No Sony OLED Displays In 2004
Anonymous Howard writes "Designtechnica is reporting that Sony will not introduce any OLED displays in 2004 as previously anticipated. Sony was planning on producing 300,000 2-inch OLED panels per month for its portable devices such as DSCs (digital still cameras) and PDAs. Surprisingly, there have only been a handful of products out that use OLED displays; Samsung has a cell phone and MSI has an MP3 player, for example."
I've had a pioneer CD Deck for my car for almost 2 years now that has OLED

Come on folks- this is the internet.
On a side note- I dare you to
On a related note, in its 2004 MiniDV camcorders of the HC-XX series Sony claims to use a "Hybrid LCD display" which is claimed to perform significantly better than the regular LCD screens it renders obsolete (like the one in my 2003 MiniDV). I tried to find out what Hybrid meant and failed - what is the big secret I wonder...
See that long UID - that's what you get for lurking too long
You're right about the lessened life compared to LCDs, but you're wrong about the production cost. OLEDs are cheaper to produce than LCDs, this is a known fact.
:)
There is also many other advantages compared to LCDs; Organic light emitting diodes are self-emitting and don't require a backlight, they're brighter and require less power than LCD displays. They can also be read from a much wider viewing angle than LCDs, and they can even be made on plastic instead of glass.
I sure enjoy the OLED display on my mobile phone

... Because of vested interests.
;D)
OLED holds many promises because it is, as the name indicates, a LED type of display. In other words, you don't block/filter an underlying lightsource like with LCD-type screens. Every pixel itself emits light. This makes for better image quality at higher resolution and less power consumption plus, as a bonus, no vulnerable, ill-distrubuted central light-source.
Once (if?) the optimal solution is found to creating the seperate Organic colors reliably (and currently the biggest problem: durably) OLED should overtake all other techniques. Especially since some production techniques currently being pioneered do not have an inherent limitation to the substrate size (read: Mega sized displayes at Giga resolutions, ultraflat, high light-output and low power...).
I say should because LCD is currently the entrenched technique and I don't think all investments have been recoverd yet. The question then becomes: is the best (cheapest to produce) OLED solution being brought forward by a current player with LCD 'capital' to defend or an outsider? If the latter, OLED has a fighting chance, if the former, we'll have to see if several producers have competing designs to make OLED still take off. A lot of money has gone into those factories, and even if they are relatively easily converted to OLED, most companies don't jump for joy at the prospect of destroying existing investments for a newer technology. (Or any new investments for that matter
Recouping costs may hold OLED back more than any technological hurdle, I'm sorry to say.
Karma? What's that again?
...because in a relatively short time, that gorgeous picture will have faded considerably.
They're making great advances in battling this problem, thankfully. In addition, Kodak does offer a full warranty (last I checked) on the digital display components.
there was an article on Bloomberg TV's asia market report the other day stating that there is a massive overproduction of LCD's and buyers are not buying so prices will fall as a result
good news for LCD buyers but bad for those of us waiting for mass produced OLED's
gotta buy the old stock before getting the new as usual and the less you buy the cheaper its gonna get for LCD's (forget plasma as it degrades dramatically in 3years)
OLED displays can also support much higher (than LCD) refresh rates. Because there is no backlight, when a pixel is black it it really black so the contrast is also much higher.
30 years if of course too much, LCDs dont last that long and about 5 years should be good enough. Keep in mind that they do not die the day they turn 5 y.o., they just lose some of the brightness/contrast.
So maybe I'll get some mod points for this (makes up for maybe losing my job on Monday. :)

Note the descriptions on the specs page, no where does it mention OLED, but LCD is everywhere.

The OLED panels I've played with have all been far lower power than an LCD with the backlight turned on, but that's not a fair comparison for some products. For example, MP3 players can get away with turning the backlight off in many cases. An LCD with the backlight turned off takes almost no power. This "idle" state was hard to do with the OLEDs I've used because they were PWM driven, and below a certain brightness they'd get flickery. At the lowest acceptable brightness, they were using about 100 times the power an idle LCD did.
But OLED is still lower power for devices which are useless with the backlight turned off (like cameras, portable TV/DVD players etc). I wouldn't be surprised if next generation panels come down enough in power requirement that the difference isn't important.
Plasma just isn't dropping in price fast enough and I'm concerned about it's limited life.
Um, OLEDs also have a limited life.
(Although hopefully the price would be low enough that you could indeed afford to replace it every few years. But such a hassle!)
OLEDs are getting pretty big right now though I admit they are only prototypes - http://www.eetimes.com/sys/news/showArticle.jhtml? articleID=20600073
The durability will be overcome, I remember when labs were first playing around with the idea of OLEDs and they only had green colours and lasted for only 100hrs. Now the red and green last well into 20000 hrs it is just the blue that is failing to get up to spec. Last I heard they were just about to achieve 10000 on the blue - almost getting up to a useful standard.
Currently the fullcolour screens are a lot thicker and power hungry than they will be eventually since atm three layers for each colour are used with a mask - even so these screens are a -lot- thinner than comparable LCD panels. Hit google image search for "OLED screens" and such (i'm in work atm and they filter google image search) you will find a lot of prototype screens in profile *awes at the thickness (should I say thinness)*
They will be the screen technology of the future. No doubt about it - especially when a flexible polymer can be used as the substrate (currently glass) and we can all have relatively cheap, huge and flexible screens. They are so efficient and bright they are being considered as a new lighting system for airport runways - embedded OLEDs would mark the be the current 'white lines'.
They will phase out LCDs starting with phones, I am sure it is in nokia's roadmap to start replacing LCD with OLED by 2005/2006 (cant find the source again though)
Anyway OLEDs are great!
