Abstract
An efficient color compensation method is proposed to reduce the color difference between the camera based inspection system and the colorimeter based inspection system in a plasma display panel production line. The color compensation matrix can be constructed by using the relationship between RGB to XYZ conversion matrices, which are obtained by the RGB primaries and reference white chromaticity coordinates. Experimental results show that the non-contact color inspection system using the proposed color compensation method satisfactorily compensates the chromaticity coordinates acquired by the area color CCD camera to be matched to those measured by the colorimeter for various test color.
