    • In a PDP unit, a display frame for one screen comprises a plurality of sub-frames, the luminance of each of which is determined by a sustaining pulse number. A length of one frame is calculated from the length of one cycle of a vertical synchronization signal and a sub-frame condition determination circuit determines, from the length of one frame, the number of sub-frames, the luminance of each sub-frame and a total sustaining pulse number. A load factor is calculated from an external input signal. A further circuit determines a maximum display luminance from consumed power and calculates a luminance factor, and yet a further circuit corrects the luminance drop due to a load from the total sustaining pulse number, the luminance ratio and the load factor for the respective sub-frame and calculates sustaining pulse numbers for the respective sub-frames. Thereby, the sustaining pulse numbers of the respective sub-frames are determined through calculations using the total sustaining pulse number, the luminance ratio, the load factor and the consumed power rather than using a luminance table, simplifying construction of the PDP unit while performing more accurate calculations and thereby improving display quality and providing a stable display without flickering.
    • 在PDP单元中,一个屏幕的显示帧包括多个子帧,每个子帧的亮度由维持脉冲数确定。 从垂直同步信号的一个周期的长度计算一帧的长度,并且子帧条件确定电路从一帧的长度确定子帧的数量,每个子帧的亮度和 总维持脉冲数。 负载系数由外部输入信号计算。 另外的电路确定从消耗的功率的最大显示亮度并计算亮度因子,并且还有一个电路校正由相对于子帧的总维持脉冲数,亮度比和负载因子的负载引起的亮度下降 并计算各个子帧的维持脉冲数。 因此,通过使用总维持脉冲数,亮度比,负载因子和消耗功率的计算来确定各个子帧的维持脉冲数,而不是使用亮度表,从而简化了PDP单元的构造,同时执行更多 精确的计算,从而提高显示质量,并提供稳定的显示而不闪烁。

    • A plasma display device has a plasma display panel (PDP), a first driver circuit, and a first flexible cable. The PDP has a first plate on which a plurality of first and second electrodes extending in a first direction are provided and a second plate facing the first plate via a discharge space. Here, the first driver circuit is a circuit which applies a voltage to the first electrodes. Further, the first flexible cable has one end coupled to the first electrodes in a circumference part of the plasma display panel, and has the other end coupled to the first driver circuit inside a circumference of the plasma display panel without folding back the first flexible cable. Consequently, disconnection between the PDP and the driver circuit can be prevented, and reliability of the PDP device can be improved.
    • 等离子体显示装置具有等离子体显示面板(PDP),第一驱动电路和第一柔性电缆。 PDP具有第一板,其上设置有沿第一方向延伸的多个第一和第二电极以及经由放电空间面向第一板的第二板。 这里,第一驱动电路是向第一电极施加电压的电路。 此外,第一柔性电缆的一端在等离子体显示面板的圆周部分中耦合到第一电极,并且另一端在等离子体显示面板的圆周内连接到第一驱动电路,而不折叠第一柔性电缆 。 因此,可以防止PDP和驱动电路之间的断开,并且可以提高PDP装置的可靠性。

    • According to the present invention, a plasma display apparatus, which represents the luminance of one frame in accordance with a combination of plural sub-frames having luminance levels corresponding to a plurality of weighted values, additionally includes a sub-frame having a luminance level lower than the minimum gray scale level of luminance which can be represented by the number of bits in the input video data. Such plasma display apparatus turns on a desired combination of the sub-frames so as to increase the resolution of the luminance without increasing the conventional number of gray scale levels included in the input video data. In a preferred embodiment, especially when the added smaller luminance sub-frame is included in a combination of sub-frames for a low luminance area, the resolution of the gray scale of the low luminance area can be increased, and the representation of gray scale can be enhanced in a low luminance area to which the sight of a person is more sensitive.
