Breakthrough could lead to 400% clearer smartphone displays

Breakthrough could lead to 400% clearer smartphone displays
Using nanotechnology, Professor Stephen Chou increased the effectiveness of solar cells by 175% back in 2012. Now, Professor Chou has improved the LED. Besides making them last longer and more efficient, the professor has made LEDs five times clearer. The implication for smartphone users is tremendous. Currently, only 2% to 4% of the light generated by an LED is actually emitted by the diode. This makes the light dim and also helps give an LED short life since it is generating heat inside itself.

Scientists have been able to raise the percentage of light generated by LEDs to 38%. In doing so, it creates ambient light which causes the image to become hazy. But Chou has been able to eliminate the ambient light with a nanotechnology structure called "plasmonic cavity with subwavelength hole-array". Surely you remember that from science class, right? This raises the percentage of emitted light to 60%. Contrast is increased by 400% and the whole process rids the LED of the heat that costs it long life.

Testing still continues, patents need to be filed, and there is still a long way to go before this comes out of the lab and into your smartphone screen. But the technology does exist to improve the displays on future handsets. It is all just a matter of time.

Will let that sink in for some time.

You know what I love? That your sour grapes can't be masked by fake laughter. Your beloved Android is bankrupting companies (Well, the ones Apple isn't chasing out of the game), and by this time next year, the Chinese OEMs will probably finish the rest. Still funny?

High brightness and the battery drain of the lowest setting? bring it on!

One thing that isn't clear to me in this article is, will this technology improve both LCD and OLED or OLED only? (Considering most LCDs nowadays are LED backlit)

It will improve both, OLED will have bigger benefits as LCD-LED is just LED backlight.

The 2012 phone screen on the iphone 6 has made it clear apple has no intention of going above the "perfect" ppi. If they did their battery life would be horrible anyway.

Would this be great news for TV's as well or is higher contrast not really an issue for larger than phone LEDs?

High contrast is an issue for LCD-LED TVs, only OLED and Plasma have high contrast.

This could make the perfect AMOLED display and eliminate all of the issues that have plagued it...

I guess the next decade will torment us with the marketing terms "nano" and "quantum".

Samsung will start a mobile display monopoly with this

Flexible Amoled that uses 10% of the energy of whats in the Note 4 right now with natural improvements over the years doesn't sound bad at all...

Now this sounds like a patent worthy idea.

People will just claim it has unatural colours because it's not the type of LCD they are used to seeing.

The thing with natural colors is they don't look very appealing to the majority of people, most people prefer slight saturation as it gives the color pop that stands out.

Not if apple uses It seems any tech apple use is perfect for the media. When apple adopts AMOLED tech you can bet the media will change their tones. The only reason they hate AMOLED is because it's associated with samsung. Why make the foreigner look supreme???

Iam sure galaxy 6 will have this.

They should implement it soon. Not even the ultra fast less than a minute battery charger has been released yet.
