Choosing a Measurement System for LED Sources, Luminaires, and Displays

LEDs remain a pivotal light-emitting element in a range of lighting products and displays. For manufacturers of these devices, it is important to evaluate the performance of LEDs and LED-based systems in objective and meaningful ways. The purpose of the measurement—to inform development, to characterize or...

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 colorimeters and associated analytical software for automated visual inspection (AVI) of displays is well established. A fundamental difference between imaging colorimetry and traditional machine vision is imaging colorimetry’s accuracy when it comes to matching human visual perception of...
