Abstract

The invention relates to the technical field of display film manufacturing, in particular to a flexible light composite film which is of a four-layer structure from top to bottom and sequentially comprises a first coating layer, a protective base layer, a light filtering base layer and a second coating layer; a covering coating layer is further arranged on the outer side surface, back to the lightfiltering base layer, of the protective base layer; an adhesive sticker layer is further arranged between the light filtering base layer and the inner side of the second coating layer, and the adhesive sticker layer is used for attaching the protective base layer and the light filtering base layer to the surface of a screen needing to be covered; the flexible light composite film prepared by theinvention is not easy to cause stains attached to screens; and the film structure has good acid and alkali resistance and light transmission effect, and the light filtering layer structure can effectively filter most of ultraviolet rays and blue light emitted by screens through dispersed rare earth oxide particles and rubidium added in the base layer structure, so that the stimulation of the bluelight to eyes and the fatigue feeling caused by facing screens for a long time are reduced.

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.
