Abstract: A display device utilizing an array of electron-emitting sources insulatively supported opposite a screen member so that each emitting source is in register with a selected area element of such screen member. Means are provided for sequentially controlling the emission of electrons from such sources so that the emitted electrons impinge in an appropriate sequence upon the selected area elements of the screen member to produce an image thereon. An appropriate stereoscopic display of such image may be provided by using optical filters adjacent each selected area element so that certain selected portions of the visible spectrum are transmitted to the receiver from each such element as a result of the impingement of electrons thereon.
