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.
