CN203876331U - Hard coating film with double functions of fog resistance and glare resistance - Google Patents

Abstract

This utility model belongs to the field of optical film technology, and specifically relates to a hardening film. To overcome the limitation of existing hardening films having only one function, this utility model provides a hardening film with both anti-fogging and anti-glare functions. The hardening film includes a substrate, with an anti-fogging hardening layer on one side and an anti-glare hardening layer on the other side. Because of the anti-fogging layer, this hardening film effectively prevents moisture from condensing on its surface, eliminating the impact of moisture on vision. Furthermore, the anti-glare layer on the other side effectively reduces light reflection, eliminating the impact of glare on vision. This hardening film, possessing both anti-fogging and anti-glare functions, overcomes the shortcomings of single-function applications, thus allowing for wider application in protective films and cover plates for liquid crystal display devices.
