We present a measurement uncertainty evaluation for emission color and luminance of displays. The calibration procedures and the measurement uncertainties of a CCD-based spectroradiometer and a filter-type luminance meter are discussed. As evaluation examples, a Commission Internationale de l' Eclairage illuminant A, a liquid-crystal display with a light-emitting diode backlight, and a liquid-crystal display with a cold-cathode fluorescent lamp backlight are evaluated. The uncertainties in Commission Internationale de l' Eclairage 1931 (x,y) chromaticity coordinates are determined to be in a range from 0.0020 to 0.0050 (k=2). The uncertainties in luminance are obtained from 4.8% to 8.5% by using the spectroradiometer, while the filter-type luminance meter shows the uncertainties from 1.1% to 1.6% (k=2).
