Google only just unveiled the Nexus 6P a couple of days ago, but we didn't know who made the 5.7-inch QHD panel. Well, Samsung has come out and confirmed it has provided the WQHD panel for the Nexus 6P, on a post on Reddit.
The post reads: "It has a Samsung WQHD AMOLED panel. We have spent a lot of time tuning the white-point and color gamut for these panels - hope you will enjoy the accuracy of the display. Yep, confirmed: Nexus 6P has the latest generation panels from Samsung. One of things we deeply care for is the quality and accuracy of the display through which all of us connect with the stuff we care about. We created a very tight spec (white-point temperature, delta-E variance, color-space accuracy, etc) for the 6P WQHD AMOLED panel, so it was important that we use the most cutting edge panel technology available".
