Apparatus and method for driving self-emission display panel

Provided are an apparatus and a method for driving a self-emission display panel. A sustain pulse STP controller (620) calculates an automatic power control APC level of image data having an input grayscale and outputs a STP corresponding to the calculated APC level. A sub-field SF controller (640) which applies a dithering method to each SF corresponding to the input grayscale to generate SF data for expressing the input grayscale so as to reduce the number of cells simultaneously emitting light in a SF. A sustain/scan driver (660) generates sustain/scan pulses from the output STP to drive the self-emission display panel (670). An address electrode driver (650) generates an address driving signal corresponding to the input grayscale from the generated SF data to drive the self-emission display panel (670).
