Materials and Manufacturing Issues for Color Plasma Displays

Abstract

Recent demonstrations of color-plasma displays with exceptional image quality and performance that meet and in some cases exceed that of cathode-ray tubes (CRTs) have resulted in a renewed interest in this 25-year-old technology. The tremendous market potential for large-area plasma displays for both home-entertainment and computer applications now appears to be an attainable goal. This new generation of plasma displays features full color capability, high brightness and contrast ratio, wide viewing angles, and rapid refresh rate. The success of today's plasma displays is the result of the integration of advancements in driver electronics and the materials and processes used in the fabrication of the plasma-display structures.Using color-plasma technology, two-inch-thick direct-view displays can be made that are up to 60 inches in diagonal. During the past several months, numerous articles have appeared in the media announcing major investments in facilities and technology for largescale manufacturing of these large-area plasma displays. Table I lists the companies committed to plasma-display research and development. Additional advancements in materials, processes, and electronics will be required to achieve high-volume, low-cost manufacturing.
