Self scan panel with ionised gas cells at intersections of electrodes - has rows of holes in cathode strips at right angles to first and third set of electrodes

摘要

The self scan panel contains an insulated base block with parallel slots each containing an electrode strip. A second set of parallel electrode strips is placed at right angles to the slots. Each strip contains a number of holes made by a laser. The points of intersection of the two sets of electrode strips form a matrix of ionised gas cells. The base block is then covered by an intermediate block with holes over the junctions forming cells. This is then covered with a top plate containing a third set of electrodes in complimentary slots parallel to the first set. These are used as anodes. The three sections of the blocks are then hermetically sealed.
