Abstract
A pair of stereoscopic eyewear includes an element for integral assembly with the eyewear including a conductive circuit trace. The conductive pattern provides electrical contact between a contact area of the frame (which is hardwired to an electrical cable) and the contact pads of the liquid crystal shutter pair. Preferably, a conductive elastomer is used to facilitate the electrical contact to the shutters and the frame. Additionally, each wire of the cable is terminated with a fixed electrical contact adapted to securely mate with a slot in the frame that correspond to the contact area. A lens assembly attaches to the frame to rigidly hold the frame, the shutters and the conductive trace in intimate juxtapostion.
