A flat panel display device including a linked pixel formed of a first pixel electrically connected to a pixel adjacent to the first pixel; a memory storing the location of a panel defect area, a panel defect compensation data for compensating for a brightness difference of the panel defect area, location data describing a location of the linked pixel, charge characteristic compensation data for compensating for a charge characteristic of the linked pixel; and a compensation circuit to modulate the data to be displayed at the panel defect area using at least one of a frame rate control method and a dithering method and to modulate a charge characteristic of a digital video data to be displayed at the linked pixel based on the location data and the panel defect and charge compensation data stored in the memory.
