A look back on popular stories from today in a specific year.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
Scientists are fucking awesome...
That's all.
I couldn't agree more :D
My iPhone is better than this.
/being a dick
Im excited for OLED, how long is it supposed to be before it hits the mainstream electronics markets?
Correction: iPhone 3 better have this!
Levi if I were you, I'd put my hopes on iPhone 4 or 5 instead...
I would also read my comment carefully before replying.
Still trying to figure out what the benefits of OLED are, over regular LCDs.
They are fantastically energy efficient, super slim, in theory bendable (yes i want to bend my tv too), and they can achieve true blacks.
If your a TVphile (I am not, still have a widescreen CRT), then this means a lot to you emotionally.
One use for a bendable TV would be in a panoramic widescreen style... like those monitors i remember seeing a while back...
The bendable property could also eventually lead to handheld devices with large, roll out displays.
They're also potentially printable using inkjet or silk screen technology, so there's nothing theoretically stopping you printing off rolls of it to use as magical electronic wallpaper.
They also were supposed to be cheap.
DD,
The advantages mainly come from the fact that each pixel produces its own light. This is very different to LCD displays, where a white backlight is filtered by a coloured panel. The problem with filtering the backlight is that it's very difficult to produce black (you have to block all the light). You end up with the sort of 'light black' that you see if you watch movie credits in a dark room. Since OLED pixels produce the light themselves, they don't need a backlight. Black areas should be completely black.
The other advantage of this is efficiency: when the screen is black, no light is produced and hence not much energy used (when an LCD is black, the backlight is still on and burning energy). I think that OLEDs may be more efficient than LCDs even displaying bright colours (the pixel LEDs are probably more efficient than the powerful backlight bulbs), but i'm not sure.
There are loads of other advantages (mentioned above) to producing light at the pixel site: thinner displays, flexible displays, cheaper manufacturing, and (probably) higher pixel density (= higher resolution for a given panel size).
I hope you were paying attention. There'll be a test next week.
In terms of picture quality:
1) Viewable from any angle (only the most expensive LCD panels can do this.
2) No backlight = no backlight bleed whatsoever. Black pixels are off. In other words, when you watch a movie in wide screen with black bars, the bars will be as black as when the screen is off.
3) Better colors and *much* better contrast ratio because of the black level.
4) Almost 0ms response time; means absolutely no ghosting or blurring ever.
Everything. Seriously they fix every visual issue with LCDs.
Response time: About 100 times faster response than LCD.
Viewing angles: Haven't you notice the picture of LCD changing for the worse if you move off center. OLED will be perfect just like CRT viewing angles.
The biggies everyone will notice.
Pure absolute blacks, and no backlight bleed. And massive contrast because of this, Colors will also look much better emerging from pure black.
Read an LCD forum, you will see people complaining endlessly about poor blacks and backlight bleed...
I have an LCD monitor and LCD TV, the both suck for black.
OLED can't come soon enough.
The best thing about OLED is it being
new technology
yay
yeeh
yay
/sarcasm
Seriously, check out Sony's OLED TV reviews and you'll know whats good about the first mass-produced OLED TV. There will be more good news when OLED TVs are mass-produced by many companies. The only thing I'm worried about is its price. The first TVs will have astronomic prices, IMO.
O! Say, can you see
That's a blue LED...
woops
fuck blue, it looks pretty cool without it

There'd be no white in that picture if blue was absent (in RGB).
And if you were in the CMYK color space, there'd be no green.
You my boy Blue.
Yet another development. Haven't they caught up yet. Its like every month they increase it like this.
That's because it's an emerging technology, and this is what's called research.
aren't OLED TV's supposed to have little to no ghosting and much less input lag then LCD's? if so, I CAN'T WAIT!!!
or you can buy a plasma
If I read the word "gurus" one more time I'm going to kill myself.
I see what you did there.
scientists: thank you for improving my quality of life.
...or at for least improving my TV.
The quality of what you see on TV won't improve, but the picture will look a whole lot better.
...I don't...
"Word on the street has it that PNNL scientists"
What street would that be exactly I wonder, where word of PNNL scientists spreads? ;)
Didnt someone alreadyy improve the Blue in OLED lighting?
Heard of continuous improvement? Pretty much everything you use in your life will of undergone it. Except you.
Anyone know what time "The Four Blue Squares" are on TV tonight?
No, not Blue Man Group...
Efficiency =/ durability. As far as I can tell this "revolution" improves the power EFFICIENCY of the blue OLED, which is great and all, but does nothing to change how long the pixels LAST. Sounds like some researchers puffing themselves up, and engadget took the bait.
SCREW CANCER RESEARCH: Fix that damn, blue OLED problem!
