Abstract:
1. A method of driving a plasma display panel, comprising the steps of: calculating an average picture level of an input picture; mapping data of the input picture to a first sub-fiend group and a second sub-field group; and controlling a time range between the data mapped to the first sub-field group and the data mapped to the second sub-field group according to the calculated average picture levels, wherein the step of controlling the time range between the data mapped to the first sub-field group and the data mapped to the second sub-field group further includes the steps of: if the average picture level is calculated at a first level, wherein the first level is less than a predetermined reference level, controlling a generating time point of the data mapped to the second sub-field group to be at a first starting time point; if the average picture level is calculated at a second level higher than the first level, wherein the second level is less than the predetermined reference level, controlling the generating time point of the data mapped to the second sub-field group to be at a second starting time point later than the first starting time point; and if the average picture level is calculated at a third level higher than the second level, wherein the third level is higher than the predetermined reference level, controlling the generating time point of the data mapped to the second sub-field group to be at a third starting time point earlier than the second starting time point.
