I've been reading alot on the new display techonology called OLED. It has some nice advantages:
-its cheap to produce
-alot of companies are getting behind this technology, and this could help alleviate the problem of the LCD shortage the technology industry is currently experiencing
-it uses far less power than the typical LCD screen, which needs to power both the screen and the backlight in order for the screen to be visible. OLED screens illuminate themselves and are resultingly much more power efficient (this will extend the short battery life of the PSP)
-because it doesn't require the use of a backlight, its a much thinner display than the new LCD screens you get with computers now. the displays are so thin that many are being manufactured in full working form on materials that resemble a thicker paper.

After reading all this and understanding Sony isn't completely financially retarded, I strongly believe they will end up putting this technology in future PSPs. And since it will extend the battery life significantly, maybe we should wait.

I think this tech will be in PSP since day one when it launches, I mean consider how much money theyll save and according to this dude I know theres an LCD shortage, he knows that kind of shit too so I took his word.

Sony have been some of the biggest contributors to OLED for years, theyr the core of OLED research.

This stuff is incredible, it uses the same amount of electricity as an LED, man can you imagine what this would do to the PSP's batterylife?

The PSP has a 10 hour battery life, the screen probably consumes about 90% of that battery, with that 90 percent virtually gone it could give the PSP like a 90 hour battery life(considering the Sony walkmans which play CD's and dont have screens but plenty of LED's max out at 90 hours).

OLED technology is incredible and it would PSP at a level if it was incorporated, the damn thing is as thick as paper too and has no film so they could make it tiny.

I think Sony will try to incorporate this into the PSP at launch but if they cant then theyll do it at a later date, I cant wait to see this in the PSP though, the thing will shrink even smaller than it is now the resolution can upto quadruple a similiar sized LCD.

so OLED is cheaper to create ?
if so.. soney would be stupid if they didn't use it.. :D

Yeah thats what im thinking, why wouldnt they want to use it.

It should be ready by now theye ben working on it since 1999.

Hmm... I remember reading about OLEDs a few months ago, in a magazine. Organic um.. light emitting diodes or some crap like that. Didn't read about them being cheaper, but cheaper is good.

LOL, its like a paper thin piece of plastic that lights up when current flows behind it, its incredible :shock:

Anyone actually read that the problem with OLED that manufacturers are having difficulty trying to fix is it's shelf life? The organic material wastes away with time and can also suffer from screen burn quite badly, with blue being the first colour to go.

I've read about worst case scenarios of 2-3 years 'light' use before screen quality has noticably decayed to about half the brightness. If you'll be playing a PSP every other day then I'de say about a year if you're lucky. I think manufacturers are giving display guarantees in *months* right now.

And LCD production lines are what, about 3rd / 4th generation now? I think we've a good few years wait before OLED gets to the state LCD is in right now. But the quality of OLED right now does supercede LCD loads - it just don't last...

They actually dealt with that, all they did was put a screen behind the OLED which seperates the current and the screen, what wsa basically happening was when you ran it for a long time the screen used to get hit by increasing heat from the current and the screen started melting.

All they did was increase the distance and put a filter between the two.

The problem they were having was making it bigger than 5 inches but they have a 51inch OLED available now.

Yeah unfortunately the blue aspect of the red, green, and blue layers needed for OLED is still a problem. This is why I don't expect OLED to be with PSP at launch.

I haven't read any problems whatsoever on image burn-in, but I have heard the blue layer only lasts something like 3k hours while the red and green layers are up at 15-20k hours. Still, these are nowhere near the 40k-60k hour life of LCD screens.

Sony has stated they want the PSP to have a 10 year shelf life, so:
10 years X 365 days = 3650 days
3650 days X 5 hours/day = 18250 hours

So if you played your PSP for 5 hours everyday for 10 years (ha...yes this is overprojected, but better to over-estimate than under-estimate) the PSP OLED would need roughly 20k hours of life.

Here's a link to an article at PC Magazine summarizing the advantages/disadvantages/differences between a plethora of display devices including OLED, LCD, DLP, and LCOS.

You can buy a PSP from:

and It'll be Jap or wait a few more months and get it over here.
But I really wanna get one straight away. But the only thing is. I don't wan't to buy one and when I play a European game on it. It dosen't work cause my PSP's Japaneese

They wont use OLED because you gat distortion when the screen is over about 2.5 inch somthing that may be used in the PSP2.

I agree they want the screen to be as good as it can be so they will wait until OLEDs have inproved.

Yes they will wait until it has been inproved and it can be made bigger with no distortion so they will want at least a 5 inch with no distortion to make a 3 inch.

I couldnt find the other articles, this one will do though, theyve made screens bigger than 5 inchs now and theyve got better resolution and picture too...


Seiko Epson announced on Tuesday the development of a 40-inch full-color organic light-emitting diode display.

This is the largest such display in the world, said the company, which expects to commercialize the technology by 2007.

Using organic light-emitting diode display (OLED), Seiko Epson aims to capture the market for mid-size televisions smaller than 40-inches, said Seiji Hanaoka, vice president and CTO of Seiko Epson.





The company, better known for its printers, said it had developed an inkjet process for depositing organic layers on large-size TFT substrates.

"We have our roots in the PC field, so we are not going to directly compete with consumer electronics companies (that have) lots of audio/visual expertise," said Hanaoka. "Instead, we hope to make inroads into the TV market with such original approaches."

OLED displays use an organic material that glows when an electrical charge is applied. This light-emitting characteristic means that devices need less power to run and can be thinner than LCDs, which are dependent on a backlight.

The technology is already being used in products like digital cameras and cell phones. However, these displays have so far been limited in size, such as the 2.2-inch display on the Kodak EasyShare LS633 camera.

When asked about the prices of OLED-based TVs, Seiichi Iino, Seiko Epson's director in charge of developing OLED technology, said he expects OLED to be able to compete with LCDs as the cost to produce the basic elements of OLEDs is comparable to that of LCDs. OLEDs do not require components such as backlights and film, he added.

Since going public last June, Epson has been aggressively expanding its product lines into newer fields, especially large-screen TVs. In February, the company launched its Livingstation LCD rear-projection TV line in the North American market. This wide-screen, high-definition TV comes with a built-in printer and CD-R drive for printing and storing images.

they already use OLEDs, in Mobile phones, take a look at the Samsung E700 or the LG 7100, they both have OLED outer screens & they aint good enough for the PSP...

Those are just paper thin screens put over a normal LCD screen to increase the resolution, this is a whole new league.
