An improved color DC plasma display structure was developed and its characteristics were investigated. The configuration of the device is formed using a multiple thick-film printing technique which allows the realization of a large-scale panel. Discharge occurs from thick cathodes formed on three of the cell sidewalls. The panel developed exhibits the following improvements when compared to a conventional panel with straight row-and-column electrodes: it generates a high luminous efficiency of 0.16 lm/W (a 1.3-fold improvement with a 200-μA/cell), produces high uniformity in light output (a 1.4-fold improvement), and has an increased lifetime under accelerated conditions of 240 h at 400 μA/cell (corresponding to a 4-fold improvement at 70% of initial brightness). The mechanisms of the improvements used in the new cathode structure are discussed
