Abstract: Provided are an apparatus and a method for driving a self-emission display panel. A sustain pulse (STP) controller 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 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 generates sustain/scan pulses from the output STP to drive the self-emission display panel. An address electrode driver generates an address driving signal corresponding to the input grayscale from the generated SF data to drive the self-emission display panel.
