ABSTRACT:
An electron beam guide assembly for a flat panel display device includes an acceleration electrode having two portions separated by a longitudinal slit. The display device also includes electrodes on support walls which divide the device into channels. By properly voltage biasing the acceleration electrode portions and the support wall electrodes, an electron beam is simultaneously directed to a particular color producing material and transversely scanned across the channels. A color display, therefore, can be produced using one electron beam per channel.
