recent “red rice Note2 screen incident” caused the industry’s brightest people, including many users and digital enthusiasts view the phone screen. We, as a review mechanism, on publicity millet right and wrong is not the scope of our discussion, we are here only to discuss the performance of this screen itself. In addition, we found that everyone on the phone screen parameters of understanding, there are some deviations, in which we simply give everyone universal look, while four red rice Note2 high version prototype at hand, and a nut phone, a charm Blue Note The screen on the comparison.
First of all we have to say under the gamut, Gamut The concept is complex, most people feel that “the more wide color gamut better, more wide color gamut representatives to show more colors . “This sentence first phrase of the half, and then the last part of it is wrong.
The current reality is that we are usually the Internet, watch videos, see pictures, standard color gamut displayed on the computer, mobile phones used are sRGB, so-called wide gamut of AdobeRGB, and NTSC color gamut applies only to areas of expertise, even if you use a 100% NTSC color gamut / AdobeRGB screen using this device to the Internet, what you see is only a projection from the sRGB color gamut to content NTSC / AdobeRGB color gamut on ʱ??
Since the scope of these two large color gamut than sRGB, as you see in the Internet color coded as (0,255,0) green when, if the color gamut covering 100% of just good sRGB color Time Domain, you see will be the web production expressed by people who want to “green”, this time if your screen covered 98% AdobeRGB, Because of the wide color gamut, the system code (0,255,0) The green onto 98% AdobeRGB becomes more rich and gaudy green, this time you see the contents have been unreal.
If only to sRGB, naturally, is to cover more of the sRGB color display that will be more accurate, but if the screen’s color gamut is too large, far beyond the sRGB range, also covering more than 90% of AdobeRGB / NTSC, then the colors will definitely be too gaudy (oversaturated). Similarly, if the color gamut is too low, it will also color reproduction are not allowed, so the gamut phone screen is not bigger is better, but closer to 100% sRGB color gamut, display color will be more accurate.
NOTE: (iPhone6 color gamut is very close to 100% sRGB, while Samsung’s SUPER AMOLED ultra-wide color gamut, but in the Galaxy series, you can adjust the screen color is rich and gaudy color gamut, Galaxy S6 in the basic mode selection screen, ultra-wide color gamut narrowed to nearly 100% sRSG, so in the basic mode Galaxy S6 color reproduction is quite accurate.)
And here we say that “The more wide color gamut representatives to show more colors” this wrong, we look at the phone screen and computer screen time will see a parameter called the “16 million colors”, so-called 16 million color refers to the screen that can display 16 million kinds of color, which is 8bit screen , on the device, we have three colors red, green and blue 256 (2 ^ 8) species, which 256 shades of red, 256 kinds of green, then a combination of 256 kinds of blue, which is 256 * 256 * 256 = 16,770,000, that is, we are talking about 16 million colors.
On the computer / phone them in coded form, such as (0,0,0) represents black, (255,255,255) represents white, (0,255,0) is pure green, a good question , we are now all phones available in the market are based on the 16 million color screen panel they can only display 16 million colors, but there is a wide gamut, with a conventional color gamut, it also displays a wide color gamut of 16 million colors , except that they display 16 million colors, this color and normal of 16 million 100% sRGB color is not the same, that is, when it comes to saturation above us will be higher because of the wide color gamut, with a point (0,255 , 0) Green at wide gamut displays more green, and happens to be 100% sRGB is the normal display.
professional displays will reach the so-called one billion colors, which is 10bit screen panel, wide color gamut screen which was more meaningful.
It is worth mentioning that the wide color gamut of the screen when watching movies wonders, since the color saturation, some users will feel well (although the color already and original animation group want to show With the effect of certain differences). Of course, the color gamut is only one screen in the parameters, the quality of the screen involves many aspects and parameters, and in this, but to say so-called “color gamut” is closer to 100% sRGB, the closer the effect display true.
Next we look at red rice Note2 high version, are using Sharp / AUO’s 5.5-inch nut phone charm Blue Note’s screen data, nuts and charm Blue Note phone use 1080P screen, and red rice Note2 high version to use is to use the Pegasus / AUO’s 5.5-inch 1080P screen (our of four red rice Note2 high version Upon inquiry, all Pegasus screen).
From the parameter point of view, Although red rice Note2 high version using Pegasus screen, but in color gamut, color temperature, color deviation terms are not bad , the degree of deviation in color Blue Note on comparative charm Sharp / AUO screen has a large advantage, but also the default color temperature color temperature closer to 6500K, also covering the sRGB color gamut better than charm Blue Note, but the maximum brightness is definitely far more charm Blue Note Note2 phone red rice and nuts.
The nuts are also using the phone’s screen Sharp / AUO, in terms of color deviation nuts screen better, and the color temperature is colder, the brightness lower.
Loom from left to right are red rice Note2 prototype No. 1, No. 2, 3, 4, charm Blue Note, nuts phones
In the viewing angle, red rice Note2 high version and nuts phones are no problem, what the situation cast diagonal death did not occur, or the Blue Note and charm in the tilt is a serious color cast situation that at very diagonal Obviously, the last picture because the camera angle is different for each machine is in itself meaningful comparison, but we can see that only Charm Blue Note a serious color cast, while others loom just normal brightness attenuation, which nuts the best phone’s camera position, and the shooting angle red rice Note2 high version the 1st prototype of the worst.
In judging the quality of a screen when we certainly can not look at the screen manufacturer, which is like saying that certain Sony Samsung mobile phones as well, so 1000 was really better than Samsung phones the Sony Xperia Z3 it? Even with the big names also have product positioning, market so much Samsung AMOLED screen, but they are far inferior to display good piece AMOLED screen on the Galaxy S6, the same not all Sharp / AUO screen than the Pegasus screen Well, Pegasus screen data, and the actual use and there is absolutely no difference seen as a third-party evaluation agencies, we need to tell the user more objective and scientific results.
