摘要： A disclosed plasma display apparatus and a plasma display panel driving method provide improved luminance while preventing decrease in resolution. In the plasma display apparatus, which is adapted to the display of an interlace signal, the maximum number of sustain pulses associated with the emission of light that can be made in one field is calculated, based on the vertical synchronization signal frequency of the input signal. A display load factor of the input signal in the one field is calculated and, based on the calculated display load factor, a target number of sustain pulses in the one field is determined. Based on a relationship between the target number of sustain pulses and the maximum number of sustain pulses, an emission luminance ratio of a sub-display line to a main-display line in the one field is determined.

摘要： A display apparatus, which displays a color image by controlling the number of emissions or the intensity thereof in accordance with primary color video signals input thereto, has a detection portion and a white balance correction portion. The detection portion is used to detect the number of emissions or the intensity, and the white balance correction portion is used to correct white balance by adjusting the amplitudes of the primary color video signals in accordance with the detected number of emissions or the detected intensity. Therefore, correct white balance can be maintained regardless of the number of emissions or the intensity of emission.

摘要： A method and an apparatus for correcting a color reproduction distortion for each of all the hues are provided. A predetermined demodulating axis of three demodulating axes SR, SG and SB for the three primary colors R, G and B, herein, the R-Y demodulating axis SR is formed by combining the two demodulating axes SR2 and SR3. The demodulating axis SR2 provides a different demodulating gain from the standard demodulating axis. The demodulating axis SR3 provides a different demodulating angle from the standard demodulating axis in addition to the different demodulating gain. Then, a smaller one of the signals demodulated by the demodulating axes SR2 and SR3 is selected. It means that the signal changing along the vector orbit E1 indicated by oblique lines is made to be a color difference signal R-Y. By this function, from the signals demodulated about the demodulating axes SR2 and SR3, the portions with no color reproduction distortion are extracted and synthesized so that no color reproduction distortion takes place with respect to all the hues.
