Im excited for OLED, how long is it supposed to be before it hits the mainstream electronics markets?]]>Mar 23rd 2009 4:18AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/Mar 23rd 2009 9:33AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/Mar 23rd 2009 2:00PMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/Mar 23rd 2009 2:12PMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/Mar 23rd 2009 4:22AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/
If your a TVphile (I am not, still have a widescreen CRT), then this means a lot to you emotionally.]]>Mar 23rd 2009 4:24AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/Mar 23rd 2009 4:25AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/Mar 23rd 2009 4:37AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/Mar 23rd 2009 4:43AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/Mar 23rd 2009 5:11AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/
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.]]>Mar 23rd 2009 6:07AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/1) 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.]]>Mar 23rd 2009 4:18PMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/
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.]]>Mar 23rd 2009 8:28AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/
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.]]>Mar 23rd 2009 2:04PMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/That's a blue LED...]]>Mar 23rd 2009 4:22AMhttp://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/http://www.engadget.com/2009/03/23/scientists-purportedly-improve-blue-oled-efficiency-by-25/fuck blue, it looks pretty cool without it
