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（中）：
等离子体显示面板技术领域本发明涉及等离子体显示面板，更具体地，涉及一种驱动等离子体显示面板的装置和方法。 根据本发明，用于驱动等离子体显示面板的装置包括行数据缓冲单元，其将从外部输入的数据与水平同步信号同步以每条水平行存储;至少一个比较单元，比较包含在存储在该行中的水平行中的负载 缓冲单元和数据转换单元，使用由所述至少一个比较单元进行的比较得到的负载差来校正要提供给水平线的数据。 根据本发明，驱动等离子体显示面板的方法包括以下步骤：检测包括在外部输入的数据中的负载，以提供给至少两个相邻的水平线，并校正要提供给至少两个相邻的每一个的数据 根据所述至少两个相邻水平线之间的负载差异的水平线。 因此，计算包括在前一行和当前行中的负载，以分别根据各行之间的负载差来校正要提供给行的数据。 因此，本发明能够校正水平线之间的亮度差，并且防止重负载水平线的功率分散。
