Fast, Accurate, Low-cost View Angle Performance Measurement Solution for Displays
The Radiant Vision Systems FPD (flat panel display) Conoscope Lens enables high-resolution photopic measurement of the angular distribution of color, luminance, and contrast of displays and display components. Radiant Vision Systems utilizes Fourier optics that map an emitting spot to the camera's image sensor so that each pixel corresponds to a different emission angle. The lens captures a full cone of view angle data in a single measurement to ±70 degrees. This provides quick, accurate results, making the system ideal for both R&D projects and in-line production quality control. The lens is well-suited to a wide range of display types including those based on LCD and OLED technologies, as well as backlights.
High-Resolution Angular Measurement
The FPD Conoscope Lens provides an angular resolution of 0.06 degrees per sensor pixel. Paired with the ProMetric® I Colorimeter (in 16- or 29-megapixel sensor options) or Y Photometer (in 16-, 29-, or 43-megapixel sensor options), the FPD Conoscope Lens has the capability to measure luminance, radiance, angular contrast, CIE chromaticity coordinates, and correlated color temperature (CCT) with a high degree of accuracy at each view angle.
Seamless Evaluation from R&D to Production Lines
The FPD Conoscope Lens solution simultaneously acquires view angle measurements to ±70 degrees with reduced hardware size and complexity compared to typical goniometric measurement systems for R&D applications. A ProMetric camera and lens combination can be purchased for a fraction of the cost of alternative solutions. Because of its speed and compact form factor, the FPD Conoscope Lens solution is also ideally-suited for in-line inspection of displays during production. This capability enables real-time pass/reject operations based on display view angle performance data, eliminating poor-quality components from the line and identifying quality trends before significant materials loss. Using the lens, Radiant Vision Systems cameras can be applied concurrently in R&D and production environments to capture identical measurements of view angle data for seamless evaluation of displays throughout an entire product lifecycle, from initial characterization to quality control.
Typical Applications:
The FPD Conoscope Lens simplifies the process of capturing viewing angle measurements using a single compact camera solution that addresses both off-line and in-line applications:
Viewing angle performance measurement for LCS and OLED flat panel displays
Technology evaluation and characterization in display R&D and quality control
In-line quality control during display manufacturing
