It wasnt that long ago that LCD was completely useless in daylight. OLED has the advantage that the individual pixels emit light themselves without relying on backlighting.

The technology is still relatively new but expect it to be the norm for displays in the comming years. OLED HDTVs will be far cheaper than current LCDs of the same size.

8MP display? I dont see the point.

Relevance? OLED displays give an incredibly wide gamut, accurate
colour, dynamic range and contrast ratio in a versatile and compact
package, with a low power consumption.

It will not be long until they knock the pants of LCD displays.

Interesting, but who is going to be worried about what the back of the TV looks like? (Quote: "Also, the rear panel combines black and mirror-like metal surfaces, which together with the balanced front and side design completes its sophisticated overall appearance.")

Several years ago Kodak had an OLED display on one of its production cameras. They have invested heavily in OLED research and are licensing many companies around the world to use their technology, including Fuji.

Here's a report from another site that DPR doesn't allow links to.

Kodak broadens its participation in OLED Technology : Having pioneered production of the world's first full-color, active matrix organic light emitting diode (OLED) displays, Kodak today announced that it will broaden its participation in the OLED industry in order to further promote the commercialization of OLED technology. OLED technology is enabling a new generation of small and large screen display devices. To facilitate the company's move, Kodak has granted full control of SK Display Corporation to Sanyo Electric Company. Kodak and Sanyo formed the SK Display joint venture in 2001 to manufacture OLED displays. Kodak will continue as exclusive licensing agent on behalf of Kodak and Sanyo for certain OLED intellectual property.

You could look at your slides on a big screen as soon as you had shot
them?

Sorry, but your question has nothing to do with anything. It's like you are asking me how I feel about the weather in China.

Yeah, yeah ... digital is great ... but what's wrong with wanting to see the images right away, and on screen as big as slide projection screen ?

You're saying we must choose, forever ?

Quite possibly the technology is moving along well, and soon we'll have both.
 
AFAIK OLEDs had few problems. The main one was blue LED lifetime:

Hope Sony has solved it.

A few things in that artical are not 100% correct but with regards to the lifespan, i dare say thats something that alot of research is being put into.

You have to remember that blue LEDs in any form are the most recent addition to the LED family and it was only about 15 years ago that the very first 3mcd blue LEDs where introduced. We now have a vast array of blue standard LEDs and other colours which use a blue LED with filters such as white and purple (yellow and red filters respectivly). We can now get LEDs in almost any colour that are far to bright to look at.

The life span of blue standard LEDs is still a little less than that of their red, yellow, green cousins but it is catching. Thus it will only be a matter of time before OLED catches up.

It only took 3years of plasma development to up the half-life from 10000hrs to 80000hrs after all. :)

As I understand the biggest problem in OLED is that since the different colors loose brightness at different speeds, the color reproduction changes.

For a TV this is a big problem, especially since one would expect a shiny expensive stylish TV to last for a little while.

Different thing for a laptop. Many laptops don't get older than 2-3 years anyway and color accuracy might not be the biggest concern.

Maybe they expect a tiny TV not to be used for long hours, so lifetime is less an issue.

the lifetime is less an issue for crystaline LED than for orgnic. Same thing as with colar panels...

We can easily expect laptop is used some 8 hours per day and some 300 days per year and it makes 2400 hours per year. The given article states 1000 hour life for blue OLED. Even if today is made significant progress and blue OLED lasts 5000 hours it seem too little for me.
I do not know actual figures. Maybe the progress is much bigger.

Hm, well I think your figures are a bit eccessive. I am using my laptop a lot (and it shows - after tlittle over two years my 2.5k$ fujitsu pro laptop shows very very serious wear with two keys failing....)
But seriously I am not close to your figures...

Anyway you may be right - even if only living two years a laptop might get more use hours than a tiny TV would. Then again a TV could be on 16h a day without a screensaver or things alike...
