    • Even in a high-definition panel, an address operation is stabilized by suppressing an abnormal discharge in the address period, and the image display quality is enhanced. For this purpose, the plasma display panel is driven for gradation display in a manner such that a plurality of subfields are set in one field and sustain discharges in a number of times in response to the luminance weight set for each subfield are generated in the sustain period. In this driving method, when the gradation value of one discharge cell of two adjacent discharge cells represented in the one field is a gradation value equal to or larger than a predetermined threshold value, and the gradation value of the other discharge cell is a gradation value at which the discharge cell is lit only in a predetermined subfield, the gradation value of the other discharge cell is changed to a gradation value at which the discharge cell is unlit in all the subfields, or a gradation value at which the discharge cell is lit only in the predetermined subfield and the subfield whose luminance weight is heavy next to that of the predetermined subfield.
    • 即使在高清晰度面板中,通过抑制寻址周期中的异常放电来解决地址操作,并提高图像显示质量。 为此,等离子体显示面板被驱动用于灰度显示,使得在一个场中设置多个子场,并且响应于在每个子场中设置的亮度权重而在维持中产生多次的持续放电 期。 在该驱动方法中,当在一场中表示的两个相邻放电单元的一个放电单元的灰度值为等于或大于预定阈值的灰度值时,另一个放电单元的灰度值为灰度值 其中放电单元仅在预定子场中点亮,其他放电单元的灰度值被改变为在所有子场中放电单元不亮的灰度值或放电单元点亮的灰度值 仅在预定子场和亮度权重比预定子场的亮度重的子场中。
