Abstract
A method and apparatus for reducing flicker when displaying pictures on a plasma display panel, based on an input phase alternation line (PAL) video signal of 50 Hz. Video signal data include successive first and second sub-field groups. When the number of sub-fields in the first sub-field group is more than that of sub-fields in the second sub-field group, the start or end points of the first and second sub-field groups are fixed, based on whether the video signal has a load ratio higher than a threshold value. When the number of sub-fields in the first sub-field group is less than that of sub-fields in the second sub-field group, the start or end points of the first and second sub-field groups are fixed, based on whether the video signal has a load ratio higher than a threshold value.
