Avegant’s new Virtual Retinal Display

Avegant unveiled a prototype virtual retinal display (VRD) delivers insanely sharp definition and a realistic image even with low-resolution sources by projecting directly into each eye

"Note that this also puts the field of view of the virtual image entering the eye somewhere between a 24.3° diameter circle and a 24.3° by 43.2° rounded rectangle."

It projects images that appear as 80-inch panels viewed from eight feet away similar to a Vuzix's Wrap glasses, MyVu, Sony's HMZ-T1 and not the Oculus Rift which had head tracking and a wider field of view.

Rather than relying on a set of high-resolution LCD displays placed close to your eyes it actually projects images directly onto your retinas from a micromirror array, which gives it a number of advantages over LCD-based headsets.

The HMD, which can handle 240Hz content (and beyond) , two separate WXGA (1,280×768-pixel resolution) images at each eye, which is essentially double the effective resolution of currently-available Oculus Rift developer kits. Additionally, since these images are being generated with reflected rather than emitted light, they more accurately mimic the way we see in the real world. Pixels blend together more naturally this way, and, since there’s no screen anywhere, the wearer won’t experience the dreaded “screen door effect” that generally occurs when LCD’s or OLEDs are placed close to the eye.
