34‐2: Color Correction Model based on Spectral Distribution for solving Metameric Failure in Wide Color Gamut Displays

New technologies for wide color gamut displays like OLED, quantum dot, and micro‐LED have been developed and commercialized. However, these products could face metameric failure so that color measures do not match with perceived color due to the limitation of color matching functions (CMFs) standardized in International Commission on Illumination (CIE) in 1931. Even after new CMFs were suggested to solve these problems in the CIE system, there still remain some more problems. In this study, metameric failure is yet again demonstrated in wide color gamut displays, and a quantitative methodology is proposed for the phenomenon in particular spectral distribution of displays based on experimental results. Furthermore, a color correction method for compensating perceivable differences with measured colorimetric data is developed.
