The problem of 3D panel display systems either requiring special glasses to separate left and right images, or having auto-stereoscopic 3D with compromised fidelity, is solved by providing, for each of a plurality of left and right sub-pixels, both means for separating the left and right image signals, and means for multiplexing the separated left and right signals to a plurality of users (e.g., gratings), such that the left image is provided to a plurality of virtual volume apertures (WAL) containing positions of the left eyes of the plurality of users, and the right image is provided to a plurality of virtual volume apertures (WAR) containing positions of the right eyes of the plurality of users. Glass-free 3D systems consistent with the present invention may treat far field optical signals from the display panel as electro¬ magnetic waves rather than as rays consistent with geometric optical theory.
