摘要： A method of driving a plasma display panel which is capable of increasing the number of intermediate luminance levels which can be represented in units of pixel cells while suppressing spurious borders. Each frame display period includes a first sub-field group which has a plurality of sub-fields arranged in succession such that the values of luminance weighting coefficients assigned thereto advance in a form of geometric series with a common ratio being set to two, and a second sub-field group which includes a sub-field assigned the largest luminance weighting coefficient and has a plurality of sub-fields arranged in succession such that the value of luminance weighting coefficients assigned thereto advance in a form of arithmetic series. A sub-field assigned the largest luminance weighting coefficient is placed at a position other than the head and tail of the frame display period.
