Electrostereoscopic eyewear
First Claim
1. Stereoscopic eyewear, comprising:
- a pair of liquid crystal shutters each having a contact pad for receiving electrical drive signals;
a frame having a pair of eye openings therein suitable for receiving the shutters;
an electrical cable incorporated with the frame and having a plurality of wires for providing drive signals, each wire having an end which is terminated with an electrical contact;
an electrical contact area incorporated with the frame and adapted to securely receive said electrical contacts;
an electrical coupling between the electrical contact area of the frame and respective contact pads of the shutters, said coupling including a conductive circuit trace formed on an insulating material; and
a lens assembly coupled to the frame and rigidly holding the frame, the shutters and the electrical coupling in intimate juxtaposition.

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.
