OLED TV lifespan breakthrough
A joint venture between Toshiba & Panasonic looks promising.
OLED TV lifespan doubled by new build tech
Making better use of emitted light means sets stay on longer
he new breed of OLED televisions are, without a doubt, wondrous to behold, but the use of organic materials that degrade gives them a lifespan that's around 40 per cent less than a standard LCD screen. That, however, is no longer a concern - providing you buy a TV from Toshiba Matsushita Display Technology.
The joint venture between the two electronics heavyweights has come up with a new display that doubles the life of OLED screens by increasing the efficiency of the way they use emitted light.
Efficient emissions
A metal membrane inside the prototype 20.8-inch screen helps deliver light from polymers in the substrate out through the glass surface more efficiently than current OLEDs can manage.
The end result means the brightness can be halved while maintaining the same picture quality, which adds up to doubling the lifespan of screens using the new method.
An OLED TV like Sony's XEL-1 is rated at 30,000 hours - or eight hours a day for ten years - so it's clear that the Toshiba Matsushita approach will eliminate concern for all but the most thrifty of telly addicts.

Re: OLED TV lifespan breakthrough
But even sonys aproach is good enough! 8 hours a day for 10 years! 
With work and all, who can watch TV 8 hours a day?
I could probably get 20 or 30 years out of current OLED TVs.
Just hurry and bring them out already!

Re: OLED TV lifespan breakthrough
It's also possible to use RGBW pixels instead of RGB to reduce energy consumption by half while maintaining the same brightness level.

Whilst intriguing, that approach has no relevance to OLED displays, which have no backlight.

Re: OLED TV lifespan breakthrough
You don't need backlighting, all you need is a simple white OLED sub-pixel.
PS: Samsung already made a ~3" OLED with RGBW pixels for portable devices.
PPS: This method can also be applied to OLED displays that uses all-white OLED with RGB color filter.

Re: OLED TV lifespan breakthrough
Will using a white Oled screen reduce the contrast rating wich is quite amazing with the normal Oled approach?

Re: OLED TV lifespan breakthrough
No, it will maintain the same contrast ratio
In reality, OLED can produce infinite contrast ratio. I guess the one million to one contrast ratio was synthesized just to build marketing hype.
I think this technology will most likely be deployed in portable arena
PS: I make this post on another forum, for those who are interested in this technology

This method is nothing new but, it goes to show how you can improve the image, and save energy at the same time by just adding another sub-pixel (in this case, white).
Here's an example:
By applying this method to current display technologies; you can create an image that is twice as bright with half the power. I’m sure handheld junkies will love this technology.
You can find more info by clicking the links below:
While I am on the subject of display technologies, I stumbled upon a new overdrive technology by CMO who claim it reduces/eliminates motion blur completely on LCD displays without the annoying flicker or the ‘artificial look’ that comes with 100/120Hz processing.
The new overdrive works by slightly dimming the image just before displaying the next. For example, standard Active-Matrix LCDs ‘hold’ each frame for 16.6ms at 60Hz before display the next, which causes retinal persistence. In other words, the image becomes temporarily ‘burned’ in the eye’s retina. If it’s not removed, it will cause blur like effect during motion (when the ghostly image of the previous frame overlaps with the new frame). So by slightly dimming the brightness for the last few milliseconds, the ‘ghostly’ image can be removed or reduced from the eye’s retina.
This idea was actually conceived from the old CRT technology. It’s surprising to see how advanced CRT technology really was (and still is). Below the front glass of the CRT lies the phosphor coating. When it's hit by the electron beam, it becomes ‘excited’ and emits light. The phosphor will continue to emit light for about 1-1.6 milliseconds then begins to fade, which causes slight flicker but at the same time, it helps to remove the previous image from the eye’s retina. Now you know why there’s no motion blur on your old boob tubes LOL.
Make sure to lookout for a LCD displays with this technology in the near future.
