Latest OLED-developements

Hey Roland: Freut mich dich wieder hier zu sehen. Dein Namensvetter.

I think that the arrival of OLED technology in PowerBooks will be a major revolution. Right now, I can get about an extra hour of battery life from my iBook if I turn down the brightness half way. With OLED, this energy saving would be much more significant.

I wonder how long it will take for OLED to show up in PowerBooks and iBooks. Introducing OLEDs before any other laptop manufacturer would be a great way for Apple to regain the innovation lead.

One more thing: How do you read an OLED display in the dark?

Also they're supposed to be much thinner.

Sein gutes, jeder nach so lang wieder sich zurückziehen zu lassen.

Its probbaly a little messy. Just learnin some german in school.

well, if i remember the acronym properly, oled stands for organic light emitting diode. so it lights up, it doesn't require BACKlighting though. as it emits it's own light.

Yea. It's like asking "how does an LED light up in the dark".

If I recall correctly, a major problem for color OLED displays is that the different color pixel elements degrade at widely different rates. (I can't remember which color goes first) but you end up with a display that is dramatically tinted towards one end of the spectrum. As battery life improves the savings to be had on the display's efficiency aren't so dramatic. New lithium-silicon/polymer batteries will cram a lot more energy into a given space.

OLED's may hold an advantage in cost if they prove easier to manufacture. LCD's aren't so easy to do well (one of the reasons they're still expensive) However, they've gotten much cheaper than they were initially, which leads me to believe that manufacturers have gotten better at making them. I've also read of a few technologies to make LCD production simpler. We probably can't write off LCD's as portable displays for at least another couple of years.

(i think)

I work for Kodak ( they invented OLED and hold the most patents on it ). Every once in a while we have 'future technology' presentations. It gives us 'regular' employees a chance to see what Kodak is working on. I have been to many OLED discussions. Most of the information I gained, I cannnot share. But I do believe you are correct that the blue fades about 4 times faster than the other colors. This is the biggest stumbling block of mainstream OLED usage. 4 times faster doesn't mean too much unless you know how fast the others fade. Out of memory ( so I may be slightly off ) the current blue 'pixels' fades drastically after about 1000 hours of usage. That equals ~42 days of straight usage. Not so good. Of course Kodak has been working on making this much better .To learn much more information on OLEDs, visit <a href="http://www.kodak.com/go/oled." target="_blank">http://www.kodak.com/go/oled.</a> To see what I do, go to <a href="http://www.kodak.com/go/digitalminilabs." target="_blank">http://www.kodak.com/go/digitalminilabs.</a>

I am very surprised Samsung is releasing an OLED monitor. I know many companies are ramping up production of various OLED products but the biggest size I have heard of to date is a 5 inch one ( these are mainly for pdas, cameras, video cameras, car radios, etc. ). Can you provide a link. I am also very interested in the price. I know Kodak has many manufacturing partners for the OLEDs since we don't have the ability to make retail quanities of them ourselves. I think Samsung may be one of them.

I remember reading in Scientific American a few years ago that one of the biggest potential benefits of OLED displays was that they could instantly triple the resolution of displays, since the red, green, and blue pixel elements were transparent, and thus could be piled on top of one another, rather than be placed side by side (relying on your eyes/brain to blend the colors).

That would be a quantum leap in display technology, giving digital displays photographic quality.

From Digit mag August 2001.
From a report form the Society for Information Desplay 2001.

[quote]...Sony has announced pians to develop thin OLED monitors. The company showed a 13 inch, 800-x-600-pixel OLED panel only sightiy thicked than a credit card. <hr></blockquote>

Wow I didn't know that. I do know Sony is Kodak's biggest competitor and threat in OLED space. I would love to how well it performs, how long it lasts and how much it costs.

Another problem with current OLEDs is producing a completely white image actually uses about twice as much power as an LCD. Luckily, it is not common to have a fully white image and it averages out so the OLEDs on average use much less power.

So you could save battery life by using a toned-down theme instead of the very bright Aqua :-)
