✦ Synopsis
In a surface discharge AC-plasma display panel (PDP), the efficiencies of brightness and intensity are worsened with a decrease of electrode width. On the other hand, when the electrode width is increased, the gap between the adjacent cells decreases, causing an increase in the frequency of misdischarge. In order to improve the intensity efficiency, it is important to find the minimum value of the cell-to-cell gap. It was found that the static characteristic of the narrow cell-to-cell gap provides information on the unstable memory operation region which characterizes an AC-PDP. The unstable memory operation region depends on the frequency and discharge time lag. It was also found that when the cell surface intensity profile and leakage current between lines were measured, discharge takes place between adjacent cells in the unstable memory operation region. These phenomena were discussed using the relationship between the discharge time lag difference between the electrode-to-electrode gap and adjacent cell gap and the discharge sustain time.
It was found that even when the gap between the adjacent cells is narrow, unstable memory operation can be controlled, indicating that a high-definition surface discharge AC-PDP can be fabricated.
