Smartphone and tablet displays expected to improve hugely in 2014 with 'Quantum Dot' LCD tech

Smartphone and tablet displays expected to improve hugely in 2014 with 'Quantum Dot' LCD tech
2014 is expected to bring us not only higher-resolution displays like the Quad HD 2560 x 1440-pixel screen rumored to come with phones like the Samsung Galaxy S5, but also dramatically improved colors. The culprit? A nascent ‘quantum dots’ LCD technology that we first saw in the Amazon Kindle Fire HDX 7-inch tablet last year. While the technology appeared on just one tablet last year, quantum dot displays are expected to become much more common in 2014, bringing a much needed improvement in smartphones and tablets, according to DisplayMate screen expert Raymond Soneira.

The problem with current LCD technology is that it uses white LED’s with yellow phosphorus that produce broad light spectrum, which makes it hard to achieve nicely saturated colors. Quantum dots, in contrast, are capable of converting light from blue LEDs directly to produce highly saturated colors, similar to the ones in AMOLED displays. Even better, quantum dots allow precise tuning and calibration during the manufacturing process, which should increase the color accuracy.

The staggering difference can be best seen in a spectrum chart comparing a traditional LCD display (used in the iPad mini) to a ‘quantum dot’ one (used in the Amazon Kindle Fire HDX 7).

Notice the advantage of the quantum dot LCD display of the Kindle over the iPad mini

The new technology would also be instrumental in overcoming the narrow color gamut of devices like the iPad mini with Retina and the Microsoft Surface 2.

All in all, we can expect to see not just sharper screens on mobile devices in 2014, but more accurate and colorful ones. What’s not to love about this? Feel free to also check out the slideshow right below showing other upcoming technologies that will improve our mobile screens soon.

Great, combine all these techs together makes amazing display.

The displays need improvement on the colors reproduction, the resolutions are already good.

I think the most important part of displays that need to be improved is their battery consumption. Right now, displays are pretty damn accurate and more accuracy, while welcomed, either won't be used by most manufacturers or will not be very noticeable to many people .

Couldn't agree more! And they actually are hugely improving - the displays of devices like the Surface 2 are incredibly power efficient in comparison to say even the IGZO iPad.

Get it right. The igzo iPad display is more power efficient then the surface 2 tft display. In fact the iPad air display is 52% more efficient compared to last years iPad display.

Facts beg to disagree.
The iPad Air display consumes around 4.8 watts at 450 nits normalized for 9.7 inches, while tablets like the Kindle Fire HDX 8.9 only uses 3.7 watts. The Surface 2 is even lower.

I think there's a bigger problem for battery life on mobile devices: the cellular connection which consumes way more power than display panels. you could turn the brightness down to 10% and perform tasks like instant messaging or file syncing continuously, and still see the battery getting reduced by 20~25% an hour on, say, an iphone. the cellular connections are beasts :(

Another thing they should try improve are the refresh rates, I think they're currently 60 Hz, would nice to get 120 Hz or 144 Hz.

Looking forward to the S5 announcement and how well they made that QHD screen!

The S5 might well have an AMOLED screen, not LCD, but we're all curious!

Victor... how is this tech different to Triluminous from Sony? really curious

Trilum. is garbage while this is better in every aspect.

well my question was about the technology used... if its the same approach, and if the quantum dots are used in a similar fashion...

I really wasn't looking for your personal opinion this time.

BTW, the TRILUMINOUS screen of the Z1 Compact is actually very good...

The one on the Z1 was disappointing because it didn't use IPS and probably a different calibration... but the one on the Compact is actually better than the one on the iPhone 5s in most aspects

From what I think it's.. It's not a technology, it's a slightly wider color gamut from sRGB.

It's not different. Actually, 'quantum dots' is the generic name for the technology, and Triluminos is the marketing name for one particular implementation of quantum dots.
It used to be too expensive to produce, but now it's coming to life, and we hope to see it in more devices in 2014.

As soon as I read the article, my immediate question was how is this different from triluminous Tech..Was scrolling down to see some one asking the same question and u did..:)

AMOLED QHD would be a dream come true.

The word culprit is incorrectly used in the first paragraph, third line.

On topic though, this is great news although I bet most manufacturers (except Apple and Google) will just try to oversaturate their displays.

AMOLED (OLED) technology is already reaching perfection..

Disagree!

Interesting why in this article aouthor didn't mention anything about two biggest OLED problems: Short life span and Burn-In effect...

it's ok for amoled to go for a 2K resolution because it's not really 2k in the first place. remember pentile/diamond pixel arrangements? however, lcds should just stick with 1080p. they'll probably be sharper even when compared to a 2k amoled from samsung.

You pretend to know what you are talking about but the PenTile matrix has 33 percent less pixels.
Do the math.

People need to make up their minds. Either pixel densities above 300 aren't perceptible or they are. But, check the displaymate reviews of the S4 screen. Diamond doesn't hurt it in any way.

Why improve colors when most OEMs go out of their way to over saturate all colors already.

How do these displays compare with amoleds in the blackness department? When I need to up the brightness in videos, I hate how everything becomes washed out and grey on my LCD screen tablet. Will these new screen techs improve that and be comparable to amoleds in that area?

There's no need for displays to go above 400 PPI. I think companies should not make phones any higher resolution because it doesn't really make a difference beyond 400 PPI...
