A few months ago we reported that Oculus VR's CEO hinted that the company aims to adopt an OLED display (instead of the current 7" LCD) in their upcoming head mounted display (HMD), the Oculus Rift. Yesterday at CES the company unveiled their latest prototype (called Crystal Cove), and indeed it uses an OLED.
Oculus chose an OLED because they really want a low persistence display. They say that "it’s incredible the difference low persistence makes... It’s mind-blowing.". The OLED display runs at a high refresh rate - it switches in well under a millisecond - faster than any LCD monitor on the market. In fact, the company says that this is also much faster than any other OLED panel on the market.
