Abstract

This standard was technically approved by the global Flat Panel Display – Metrology Committee. This edition was approved for publication by the global Audits & Reviews Subcommittee on January 20, 2010. Initially available at www.semi.org in February 2010.

 

Specific definitions and quantifications of Mura are not consistent for many FPD manufacturers. Though there are standards for quantification of Mura, they are only used for limited types of Mura and are not practical in real varied cases. Currently it is still difficult to implement instruments to replace human inspectors for Mura inspections of LCDs. Therefore, it is necessary to standardize the classification of Mura for LCD.
