Transparent Display-Type Glue-Free Flexible Copper-Clad Film (PET)
Category:
Product Advantages
The transparent, adhesive-free flexible copper-clad laminate (PET) boasts high bendability and excellent light transmittance. While maintaining lower costs, it also delivers outstanding electrical and thermal performance, demonstrating tremendous potential in display panels, touch screen panels (TSPs), COFs, and a wide range of other display applications.
Product Applications
Transparent displays, foldable flexible displays, and crystalline film screens, etc.
