System Overview:
The SS420 flat panel display measurement system is dedicated for flat panels and automatically characterize the image quality of all types of flat panel displays.  The SS420 system is a computer based measurement system that uses a goniometric method of collecting off-axis measurement data.   The SS420 system is a completely integrated system providing ease of use, flexibility and automatic test capabilities.

Accurate measurements of luminance and chromaticity are made utilizing a diffraction grating spectrometer, eliminating the need for color filters and the problems associated with filter matching.  A single fiber optic cable mates the collimating optics with the spectrometer.  A mechanical positioner allows movement of the detector to any location on the panel under test while a goniometric assembly provides the ability to make off-axis measurements.

In the typical operating mode, the positioning system moves the optics of the spectrometer to a desired measurement location on a vertically positioned flat panel. (As shown below)  The patterns and color of the display panel (UUT) are driven from a supplied pattern generator which provides both Analog and/or Digital signals or from an RS232 interface which provides a communication link with the drive electronics (laptop). A single click of the mouse initiates a variety of preprogrammed tests suites that generate reports of the measurement data.  The system is also offered in a mode allowing measurements of panels in the horizontal position.
