摘要： The present invention relates to a plasma display panel and, more particularly, to an apparatus and a method of driving a plasma display panel. According to the present invention, an apparatus for driving a plasma display panel includes a line buffer unit synchronizing data inputted from outside with a horizontal synchronization signal to store per horizontal line, at least one comparison unit comparing loads included in horizontal lines stored in the line buffer unit, and a data converting unit correcting the data to be supplied to the horizontal lines using a load difference resulting from a comparison by the at least one comparison unit. According to the present invention, a method of driving a plasma display panel includes the steps of detecting loads included in externally inputted data to be supplied to at least two adjacent horizontal lines and correcting the data to be supplied to each of the at least two adjacent horizontal lines according to a load difference between the at least two adjacent horizontal lines. Accordingly, the loads included in the previous and current lines are computed to correct the data to be supplied to the lines according to the load difference between the respective lines, respectively. Therefore, the present invention enables to correct the brightness difference between the horizontal lines and to prevent power dispersion of the heavily-loaded horizontal line.

摘要： The present invention relates to a plasma display apparatus and driving method of the same. Since wall charges are remained without performing an additional erasing discharge after the sustain period is terminated and before the initiation of the reset period, the set up discharge can be generated with a small voltage during the reset period to obtain the margin of the driving voltage. In particular, since the highest voltage of the reset period during other subfields is lower than the highest voltage of the reset period of a subfield implementing a low gray scale, with inducing the half discharge before the set up discharge in other subfields, the set up discharge can be generated with a low voltage to improve the contrast due to the luminous output reduction.
摘要翻译： 等离子体显示装置及其驱动方法技术领域本发明涉及等离子体显示装置及其驱动方法。 由于在维持期间结束后和复位期间开始之前保持壁电荷而不执行附加的擦除放电，所以可以在复位期间以小的电压产生放电放电，以获得驱动电压的余量。 特别地，由于其他子场中的复位期间的最高电压低于实施低灰度级的子场的复位期间的最高电压，因此在其他子场的设定放电之前引起半放电， 可以以低电压产生放电，以便由于发光输出减少而改善对比度。

摘要： A piping structure of an air conditioner causes a looped main piping connected to a compressor of an outdoor unit of the air conditioner to be branched into two or more branch pipings within a predetermined interval of the main piping and cause the branch pipings to be jointed at an arbitrary location. According to the piping structure, it is possible to reduce a vibration by an interference phenomenon, which is generated when either a refrigerant pulsation or a periodic vibration of the compressor is divided and then combined.

摘要： A plasma display panel apparatus and a method of driving the same are disclosed. Right after power is supplied to a panel, driving waveforms are applied such that an address discharge and a sustain discharge cannot occur during at least one or more sub-fields. Accordingly, time for a source capacitor of an energy recovery unit provided in a scan driver and a sustain driver to be charged with a voltage can be secured and a preliminary time for an element of the driving circuit and the discharge cell to be activated can be secured, to thereby prevent damage of the element.
