As the sole supplier of the OLED displays used in the upcoming iPhone X (and one of the main suppliers of NAND flash memory used in the phone), Samsung is poised to make quite a bit of money on total sales if the iPhone X is as successful as some estimates are guessing.

I'd also like to know if the iPhone X display is true-RGB / full-matrix, or Diamond PenTile like the ones Samsung uses in their own phones. I think that has fairly significant bearing on how much of a step forward this can be considered to be.
