Plasma display apparatus

A plasma display apparatus, comprising plural first and second electrodes that are arranged adjacently by turns and extend in the first direction, plural third electrodes extending in the second direction perpendicular to that of the first direction, and plural fourth electrodes that extend in the first direction and are exposed into the space where a discharge is carried out, wherein, when a first pulses of an alternative current is applied in a sustain action, a pulse is applied to said fourth electrode, provided between said first and second electrodes where said sustain action is carried out, in order to make the initiation of a discharge easier.

A plasma display apparatus, comprising plural first and second electrodes that are arranged adjacently by turns and extend in the first direction, plural third electrodes extending in the second direction perpendicular to that of the first direction, and plural fourth electrodes that extend in the first direction and are exposed into the space where a discharge is carried out, wherein, when a sustain action is carried out, the voltage, which is applied to said fourth electrode provided between said first and the second electrodes where said sustain action is carried out, differs when said first pulse of an alternative current is applied in said sustain action from that thereafter.

A plasma display apparatus, comprising plural first and second electrodes that are arranged adjacently by turns and extend in the first direction and plural third electrodes that extend in the second direction perpendicular to that of the first direction, wherein, after a reset action that sets all the cells to the initial state, an address discharge is selectively caused to occur in a cell for display by applying a voltage selectively to each third electrode, while applying a scanning pulse sequentially to said plural second electrodes to perform an address action that selects a cell for display, an alternative current is applied to said first electrode and said second electrode to perform a sustain action that selectively causes a sustain discharge to occur in the cell selected in said address action, and said reset action, said address action, and said sustain action are carried out repeatedly, wherein, plural fourth electrodes that extend in said first direction and are exposed into said space where said sustain discharge is performed are provided, and said reset action is carried out by applying a pulse with a voltage difference between the adjacent electrodes of said plural fourth electrodes.

A plasma display apparatus, comprising plural first and second electrodes that are arranged adjacently by turns and extend in the first direction, plural third electrodes extending in the second direction perpendicular to that of the first direction, and plural fourth electrodes that extend in the first direction and are exposed into the space where a discharge is carried out, wherein:

• said plural fourth electrodes are provided in space between said first and second electrodes and also outside of said first or second outermost electrode;
• said plural fourth electrodes are classified into two groups in the order of arrangement by turns;
• and two fourth electrode drive circuits that drive said fourth electrodes in each group are independently provided.

A plasma display apparatus, comprising plural first and second electrodes that are arranged adjacently by turns and extend in the first direction, plural third electrodes extending in the second direction perpendicular to that of the first direction, and plural fourth electrodes that extend in the first direction, wherein, a sustain action is carried out between one side of said second electrode and said first electrode said plural fourth electrodes are provided between other side of said second electrode and said first electrode where said sustain action is not carried out, connected commonly, and a voltage is applied by one of said fourth electrode drive circuits to prevent discharge from occurring between said other side of the second electrode and said first electrode in said sustain action.
