<p>FLAT PANEL DISPLAY AND METHOD OF OPERATING THE SAME An evacuated envelope includes front and back walls and a plurality of spaced,parallel supports between the front and back walls and forming a plurality of parallel channels. A gun structure at one end of the channels directs one or more beams of electrons along each of the channels. In each of the channels is at least one beam guide which confines the electrons of the beams. The beam guides include a plurality of spaced, parallel deflection electrodes extending transversely across the channels, which electrodes, under application of an appropriate potential, will cause the deflection of the electron beam out of the guides toward a phosphor screen on the front wall. In the operation of the display, a first potential is selectively applied to the electrodes to cause the beams to deflect out of the guides and impinge on the phosphor screen at a first series of spaced points along the channels, and then a second potential different from the first potential is selectively applied to the electrodes to cause the beams to be deflected out of the guides and impinge on the phosphor screen at a second series of spaced points between the points of the first series.</p> |
