DisplayMate reviews Galaxy S8’s display, crowns it as the best smartphone display
Samsung has been improving the display quality on their smartphones every six months. DisplayMate, a brand that specializes in display calibration and optimization, recently conducted an in-depth testing of the Galaxy S8‘s display and came out pretty impressed. As per DisplayMate’s testing, the Galaxy S8 has the best smartphone display in the market right now.
The test has revealed that the Galaxy S8’s Super AMOLED Infinity Display with close to 3K resolution (2960 x 1440 pixels at 570 ppi) can reach a peak brightness of above 1,000 nits. It can accurately cover 113% of the DCI-P3 Color Gamut and 142% of sRGB / Rec.709 Gamuts, resulting in higher color accuracy even in the high ambient light. Moreover, the Galaxy S8 is the first smartphone to be certified by the UHD Alliance for Mobile HDR Premium, which means users can enjoy videos with higher dynamic range.
The Galaxy S8’s bezel-starved screen is 18% larger in screen size compared to the Galaxy S7’s screen, offering an immersive experience while using the device. Similar to the Galaxy Note 7, the Galaxy S8 has dual ambient light sensors for better control over automatic screen brightness. DisplayMate’s tests suggest that the Galaxy S8 supports four screen modes, three color gamuts, and an option to adjust the white point. Each of these screen modes is said to offer higher absolute color accuracy compared to the S7.
There seems to be an improvement in viewing angles compared to the S7’s display. The Video Enhancer mode on the smartphone provides HDR-like expanded dynamic range while watching photos and videos that don’t have HDR coding. Moreover, Samsung seems to have employed a dedicated IC in the Galaxy S8 and S8+ for the Always On Display mode which results in even lower power consumption. However, when you look at the power consumption numbers, there doesn’t seem to be an improvement compared to the S7, but Ray Soneria, President of DisplayMate Technologies said this:
“Increasing the Color Gamut of a display requires more saturated primaries, which are inherently less efficient, so it takes more power to produce the same brightness as a display with a smaller Color Gamut. The reason why all displays and all display technologies struggle to increase their Color Gamut is due to this particular issue.
Since the display power on the Galaxy S8 did not increase compared to the Galaxy S7, which has a smaller Color Gamut, that means the optical efficiency of the new OLED materials in the Galaxy S8 were improved, with a total improvement of around 10 percent.
Producing the much more saturated Red used in the Galaxy S8 is particularly challenging, which is why I mention the new “Deep Red” OLED in the article. Note that all displays are struggling to reach 100% DCI-P3, but the Galaxy S8 has 113% DCI-P3, which is impressive, and Samsung did it without any increase in display power.
