World's first quantum dot monitor

[jos]

Philips claims that its 27inch Full HD 276E6ADS monitor, above, is the world's first to use QDs. It has worked alongside specialist firm QD Vision to incorporate Color IQ technology into the monitor.

 

"Quantum dot technology is changing the way monitor users think about colour, and the new 27-inch E Line monitor is the first on the market to showcase this new technology," said Stefan Sommer, Director Marketing & Business Management EMEA at MMD. Sommer claims that the new monitor can display 99% Adobe RGB colour "at a very aggressive price point". This is in contrast to most monitors on the market today which can only present roughly 70% of the full Adobe RGB standard, according to Philips.

Quantum Dot

The newest type of LCD backlight is called "Quantum Dot Enhanced Film" (QDEF), though it is more commonly referred to as QD or QD-LCD. Quantum Dot Enhanced Film backlights are based on an LED backlight with an additional layer (the quantum dot film) which allows them to be substantially more power efficient than traditional LED implementations. In addition to better efficiency, quantum dot backlights provide a very wide color gamut similar to OLED, enough to easily cover the entire sRGB color space (standard gamut) and even the entire AdobeRGB color space, a feature usually reserved for graphic design and photography specialist monitors. This market is where Quantum Dot backlights will be most useful, since a wide color gamut is a bad thing for standard consumer content. Most types of content will appear grossly oversaturated on a wide-gamut display, already a common complaint with OLED displays on phones and TVs. Only specialized software with built-in color management capabilities to compensate for the wide color gamut will appear as intended, such as Adobe Photoshop, when properly configured.

 

 

What's "Quantum" about them? Is that just completely meaningless marketing nonsense?

 

No, actually. Quantum dots were not invented or even named by the TV industry. They are a (nano-)crystalline structure discovered by physicists in the 1980's and named by a researcher at Texas Instruments at the time. They are basically atomic-scale structures which absorb light of one color and emit the energy as light of a different color. The emission color depends on the size of the structure, which can be finely tuned during manufacturing. They are called quantum dots because their basic operation is dependent on principles of quantum physics, where energy is released in discrete levels (quantized, as opposed to continuous) giving it a very tight, consistent band of color output instead of a continuous spectrum.

 

Current implementations of QDEF backlights use blue LEDs in combination with a film of red and green quantum dots which will convert some of that blue light to form a balanced RGB output.

 

 

What is the advantage of a Quantum Dot backlight over other wide-gamut technologies like RGB-LED backlights or OLED?

 

Aside from power efficiency, where QDEF handily beats both RGB-LED and OLED except on very dark scenes, Quantum Dot backlights are better in the long term for artists and graphics professionals due to their excellent color stability. As explained above, RGB-LED backlights drop in color accuracy over time since the different color LEDs degrade at different rates, hence requiring periodic re-calibration. OLEDs degrade in brightness as well, and since each sub-pixel is an individual light source, they all degrade by different amounts depending on how much that individual pixel has been used, leading to color balance issues which are different for every pixel. This means that OLED displays not only lose color accuracy over time, but they lose it permanently. They cannot be re-calibrated by normal methods since different sections of the display would require different calibrations.

 

Quantum Dots, however, do not degrade with usage. The blue LEDs which provide the light will slowly degrade, but since the LEDs are all the same color and all operate as a unit, with the same brightness and same activity, they will all degrade uniformly. Since the Quantum Dots output light based on how much they absorb from the LED light source, when the blue LEDs drop in brightness the red and green output will drop proportionally as well, which means the only effect is that the display gets slightly dimmer over the years, which isn't a problem since most displays have adjustable brightness and most people don't run it at 100% out of the box.

More excited for OLED personally, since I dont do any professional color work or anything that would benefit from QD panels

[EliasNM]

A contender for IPS panels. I would like to see the price tag as well, I am expecting a 1K range price tag.

[BigDay]

make it 1 ms with 144 hertz plz

Quantum Dot is a type of backlight, it doesn't compete with IPS, it's used in conjuction with it (or some other type of panel).

I referring more to old vs new, nothing more, should of being more detailed. Only I knew what I was saying.

After hearing about quantum dot for so long, its nice to see it in monitor production.

Oh, sorry then though I still don't get what you were trying to say

I was referring to E-IPS , e-IPS and S-IPS panels I'm probably forgetting one more, there are the different IPS panels over time. The correct term I should of used the first time should of been among not for, but whatever.

[TroubleKlef]

I would love getting a cheap QD LCD until OLED comes down in price.

[JAKEBAB]

 

So what is the better tech, OLED or LCD with Quantum dot? as i was under the impression OLED is the be all and end all of display tech but with what u have just said, it makes me question it

Correct me if im wrong but they are all just variations of panel tech not back light like quantum dot.

OLED has more potential, but is not ready yet. As soon as the longevity problems are addressed it will be better than LCD in every way.

Haha. Well played. Also shame on anyone who doesn't know of Pure Pwnage >_> it was the shit back in 2004-2007 if you were a PC gamer.

Quantum Dot is a type of backlight, it doesn't compete with IPS, it's used in conjuction with it (or some other type of panel).

I think you mean: Quantum dots + LED, and not just quantum dots. They don't produce light from my understanding, they switch light color, as you explained yourself.

Also, you don't need "specialized software" for color profiles. My desktop monitor is a wide gamut, Adobe RGB calibrated.

1- The saturation is more like 5-8% over what it is supposed to be. And not a deal breaker for non-graphical artists. If anything, it makes games sun, lasers, and what not more vivid as they should be.

2- Windows photo gallery and photo viewer supports color profiles. Windows will automatically get the color profile of your monitor via Windows Update, and set it that. You can also change it to sRGB color profile, if you prefer that one, and that one is built-in Windows. But it is best to use the monitor color profile, actually that is a lie, for professional work, you want to use a profile generated by your color calibrator, but not everyone has one.

3- The only configuration you need to do in PhotoShop to work with wide color gamut or sRGB color space is set which one you work on, based on what you want to work on.

The reality of things is that sRGB is very restrictive in color spectrum and doesn't represent 'real life'. Wide gamut represents a better 'real life' color set. The only reason why sRGB became standard, is that people bought budget class CFL backlit LCD screen, and now they are buying white LED backlit screen, instead of wide gamut versions, making it the standard instead. That is why content on wide gamut monitor appears a bit more saturated. It is because most people are on sRGB (well, not even close to sRGB), because they don't want to spend the extra bucks.

What about blacks? I't kind of annoying to see only the strong backlight level and no details in darker scenes.

Blacks should be more or less the same, as you still have a back light, which is a problem for LCD technology. It really comes down to the panel technology in being good at blocking light. The real solution is returning back to CRT days TV/monitors, or go forward with OLED. CRT it is a light cannon that draws the screen, and OLED produces its own light, so OLED will be as black as the background the TV or monitor has, which isn't hard to do in order to get really good blacks.

Technically yes, though the graphic was intended to be for the "layman", to correct people comparing "LCD vs LED" or "LED vs IPS" etc, Quantum Dot is the term used commonly, so that is what I put I mean, I could have also branched out the LED into some WLED/RGBLED sub-bullets, but don't want to overcomplicate it.

Yes, my wording is perhaps a bit strong. The point really is that I don't want people getting excited over "wide-gamut" without really knowing what it is. And it's not only on Windows, it's very likely to become a thing on phones too, QDEF is very scalable to small sizes unlike RGBLED, and of course as phones are such a big market and I think they will be running out of things to do with the resolution shortly. As we have already seen with Samsung phones the complaints about oversaturated OLED screens are very commonly recognized, because Samsung didn't bother to correct for the wide gamut. I think their newer phones now have color profiles you can set in the options (in response to the complaints) but their earlier phones didn't. Basically the point is that wide gamut won't look automatically better to the standard consumer, the saturation will most likely make everything look "off" out of the box. Whether that's because it's actually oversaturated or because sRGB is just undersaturated and they're used to it, is a bit beside the point. While it is possible to set up a wide gamut monitor properly to use for everyday usage without everything looking funny, IMO I would only recommend them to people who know what they're dealing with.

[GoodBytes]

Ah ok. I get you.

But I don't want people to have in mind that wide gamut is bad and avoids it like the plague.

It is definitively the way forward, and I think having most phones with wide gamut display will take the PC space as well.
