Abstract: The color analyzer (color luminance meter) is widely employed in the brightness and chromaticity measurements of display production lines due to its low cost, simple structure, stable performance, and capability for rapid measurements. However, inherent issues such as spectral mismatch persists in color analyzers.Additionally, the adoption of appropriate calibration methods and the correct selection of the standard displays significantly impact the accuracy of measurement results. This paper evaluates and compares the applicability and accuracy of the single-point calibration method and the four-color matrix calibration method in calibrating display-used color analyzers. The results indicate that the four-color matrix calibration method is more suitable for calibrating display-used color analyzers .
