An autostereoscopic lenticular screen has a lenticular screen held in juxtaposition with a display surface. The lenticular screen has lenticules disposed on one side thereof and a smooth surface on the other side thereof. In one aspect of the invention, a closed chamber is formed over the lenticules. In order to deactivate the refractive properties of the lenticular screen, and thereby view the display in a planar mode, an optically clear fluid, such as a fluoropolymer, is introduced into at least a portion of the closed chamber. In order to activate the refractive properties of the lenticular screen, and thereby view the display in a stereoscopic mode, the optically clear fluid is removed from the closed chamber. In a particularly preferred arrangement, the lenticular screen is oriented such that the lenticules face inwardly toward the display screen, and the smooth surface of the lenticular screen is coated with an antireflective material.

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.
