Apple iPhone X has the most colour accurate display among all smartphones: DisplayMate

The Apple iPhone X has the most colour accurate display on a smartphone, says DisplayMate. The OLED display on iPhone X has also been found to offer the highest full-screen brightness of 634 nits, improving the screen visibility in Ambient Light. In comparison, the Galaxy Note8's Super AMOLED display has a full-screen brightness of 423 nits with manual brightness and 560 nits of automatic brightness in high ambient light.

The iPhone X's home screen has a brightness of 726 nits while small portions of the screen area can produce up to 809 nits. The Galaxy Note leads here with a brightness of 1,240 nits for small portions of the screen area. The OLED display on iPhone X also has the lowest screen reflectance among all smartphones, scoring high in areas like screen readability, picture quality and overall colour accuracy in ambient light.

The iPhone X is the first iPhone to feature an OLED display in favour of the LCD display found on all other iPhone models. It sports a 5.8-inch display with a Full HD+ resolution of 2436 x 1125 pixels and an aspect ratio of 19.5:9. which is taller than the 18.5:9 aspect ratio found on Galaxy Note8's Super AMOLED display. With iPhone X, Apple has adopted diamond sub-pixels for enhanced sharpness and higher peak brightness.

In Super Dim Setting, the OLED display can get as dim as 2 nits using the brightness slider but tends to exhibit a shift in colour when viewed off-angle. Apple has also published a support document detailing the shift in colour, which is natural with OLED displays and the eventual possibility of burn-in and different ways to mitigate it. DisplayMate also notes that Samsung Display needs to be appreciated for developing and manufacturing the best OLED display hardware yet for the iPhone X. However, what set it apart from the display found on Galaxy Note8 is the display calibration done by Apple.

Other observations by DisplayMate include that the iPhone X's OLED display works with polarised sunglasses in both portrait and landscape orientations. It notes that the iPhone X has the best performing smartphone display that DisplayMate has ever tested and gives the display A+ grade, highest ever for a smartphone display. It notes that the display is impressive "with close to Text Book Perfect Calibration and Performance."
