Hon Hai Precision Industry revealed today that Google has bought some display related patents from them.
These patents are mostly related to Head Mounted Technology which is used in Google Glass type devices.
The company did not reveal any further information. It looks like Google needed these patents for the mass market launch of Glass next year.
Foxconn is of course not known as a developer of new technologies. They are mostly known as the mass manufacturers of Apple iOS devices like the iPhone for Apple.
