It's very encouraging that Google chose Samsung for these micro displays as no one else could supply the volume. Perhaps not huge amount of surface volume but it also gets Samsung's (and PANL's) foot in the door for future collaborations with Google.
How this will be huge for UDC ?
Samsung has the license agreement that covers all their products.
The screens in the Google Glass are tiny , the amount of chemicals used there is microscopic.
It will add nothing to UDC revenue.
