Patent ID: 8894797

Claim:
A method of splicing polarized films comprising steps of: providing a substrate; attaching a first polarized film to the substrate, wherein an anti-adhesive material is mounted on an upper surface and a lower surface of a side portion of the first polarized film; attaching a second polarized film to the substrate so that a side portion of the second polarized film is correspondingly overlapped with the side portion of the first polarized film and is correspondingly attached to the anti-adhesive material on the side portion of the first polarized film; correspondingly cutting off the overlapped side portions of the first polarized film and the second polarized film to form a separated part of the side portion of the first polarized film and a separated part of the side portion of the second polarized film; removing the separated parts of the side portions from the first polarized film and the second polarized film; and performing a flatten treatment to the cut side portions of the first polarized film and the second polarized film which splices the first polarized film to the second polarized film, wherein the flatten treatment includes a rolling process to perform surface rolling on the cut side portions and a bubble-remove process to remove bubbles occurred during performing the surface rolling on the cut side portions.
