Methods for Measuring Display Defects and Mura as Correlated to Human Visual Perception

Human vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production environments. Traditional methods for automated defect detection do not relate directly to human perception....

How to Use Imaging Colorimeters for Automated Visual Inspection of Displays

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...

How to Use Imaging Colorimeters to Improve OLED Display Production Testing Efficiency and Yields

OLEDs (Organic Light-Emitting Diodes) are emerging as the next wave of technology in the flat-panel display market. This is exciting because OLED displays promise improved display appearance for both smartphones and large-format TVs at lower cost and power than other display technologies. As OLED...
