Both the iPhone XS and the iPhone XS Max use a new generation of OLED screens. It is also officially called “Super Retina HD Display” by Apple.
Except for the size and resolution of 2436×1125 and 2688×1242.
There are no differences in other parameters, all of which are 458 PPI, P3 color gamut.
Color gamut test
The iPhone XS series LCD, like all previous iPhones, does not have a so-called screen color mode switch, which is because the iPhone is equipped with iOS, which is the world’s most complete mobile device operating system with color management.
After the introduction of the P3 color gamut in the iPhone 7 series, all iPhones can display the correct color according to the color configuration of the image content itself. It does not need to be manually switched to the sRGB mode to avoid color over the same as the Android device. saturation.
The first step in testing the gamut
This is also confirmed in our actual measurements. First, we do the first round of testing with the Safari browser or other non-declarative P3 color gamut app:
When the iPhone XS series displays sRGB content.The color management is correct, and the color gamut is mapped to sRGB.
So the color gamut is covered: 99.7% sRGB， 71.7% Adobe RGB，73.9% DCI P3。
This means that all sRGB content can be perfectly displayed without missing colors. However, we can also find that its gamut volume slightly exceeds sRGB, reaching: 104.7% sRGB，72.2% Adobe RGB，74.2% DCI P3.
By using the UV mode gamut coverage map closer to the human eye in the above picture.
So we can easily see that it is actually slightly out of orange and blue.
Because there is not more than a lot, so for the mass users.
And they have a certain For professional users of professional demand, no difference will be found without professional instrument testing.
The second step in testing the gamut
Therefore, we continue to use the special P3 color gamut app to test whether the iPhone XS series can cover the P3 color gamut:
The result is also very obvious. It Compared to the black triangle (sRGB) in the center area.
The iPhone XS series can display a wider color gamut (white triangle) .And it reach the P3 level (a larger black triangle).
We can also find that The iPhone XS in our hands has a certain lack of red in the upper right corner of the triangle, and there is still a gap between it and P3.
However, ignoring the test error, the iPhone XS series can indeed reach the P3 color gamut.
It can display the correct color according to the color configuration of the image content, instead of mapping the color chaos like the operating system without color management, which ultimately leads to A saturated condition occurs.
Finally, we also tested the backlight spectrum of the iPhone XS series. It can be seen that due to the OLED, the distribution of red, green and blue colors is obvious.
Especially red light, which can reach longer wavelengths. This is also the iPhone XS series can display P3.
An important reason for the color gamut, because the P3 color gamut is relative to sRGB, the main addition is the red display capability.
In the color standard, Apple declared: “iPhone XS uses the most accurate OLED display panel in the iPhone”.
So although it has not mentioned that it has the appearance of school color, but from the performance of the iPhone in previous years.
The actual effect It is also close to the school color.
That is to say, such a screen performance, not only the human eye is difficult to see the color difference.
And even if the iPhone XS series is placed in front of a calibrated professional display, there is almost no difference in comparison.
The iPhone XS series is still the best smartphone with the highest screen color.
At the same time, we also tested the color temperature performance of the iPhone XS series.
What is interesting is that when we turn off the automatic brightness and the original color display.
The color temperature of the iPhone XS Max in our hands is 6650K.It should be noted that due to the OLED.
The iPhone XS still has a screen flicker phenomenon caused by low-brightness PWM dimming.
When the screen brightness is lower, the phenomenon will become more obvious.
The above is the report of iPhone XS Series LCD Quality.
