ABSTRACT:
A thin vacuum panel cathode ray display device for providing visible information upon a phosphor layer, on a viewing wall, in response to electron beam excitation. Electron beams are generated by cathodes on an electron source wall spaced from the viewing wall. The cathodes comprise an array optical waveguides each coated with a photoemissive material. Between the cathode array and the phosphor layer, and adjacent to the cathodes, is an array of grid members for selectively controlling the flow of electrons to the phosphor layer in response to low voltage signals applied to the grid members. Light energy is sequentially introduced into each of the waveguides while simultaneous control signals are applied to all of the grid members to provide line-at-at-time information display upon the phosphor layer.
