Abstract:
A plasma address display apparatus, comprising:a plasma cell comprising a plurality of scanning electrodes disposed in rows, discharge channels between rows, and discharge gas in the discharge channels; a display cell comprising a plurality of signal electrodes disposed in columns coupled to the plasma cell; a scanning circuit for successively applying selection pulses to said scanning electrodes; and a signal circuit for supplying image data to said signal electrodes; wherein the selection pulses create a first scanning line and a second scanning line in a selected discharge channel; wherein the selected discharge channel comprises a first scanning electrode supporting a first barrier, a second scanning electrode supporting a second barrier, and a central scanning electrode between the first scanning electrode and the second scanning electrode, and wherein the first scanning line is created between the first scanning electrode and the central scanning electrode, and the second scanning line is created between the central scanning electrode and the second scanning electrode; and wherein the selection pulses include a first selection pulse applied to the central scanning electrode that is operative to cause discharge in the selected discharge channel for both the first and second scanning lines in the selected discharge channel, and a second selection pulse applied to the second scanning electrode that is operative to cause discharge in a portion of the selected discharge channel corresponding to the second scanning line without causing discharge in the selected discharge channel for the first scanning line.
