Abstract

A method of driving a surface discharge plasma display panel has a reset step of applying a pulse of a first voltage to paired first and second electrodes, a write step of applying a pulse of a second voltage to second and third electrodes corresponding to cells to be turned ON, and a sustain discharge step of applying an AC pulse of a fourth voltage to the paired first and second electrodes. The pulse of the first voltage is so set that it is higher than a first discharge start voltage, a third voltage caused by the discharge is higher than the first discharge start voltage, and the first, second, and third electrodes have the same potential after the application of the pulse of the first voltage. Therefore, an address discharge of the surface discharge plasma display panel can be caused by a wide range of voltages, and display quality of the panel can be improved.

Dependent claims

A method of driving a surface discharge plasma display panel having a first substrate and a second substrate spaced apart and facing each other, and first electrodes, second electrodes, and third electrodes arranged between said first and second substrates, said first electrodes being arranged in parallel with said second electrodes, said third electrodes being arranged orthogonal to said first electrodes and said second electrodes, said first electrodes and said second electrodes intersecting with said third electrodes to form respective intersections which each define a corresponding cell that can be selectively turned ON and OFF, a discharge being produced in a respective cell when a first discharge start voltage is applied to the respective cell, wherein said method comprises:

a reset step of applying a pulse of a first voltage to the respective cell, and thereby cause an accumulation of wall charges in the respective cell, the pulse of the first voltage being higher than the first discharge start voltage, a third voltage being caused by the wall charges and being higher than the first discharge start voltage, and said first, second and third electrodes have the same potential after the application of the pulse of the first voltage;
a write step of applying a pulse of a second voltage to said second and third electrodes to select cells to be turned ON;
and
a sustain discharge step of applying an AC pulse of a fourth voltage to said first and second electrodes.
