The objectives of this program are to design, fabricate, and evaluate a plasma-panel display device having a three-color capability and to investigate and develop a technique for operating such a device with at least three levels of intensity. Red, green, and blue phosphors were selected for incorporation into three-color, triad DIGIVUER displaymemory panels. It was found that multicolor panels containing Xe gas and having phosphor projecting into the gas volume require the phosphor spots to have a donut geometry which keeps the area of electrode overlap free of phosphor. A high-voltage square-wave driver was completed which is capable of addressing Xe-filled panels. Optical crosstalk was measured and found to be significant. Modifications of panel structure intended to reduce optical crosstalk were begun. In particular, abrasion of the inside surface of the back plate was found to decrease optical crosstalk. Procedures for determining the change in wall-voltage Delta VW versus the cell-voltage VC are reviewed. Typical Delta VW-versus-VC-versus-time characteristics were measured, and their significance is discussed. Author
