But Vizio is bringing that tech to the consumer level.  Later this month, the company is slated to show a 65 inch 3D HDTV that uses passive technology, which means it'll be a lot easier to pick up a handful of spare glasses for when friends come by.
 
The cost of the set hasn't yet been revealed, but from what we know of 3D technologies, a passive display is an expensive display.  It's sort of a trade-off.  Cheap glasses, expensive display.  Expensive glasses, cheap display. We'll certainly find out more next Tuesday, when Vizio kicks off the CEA Line show with a press conference on June 22nd.
