How to Use Imaging Colorimeters for FPD Automated Optical Inspection

Download Whitepaper
The imaging colorimeter AOI testing methods described in this note can be applied to multiple display technologies and can be used for both FPD (LCD, plasma, OLED) and projection displays. By providing rapid, repeatable measurements that are correlated to human visual perception, and by being able to numerically characterize them, these methods allow display defects to not only be identified, but also classified by cause.
