The advancement of technology for micro projectors has been amazing. From Texas Instruments DLP, to a plethora of LCoS manufacturers such as 3M, Syndiant, Aurora, MEMs designs from players like Microvision all these technologies have been converted into product within the last 3 years.
Now with OLED technology beginning to see commercialization will OLED lead the micro projector charge?
Hypoled seems to think so with its new OLED imager:

But judging from the prices of Sony’s OLED TV’s, perhaps we are still a little bit away from commercialization.
