Abstract

The invention relates to the technical field of display film manufacturing, in particular to a flexible optical composite film, wherein the composite film has a four-layer structure from top to bottom, which are: the first coating layer, the protective base layer, the filter base layer and the second coating layer. layer; the outer surface of the protective base layer facing away from the filter base layer is also provided with a covering coating; a self-adhesive layer is also provided between the filter base layer and the inner side of the second cladding layer, and the adhesive layer is used to connect the protective base layer and the second coating layer. The filter base layer is attached to the surface of the screen that needs to be covered; the composite film prepared by the present invention is not easy to cause stains on the screen, and the film structure has good acid and alkali resistance and light transmission effect. Rare earth oxide particles and rubidium are dispersed so that the filter layer structure can effectively filter most of the ultraviolet and blue light emitted by the screen, thereby reducing the irritation of blue light to the eyes and the fatigue of facing the screen for a long time.

Description

technical field [0001] The invention relates to the technical field of display film manufacturing, in particular to a flexible light composite film. Background technique [0002] With the improvement of people's living standards, more and more display screens of smart phones and electronic devices appear in people's lives. However, the screens of various electronic devices will have certain radiation when they are used, which will cause great threat and damage to people's health. The liquid crystal display screen of electronic equipment has the advantages of low power consumption, small size, and low radiation, and is applied to the screen display of TV sets and computers. Most of the current LCD screens use LED backlights. Since LED backlights require white light effects, blue light is generally used to excite phosphors to produce yellow light mixed with blue light to obtain white light, and then pass through color filters to obtain light of the three primary colors.
