<p>Parallel cathode electrodes 13, 14 extend across the base plate 1 of a display. Each electrode 13, 14 has teeth 15, 16 projecting from both sides, the teeth of adjacent electrodes being closely spaced from one another by a gap 17 that is bridged by a dot 18 of an electron emitter material. A glass screen 2 spaced by a vacuum gap above the base plate 1 carries transparent anode stripes 22 extending transversely of the cathode electrodes 13, 14 and a fluorescent layer 23 of coloured phosphors on the anode stripes. A voltage applied between adjacent cathode electrodes 13 and 14 gates conduction via each electron emitter dot 18. A voltage applied to an anode stripe 22 causes a part of the current from the emitter 18 directly below the stripe to be directed towards the anode, thereby illuminating the phosphor pixel above the emitter. <IMAGE></p> |
