The electrodes are then floated to reduce the voltage applied into a discharge space during the discharge to cause a self-quenching of the discharge, thereby precisely controlling wall charges.

摘要： A method for driving a plasma display in which a light emitting state of a plurality of discharge cells of a row electrode is determined in an nth subfield, a line load ratio of the row electrode in the nth subfield is calculated based on the light emitting state, and an output estimation weight of the nth subfield is calculated. Gray levels of the subfields are updated by using the calculated output estimation weight of the nth subfield. Subsequently, the light emitting state of the discharge cells of the row electrode is determined in an (n−1)th subfield by using an initial set weight of the (n−1)th subfield to express the updated gray level, and the line load ratio of the row electrode in the (n−1)th subfield is calculated to determine the output of the (n−1)th subfield. The gray levels for the (n−2)th subfields are updated using the updated output estimation weight.

摘要： In a method of driving a discharge display panel, each subfield may include a first address period, a first display-sustain period, a second address period, and a second display-sustain period. In the first address period, a predetermined wall voltage may be generated in isplay cells selected from the display cells of the first display electrode-line pair group. In the first display-sustain period, display-sustain discharge may occur during a time proportional to a gray scale weight of each of the subfields in the selected display cells of the display cells of the first display electrode-line pair group when the first address period has elapsed. In the second address period, a predetermined wall voltage may be generated in display cells selected from the display cells of the second display electrode-line pair group when the first display-sustain period has elapsed. In the second display-sustain period, display-sustain discharge may occur during a time proportional to a gray scale weight of each of the subfields in the selected display cells of the display cells of the first and second display electrode-line pair groups when the second address period has elapsed.

摘要： A plasma display panel (PDP) and a method for driving the PDP are described. A falling pulse waveform including alternately repeated voltage falling periods and floating periods that have a first mean slope and another falling pulse waveform including alternately repeated voltage falling periods and floating periods that have a second mean slope gentler than the first mean slope may be applied to sustain electrodes. The first and second slopes may be controlled by controlling the floating time or voltage falling range. In accordance with the present invention, it may be possible to apply pulse waveforms having diverse slopes through a simple driving circuit by floating a voltage charged in or discharged from a panel capacitor.
