Method of driving display panel

A method for driving a display panel is provided to make clear gradation expression and remove an afterimage generated at an image having continuous frames through erasure, program, and emission mechanism. Respective pixels are set to a program state or an erasure state by applying a data signal corresponding to a program voltage or an erasure voltage to pixels. Pixels emit the light by supplying a data signal corresponding to a read voltage to all pixels entering the program state or the erasure state.
