PM-FPMS™ Flat Panel Measurement System

Comprehensive measurement system for flat panel displays and components.

PM-FPMS™ performs brightness and color uniformity measurements as a function of viewing angle for flat panel displays of up to 1.7 m x 1 m in size. It is intended primarily for developers of LCD, PDP, OLED and LED displays, as well as LED, CCFL and lamp-based backlights. The system can produce qualitative display images, as well as an extensive variety of quantitative plots, such as isoplots, CIE color analyses and radar plots, for any sampling area size and view angle; these measurements accurately eliminate the effect of the view angle to the camera. In addition, the system can even perform Mura defect detection. In contrast, previous instruments, based on either a scanned spot detector or a Fourier lens system, can only provide data for a single spot size, and don’t produce data on display spatial uniformity.

The PM-FPMS™ includes an automated goniometric motion system and system control, data acquisition and image processing software. It is intended to work with one of our PM Series™ Imaging Photometers and Colorimeters, which is selected independently.

PM-FPMS™ was developed using the ActiveX interface. The use of ActiveX controls in our software enables it to be extended by the user to perform customized, automated tests using software such as LabView, Matlab, VBA, VBScript, Javascript, C and C++.
