Reducing the CIE colorimetric matching failure on wide color gamut displays

Abstract

Color matching experiments were conducted for 11 pairs of displays, using 7 displays with different spectral characteristics. The color matching results between the LCD display and displays that have a narrowband spectrum, such as a laser projector, QLED, or OLED, demonstrated a significant color difference between two matched colors. The maximum difference was 18.52 ΔE00, which indicates the white color difference between the LCD and laser projector. There was also a clear observer variability of 2.27 ΔE00. The new cone fundamental function derived from 757 metameric pairs showed good performance compared to CIE standard observers reducing the display color mismatching significantly. This function also demonstrated a better performance when evaluating color matching in color chart image.
