Sony’s Active Shutter 3D Glasses Battery Life Revealed

We’ve spoken to a high level Sony representative about some specifics regarding their upcoming 3D strategy as there are still many questions out there. One of the most important aspects of the upcoming 3D home theater experience is the active shutter glasses that you must wear to enjoy the experience. Active shutter technology is far different than the plastic polarized glasses one may have used at a movie theater – click here to learn more. Sony Japan recently gave us an idea about how much this necessary accessory would cost, but we were still unsure about a very important fact: battery life.

Sony expects the battery life for the TDG-BR100 and TDG-BR50 active shutter 3D glasses to be 100 hours of use. The glasses are only in use when they receive the 3D sync signal from the TV, otherwise they go into standby mode with no drain on the battery. At launch time Sony will only offer battery powered glasses, and have not detailed induction-based (e.g. Powermat) models. We were pleased to learn that you can also use as many glasses as you want as long as they can receive the IR signal.
