The purpose of this program was to investigate the feasibility of applying the AC plasma display principle to large area, discrete element displays. Specific attention was paid to the individual cell and panel configuration with respect to cell dimensions, gas pressures, brightness, memory capability, electrical parameters, and tolerances. The influence of the panel electrode design on operational parameters was studied and an optimum electrode configuration was developed with particular emphasis on solving certain lifetime problems associated with thin film electrodes. For a panel addressing technique, the slow write and erase technique was chosen as the most advantageous one and appropriate electronic control circuitry was designed. A breadboard model using an 11 x 11 cell array with 10 cells per inch, a 100 KHz square wave sustaining voltage source, and the necessary control logic and driver electronics was constructed and tested.
