The lack of a universal standard for active shutter 3D glasses became painfully clear during our 3D TV shootout last year, and gave plenty of reasons for buyers to skip the pricey specs altogether. Nine months later we see that LG has jumped onto passive 3D and CEA is playing catch up on the IR glasses problem, but many of the new HDTVs for 2011 are using Bluetooth technology to keep their glasses in sync — again without any promise of cross-manufacturer compatibility. A day late and a few dollars short, Panasonic, Sony, Samsung and universal glasses maker XpanD are announcing the “Full HD Glasses Initiative” which should lay down a standard for consumer active shutter glasses to communicate over Bluetooth or IR. The new glasses should be backwards compatible with this year’s TVs, although early adopters from 2010 have no such guarantee. The press release (included after the break) indicates we can expect the new models to arrive in 2012, assuming they haven’t lost more ground to the FPR army and can still convince buyers to even look at 3D by then.
