Abstract
A plasma display panel includes display cells disposed in matrix at cross points of a plurality of common electrodes and a plurality of data electrodes. In each of the display cells, data writing discharge and sustaining discharge are performed to emit light. Brightness is controlled by applying a sustaining pulse having a frequency higher than μiV/(πd2) between the sustaining electrodes, where μi is an ion mobility of the discharge gas filled in the display cell, V is a maximum value of the applied voltage, and d is a distance between the sustaining electrodes performing the sustaining discharge.
Claims6
A method for driving a plasma display panel (PDP) having a plurality of display cells arranged in a matrix and each receiving therein discharge gas, first and second sustaining electrodes extending in a first direction of said matrix of display cells, and a data electrode extending in a second direction perpendicular to said first direction, said method comprising the steps of selectively applying a writing pulse between said first sustaining electrode and said data electrode, and applying a sustaining pulse train between said first sustaining electrode and said second sustaining electrode, said sustaining pulse train having a repetitive frequency f defined as follows;
- f≧μiV/(πd2)
- wherein μi, V and d are an ion mobility of said discharge gas, a peak voltage of said sustaining pulse train and a distance between said first sustaining electrode and said second sustaining electrode, respectively.
