Abstract
Disclosed herein is a method and apparatus for driving a plasma display panel, which improves contrast characteristics and preventing a low discharge making a cell non-luminous at a specific gray scale. The method for driving a plasma display panel includes the steps of initializing a cell by supplying a first write voltage and an erase voltage to a scanning electrode during a reset interval of the n-th sub-field; initializing the cell by supplying the erase voltage and a second write voltage which is higher than a sustaining voltage and lower than the first write voltage to the scanning electrode during a reset interval of the (n+1)-th sub-field; selecting the cell by supplying the scanning voltage to the scanning electrode and supplying a data voltage to an address electrode during an address interval of each of the n-th and (n+1)-th sub-fields; and alternatively supplying the sustaining voltage to the scanning and sustaining electrodes during a sustaining interval of each of the n-th and (n+1 )-th sub-fields.
