There’s a 3DTV webinar, 3D-TV IR Receivers and Emitters, on the Vishay Intertechnology’s website. The webcast explains how infrared receivers work in 3DTV active shutter glasses. Infrared receivers are used in 3DTV glasses where they receive a synchronization signal from the 3D television set and open and close LCD shutters in each lens of the glasses to create the stereoscopic 3DTV effect.
