Characteristics of ACPDP test panels with aluminum fence electrode formed via anodic bonding with soda-lime glass

Abstract

In an attempt to reduce materials and processing costs of ACPDPs, aluminum fence electrodes were prepared on soda-lime glass substrates by chemically etching aluminum foil bonded directly onto the substrate via an anodic-bonding process. Several different fence-electrode patterns were designed and coated either with a glass dielectric layer or with an anodic aluminum oxide layer. Firing voltages, operation margin, luminance, and luminous efficiency of such test panels were evaluated. The results indicated that the performance of test panels with aluminum fence electrodes is comparable with conventional test panels with ITO/Ag electrodes, demonstrating the possibility of a dramatic reduction in the costs of ACPDPs.
