Google's VR vice president, Clay Bavor, revealed that Google has partnered with "one of the leading OLED makers" on a secret project to develop a high-end VR display. The OLED display will support a resolution of 20 million pixels per eye.
This is a very high resolution - a 4K display has 8.3 million pixels, so it means 2.5X the number of pixels in a 4K display. It terms of display density (which depends on the panel size of course, which we assume to be around 3.5"), this could be around 1,800 PPI.

Previously eMagin has tiled microdispays and so has Sensics - to achieve higher resolutions .

eMagin has a patent application for a manufacturing process which would eliminated seams when tilling micro displays - US9899456B2.
LARGE AREA OLED MICRODISPLAY AND METHOD OF MANUFACTURING SAME FIELD OF THE INVENTION
eMagin could easily achieve 20 mp per eye by tiling or using the manufacturing process in the patent application as follows :
1. Their current 2k x 2k display = 4 mp . Making a slightly larger display at 2.25k x 2.25 k = 5mp
Tiiling 4 - 2.25k displays or combining them as per the manufacturing patent app = 20 mp .
2. eMagin has talked about a 4k x 4k resolution display at their 1Q 2016 CC :
"We're also looking to build the prototype display that is 35 millimeters by 35 millimeters, which we could design with a resolution up to 4,000 by 4,000. We're discussing this display with potential foundry partners and we’ll bring the proposal to a half dozen likely customers who are looking for displays of this type. The customers with whom we've discussed this display are very interested in our proposal."
4k x 4k = 16 mp
A slightly larger display at 4.5k x 4.5 k = 20 mp
The dimensions of a 4.5k x 4.5k display would be calculated by taking pixel spacing a 9.3 microns x 4.5k = a 1.65" x 1.65" display . This display could be used with their current optics - pancake lens w/ fiber optic faceplate - to achieve a FOV larger than the 2k x 2k prototype of 110 degrees
20mp per eye in a compact form factor is easily within eMagin's reach IMO
Another thing that may be relevant is that Jerry Carollo who helped developed the eMagin "steam punk " prototype with 2k x 2k resolution , is now Optical Architect at Google .
Special Projects; System architect and inventor of the "Steam Punk" Virtual Reality goggle. The VR goggle has a 100 degree Field of View (FOV), 2K x 2K resolution in a very compact light weight form factor is the highest performance VR HMD ever produced.
Google and Sharp team up on LCDs for virtual reality
- another indication Google may choose to consider eMagin as they look for alternative sources to Samsung OLED .
Thanks Frank, this is certainly interesting and I agree that eMagin should not be ruled out. It is certainly a leading OLED developer. It will be great to see Google use eMagin's technology in a future HMD!
