Abstract

The invention discloses an anti-UV paint composition and film, which is characterized by the following: the paint composition can be coated on the base, which makes base display good anti-UV effect; the anti-UV film contains at least one face with at least one layer of anti-UV paint composition, which possesses excellent weatherability for LCD.

Description

technical field [0001] The invention relates to a coating composition, in particular to a coating composition with anti-ultraviolet performance and a film comprising an anti-ultraviolet coating, belonging to the technical field of coating processing and its application. Background technique [0002] A backlight module is one of the key components of an LCD panel. Since the liquid crystal itself cannot emit light by itself, the main function of the backlight module is to provide a uniform and high-brightness light source for the liquid crystal panel. A uniform surface light source product, thereby providing the backlight source required by the product so that it can display images normally. At present, the backlight module has a great influence on the manufacturing cost and the use quality of the liquid crystal display. [0003] The more common backlight modules on the market are classified according to the position of the lamp tube, and are mainly divided into a side struc...
