Abstract
Disclosed is a driving apparatus for a plasma display panel comprising a group of pairs of row electrodes divided into a plurality of sub-blocks, and a driving pulse generator provided in each sub-block for supplying a driving pulse to the associated sub-block, thereby eliminating non-uniform luminance distribution on the display surface due to variations in voltage of pulses supplied to row electrode in the respective sub-blocks. Output terminals of the pulse generators in the respective sub-blocks are connected to each other to make the voltage levels of at least sustain pulses constant.
