  • A highly stable white field instrument for LED-backlit liquid crystal displays was developed. It has functions of luminance monitoring, luminance calibration and luminance compensation. This instrument can be used for laboratory and field calibration of color analyzers and periodic verification of luminance colorimeters. Its metrological characteristics, including luminance, chromaticity, spectrum, stability and uniformity, were studied. The uncertainty in calibration of color analyzers with the white field instrument was evaluated.
