"SA Photonics showed an incredible Head Mounted Display (HMD) at SID 2013. This uses the brand new eMagin 1920×1200 resolution panels. Image quality of wonderful with a 30-degree field of view with excellent optics and good eye relief. It was also designed to allow some look around capability.
It is also 3D as there is 100% overlap. Alignment of the panels is critical for good 3D in this case. The resolution is a little better than 20/20.
This is a $40K plus HMD so is aimed at military and very high-end medical or architectural applications.
