ABSTRACT:
A method and an apparatus is disclosed for converting a video signal to a visual display on a device (10). The device (10) comprises an electromagnetic beam generator (12). An electro-optic modulator (14) modulates the beam (11) in response to the video signal. The beam (11) is focused and delivered to impinge a photocathode screen (36) in an evacuated envelope (30). Within the envelope (30), spaced apart from the photocathode screen (36) is a phosphor screen (38). The photoelectrons released from the photocathode (36) are accelerated and directed to impinge the phosphor screen (38).
