A plasma address display apparatus is composed of a flat panel, a scanning circuit, and a signal circuit. The flat panel has a layered structure wherein a plasma cell having scanning electrodes disposed in rows and a display cell having signal electrodes disposed in columns are placed one on the other. The scanning circuit successively applies a selection pulse to the scanning electrodes to effect scanning of the display cell. The signal circuit supplies image data to the signal electrodes in synchronism with the scanning to write the image data for individual scanning lines. The plasma cell has discharge channels formed in rows such that they are isolated from each other, and a plurality of scanning electrodes are allocated to each of the discharge channels. The scanning circuit successively applies a selection pulse to the scanning electrodes allocated to a discharge channel to cause discharge to occur so that, for example, at least two scanning lines are formed in each one discharge channel. Since at least two scanning lines are formed in each one discharge channel, the plasma address display apparatus can achieve realization in numerical aperture and also in resolution. |
