After the press conference blitz of today, I snuck off to Panasonic's booth (still under construction) to check out their 3DHD technology—a 3D plasma screen that runs in true 1080p.
Before you read any further, I'll answer that nagging question. Yes, you need to wear special glasses.
The demo system starts with a retrofitted 103-inch Panasonic plasma. Coupled with active shutter glasses, a Blu-ray player feeds a 120fps 1080P signal to the television. 60fps are for the right eye while the other 60fps are for the left. IR syncs the glasses to the Blu-ray player to the TV, and presto, 3D magic is made.
