all using LG panels)
LG Panasonic Skyworth confirmed to release an OLED using LG panels in the future: Phillips (later this year) Bang & Olufsen (2017) |

^^ Me neither, I've not yet had an example of a picture, that I thought was too dark and needed to be brighter. Everything appears as I would assume the content maker made it to be. The great thing about OLED, is that even when the picture is very dark on purpose, I haven't felt the need to lighten the picture to be able to see it.

My dilemma is i want to keep next tv for at least 6-7 years so if i spend 3k or over then its got to be future proof. Then there is the question of oled or led. Is paying an extra 1000 or more for oled worth it. Take this tv. https://www.google.co.uk/url?sa=t&so...-8Agd3HSPNCZpw other than one been oled and the other being led what are differences that make the oled tv £700 better?

It's really a personal decision - and my personal decision was to buy an HD LCD set, as there's no 4K content worth mentioning yet, and not likely to be for a good few years (if at all). So why not buy a decent HD set for now (and save buckets full of cash ), and see what the situation is a few years down the road - such as is there much 4K available?, have OLED sets proved reliable?, and have their prices dropped?.

Do they?, I can't say I was aware of that.
Whereas there is a separate spec for essentially the OLED sets that can go much darker but won't go anywhere near as bright, this is over 540nit and down below 0.0005 nits. Other things come in to play to but that's the btightness side. Load of info here. http://www.trustedreviews.com/opinions/ultra-hd-premium |

You're making assumptions based on the use of the word "organic". It merely means the compound used is based on carbon atoms. Organic decay is not necessariy implied, but of course there may be other ways the compound deteriorates.

As usual buy what you want from somewhere with a free or cheap 5 year warranty and forget about it, there will probably be something else you want by then anyway. |

The life of OLED panels isn't known, neither apparently is the life of LED backlights.

Are you people trying to be obtuse? OLED colour change decay is already infamous. It's only 'controversial' in the sense that the two specialists who make them make light of it, against the findings of the rest of the world. These manufacturers even put up a .org website and paid for it to stay no.1 in search results because of it- search for OLED color degradation and see it's Manufacturers v. Rest Of World.
¯\_(ツ)_/¯ |

No more, please. But I will google since you can't be bothered to cite your own. |

Seems historically there was a problem with OLEDs, but appear to have been addressed. I found old articles discussing fading and burn in on AMOLED screens on mobile phones, an article saying Tim Cook (Apple CEO) doesn't like those displays (probably a poke at rival Samsung phones), scientific papers discussing the mechanisms of the decay and how it's worse for blue OLEDs, and a website discussing how problems with the lifetime of OLED are myths and some other myths about OLED.
So, I have to admit there's a possibilty you may be right. I'll get back to you in 5 years to let you know how I'm getting on. ![]() Thanks so much for your gracious input. There are friendlier ways to discuss topics without being so combative, you know. |

Nice TV, though I didn't go for curved myself. I think it's a bit of a fashion fad personally. YMMV of course.
I set up the TV with the 4K Blu Ray player (Panasonic DMP UB900) at the weekend. And I'm impressed. Bright highlights, especially noticeable in high contrast scenes, as you'd expect. I only tested it with San Andreas (it came with the player), I don't whether that's regarded in any way as HDR "reference" material, but it did look particularly good in the scenes with bright patches of sunlight and everything else largely in shadow. Pity I can't say the same for the story though... There were motion issues (odd intermittent judders - not the same as 24fps juddering) till I turned off "Clear Motion". So far so good. |

Unfortunately that tv only comes with curved. Thankfully it's only a slight curve. Curve does nothing for me to be honest. Not sure what the point of it is since it offers nothing.
I would not have gone so far up the range if there'd been one with those specs and a flat screen. There were a few things I didn't need, like the Harman Kardon sound system (because I already have an AV amp). I did want 3D capability though. |

Exactly. It distorts the geometry of the image that the filmmakers produced. Cameras and lenses are designed to produce a distortion free image on a flat screen. You would have to sit at the centre of the curve to get a distortion-free picture. I never understood what the benefits were supposed to be. It's just a marketing device.

I've read about some people taking USB sticks with content on it to see what the tv they're interested in looks in stores. How do they get the content on there and this there some website to download 4k samples?
