Display metrology is the scientific quantification of values of light that enable evaluation of the visual qualities of a display, from brightness to color to contrast, according to how they are perceived by a standard human observer. Metrology is accomplished using a range of technologies—spectrometers, imaging systems, specialized lenses, analysis software, etc. While most of these measurement systems are well suited to lab and R&D environments, production-level testing of displays has a unique set of requirements. In-line, automated optical inspection (AOI) requires equipment that supports demanding throughput needs while ensuring quality according to standards, specifications, and user expectations.
In this presentation from Radiant Vision Systems, Sales Director Matt Scholz discusses how production demands and metrology system limitations have led to the common misconception that scientific evaluation of displays cannot be applied effectively for in-line quality control. This webinar will review the fundamentals of display metrology and introduce technologies that bridge the gap between scientific measurement and high-throughput AOI.

What will attendees learn:

• Display test challenges for current and future production
• Scientific display metrology: Measuring light to determine visual quality
• Characteristics of the ideal AOI system
• Misconceptions about applying metrology for production AOI
• Examples of advanced metrology systems with advantages for in-line inspection
