Samsung 3D glasses for its 3D LED, LCD, and plasma TVs cannot be used with other TV brands. The electronic shutter 3D glasses will come in three versions: One powered by an internal rechargeable battery (US$200), another with a replaceable coin-sized battery (US$150), and a smaller set of rechargeable glasses for children (US$180).
The model with battery offers about 400 hours of use between batteries, while the rechargeable units should be charged fully before watching an average-length movie.
The same Samsung 3D glasses will provide an identical 3D viewing experience whether they are used to watch movie on LCD and LED panels or plasma screens. Samsung’s representative explained that plasma screens do not refresh image the same way as LCD and LED panels. Samsung’s LED and LCD Tvs provide a 240Hz refresh rate, the glasses refresh at half that rate (120Hz) because they synchronize to 3D content by alternately closing and opening each side.
