Abstract
Described herein is an AC plasma display panel in which a discharge part is separated from a bus electrode and a partition wall. In this AC plasma display panel, a high emission efficiency can be obtained. Also described is another AC plasma display panel in which a data electrode having a large width part around the surface discharging gap and a narrow width part. The data electrode may further include a medium width part. In this AC plasma display panel, since counter discharge always occurs near a discharge gap of a scanning electrode by employing the data electrode having a specified shape, a high resolution panel with full-color display can be realized.
Claims7
An AC plasma display panel (AC-PDP) comprising:
- first and second glass substrates;
- a plurality of partition walls sandwiched between said first glass substrate and said second glass substrate, said partition walls extending in a column direction to separate a plurality of discharge cells in a row direction;
- a pair of transparent electrodes for extending in said row direction parallel to each other with a discharge gap therebetween in each of said discharge cells to operate surface discharge therebetween;
- a plurality of metallic bus electrodes each disposed on said first glass substrate corresponding to each of said transparent electrodes, each of said transparent electrodes including a discharge part and a coupling part in each of said discharge cells, said coupling part coupling said discharge part to one of said metallic bus electrodes and coupling two of said discharge part disposed in adjacent two of said discharge cells;
- and
- a data electrode disposed on said second glass substrate to extend in each of said discharge cells in said column direction, said data electrode and said discharge part of a corresponding one of said transparent electrodes operating preliminary discharge therebetween,
- wherein said data electrode has a first width adjacent to said metallic bus electrode and a second width adjacent to said discharge part, said first width being smaller than said second width.
