In PDP, bus electrode should have low resistance for high efficiency. The transparent dielectric affects the shape change of bus electrode during the firing. These are related with the electrical property of the electrode. In this study, the shape of electrode was controlled by firing schedules of the transparent dielectric and the bus electrode.

In this paper, we propose IBS(ITO-BUS Separated) electrode structure. BUS electrode lines are placed apart from the ITO electrode lines, and they are electrically connected with vertical auxiliary electrodes. We varied the lengths of the vertical electrodes as 70, 120, 320um. The highest luminous efficiency and the largest IR emission peak were obtained for 70um length.

In this study, we have investigated the availability of the electroless Ni-B plating for a diffusion barrier of the bus electrode. The Ni-B layer of 1$\beta$: thick was electroless deposited on the electroplated Cu bus electrode for AC plasma display. The layer was to encapsulate Cu bus electrode to prevent from its oxidation and to serve as a diffusion barrier against Cu contamination of the transparent dielectric layer in AC plasma display. The microstructure of the as-plated barrier layer was made of an amorphous phase and the structure was converted to crystalline at about 30$0^{\circ}C$. The concentration of boron was about 5∼6 wt.% in the electroless Ni-B deposit regardless of DMAB concentration. The electroless Ni-B deposit was coated on the surface of the electroplated Cu bus electrode uniformly. And the electroless Ni-B plating was found to be an appropriate process to form the diffusion barrier.

In this paper, we investigated the relationships between the position of bus electrode and discharge characteristics in ac PDP with VGA resolution. The double bus electrode lines at the edge of ITO electrode are placed in order to lower the firing voltage. As a result, static margin and dynamic margin for the PDP with double bus electrodes was about 10V lower than conventional type.

In a conventional plasma display, the bus electrode was located on the ITO electrode at the outer part of each cell. We propose a new electrode configuration using vertical auxiliary electrodes which play a role of electrically connecting ITO and bus electrodes with the aim of enhancing discharge and luminous characteristics of the PDP (Plasma Display Panel). In this paper, luminance and luminous efficiency of the 3 in.-diagonal test panel are measured with various number of vertical auxiliary electrodes such as 2, 50 and 150. The change in the luminous characteristics is explained in connection with the discharge characteristics of the PDP cells such as current peak, IR emission peak and ICCD picture image.

In this paper, we investigated the relationship between the position of bus electrode and address time, luminance and luminous efficiency in ac PDP of 50in. XGA resolution. When the bus electrode was placed in which was about $140{\mu}m$ apart from discharge gap, the luminous efficiency was the highest and address time was the least. Whereas, when the bus electrode was placed in the edge of ITO, the luminance was the highest.

In PDP, a transparent dielectric is formed on a front glass substrate so as to cover bus electrodes (Ag). During the fabrication process, sometimes, a transparent dielectric reacts with bus (Ag) electrode in the range of $560-600^{\circ}C$, and the reaction gives the dielectric its yellow coloration, what is called "yellowing phenomena". In this paper, we investigated the reaction between bus electrode and transparent dielectric covered with different frit content in Ag paste.

Low sustained voltage $(V_s)$ and high luminous efficiency (lumen/Watts) are required for the enhanced performance of an AC PDP. Both are not realized in the same condition, however, because luminous efficiency decreases when the sustained voltage is lowered in most cases. In this study, the three design factors in the front panel of a PDP, i.e., the thickness and position of the bus electrode and the thickness of the dielectric layer, were chosen to investigate how they affect the sustained voltage and the luminous efficiency, and to find a way to optimize them. Two values were given to each of the three design factors, and experiments were done via full factorial design, i.e., with a total of eight conditions, using a 3-in.diagonal test panel. The changes in the sustained voltage and the luminous characteristics were explained in connection with the discharge characteristics of the PDP cells.

The bus electrode is composed of two layers. One is the black matrix(BM) and silver layer is formed on top of black layer. The BM paste is made by mixing $Co_3O_4$ black powder with photosensitive vehicle and rheological additives. In this work we studied the effect of $Co_3O_4$ black powder and glass frit on the rheological property of photosensitive BM paste. We also examined how the size and content of black powder and glass frit affect the transmittance and reflectance of the BM layer after sintering.
