AI Technical Summary
Existing transparent optical hardening films are easily broken when subjected to impacts, lack shatterproof screen protection, and are not very effective.
The film employs a combination structure of carbon fiber frame, elastic buffer layer, hardening layer and AR nano oleophobic film layer. The elastic buffer layer is formed by curing a mixture of acrylic resin and rubber with ultraviolet light. Combined with double-sided adhesive layer and release layer design, the film enhances the screen shatterproof performance.
It effectively prevents the transparent optical hardening film from cracking and chipping, extends its service life, reduces screen contamination, improves the user experience, and facilitates the installation and removal of the film.
