How-To Guide: Automated Visual Inspection and Correction (Demura) of OLED Displays

Methods for measuring luminance and chromaticity of all pixels in high-resolution OLED displays

The Radiant Vision Systems solution for OLED inspection and correction helps manufacturers of OLED devices improve product quality and yield. A ProMetric® imaging colorimeter or photometer provides the high optical resolution necessary to measure OLED displays on the pixel and sub-pixel level. With TrueTest™ analysis software, these measurements can be used to correct individual display pixels. This process, referred to as “demura,” adjusts the luminance and/or chromaticity of each OLED pixel to produce displays with an entirely uniform appearance.

White Paper: Fractional Pixel Method for Improved Pixel-Level Measurement and Correction (Demura) of High-Resolution Displays

A fractional pixel registration and measurement method improves the accuracy of pixel-level values measured by standard-resolution systems, ensuring effective qualification and demura of high-resolution OLED, miniLED, and microLED displays.

As display resolutions increase, imaging systems are challenged to continue to provide accurate pixel-level measurements while applying increasingly limited relative imaging resolution during single-image analysis (necessary for production efficiency). A fractional pixel registration and measurement method improves the accuracy of pixel-level values measured by standard-...
