Bi-directional OLED microdisplay for interactive HMD

First prototypes of bi-directional OLED microdisplay devices have been designed, that combine both display and camera functionality on a single CMOS chip (OLED-on-CMOS). Major aim of this integration is to provide capabilities for eye-tracking in see-through HMD to achieve gaze-based human-display-interaction, e.g. in augmented-reality applications.
