OLED 55inch goes on sale...
late8
02-01-2013
LG are putting a 55inch oled tv on to the UK market for a tidy sum of £6300 !

Question is who or will anyone buy one?.

From what I have seen of OLED they still have real issues with...

Over saturation
Screen burn
Short life
Poor white valance (blueish green)
Viewing angle fade

Which means anyone looking at this picture / price category will go with plasma or projector.

The issues that you've listed there aren't really a problem for OLED displays. The real issue with them is the expense in manufacturing them. They certainly do not have a short life - to the point where LG & Samsung are near giving a lifetime guarantee (not exactly but the maths works out with the number of hrs etc it's a long long time!)

The other issues just don't exist at all.

Production costs are going to be high for the time being, but that will change within 2 years when OLED R2R manufacturing procedures are developed in full.
Reference http://oledflexible.net to see what I mean about the manufacturing & when we'll expect to see consumer units hit the shelves.

The large OLED screens will be somewhere in the upper region of affordable for some time, and you'll be seeing much smaller mobile devices with true flexible OLED displays by then too! (see Brian Berkeley of Samsung's presentation on Youtube)

Anyway - I'm new here and found the place through a google search so I should probably say hello too! I'm Joe - glad to be part of a rich & diverse forum!

Welcome it will probably be like plasma in years to come with prices falling I can remember crappy Goodmans sets costing 4K

Yep, no different to any other new technology that's new on the market.

I remember seeing 40" plasma for £12k when first released, not even HD ready spec. Pioneer were asking nearly £6k for their 50" displays only ten years ago.

My set is over seven years old now, hopefully it'll last just long enough to see OLED prices fall a bit, if it does I'll definitely be looking at one.

AMOLED displays won't remain at the same crazy figures that plasma & early large LED displays maintained for that same length of time. (I know it seemed like they dropped in price quite quickly, but actually they didn't for the high-end stuff.) When they go full swing in production it will be because they really have honed down the manufacture process - and when they've perfected roll-2-roll it will be dirt cheap then.

The interesting thing happening at the moment is the legal battles going on all over the place with regard to this tech. and each company's rush to announce their display being released first normally is a sign that both are ready to either commit with a fantastic design or an absolute bodge in order to be first - I'm honestly not sure which way that will go. In the meantime OLED lighting companies are getting on with doing business selling their products - like with big contracts for things like Paris Metro.

Anyway, that's a tangent, and a long-winded way of saying I expect OLED to be affordable reasonably soon after introduction (usual first gen standard stuff aside of course).

PS - thanks for the welcome

I would disagree - the absolutely colossal development costs (it's took a GREAT many more years, and mutli-millions of dollars, to make it work than expected) mean it's unlikely the development costs will ever be recovered.

The only way to minimise their loses is to keep the prices as high as they can.

I would agree there's going to be a LOT of expensive legal battles going on the years to come

Plasma and LCD development also took many years, and the costs were also huge.

I suspect a sizeable fraction of the OLED development cost has already been recouped from its deployment in smaller displays.

The development of both of those were far faster, and only a tiny fraction of the cost of OLED.

The massive development costs I mentioned aren't to do with small displays, small displays were 'relatively' fast and cheap to develop.

The theory was that it was 'just' a question of scaling the processes from the small ones - but that didn't prove to be the case, and it's taken absolutely massive sums of money (and many years) to make larger ones at all.

Very much doubt OLED was even thought of in 1964 which was when serious development of plasma began. It was 33 years later in 1997 when Fujitsu released the first 42" colour plasma with 852x480 resolution, this was shortly followed by manufacturers Phillips, both cost $15,000 each.

Likewise, the first LCD display was produced in 1964 (following many years of academic work on liquid crystals). The inventor, George Heilmeier, was convinced that large flat screen colour displays were just around the corner. In reality, it took another 9 years to get to the first product (a pocket calculator), and 24 years before the very first active-matrix TFT colour display was demonstrated.

The first very large displays were PDP rather than LCD, so there were clearly additional scaling problems to be overcome. It's been a long and expensive road for LCDs too.

[Intriguingly, the UK research programme into LCD flat panel displays can be traced back to John Stonehouse (then Minister of State for Technology) in 1967. He learned that the UK was paying RCA more royalties on the shadow mask tube than the development cost of the Concorde, and was keen that we should seek a solid state alternative! This research produced the first commercially usable liquid crystals—cyanobiphenyls.]
