摘要： Disclosed herein is an apparatus for driving a plasma display panel in which a gray scale inversion phenomenon can be prevented. According to the present invention, the apparatus for driving the PDP includes an error diffusion unit for diffusing error of data received from an inverse gamma correction unit, a gray scale inversion check unit connected to the inverse gamma correction unit, for checking whether a gray scale value of the data received from the inverse gamma correction unit is a gray scale value where a gray scale inversion phenomenon is generated, and generating a 1-bit control signal according to the check result, an adder disposed between the error diffusion unit and the gray scale inversion check unit, for adding the 1-bit control signal to lower bits of the data received from the error diffusion unit, and a dithering unit for performing dithering by using the lower bits received from the adder. Therefore, when dithering is performed on data where gray scale inversion is generated, a gray scale value can be improved by adding 1 to lowest bits of the data. It is thus possible to prevent the gray scale inversion phenomenon.
