摘要： A plasma display panel device according to the present invention is provided for preventing a generation of unevenness of luminance caused by lowering a discharge voltage applied to cells according to a difference between display load rates. To achieve the above-described objects, the plasma display device according to the present invention employs a phenomenon where voltage drops applied to cells become larger according to a display load rate at a sustain discharge period, as the luminance becomes lower and wall charges accumulated on the cells after the sustain discharge becomes lower as well. In other words, the present invention is characterized in that a prescribed erase pulse and sustain discharge pulse are applied to X and Y electrodes in the sustain discharge period. When the display load rate is lower, a scale of the sustain discharge at each cell is larger and the amount of wall charges at each cell is not lower. Therefore, the plasma display device according to the present invention selectively erases, by applying the prescribed erase pulse, only the cells where a scale of the sustain discharge is large enough to generate sufficient luminance, and compensates the luminance, by generating the sustain discharge due to the sustain discharge pulse thereafter, for the cells where a scale of the sustain discharge is small not enough to generate the sufficient luminance.
摘要翻译：根据本发明的等离子体显示面板装置，用于防止根据显示负载率之差降低施加到单元的放电电压而引起的亮度不均匀。为了实现上述目的，根据本发明的等离子体显示装置采用根据显示负载率在维持放电时段对电池施加电压降变得更大的现象，因为亮度变低，壁电荷累积在维持放电后的电池也变小。换句话说，本发明的特征在于，在维持放电期间，向X，Y电极施加规定的擦除脉冲和维持放电脉冲。当显示负载率较低时，每个单元处的维持放电的比例较大，并且每个单元的壁电荷量不低。因此，根据本发明的等离子体显示装置通过施加规定的擦除脉冲仅选择性地擦除维持放电的规模足够大以产生足够亮度的电池，并通过产生维持放电来补偿亮度对于维持放电脉冲之后，对于维持放电的刻度小的单元，不足以产生足够的亮度。

The plasma display comprises: a plasma display panel in which first, second, and third electrodes are arranged alternately parallel to one another on a first substrate, and fourth electrodes are arranged orthogonally to the first electrodes on the first substrate or a second substrate; a first electrode selection driver for selectively driving the first electrodes; a second electrode driver for driving the second electrodes, and a third electrode driver for driving the third electrodes. First display cells are formed at intersections between the first electrodes and second electrodes and the fourth electrodes, and second display cells are formed at intersections between the first electrodes and third electrodes and the fourth electrodes. The first display cells and second display cells are alternately and repeatedly allowed to glow for display for the purpose of achieving interlacing display. In the plasma display, during a reset period, the second electrode driver and third electrode driver apply voltages to the second and third electrodes respectively so that priming discharge can be induced in third cells. The third cells for priming are formed with the second electrodes and third electrodes.
