Abstract: | A macroscopic cell and three-dimensional fluid model have been used
to investigate the discharge characteristics in ac plasma display
panel cells of electrode-shaping configurations. Four kinds of
non-standard geometries (i.e. $D$-, ${\it\del}$-, $W$- and $U$-shape
electrodes) have been considered. The characteristics of the
discharge current, the operating voltage and the discharge
efficiency of different configurations have been discussed. It is
found that the discharge efficiency can be improved by about
10\%--30\% compared with the standard geometry, while the operating
voltage increases slightly in the non-standard geometries. There is
a trade-off between improving the discharge efficiency and lowering
the sustaining voltage in design of plasma display cells by
electrode shaping. |
