Abstract:
An auto-stereoscopic display device comprising:a plane viewing screen; a plane cathode; a plane permanent magnet; a two dimensional array of rows and columns of channels extends between opposite poles of the magnet for receiving electrons from the cathode;a phosphor layer is disposed between the screen and the magnet and having a plurality of pixels each corresponding to a different channel;grid electrode means disposed between the cathode and the magnet for selectively controlling flow of electrons from the cathode through each channel to the corresponding pixel in response to input video data;deflection anode means disposed on the side of the magnet remote from the cathode for sequentially deflecting, orthogonally to the columns, each electron beam to different parts of the corresponding pixel preselected for alignment into respective offset stereo image pairs in response to an input video clock signal; anda lenticular lens array disposed between the phosphor layer and the screen and having a plurality of cylindrical lenses each corresponding to a different column of pixels whereby the stereo image pairs are separated for viewing.
