Samsung introduced the Diamond Pixel display architecture back in 2013 when it launched the Galaxy S4 smartphone, and since then it has adopted this sub-pixel scheme in all of its OLED displays (replacing the previous PenTile scheme).

The 2014 Galaxy S5 introduced a different Diamond Pixel scheme which Samsung uses till today. DisplayMate tested the Apple iPhone X and it turns out that Apple`s OLED, even though it is produced by Samsung Display, uses a slightly different Diamond Pixels - the fill factor of Apple`s display is higher than in the Galaxy phones. You can see the two different displays in the macro photos above (courtesy of Display Mate). The iPhone X OLED is on the left, while the right shows the Galaxy OLED.
