OLED microdisplay maker eMagin developed a 2K x 2K OLED microdisplay based VR HMD, which is now being offered to partners (the company's first licensee is probably ODG). The company is also developing its next-gen 4K OLED microdisplays.
Reaching out to first-tier customers means that eMagin will need to produce a massive amount of microdisplays at a relatively low cost - which it cannot do with its current production equipment and capacity. The company will upgrade its production fab, but that won't be enough and eMagin already stated that it is in talks with potential foundry partners.
It was rumored that AMD is one of those potential partners, and indeed in the video above (at around 3:00) you can see AMD’s Corporate Vice President Roy Taylor talking about AMD's collaboration with eMagin. It seems though that these two companies are no longer working together (Roy says that AMD "have worked with eMagin for a little while").
