Zara and Rubbing Mura Research

The dependence of Zara and Rubbing Mura on Rubbing intensity has been studied.The experimental result show that,when Rubbing intensity is low,Zara easily occurs,and when rubbing intensity is high,rubbing Mura easily occurs.By selecting the right rubbing intensity,the incidence of Zara and rubbing Mura can be reduced.In addition,through using FIB to observe the surface of the substrate,it is found the reason of FFS product prone to occur Zara and Rubbing Mura
