San Francisco based Osterhout Design Group (ODG), makers of the R7 enterprise-bound AR / VR smartglasses (pictured below), are developing a new AR / VR platform that is based on OLED microdisplays.
The so-called Horizon Platform offers a wide-field of view, 4K 3D content @ 120 fps and can switch between VR and AR modes. The resolution is 2K x 2K for each eye.
It's highly likely that this future platform is based around eMagin's 2K x2K OLED microdisplays - as far as I know eMagin is the only OLED microdisplay maker that offers such a resolution. In January 2016 eMagin announced it has signed a non-exclusive IP licensing agreement for its HMD technology with an undisclosed company. The deal included an upfront $1 million licensing free, and a commitment to use eMagin’s OLED microdisplays in the company’s headsets.
