Patent ID: 7339556

Claim:
A method for driving a discharge display panel performing a gray scale display operation of a unit frame with a time-sharing driving scheme, where the panel comprises scan electrodes and sustain electrodes alternately arranged in rows on a first substrate and address electrodes arranged on a second substrate in a direction substantially orthogonal to the scan electrodes and the sustain electrodes, the method comprising: dividing the unit frame into at least one first type sub-field, one second type sub-field, and at least two sub-fields having equally weighted display-sustain periods, the at least two subfields being different subfields than the first type sub-field and the second type sub-field; grouping the scan electrodes into at least a first scan electrode group and a second scan electrode group; in the first type sub-field, addressing the first scan electrode group; sustain discharging the first scan electrode group; addressing the second scan electrode group; and sustain discharging the first scan electrode group and the second scan electrode group; and in the second type sub-field, addressing the second scan electrode group; sustain discharging the second scan electrode group; addressing the first scan electrode group; and sustain discharging the first scan electrode group and the second scan electrode group.
