BOSTON, July 5, 2012 — Radiant Zemax has launched its TrueTest system for automated optical inspection. It combines proprietary imaging colorimeters, a software-based test controller and an extensive set of standard test functions to provide high-speed, high-volume optical testing for flat panel display production. It is used in display final assembly, panel subassembly, touch screens, backlight units and cover glass testing.
At the core of the system is test control software that allows users to select tests, set pass/fail parameters and criteria, define test patterns, and order the tests in any sequence. Once the setup is complete, ongoing operation in a production environment can be fully automated. The software controls data acquisition via the imaging colorimeter, controls the video pattern generator, and interfaces to the production control system.
The system has more than 25 quality and defect detection tests, such as ANSI uniformity, checkerboard contrast, pixel defects, and gradients; and mura detection tests, such as color mura, edge mura and LED mura. It also can compute “just noticeable difference” values with the company’s integrated TrueMura module. The TrueTest system works with any of the company’s ProMetric imaging colorimeters, which are available in multiple resolutions and sensitivities.
