PM-OLED™ OLED Measurement System

Complete solution for OLED production testing.

PM-OLED™ is a complete, turnkey solution for test and inspection of full color OLED displays in on-line production, off-line production and even R&D environments. The system delivers rapid, high precision measurements of OLED luminance and chromaticity across an entire substrate, over a single display, or even for an individual pixel. The system can also automatically identify row and column defects, Mura defects, and both pixel and sub-pixel defects. PM-OLED™ is useful for tasks as diverse as high-speed production testing of all the OLED displays on a single glass substrate, or performing detailed R&D studies of sub-pixel defects and shrinkage over time.

PM-OLED™ is intended to supplement or replace human visual inspection, which is currently the primary method of OLED inspection. It can readily be configured to control OLED power supply switching for automated measurement of display luminance and color characteristics. PM-OLED™ then automatically provides the operator with either detailed information, or just simple pass/fail indications based on preprogrammed target values for luminance and color. The same level of automated convenience is available for testing based on defect detection. For development purposes, options for measuring luminance, color and pixel dimensions as a function of time can be added.

PM-OLED™ includes a PM-1400 Series Colorimeter, in addition to proprietary data acquisition and image processing software. A range of camera optics is available to provide a choice of field of view and spatial resolution.

PM-OLED™ 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++.
