Abstract:
A method of driving an AC-type plasma display panel,said AC-type plasma display panel comprising: a first substrate including a plurality of sustain discharge electrodes extending in parallel with one another, between adjacent two of which each of a plurality of scanning lines is defined, each of said sustain discharge electrodes is shared by adjacent two of said scanning lines, and a dielectric layer covering said sustain discharge electrodes, said dielectric layer having a main surface on which surface discharges are generated, said surface discharges illuminating discharge cells belonging to each of said scanning lines; a second substrate provided on a side of said main surface of said dielectric layer face to face with said first substrate, said second substrate including a plurality of address electrodes provided in a direction to intersect said sustain discharge electrodes, said address electrodes extending in parallel with one another; and a plurality of barrier ribs provided between said first and second substrates, said surface discharges of said discharge cells belonging to each of said scanning lines being substantially separated by said adjacent two scanning lines, wherein one screen is divided into a plurality of sub-fields, each of said plurality of sub-fields including an addressing period for performing sequentially a selection of said scanning lines by applying scanning-line selection voltages of different values to adjacent two of said sustain discharge electrodes to scan said scanning lines and performing an addressing operation in synchronization with said selection of said scanning lines, in which voltages according to ON/OFF states of image data of a selected scanning line are applied to said address electrodes, to store electric charges in said discharge cell belonging to said address electrode to which said voltage corresponding to said ON state is applied; and a sustain period for performing a discharge sustain operation in which a sustain voltage is applied to said sustain discharge electrodes, to generate said surface discharge in said discharge cell in which said electric charges are stored, and wherein said plurality of scanning lines are divided into a plurality of groups such that adjacent two scanning lines which share a sustain discharge electrode to which a relatively negative scanning-line selection voltage is applied at the time of said selection of said scanning lines belong to different groups, and said addressing operation is performed per said group at respective times in said addressing period, and said discharge sustain operation is performed on all of said discharge cells belonging to said adjacent two scanning lines in said sustain period.
