If you have a 3D TV that support the MPO file format, you can view the images by connect the memory by USB or directly in an SD slot. I regularly view 3D photos taken with the W3 on a Panasonic Viera 3D TV.
The Panasonic does not support the 3D film format (some variant of AVI, where they include a second video track), as far as I can tell. However, another option is to connect the camera to the TV with HDMI (there is a mini HDMI connector behind a panel on the camera). Make sure your cable supports 3D.
If your TV supports some other format, you can usually find software that will batch convert the files on your computer.
So you don't need the screen, although the screen is cool because it uses the same no-glasses-needed 3D tech as the camera's smaller screen.
