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.
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application No. 60/014,296, filed Mar. 29, 1996 pending.
The adhesion of a sputter-resistant layer is improved by providing the layer with a fairly high quantity of glass frit, in which the frit and the sputter-resistant material have a mass ratio M.sub.frit /M.sub.srm of 0.9 or more.
A channel structure for a PALC display panel comprises a channel member defining at least one channel, a cathode having an upper surface exposed in the channel, and an anode having an upper surface exposed in the channel. The upper surface of the anode is of substantially uniform composition and has a conductivity perpendicular to its upper surface of at least about 10.sup.-4 ohm.sup.-1 cm.sup.-1.
A reflective display is formed using two orthogonal fiber arrays and an electro-optic material. The bottom fibers contain plasma channels, used to address the electro-optic material. Wire electrodes built into the fibers address both the plasma and the electro-optic material. The fibers are composed of glass, plastic or a combination of glass and plastic. Color is imparted into the display using colored fibers, adding a color coating to the surface of the fibers, or adding the color to the electro-optic material. The electro-optic material consists of a liquid crystal material, electrophoretic material, bichromal sphere material, electrochromic material, or any electro-optic material that can serve to create a reflective display.
