In the IPS and 60 pixels per second switching not time.

Eem, did 50 switches can be under 20ms

Blah, it's just PPC. Frequency sweep-term technology from CRT
What kind of shit you have in mind electron beam is controlled by magnets, ran in rows and reverses the image.

You do it, humor, well, do not you understand? And you also have sort of downtrodden ignored.I mean, even in different themes people behave differently, but in one

The size and cost. You really think that the quality displeychike size of 4 inches, and cost less than $ 100 will be the same as a large monitor worth 1000?

Lord, to intervene in the "meat grinder" with the issue. Is the new Taba will burn out pixels in 1-2 years? I do not gig, and the desire to change the gadget through a year or two I have.

P.S. I'm thinking about buying a tablet with 7.7 -tab SAMOLED plus or wait for ASUS Memo with IPS.
transmitting the truth of colors not particularly worried, but the life of the screen, yes. On the day of the screen will be used ~ 6 hours (mainly in komandirovkah- read books and films, in addition to calls and neta).

Sincerely.

2 years- it at 12 hours. In general, the pixels in two yearswill start burn. You simply do not notice at first. all 4 years it is released when your mode.

It says that the OLED display are less durable. But business will last enough, otherwise they would not have released.

Here was a heated debate about the gamut (CO). I always thought that if the CO real screen smaller than the standard triangle in any part of the (Apple Iphone), then the colors he reproduce simply can not, and if the real scope of the triangle is completely absorbed standard and made for him (Gugle Nexus One) some colors are obtained oversaturated, which, however, is easily amenable to calibration.
Maybe I misunderstand? Correct, if that.

In general terms, this is the case.
Little add, black triangle (sRGB) standard only in the sense that it is one of the standards, the most basic and shabby (and not the mythical "reference range": D), and only the image will be properly reproduced, obtained with the use of this standard. Here is a small example of sRGB and AdobeRGB differences, and what happens when you try to play on the device sRGB file with a much greater COhttp://www.dpreview.com/reviews/nikond1h/page17.asp(Section colorspace).

I can finally lay not idle talk, and additional tests AMOLEDhttp://www.notebookcheck.net/Review-Samsun...ID.68814.0.htmlLook. Contrast is really very high, because Black 0.01 cd / mВі. As a result, 32,800: 1 - very good. Brightness on the average of 344.3 cd / m - less than good IPS, but also good. Note In all better than the vaunted SGS2 with Super AMOLED +. In SGS2 pixel density of 217, and in Note 285 pixels per inch. Good display. But the brightness does not reach the IPS. Not bad, not much inferior IPS, and transmits color.
Part colors. Well do not want to believe the tests for 2 p., Where clearly visible in the pictures color distortion that any software or settings are not correct. Take SGS2, as already advised in the store, and take a picture of an object near the bright blue, green or red. Bring to SGS2 subject to the photo on the screen. Color is so obviously at odds with the original, you have to be color-blind to not notice. In the Note, by the way, a little bit better with flowers than SGS2. Samsung can realize the mistake and did not "lift up" on it so the colors?

NIF-NIF, your knowledge of technology wants to be better ... Scan is on all LCD. On my home 3D LED TV - 200Hz. A Note on she 58Hz. Even a little lower than in the conventional IPS.

Sumashedshii, You are confusing dynamic contrast with the usual. Dynamic, as already stated above, is easily measured by the millions. For example, my LCD TV produces 8 million: 1. And it's not much. When I am buying, compared with models with 10,000,000: 1. This gives now the LCD TV without any organic crystals. But these millions - dynamic contrast.

Anything I do not confuse. My methods are just a standard contrast. Dinamicheskaya- when it measures the first white image, then black, but when displaying black color is muted lights on the display, and black is black. In life, the dynamic contrast ratio is practically not working.
And yes, in view of the fact that the lights on the AMOLED not as a class, on it there can be no dynamic contrast.

Compare the color in the real world with the colors in the pictures made far SLR is certainly strong. Also in that article as a test pattern used a picture with four squares, but it will look almost the same on all phones, not like there.

GamutRGB. Yes. The problem is how to display it ... It's necessary to copy all the OS under it to start ...

Tell me ... what good is a wide coverage GAMUT AMOLEDom when images ANDROID findings in 24-bit color?



Rep: (88)
Sumashedshii, you are very similar in logic to the NIF-NIF, which the LCD is not scanning. Dynamic contrast ratio is not related to modern technologies for disabling panel LCD LED entirely in black, which is no different from nesvecheniya crystals in AMOLED. Bit lekbeza:
"Dynamic contrast ratio is the number of bright white dots in the scene or image in comparison with the dark black. When a dark image is displayed on the screen, the backlight shine weaker. This improves the transfer of dark areas in the LCD panel. Brightness is measured in candelas per square meter (cd / m2). Thus, the larger the value, the brighter the image on the screen. "
And now there is the studied contrast:
"Display Characteristics, which is defined as the ratio of the luminance of the brightest color, that is white, to the darkest color that is black that the display can display is called contrast ratio. This definition applies to all displays, whether the LCD screen or CRT picture tube. " -http://myhdplayer.ru/chto-takoe-dinamiches...ntrastnost.html

Thus AMOLED has a scan, and both types of contrast.

In addition, I understand perfectly that there Pentile in Super Amoled. But I would ask my groundless aponenta look again in tests on the 2nd page. Bah! A gamut of already perezhovannym triangles sSGB matches in Super Amoled Plus and Super Amoled. And then are already marketing the chips. On SGS2 distorted, with his color, like in SGS1, and in Note no, but it is also to IPS in the iPad2 does not hold. And do not be idle talk - you want to prove Amoled advantages bring graphics tests, numbers. Incidentally, the mere assertion of the superiority of some PR Contrast thousands of times already can be attributed either to stupidity or to the advertising relationship.



Rep: (161)
If anyone make Adreno and PowerVR or Mali or show Tegra Android system in AdobeRGB, or at least to reach AMOLED RGB - a monument put. Until then - all this coverage is not needed. As on SGS2 separate (!) Co-processor for processing and display photos + screen dozens of profiles for applications ...

How Makarov amolede can do "backlight shines less"? They are not here. As well as dynamic contrast. It is physically impossible. Nor nuzhna- in amoledah beautiful fair contrast 32800: 1 IPS none even close to its 1000: 1 is not lying.
