What's the big fuss about organic led screens ?

I have been told : much less power consumption, much, much better color quality...

 

Thinner, lighter, greater range of colors, better contrast ratio, faster response time, much lower energy consumption. What's not to like?

 

Except price

 

The millions of little LED's emit the light to make the image on the screen, but the LCD only filters the light from the backlight. This makes it obviously thinner, more power efficient because all the light it emits is used to display the image, and it looks better because. Each pixel is composed of three tiny LED's that emit red, green, blue, or no light which produces superior color and contrast to LCD's.

 

My next-next laptop will have an OLED screen hopefully, lol.

 

If you seen one in person, you'll understand where there's such a fuss over them. Dropped in a Sony Store a while back and they had a 6" version on display - it was absolutely stunning. Too bad it was $10000.

 

I was a little skeptical about OLEDs before buying my Zune HD. Once it arrived, and I turned it on, I could easily tell the difference, as could many of the people around me.

 

And the fact that organic LED's have a much shorter lifespan than your typical LED found in electronics. I think Microsoft said that the lifespan on the screen of a Zune HD was 5 years or 50k hours, depending on use. That's quite an investment on a device that I would think to use for longer than that. So much for re-sale value.

Additionally, some critics say that OLEDs are more difficult to see in direct sunlight, much more so than LED screens... which lead some to beleive that was the reason why Microsoft only showcased their Zune HD indoors... not out.

Some interesting articles:

Guess what I have an LED screen in my lappy but not OLED.
LCD is the technology used to "create the image" - and then you get CCFL and LED lighting.
OLED is different - but you should know that - and its not and LED screen.

Yes, they are nice, but not that special - and absolutely unreadable in UV light (part of sunlight) - I have a Sony X1060 which has an OLED screen - in bright sunlight I cannot read it a max brightness and in the shaddows its doable - if I place it in sunlight behind a car window (which has a UV filter) it becomes readable.

50.000 hours? That would actually make them exceed current LCD displays which will die after 30.000 odd hours (andused to last 60.000 hours) on average if I am not mistaken.
As far as I am aware the OLED lifespan is much shorter.

 

The lifespan of OLED worries me. Right now, it's too short to be practical. But the technology could still be improved, I have no doubt.

 

What % of laptops have OLED screens ?

 

0 percent.

 

But you don't have an LED screen, you have an LCD screen with LED backlighting. Calling an LCD display an LED display it wrong. That is like calling an LCD display with CCFL backlighting a CCFL display; it makes no sense.

OLED is just a type of LED. There is no other technology for LED computer screens other than OLED.

 

True, I have LED backlighting - and an LCD.

But they are still referred to as LED screens by many people - even if its just the backlight.

And when you speak about an LED screen no-one will think "OLED".

 

But do you pronounce it oh-ell-ee-dee or Oh-led. That's really what's important here.

 

OLED is still very expensive.. a Sony 10 inch OLED screen is $2300..some OLED TV is $11000+++... they are inpractical for now to have in laptops so you have to wait a few years before the tech comes in.. what's the fuss? I think its just the fact that its organic... so the LED's inside are greener.

 

lol..

I'm going to make sure my CPU is grass-fed too. None of that bad corn!

 

Organic, as in hydrogen, carbon, and nitrogen not as in tomatoes and carrots.

Honestly, if you don't have a clue what you're talking about, at least take a gander at the Wikipedia page.

 

What about the lifespan? Shouldn't it be... a' lot of years?

 

Sure, maybe the lifespan or readability in direct sunlight may be issues in the present, but OLEDs are still in an infant stage. The very nice thing about this technology is the flexibility of the screen. You can literally bend the display:

Because they can make one with a flexible screen doesn't mean it's an intrinsic property of the technology.

 

Oh it is, to be sure. I'm just going off what the article mentioned. I thought for sure LCD displays lasted longer than 30k hours though. Seems awefully short.

Convoluted never said it was. He merely mentioned that the nice thing about OLED technology was that you could make a bendable screen out of it.

 

If you think about it, 20.000 hours is quite a bit of time.
Its 833,3 days - so over 2 years of constant "on" - 30.000 is then nearly 4 years at 1250 days.

And all the time you sleep, or your laptop goes into batter saving mode... switches off the screen - that saves a lot of time too.

 

No, he literally said that the nice thing about it was that the screens are flexible and that you can bend the display.

 

and he's right. that's one of the nice things of them. and you can do it with each and every of them, but most will still stay in fixed form at the beginning


btw, for anyone who still doesn't understand the big thing about oleds: they light themselves. no flat screen prior oleds does that, all use backlighting. what that means: a black oled pixel costs 0 power, a black oled pixel will never die, and a black oled pixel is as black as it can be.

so if you want to save power on the next oled screen based laptop, revert to white text on black background, so most of your pic will be black.

and that will bring a revolution in screen quality, battery live, and might even help with the non-long live of the screen.

you might have seen some public used led screen (or warning signs). they use leds to create big screens that work even with the sun shining into them, or the sun being directly behind them. they look gorgeous (from far enough that you don't see the individual leds). that's more or less what we'll get with oleds, just in the tiny mini version

 

Quite right! I never thought about that. Thanks for the clarification.

Don't get your e-peen in a twist Trottel. It's okay to be wrong once in awhile.

 

Interesting thread, here at RPI, some of the graduate students I know are making polymer based LED's. I think they are really cool, because they feel like gelatin, and they are soft and flexible. I dont know how great they are colorwise (as in the ability to change color rapidly), but I am sure they will make their way into the LED market eventually.

I dont think I am allowed to post an image or video, since its graduate work

K-TRON

 

AMOLEDS are way better then OLEDS....

 

Never heard of AMOLED

 

Successor to OLED - think there aren't any products using it yet though.

Definitely exists at the development stage.

 

Pretty sure he was just kidding...

 

deleted 10char

 

Now that's flexible Too bad the top isn't transparent

 

So in a nutshell, OLED produces a better picture than IPS, has better response times than TN, and uses less power than any current technology?

 

in a nutshell ... OH YA !!!

plus some of the designs are flexable and extremly durable

your university may have assisted in devolpment but AFIK AMOLED development was a collaborative effort between multiple research centers and companies including Samgung, LG, and Matsuia

 

The concept of OLED basically integrates the LCD (TFT) panel and LED backlight together, and improves on it on almost all aspects (hence it doesn't need a separate backlight). OLED beats LCD panels in terms of response time, color reproduction and viewing angles and beats current LED backlights in terms of power consumption and color reproduction (LED also contributes to color, hence why having the same panel type but w/ LED backlight can be better than w/ CCFL backlight).

 

Ok I was off OLED was developed by Kodak about 25 years ago
AMOLED and Passive OLED interfaces are old as well, just no one took note of the technology much until now

http://www.hdtvsolutions.com/oled_tv_technology.htm
the primary companies on it now are Samsung, Sony and LG

 

no. amoleds use much less power then oleds.

it was developed at my university. and we didn't assisted any company whatsoever. we didn't had help from any research center.the patent is registered by FCT and samsung uses it with an agreement made with FCT. I known what I'm talking about. I worked in the project so just shut up before you make false claims that are false and you can't prove.
and this is part of a bigger project. it's not just related to displays. there are companies using the patent and making for example transparent solar panel windows or a new generation of HUD.
Manufacturing process is still in it's birth but it's way cheaper to produce that's why you are seeing more and more news about amoled.
oled is a completely different thing. and some big companies will just invest in amoled instead of going first to oleds.

the first amoled display was made at FCT in 2006.

 

Could you please give links to support this. All that I have read shows Dupont, LG and the Eastman Kodak Corp having most of the development

and since AMOLED is the Active Matrix variant of OLED technology and 90% of origional patents for OLED is held by the Easman Kodak Comapny starting in 1986. Your university would have had to licence the base OLED technology to develop your own active matrix interface

some of the AMOLED patents

And please dont tell me AMOLED had nothing to do with OLED

AMOLED only refers as to how the display is interfaced and controlled.. an ACTIVE MAXTRIX configuration. We had the BIG active matrix vs. passive displays back in the early 90's.

operating OMLED tech in January 2005 .... you said 2006 it was developed???????

there IS mention of a process for building OLED panels as well as solar panels etc. from your school in works with university of waterloo and many others for solar panels... Amorphous Silicon

http://en.wikipedia.org/wiki/Amorphous_silicon,

but I can find nothing to do with the OLED technology itself or even more specifically AMOLED
