DisplayMate Rates the Galaxy S8

DisplayMate’s Ray Soneira has released his report on the OLED display in Samsung’s newest flagship smartphone -- the Galaxy S8. Here are a few of the highlights from his extensive report, which can be accessed in full at www.displaymate.com/Galaxy_S8_ShootOut_01.htm.

The Galaxy S8 (5.8 inches) and Galaxy S8+ (6.2 inches) have new, state-of-the-art flexible OLED displays, together with a radical new full-display screen design that fills almost the entire front face of the phone, providing a significantly larger display for the same size device.

Both models have dual-edge, curved-screen, flexible OLED displays. While the display itself is flexible, the screen remains rigid under an outer hard cover-glass that is hot-formed into a rigid curved screen. The curved screen provides two additional user-configurable edge-screen areas that can be viewed from both the front and the sides, even when the phone is placed face down. With the “always on display mode,” the edge screen can even be used as a night-time clock for your bedside table.

Below are some of the outstanding features of the Galaxy S8 (the unit tested by DisplayMate):

  • A new 3K, 2,960 x 1,440 display that fills almost the entire front face of the phone from edge to edge, resulting in a 5.8-in. display with a taller height-to-width aspect ratio of 18.5 : 9 = 2.05. (The S8’s predecessor, the Galaxy S7, had a 2.5K, 2560 x 1440 resolution display.) The display area of the Galaxy S8 is also 18% larger than that of the Galaxy S7 for the same size phone.
  • A new and accurate, 100% DCI-P3 color gamut that is also used for 4K TVs. This is the first smartphone to be certified by the UHD Alliance for Mobile HDR Premium to play all of the latest content produced for 4K UHD Premium TVs.
  • The native color gamut of the Galaxy S8 is the result of its new, high-saturation “Deep Red” OLED, resulting in a very impressive 113% of DCI-P3 and 142% of sRGB/Rec.709 gamut. It also produces better on-screen colors in high ambient light.
  • The Galaxy S8 has 5% to 19% higher screen luminance than its predecessor, plus a record peak luminance of over 1,000 nits.

The Galaxy S8 is the first in a new generation of OLED smartphones. OLEDs have now evolved and emerged as the premium mobile smartphone display technology. More than two dozen manufacturers already make OLED smartphones, and the full-screen display design using a flexible OLED will be the new standard for all future top-tier smartphones. In short: The Galaxy S8 is the most innovative and high-performance smartphone display that DisplayMate has ever lab tested, earning a highest-ever grade of A+.
