III  Applications

      3.1 Lv and chromaticity coordinates  measurement of Display panel/LCD

      In a darkroom environment, the display/LCD panel is powered on and warmed up for half an hour. The CI300 is fixed on a mounting fixture, ensuring its optical axis is perpendicular to the display surface, with the probe positioned approximately 30mm from the display surface (or the measurement port is pressed tightly against the screen). The display panel is controlled to show different colors, and the CI300 captures the Lv, chromaticity coordinates, and spectral radiance of the screen at a 1° measurement angle. Based on this data, the display's color gamut and uniformity can be calculated, and functions such as GAMMA/DICOM/color calibration can be performed.

     3.2 LED and solid-state lighting source spectrum, Lv, color temperature, dominant wavelength, and other parameters test

     CI300 luminance colorimeter stand-alone instrument can easily realize Lv, color temperature, dominant wavelength, and other parameters measurement.

     The luminous flux can be measured by integrating sphere. With the help of professional HIQC software, the chromaticity coordinate measurement and classification of LED solid-state light source can be easily realized.

       3.3 A cost-effective testing solution for luminance and color coordinates of displays

       The LCD panel/OLED panel/miniLED panel industry requires high testing accuracy for luminance, and color coordinates, and must be consistent with data from specific brand instruments (standard machines). The testing principle of irradiance/ luminance colorimeter using coated filter plates+CMOS/PD silicon photovoltaic cell detectors usually has CIEXYZ adaptation errors, which can result in slightly lower testing accuracy and data consistency for this type of irradiance/ luminance colorimeter.

       In this case, HCAL software can be used to calibrate this type of irradiance/ luminance colorimeter. If the calibration is reasonable and compared with standard machine test data, the calibrated irradiance/ luminance colorimeter usually has a luminance accuracy of 3% and an average chromaticity coordinate xy error of 0.003.
