What kind of impact could this have for computer displays?

 

[taltamir]

this is merely step number 72 in the long but inevitable process via which OLEDs come to dominate the display market.
Hint: I made up the number 72

OLEDs will take over in no time once a manufacturing method that can get them large is hammered out. Within a few years in the TV market.

I'd imagine that they will replace LCDs in phones entirely by 2012.

The only limiting factor right now is R and D recouping and currently large capitol for the printers, the raw materials cost almost nothing. They are literally manufactured with something akin to an ink jet style printer. Not to belittle the exceptional engineering that has gone into the design of the manufacturing, it is very tricky still for long lasting large sheets... But they are very close to being the most inexpensive display technology we have ever had by a long shot.

I can't imagine it will be long before we are totally sick of them as they start to appear pointlessly in everything like LEDs did 15-25 years ago. "Not selling enough shoes, put a light/clock/tv in it".

Yep.

Here was a 2009 release from Dupont on the matter of durability. (I got the link from the initial May 2010 link I provided).

Besides cost, what other specifications should we be aware of? How about Viewing angles? I do know the OLED viewing surface can be arranged in a curve due to the flexibility of the printed surfaces, but what about Large flat OLED surfaces? How would a large high resolution sheet compare to IPS or TN?

 

[taltamir]

OLED have a 180 degree viewing angle... 360 for see through OLEDs.
Viewing angle is an issue in LCDs because they polarize the light, in OLED each cell (pixel) is a translucent light source and as such emits light in all directions equally. Also OLED have CRT like response time (which completely eliminates ghosting)

 

[Sylvanas]

Yep, we've all been watching the small steps of OLED for years now hailing the end of LCD's and a new King to be crowned but really, it needs to f'in get here already! You can buy small OLED displays, I think Sharp had like a 14" screen that was a few thousand $$...it's here, it just needs to be affordable.

Response time for OLED are the absolute best, it would be able to show over 120 fps...

But the best part of the OLED promise is how it's flexible.. Imagine outfitting a "gaming room" where the walls, floor and roof are entirely made of 3d oled

there are a lot of bests about it... you can make an transperant oled cube that shows real 3d (now THAT would be expensive )
you can print it with a modified inkjet printer, so eventually it will be super cheap.
it has awesome response time so no ghosting
it has perfect viewing angle
it has perfectly dark darks
it has very low power consumption (a fraction of an LCDs)
current displays are already less than 1mm thick. (I think I recall some being 0.2mm) so its super light and small.
etc etc... this is an amazing tech. every day it gets cheaper, better, bigger...

Apparently OLED can even be rolled up.

Sony says it will continue to improve the performance and reliability of its flexible organic displays as it expects the technology to yield thin, light-weight, durable and mobile devices with previously unachievable form factors.

How about resolution/pixel size?

I noticed triple layer OLED is capable of 3 times the resolution of single layer OLED due to the blue, green and red being at different levels. However, I haven't seen much in the way of single layer OLED vs LCD comparison?

If we see an increase in the resolution standard (among other things) what implications will this bring to both GPU and GPGPU? Nvidia CUDA and/or OPEN CL programming?

it doesn't really work that way... if you have a 1920x1200 resolution blue layer, green layer, and red layer:
1. they need to match up for good quality.
2. they cannot be intentionally mismatched for a higher "effective" resolution
3. the total effective resolution is 1920x1200

I think he meant that in a LCD x1200 display, the RGD diodes are beside each others, so let say each is 1mm arranged in a line, you get 3mm for the pixel. Imagine the same size for an organic diode, but stacking them, you get the full pixel at 1mm size instead of three, effectively allowing 3 times more pixels on the same surface, thus tripling the maximum resolution. This, of course, assume that organic and standard diode are the same size, something I have no clue about.

you can make them different sizes... you could also make them "side by side" or one on top of another.
In the google nexus 1 for example the OLED cells are side by side and are non uniform in size (each cell is 2/3 green, and 1/3 either red or blue, alternating red and blue cells)
So its "effective resolution" is actually a lot less then what they advertise.

Here is where I found one reference to the "tripling of resolution" effect for stacked OLED. They compared to LCD in this case.

 

[taltamir]

its a wiki, it says that stacked oled does triple, it has no source backing up that claim.
