Abstract:
1. A flat panel display device, comprising: a display panel; a memory operable to store a location information and a compensation value for a panel defect location on the display panel; a first converter operable to calculate a brightness signal and a color difference signal from an inputted video signal to be displayed in the display panel and operable to expand a number of data bits of the brightness signal to generate an expanded brightness signal; a compensating part operable to generate a compensated brightness signal by compensating the expanded brightness signal of the video signal, to be displayed in the panel defect location, by the compensation value in reference to the memory; a second converter operable to calculate a compensated video signal from the color difference signal and the compensated brightness signal, wherein the compensated video signal has the same number of bits as the inputted video signal; and a drive circuit operable to drive the display panel by use of the compensated video signal and an uncompensated video signal.
