摘要： 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.

摘要： 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.

摘要： 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.
