METHOD OF CHROMATICITY ADJUSTMENT OF DISPLAY DEVICE |
摘要 |
Provided is a method of chromaticity adjustment of a display device including a drive circuit for generating a gray-scale signal corresponding to a video signal input from an external portion and supplying the gray-scale signal to a plurality of pixels, the method including: measuring chromaticity coordinates of an image displayed on the display device; determining whether the measured chromaticity coordinates are chromaticity coordinates within a first region that does not need a chromaticity correction or chromaticity coordinates within a second region that needs the chromaticity correction; determining, if the measured chromaticity coordinates are the chromaticity coordinates within the second region, which of a plurality of correction regions obtained by dividing the second region the chromaticity coordinates fall within; correcting the gray-scale signal corresponding to the video signal by using a chromaticity correcting portion corresponding to the determined one of the plurality of correction regions; and performing corrected image display. |
