In search of such a display, the author went to Newton, MA, just outside of Boston to visit Kopin, a small public company. Kopin is a worldwide leader in LCOS and recently announced a new OLED microdisplay (Fig. 9). The company is well positioned in the AR industry, as it is the primary supplier of microdisplays for Google’s Glass and pro- vides the LCOS displays for the F-35 Light- ning II helmets. Dr. John Fan, CEO of Kopin, explained that if the helmets were designed today, he would probably use OLED microdisplays due to their fast response time and higher contrast.

BTW Figure 9 has wrong caption . On left is eMagin prototype .
