More Information
Summary:The utility model provides a COP multi-layer composite film, the lower side of the COP multi-layer composite film faces a light source, the upper side of the COP multi-layer composite film faces a liquid crystal panel, and the COP multi-layer composite film sequentially comprises a diffusion coating (10), a core layer (20), a first adhesive layer (30), a first PET base material layer (40), a second adhesive layer (50), a prism structure (60), a second PET base material layer (70) and a back coating (80) from top to bottom. The first adhesive layer (30) is formed by combining an adhesive layer A and an adhesive layer B, the adhesive layer A is coated on the lower surface of the core layer (20), and the adhesive layer B is sprayed on the upper surface of the first PET base material layer (40). The first adhesive layer (30) of the COP multilayer composite film can be matched with the core layer (20) and the first PET base material layer (40), so that warping after bonding can be avoided under the condition of su
