Abstract

A scratch proof film is prepared for arranging a microstructure layer at bottom side of base material and a scratch proof layer on top side of base material, setting concave-convex structure on scratch proof layer, making scratch proof layer have fog degree of 30-98% and surface resistivity of 10 to the power 8-10 Omega/„ as well as pencil hardness of 3H.

Description

technical field [0001] The invention relates to an optical film, in particular to a scratch-resistant film with a hardened coating, in particular to a scratch-resistant film applicable to a liquid crystal display. Background technique [0002] The liquid crystal panel itself does not emit light, so the backlight module as a source of brightness is an important component of the LCD display function, and the backlight module is very important for improving the brightness of the liquid crystal display. At present, the most economical and simple solution is to install various optical films in the backlight module. This method does not need to change any component design or consume extra energy, but it can improve the brightness of the LCD panel and make the light source the best. be utilized efficiently. FIG. 1 is a simple schematic diagram of various optical films contained in a backlight module. As shown in FIG. 1 , the optical film contained in the general backlight module ...
