How to Use Imaging Colorimeters for Automated Visual Inspection of Displays

White Paper


The use of imaging colorimeter systems and analytical software to assess display brightness and color uniformity, contrast, and to identify defects in displays is well established. A fundamental difference between imaging colorimetry and traditional machine vision is imaging colorimetry's accuracy in matching human visual perception of light and color. This white paper describes how imaging colorimetry can be used in a fully-automated testing system to identify and quantify defects in high-speed, high-volume production environments.

  • Challenges of evaluating displays
  • Measurement components and setup to achieve Automated Visual Inspection (AVI)
  • Using AVI to detect defects in displays
