Abstract:
A method of energizing a plasma display panel having a plurality of scanning electrodes arranged as rows and a plurality of data electrodes arranged as columns, comprising the steps of:applying a scanning pulse voltage to the scanning electrodes; applying a data pulse voltage to the data electrodes in synchronism with said scanning pulse voltage for controlling turning-on/off of displayed data; and thereafter, applying a sustaining pulse voltage of a waveform having repetitive units, each of said units comprising a preceding high potential difference of a short duration and a subsequent low potential difference of a long duration, alternately to two electrodes selected from the scanning electrodes, the data electrodes, and common electrodes arranged as rows independently of the scanning electrodes, for thereby keeping a sustaining discharge only in cell where the displayed data is turned on, wherein said low potential difference is not zero.
