摘要： An operation of reducing a voltage at a scan electrode by as much as a predetermined voltage and floating the scan electrode is repeatedly performed in a reset period of a plasma display panel. When the voltage at the scan electrode is reduced and a discharge is generated, a discharge extinction is generated when the scan electrode is floated, and the voltage at the scan electrode increases. At this time, the voltage increase of the scan electrode is applied and the voltage at the scan electrode is greatly reduced when the voltage at the scan electrode is subsequently reduced.

摘要： The plasma display device includes a plurality of discharge cells, a controller, and a driver. The controller is configured to divide one frame into a plurality of subfields each having a weight value, determine a sustain number allocated to one frame according to a screen load ratio calculated based on video signals inputted for a duration of a frame, allocate the sustain number allocated for one frame to the subfields, and set a minimum sustain number allowed at each screen load ratio and a target sustain number at each screen load ratio. The driver is configured to apply sustain pulses of as many as the sustain number allocated to each subfield to the discharge cells in each subfield. Whenever a first screen load ratio of a current frame is smaller than a second screen load ratio of a previous frame coming right before the current frame, the controller determines a starting point according to a sustain number of the previous frame and the sustain number of the first screen load ratio, and gradually increases the sustain number of the first screen load ratio from the starting point to the target sustain number of the first screen load ratio through subsequent frames.

摘要： In a plasma display device, a second terminal of a first transistor, whose first terminal is connected to an electrode, is connected to a power source for supplying a first voltage. A first driver is adapted to drive the first transistor to change the voltage of the electrode, and a second driver adapted to sustain the voltage of the electrode substantially at a second voltage differing from the first voltage by intercepting a path between the first transistor and the power source when the voltage of the electrode is changed into the second voltage in a first period, and to change the voltage of the electrode substantially back to the first voltage in a second period. In this way, it is possible to supply two or more voltages having a different voltage level by one power source.

摘要： A plasma display panel sustain-discharge circuit. First and second signal lines for supplying first and second voltages and at least one inductor coupled between one end of the panel capacitor and a third voltage are formed. Energy is stored in the inductor through a path formed between the third voltage and the first signal line in a state where a voltage of one end of the panel capacitor is substantially fixed to the first voltage. The voltage of one end of the panel capacitor substantially decreases to the second voltage using resonance current generated between the inductor and the panel capacitor and the stored energy. Energy is stored in the inductor through a path formed between the third voltage and the second line in a state where a voltage of one end of the panel capacitor is substantially fixed to the second voltage. The voltage of one end of the panel capacitor substantially increases to the first voltage using the resonance current generated between the inductor and the panel capacitor and the stored energy.

摘要： An apparatus and method for driving a plasma display panel. In an idle period, a lowest voltage is applied to each circuit of a driving board of a plasma display panel so that a bootstrap capacitor of a switch driving circuit may enter a chargeable state. Therefore, it is possible not only to make the capacity of the bootstrap capacitor of each circuit small, but also to effectively prevent an abnormal discharge or an abnormal operation of each circuit when an abnormal image is inputted.

摘要： A resetting method includes a line discharge step, an erasure step, and an iteration step. The line discharge step is performed during a part of a first pulse width period. During the first pulse width period since a second subfield corresponding to a first XY-electrode line pair starts after a first subfield corresponding to the first XY-electrode line pair ends, a negative voltage of a first level is applied to all X-electrode lines, and simultaneously, a positive voltage of the first level is applied to all Y-electrode lines. In the line discharge step, a negative voltage of a second level higher than the first level is applied to an X-electrode line of the first XY-electrode line pair, and simultaneously, a positive voltage of a third level higher than the first level is applied to a Y-electrode line of the first XY-electrode line pair, thereby provoking discharges in all discharge cells corresponding to the first XY-electrode line pair. In the erasure step, wall charges are erased from all of the discharge cells corresponding to the first XY-electrode line pair. In the iteration step, the line discharge step and the erasure step are repeatedly performed on all XY-electrode line pairs other than the first XY-electrode line pair.
摘要翻译：复位方法包括线路放电步骤，擦除步骤和迭代步骤。行放电步骤在第一脉冲宽度周期的一部分期间执行。在第一脉冲宽度期间，由于与第一XY电极线对对应的第二子场在与第一XY电极线对对应的第一子场结束之后开始，所以第一电平的负电压被施加到所有X电极线并且同时将第一电平的正电压施加到所有Y电极线。在线放电步骤中，将高于第一电平的第二电平的负电压施加到第一XY电极线对的X电极线，同时施加比第一电平高的第三电平的正电压施加到第一XY电极线对的Y电极线，从而在对应于第一XY电极线对的所有放电单元中引发放电。在擦除步骤中，从对应于第一XY电极线对的所有放电单元擦除壁电荷。在迭代步骤中，对除了第一XY电极线对之外的所有XY电极线对重复执行线放电步骤和擦除步骤。
