OPI-220  OPTICAL TEST SYSTEM FOR FLAT PANEL DISPLAY

Build basement for improving uniformity by measuring various optical properties as well BLU of panel display. It is particularly suitable for LED BLU and LED display.


  • Optical property evaluation for rapid and high accuracy FPD
  • Test target: Support up to 62" of sample size for LED BLU, CCFL BLU, LCD module, OLED module, PDP, etc

    Test items : Color gamut, flicker rate, response rate (Optional) including luminance,chromatility, color temperature, Peak wavelength, dominant wavelength, Full width half max, Color rendering index, etc

    Measuring accuracy: wavelength ±3%, chromatility ±0.002

    Measuring method: Takes 4 minutes for 42" 1000 points including 0.1 second for movement and 0.1 seconds for measurement

    Measuring method : Measure using spectrophotometer after recognizing location via semi-automatic sample loading and vision

    Features : For BLU consisting of RGB LED, it analyzes all optical properties of each LED of RGB and white mixed with three colors by only one measurement (Patent)

    - Measure accurate and highly reliable luminance using integrating sphere type input optical system and optical power meter and color correction

    - High speed and low noise by using clean room type linear motor

    - Optimal for evaluating LED BLU and LED display
