Improvement of Luminance and Luminous Efficiency Using New Electrode Structures in AC Plasma Display

Two new electrode structures, namely, fence electrode (Fen) and combination of coplanar and fence electrodes (CoFen), employing an elevated bus electrode in the conventional surface discharge structure with three electrodes are suggested. In this paper, various comparisons between the conventional and two new structures are made to validate the effectiveness of the proposed structures. The firing and sustain voltages, displacement and discharge currents, cell capacitance, luminance, and luminous efficiency for three electrode structures are measured for various pressure ranges used in the conventional plasma displays. Consequently, the experimental results show that the CoFen structure has lower firing and sustain voltages than the conventional and Fen structures for all pressure ranges from 100 to 700 torr. In addition, the Fen structure realizes over 80% brighter and approximately 18% higher luminous efficiency than the conventional one.
