    Abstract: In a display device which is divided into a plurality of channels by support vanes, scanning electrodes are arranged on both sides of the vanes. The scanning electrodes are segmented in the direction of electron beam propagation and one portion of the segments is biased with a varying voltage to scan the electron beams transversely across the channels. The remaining portion of the scanning electrodes is biased to deflect leakage electrons away from the screen to thereby improve the visual display.

    Abstract: An improved electronic display device, comprising an inner vacuum blister having a mutually separated front wall and a back wall, a phosphor screen disposed on the inner surface of said front wall and means for generating an electron beam and directing said beam in a path generally parallel to said front wall and through it, characterized by means (29, 40) arranged along said beam path to cause said beam to travel both in an undulating path (38, 48) substantially confined with the corrugations of it approaching and moving away from said phosphor screen (28, 128, 228, 328), so as to selectively divert said beam out of said path towards said screen at selected points along said path.

    Abstract: In a flat panel display device including spaced parallel guide meshes between which electron beams propagate, the guide meshes are formed to include projections extending into the electron beam propagation space. The projections restrict the electron propagation space in a direction perpendicular to the planes of the guide meshes and thus capture electrons near the extremities of the space.
