Automated Visual Inspection and Correction (Demura) of 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.
