A plasma display device includes an image signal processing circuit having a sequential addressing processing circuit, an alternate addressing processing circuit and an image data selection circuit. The sequential addressing processing circuit includes a sequential addressing array unit for converting an image signal into image data arranged in the order corresponding to a sequential address operation. The alternate addressing processing circuit includes an alternate addressing array unit for converting an image signal into image data arranged in the order corresponding to an alternate address operation. The image data selecting circuit selecting between the sequential and alternate addressing operations based on predicted power consumption.
