Abstract:
1. A flat panel display device, comprising: a display panel having a link pixel including a defective pixel electrical connected to an adjacent normal pixel, wherein the normal pixel adjacent to the defective pixel is a pixel of the same color as the defective pixel; a memory to store: first location data describing the location of a panel defect area of the display panel having a brightness difference in comparison to a normal area of the display driven with the same data as the panel defect area; panel defect compensation data to compensate for the brightness difference of the panel defect area; second location data describing a location of the link pixel; and charge characteristic compensation data to compensating for a charge characteristic of the link pixel; a first compensating part to modulate data to be supplied to the panel defect area using a frame rate control dithering method, the first location data and the panel defect compensation data; and a second compensating part modulate a charge characteristic of a digital video data to be displayed at the link pixel among data output from the first compensating part using the charge characteristic compensation data, wherein the first compensating part is to temporally sub-divide panel defect compensation data over a unit of a frames, to spatially sub-divide panel defect compensation data over a number of adjacent pixels, and to increase or decrease data to be displayed at the panel defect area by the spatially and the temporally divided panel defect compensation data.
