Test Bench for Display Optical Measurement

Fully automated optical display test system

The display test system has been developed to perform fully automated optical display measurments, as for example, required in the automotive industry. Due to the high degree of automation, the system can be easely operated without a detailed knowledge of optical measurment. The test results are shown in an easy to read measurement report (MS Excel), including customer specific assessment of each measurement data.

Essentially, the system consists of four components

  • Light density measuring chamber with motorized positionable measuring camera in three axes relative to the display
  • Video Source to control the display
  • Individually adaptable to customer application GUI
  • Camera measurement (Video Photometer) with 5 mpx [adjusted to the CIE color perception functions of the 2° standard observer (CIE 1931)

Facts

  • Measurement data: luminance and chromaticity, Gamma, dimming, ISO contrast, BlackMura, contrast, homogeneity, Color and luminance drift over time
  • Measurement parameters: luminance L (cd/m²); color spaces: Lxy, HSV, RGB, XYZ, sRGB, L*a*b, Luv
  • Measuring range: (intergration times): 100μs … 15s
  • Measuring camera: 2448 x 2050 Pixel, ( 2/3"; 14 Bit digital)
  • Camera positioning accuracy +-0,1mm, each in x, y and z- axis
  • Displays up to a size of 450 mm x 2550 mm
  • Measurement report in MS Excel Format with accessment
