Update: eMagin published a statement saying that these companies (Apple, LG, Valve, Stillwater and Immerex) in fact did not participate in the offering.
On January 2018 OLED microdisplay maker eMagin announced that it plans to raise $11.5 million in an underwritten public offering, which closed on January 29. It turns out that eMagin's SEC filing specifies five investors - Apple, LG Display, Valve Corporation, Stillwater Holdings and Immerex.
eMagin has been saying that it is working with large companies ("Tier-1") on its consumer VR technologies, and it is a very encouraging sign to see this impressive list of new investors. Apple's AR and VR plans are still unknown, but it has been assumed for a long time that Apple is looking into OLED microdisplays, and it's interest in eMagin is not a surprise. LG is also interested in VR and AR displays, and is reportedly collaborating with Google, and it's great to see it investing in eMagin as well.
US-based game developer Valve is developing its own VR and AR technologies, and has recently actually said that advances in LCD make the cheaper displays suitable for VR applications. Microdisplay-based VR offer many advantages over smartphone-sized VR, though. Valve's involvement with eMagin was speculated in our discussion forum in April 2017.
