The iPhone X PenTile screen, in a single image

The iPhone X OLED display is a diamond matrix PenTile arrangement, as opposed to the traditional RGB stripe arrangement.

From Rene Ritchie’s iPhone X review:

To begin with, Apple has sourced its OLED panels from Samsung Display, which offers the best and most mature phone solution currently on the market. (Pixel 2 XL was sourced from LG Display.)

That does mean the iPhone X is stuck with a diamond pixel arrangement, which has oval green pixels with square red and blue pixels arranged around them, rather than the RGB stripe traditionally used for LCD displays. It’s a way to mitigate against the significantly lower lifespan of blue pixels in OLED, and it’s what can currently be supplied at scale.

Read the rest of Rene’s review for more detail, but bottom line, you end up with more green than red and blue.

There have been a number of pictures showing the overall look of this arrangement (including the images in Rene’s review), but I found this tweet from Steve Troughton-Smith‏ really brought a sense of what the diamond matrix arrangement meant in real life:

Tap the image and notice how much sharper the green text is than the red or blue text on either side.

With that image in mind, go back to Rene’s review and read what he has to say about the iPhone X display and how Apple gets the most out of it. Great stuff.

    To be fair a good deal of the fuzziness in the red and blue is due to them being out of focus in the image and poor contrast with the black background.

      Also, human vision is most sensitive to green light, so if all else were equal, green text should look sharper anyway.

      yeah, the red is definitely worse on the left than the right, because it’s closer to the lens. The red on the right just before it goes green is actually pretty sharp, to my eyes.
