Samsung has broken all records with the Samsung Galaxy S8, and just launched Galaxy Note 8 is also in the headlines because of the massive display. Galaxy S8 display is very bright. The maximum brightness of the Samsung Galaxy S8 + with the automatic brightness is off is 360 nits, but when the auto brightness mode is activated it is able to reach 576 nits when we are under a bright light like the sun. These tests have been done, as usual, with a completely blank screen. We can settle with such brightness level with Galaxy S9 smartphone in 2018.
The best display smartphone can be defined as, if, instead of displaying the whole screen blank, we show only a white square on a black background that occupies 10% of the surface, the brightness of the white square goes off and reaches, in our tests, the 900 nits Maximum brightness of an OLED display depends on the number of pixels on). The guys at DisplayMate claim to have even managed to exceed 1,000 nits by further reducing the size of that square. So, Galaxy S8 has the best ratings in the display. If Samsung engineer plays lazy, and doesn’t do any changes then also Samsung Galaxy S9 will still be the best display phone of 2018.
In this comparative graph, however, we reflect the value with the screen completely blank, since it is the usual way to measure the brightness of a screen. As we can appreciate, the maximum brightness value is high, although in line with other high-end smartphones. This is because the AMOLED screens do not stand out in brightness against the LCD when the screen is completely white, but they do it in mixed environments with white, black and other colors pixels. Out of all this, you can simply say S8 has the best display, and Galaxy S9 will follow the trend.
S8 display offer the color black is i.e. very deep, to the point that our colorimeter has been unable to measure any level of brightness. This means that the black color is really black and that the contrast is, theoretically, infinite. One advantage of such a deep black color is that when you watch a movie, the black stripes around the image look completely black. AMOLED screens have a peculiar behavior when viewed from an angle. On the one hand the light emitters are closer to the surface, and this makes the contrast and brightness vary less as we move about the center, but on the other hand the Pentile matrix causes the colors to be distorted. So, here we have an improvement suggestion that Samsung may try to fix with the Samsung Galaxy S9.
