ABSTRACT:
An image display device has a plurality of electron guides for guiding electron beams to different areas of the device's cathodoluminescent screen. An image is displayed on a device by generating a plurality of electron beams and modulating each of the electron beams with the image information. The beams are directed into one group of a plurality of adjacent electron beam guides so that each beam is directed into a separate guide. The electron beams are then sequentially switched into the next group of adjacent guides until each electron guide has had one beam directed into it.
