<P>PROBLEM TO BE SOLVED: To provide a display device capable of correcting variance in color tone appearing by panels. <P>SOLUTION: The display device includes a color correcting circuit 5 which corrects colors of an externally input RGB video signal and then outputs the RGB video signal to a panel 1. The color correcting circuit 5 previously measures a saturation color and white characteristic of the panel in the form of XYZ chromaticity and finds a first conversion matrix for converting RGB chromaticity of the input RGB video signal into XYZ chromaticity, based upon measurement results. Further, the color correcting circuit 5 finds a second conversion matrix for converting XYZ chromaticity of a saturation color previously set depending upon specifications of the panel into RGB chromaticity, and then converts the input RGB video signal into an output RGB video signal by using those first and second conversion matrixes to correct variances in saturation color and white appearing by panels according to specifications of the panels. <P>COPYRIGHT: (C)2007,JPO&INPIT |
