Abstract:
A method of driving a plasma display panel in a sub-field system including a reset step initializing each cell of a screen at each sub-field, an addressing step selecting cells to be displayed in each of the reset cells, and a sustaining step causing a sustaining discharge with respect to the addressed cells, the method comprising:dividing the screen into a plurality of blocks along scanning lines and applying a reset pulse to only each scanning line of a block to initialize it and simultaneously allowing remaining-immediately the reset blocks to have a blanking interval to which pulses are not applied; sequentially performing an addressing process with respect to the scanning lines in the initialized block to select the cells to be displayed and, at the same time, performing a sustaining discharging at cells, which are selected in a previous sub-field, included in the remaining-immediately reset blocks; allowing the block in which the addressing process has been completed to have a blanking interval to which pulses are not applied and simultaneously applying a reset pulse to only each scanning line of another block to initialize it; performing an addressing process sequentially with respect to the scanning lines in the initialized block to select the cells to be displayed and, at the same time, performing a sustaining discharging at cells, which are selected in a previous sub-field and a current sub-field, included in the remaining-immediately reset blocks; and allowing a sustaining discharge for the blocks in the addressing process previously completed to be continued and simultaneously performing a sustaining discharge for a last block, after an address process for the last block is completed.
