Glass LCOS power draw study, recommends OLED

Efficient Projection: The LCOS projection consumes two

orders of magnitude more power than its proximity requires,

due to luminance drops in the display path. Replacing this

projection with a transparent OLED screen in front of the

eye would reduce power draw by avoiding luminance drops.

Moreover, the see-through nature of OHMDs means that for

many apps, few pixels are active at any time. This is optimal

for OLED, as inactive pixels do not draw power.

So who makes a transparent

So who makes a transparent OLED microdisplay other than the Fraunhofer prototype ?
