Great Resource for VR/AR/HMD : He works for SA-Photonics so you know, he's going to like them but the eMagin OLED Microdisplays get some glowing praise

The SA-55, and its sister the SA-30, were the first full HD OLED HMDs I had the chance to use and it made me a firm believer in using OLED microdisplays. The imagery is quite beautiful. The colors are very brilliant and the blacks very deep. The FOV of the 55 also provides a good level of immersion and at the same time maintains an acceptable resolution.
