摘要： A display device for displaying pictures by sequentially performing an address period and a sustain period. The panel pixels are arranged into groups, and an address period and a sustain period are sequentially performed on the pixels of individual groups. While an address period is being performed on the pixels of a group, the pixels of other groups are idle. While a sustain period is being performed on the pixels of the group subsequent to the address period, a sustain period is selectively performed on the pixels of other groups that have already undergone an address period. Accordingly, a sustain discharge operation is performed within a short time after an address operation is performed on the pixels, so that a stable sustain discharge occurs even though narrow scan pulses and address pulses may be applied during the address operation. Also, the time required to address all pixels is reduced.

摘要： Disclosed is a reset waveform of a plasma display panel. A rising or falling voltage is applied rapidly enough to cause an intense discharge in a reset interval. 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： 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.

摘要： A PDP driving method. A falling ramp voltage is applied to a scan electrode so as to reset a state of wall charges of a discharge cell during a reset period. In this instance, a sustain electrode is maintained at a high voltage during an initial period for applying the falling ramp voltage, and the voltage at the sustain electrode is reduced to a normal voltage at a latter part of the period for applying the falling ramp voltage. Accordingly, the voltage applied to an address electrode is reduced in an address period since an erased amount of the wall charges of the address electrode is reduced during the reset period.

摘要翻译： PDP驱动方法。 向扫描电极施加下降的斜坡电压，以便在复位期间复位放电单元的壁电荷的状态。 在这种情况下，在施加下降斜坡电压的初始期间，维持电极保持在高电压，在施加下降斜坡电压的期间的后期将维持电极的电压降低到正常电压 。 因此，由于在复位期间地址电极的壁电荷的擦除量减少，所以施加到寻址电极的电压在寻址期间减少。
