Now you're just arguing semantics.

Your interpretation of the word 'upcoming' is clearly different to mine.

And the dictionary's...

Haha, I'm not even going to bite.

Bonjour · 31 Oct 2009 at 19:44

Emerging? Yes. Up-and-coming? Definately.

Upcoming? Not really.

Looks sweet. The future definately.

Thank you, I learnt something new today

So what's so great about the OLED stuff then?

I guess the key thing about OLEDs is that they produce their own light. Therefore they do not need a backlight (as shown by the transparent screen pictured above) and therefore the power draw is much lower than a regular TFT screen, the contrast is superb as there is no light bleed, they can be viewed from a very wide angle, the colour quality is more vibrant than a TFT without being harsh.

Come to think of it, all the current benefits are listed here: http://www.sony.co.uk/product/tvp-oled-tv/xel-1

£3,399.99 from my local sony centre lol , thats for the 11 inch oled. I agree with it being upcoming because once its truely accepted as being the next generation of tvs it'll be like flat screen tellys today.

The only problem that i see with OLED is that with any bright sunlight in the room and they fade badly. Obviously you can pull the curtains but in the summer youd have to have a dark room im sure..

Hopefully they'll have it sorted. The OLED phone I had was like that ; I know it's a phone but it's the same tech . It was amazing when it wasnt sunny/indoors ; going outdoors even with the sun in wasn't good at all.

:-/ hope they do fix it, my TV faces out to my windows and my curtains are thin as hell!!!

15" OLED This Year
20" OLED 2010
30"+ OLED from LG in 2011
40"+ OLED in 2012

they will still be “fairly expensive”.

Kim forecast that LG's OLED TVs won’t cost less than LCD screens until 2016.

He said that price reductions will come as the result of a 20-30 per cent drop in material costs, achieved through switching to more cost-effective OLED panel production methods.

I think that these babies will drop in price faster then LCD's!!!

So how well are these theoretically able to calibrate? Black depth, contrast ratios, colour accuracy, etc? Anything posted anywhere regarding this?

milkinc13 · 2 Nov 2009 at 22:18

if it's as thin as the sony tv it will look brilliant with a decent sleek case, with that contrast ratio's will be to large to calculate so colours will look how their supposed to.
Just need screen sizes to go up and prices to go down.

One would assume, hopefully not making an arse (ass?) of you (u?) and me, that with no backlight black depth would be near perfect - only interfeared with by ambient light and light from other OLEDs in the screen.

what are your thoughts?

I dont understand. Is that supposed to look good? Looks like a washed out, grey, blurry image to me :confused:

yeah doesn't look good but for a start if it's blurry then it's the photographers fault..then you've got reflections etc. look just behind it at writing imo a ***p taken pic but in the photographers favour not easy to take when you have a person in front of it reflected lol.

Guest2 · 3 Nov 2009 at 15:38

^ emmm. Looks like a blurry hologram to me. Suppose it is hard taking pictures of monitors with images on. Ill try it tonight with my new dell screen and see if i can bodge it up as much as this photographer with a canon powershot i paid £40 for

Here's the big problem with OLED.. Apparently the lifetime on blue can be as low as 11,000 hours. That still works out at 458 days of constant usage, which could be fine for a device you're only using a few hours per day, but if it's something you leave on then it won't last so long..

In general lifetimes are published for full power or certain specified conditions so actual available lifetime could be longer.

And neither do they tell everything about LCDs:
Monitor manufacturer then have the possibility of customizing their panels. They have several basic electronic component sets (sometimes customizable) and several qualities of backlighting...
Pixel command components and backlighting quality, however, is never disclosed. In fact, the MTBF for backlighting control is always shorter than for the tubes. How much shorter? Nobody could give us a straight answer for this question. Once again, it varies according to manufacturer spending.

So don't expect cheap monitors with second rate components to have good durability.

However they have one blue component giving 50,000 hours ,why do they have three different components for blue?

You realise the CCFL backlight bulbs used in almost all the LCD monitors in use right now are rated much lower than 50,000 hours right?

LED backlit screens last longer however...

The two are not really comparable because the compounds in an OLED screen degrading at varying rates will throw the colour balance completely out of whack long before the blue compound actually reaches the end of its life. I've no idea how long it would be before the imbalance is no longer correctable, but it's bound to be some time well before 50,000 hours.

CCFL degredation is no anywhere near as serious a problem; a screen getting dimmer is one thing, a screen that starts showing everything with a yellow tint is quite another. And as most monitors have vastly overpowered backlights anyway the dimming is correctable for a while, just bump up the brightness control.
