APPARATUS AND METHOD FOR DRIVING SELF-EMISSION DISPLAY PANEL

An apparatus and a method for driving an emission display panel are provided to maintain power consumption constantly by reducing the number of cells illuminated at the same time in a sub-field using dithering. An apparatus for driving an emission display panel includes a sustain pulse controller(620), a sub-field controller(640), a sustain/scan driver(660), and an address electrode driver(650). The sustain pulse controller calculates the APC(Automatic Power Control) level of image data having an input gray scale and outputs sustain pulses corresponding to the calculated APC level. The sub-field controller generates sub-field data for displaying the input gray scale using dithering so as to reduce the number of cells illuminated at the same time in a sub-field. The sustain/scan driver drives the emission display panel by generating sustain/scan pulses from the outputted sustain pulses. The address electrode driver drives the emission display panel by generating address driving signals from the generated sub-field data.
