And what have the LCD and plasma? Against the background of these professional monitors, Samsung's color reproduction cannot be called accurate at all)

And I'm not talking about monitors, but talking about flat tv. For home it was better not to find (of course, not for gigantic money). And the CRT monitors are cool, they gave out 1280x1024 while everyone had only 1024x768 LCD

The topic started due to the obvious delusion of some Samsung fans in the great value of AMOLED. They are ready to overpay for such a screen! In general, there are many technology matrices. They can be compared, argued, but the fact that AMOLED is not suitable for professional work that requires accurate color rendition, high brightness and contrast, requires a separate detailed discussion. So that purchasers of smartphones and tablets understand the true state of things, and not be led advertising PR people.
Another major drawback of AMOLED displays is pixel burnout. Yes, it is difficult to notice and after a couple of years on the eye. Exactly as well as on a good plasma TV, some expensive mozdeli which, in my opinion, still surpass in some parameters LCD. But after a couple of years of using the general characteristics of the AMOLED display, due to burnout, the level of the bad IPS matrix will decrease. And in comparison with good IPS, which will be his peers, it will be already obvious to concede.

What other misconceptions? I like this type of screen, I'm ready to overpay for it. Someone overpays for the iPhone. And what kind of "professional work requiring exact color rendition" did you gather on the phone screen? Enough bosh something to write.

You read the first post. "I like". Neither numbers nor objective arguments. And if you had a good IPS matrix with the ability to select the temperature of the tones, as on SGN: “Dynamic, standard, film”, in which you could set the “battered” colors? Those. at will see either emerald grass or natural. Would you also say that AMOLED is better? Assertions like yours are fanatical, based on brainwashing with advertising, and not on objective data. This is the topic behind it.

VitFom,
I have the impression that the topic you "did not read, but you condemn" В©. Once again for those who are in the tank, I have a professional IPS monitor at work, I calibrate it every week. Just "to work with color", oddly enough. And on the phone I like AMOLED.

VitFom @ 01/12/2012, 20:05*

Are you alright? You just can’t get over the simple idea that people don’t like numbers, but that emerald grass is what samsuretion also does.

Well, read what I write - there are no obstacles soft to put emerald grass on IPS. But to make grass natural on AMOLED will not work. From this it follows that despite the “like-dislike” AMOLED has lower characteristics. And some Moskvichi 412 like to drive. Well, the flag in hand, just do not need to say that this is a good car. Say what is good - ghost arguments. The opposite is fanaticism.

Halmburg, on the iPhone 4 costs IPS 960x640 pixels, 326 dpi, contrast ratio of 800: 1. But this is already an outdated matrix - it has more than a year of sales. New superior in performance.
nif-nif, read the first post and do not forget that everything is conditional. Someone walks with glasses, lenses and all one does not notice any difference. But here we are not talking about them, but about the technical characteristics of AMOLED and IPS. The accuracy of color transmission is measured by the level of coverage of the RGB spectrum, and not "like-dislike".

And the graphics of gamma curves and color coverage for some IPS display can be seen here? Without them, all disputes can be considered petty and groundless. Oh, they really show the real possibilities of the screens.
For example, here it is for Galaxy Note (SuperAMOLED HD with the screen settings on the standard):

No, I did not find any graphs on RGB, but I advise you to look at other characteristics in the Display section of the following tablets with IPS
http://www.notebookcheck-ru.com/Obzor-plan...-S.65552.0.html
http://www.notebookcheck-ru.com/Obzor-plan...ad.60193.0.html
http://www.notebookcheck-ru.com/Obzor-plan...1v.59574.0.html
http://www.notebookcheck-ru.com/Obzor-plan...K1.64598.0.html

But IPS with sRGB coverage charts, but on an old Windows7 tablet Asus Eee Slate EP121:
http://www.notebookcheck-ru.com/Obzor-plan...21.50908.0.html

The problem is the absence of the same full-fledged test programs for analyzing the range of color coverage on Android and Windows. If you can understand something, then compare your graph with the graph of Asus Eee Slate EP121, but it is far from the best IPS display.

VitFom,programs for analyzing the spectrum for android and not found, because all the data obtained from the measuring device directly to the computer.
But from your link I remembered one of the advantages of amoled - they generally have no such thing as uneven backlighting

nif-nif, well, let's try to figure out the link in your graphics. I post it a screenshot. The caption below suggests what's what: "IPS LCD, Super AMOLED, AMOLED, and TFT, represented by iPhone 4 and Droid, Galaxy S, Nexus One and iPhone 3GS, respectively." The black-triangle smith is the natural gamma. It fits IPS on the iPhone and Droid. But everything else is distorted and zadrano in different directions. Yes, bright, yes, the grass is emerald, but this is not at all good, as some try to expose. I would not want to have a TV, laptop, monitor with Super AMOLED. Since sometimes I look and process the photo. Besides the fact that I appreciate the natural colors, the photo must be calibrated in color correctly. Otherwise, on a quality IPS monitor or TV, it will look like it was photographed or edited, if it is RAW, and emerald grass appears on the "harsh" monitors. And it will definitely appear exactly the same on Super AMOLED and AMOLED. Pay attention, their gamma completely coincides and it departs naturally (black triangle) significantly. I actually stated this. And from the graph it is interesting that the most natural color gives Droid (IPS, judging by the explanation). But what is this Droid? I know of 4 Motorola DROID models.

Valo-lo-lo, I agree, IPS has such a flaw, but on high-quality monitors it is invisible to the naked eye, unlike emerald grass.

waaake, very sensible article. In the section "Brightness and naturalness of color transfer" you can immediately see why AMOLEDs are the worst. It is enough just to compare the color scheme with IPS with your own eyes. Then look at the "Photometer reading" and no longer say that AMOLEDs are able to compete with IPS in brightness - not less than one and a half times worse.

Well, so that fans of AMOLED would not be sad, I will inform you that in Japan they are going to release a display on liquid crystals, a new generation that will be able to argue with IPShttp://www.mobile-review.com/articles/2012...2-fujitsu.shtml. But we don’t buy Fujitsu ...

Judging by the other phones - the first ^ _ ^ I mean the same Milestone ^ ____ ^ i'm happy
But why they have not compared yet with Desire?
At iPhone, my heart feels, the screen is so specially tuned by Apple, for some reason

Suddenly! By colors Meizu M9 wines, second Atrix, third iPhone
(I speak as the owner of almost perfect distinguishability of gradations of colors, passed an interesting test here =)
But damn PenTile spoils the rest of the raspberry motor
In Meizu raspberries spoil the viewing angles and brightness
In the iPhone, raspberries spoil not the best features everywhere, the eternal "second"
Think here
