of a PenTile display on LCD technology (as best we understand), the screen also has a noticeable array of tiny black subpixels that cover the screen, further washing out color and somewhat ruining the beauty of the high - resolution display.
The V10's display is LCD instead of AMOLED, which means that the effective color resolution of the Honor V10 is higher than the Mate 10 Pro's AMOLED display, as it uses a RGB matrix instead
of a PenTile matrix, but it remains to be seen how the display quality holds up to the Mate 10 Pro's display.

of the PenTile technology that Samsung uses in its AMOLED phones.
From what I can get, this «Super AMOLED Plus» finally gets rid
of the pentile matrix and moves to the conventional (but better) RGB matrix.
Looking closely, you see a slight difference - because
of the PenTile technology of the Super AMOLED (which Samsung no longer uses in the Super AMOLED Plus display).
One of the advantages
of PenTile displays is that they last longer.
