ABSTRACT:
This invention is a resistive layer (112, 122) for electrodes (30, 62) comprising at least one partially conductive compound and describes processes for coating the electrodes by way of cataphoretic deposition and/or screen printing of particles of at least one partially conductive compound. A second class of particles, known as a "frit," is also deposited or screen printed. In the subsequent one hour firing, these particles melt and thereby bond the partially conductive compound particles to the electrodes. This invention is also plasma addressing structures (110, 120) in which particles of at least one partially conductive compound are deposited on the electrodes of the display by cataphoretic deposition and/or screen printing. The resulting electrode structures limit and uniformly distribute discharge currents (102) in the operation of ionizable gaseous medium (90) devices, such as plasma addressed liquid crystal displays.
