IS-VA™ FPD View Angle Measurement System

High speed, low cost, view angle performance measurement system for LCDs, PDPs, OLEDs and backlights.

IS-VA™ is the first display metrology instrument ever offered to provide high-speed measurements of color, luminance (brightness) and contrast as a function of view angle for flat panel displays and display components. Based on patented Imaging Sphere™ technology developed jointly with Royal Philips Electronics, the IS-VA™ provides a lower cost alternative to traditional conoscopes and goniometric view angle measurement devices while delivering excellent performance, flexibility, and reliability. The combination of high speed and high resolution makes the IS-VA™ ideal for both R&D projects as well as real-time production QC tasks. It is well suited to a wide range of display types including those based on LCD, PDP, and OLED technologies, as well as backlights.

The turnkey IS-VA™ system consists of a 20" (550 mm) diameter, hemispherical measurement chamber, mated with our PM-1600 Imaging Colorimeter (with a 512x512 or 1024x1024 pixel detector). In addition, IS VA™ is compatible with selected PM Series™ Imaging Colorimeters and Photometers, for those who require a different dynamic range or resolution. The IS-VA™ also is offered with an optional illuminator arm that allows the ambient light scattering properties of a display to be fully characterized. The Illuminator is equipped with a collimated tungsten halogen lamp and can be moved in a light tight slot in the chamber, allowing the illumination angle to be varied at will. The IS-VA™ also comes with a full software suite, which enables manual and fully automated control of all system hardware, as well as complete data analysis and display. Data can be displayed as isometric plots, cross-sectional graphs, radar plots, bit maps and color graphs.
