We have
elaborated some basic application area for polarizer film, we would like to
reveal the defects found on polarizer film together with possible cause.
Mechanical Defect.
The
polarizer film comes in big sheet dimension, manufacturer will cut the film
into desire size. The film may encounter
various mechanical damages if the manufacturer does not strictly follow
handling precaution guideline.
Various kind of surface scratches are the main mechanical defect we encounter if it does not handle properly. Below are the main mechanical damages:
Surface
scratch

mark
Deformation
Dimensional Defect.
During
cutting process, we have a set of operation guideline to ensure the cutting
tools are set properly to ensure polarizer film is correctly cut.
Mura Defect
Mura Defect. Mura
is a kind of defect whereby the light is not transmitted as expected. As the image shown, there already a black
