In this paper we reported a novel technology to improve Horizontal Mura. The relationship between process/material and horizontal light line is analyzed no matter wet or dry. After a lot of experimental verification and analysis of the mechanism. A method to assess Horizontal Mura risk is developed with corresponding Cu acid standards/process change to ensure product reliability requirements are met.
