The invention relates to the technical field of display film manufacturing, in particular to a flexible light composite film, wherein the composite film has a four-layer structure from top to bottom, and the four-layer structure sequentially comprises the following components: the optical filter comprises a first coating layer, a protective base layer, a light filtering base layer and a second coating layer; a covering coating is also arranged on the outer side surface of the protective base layer, which faces away from the light filtering base layer; an adhesive sticker layer is arranged between the light filtering base layer and the inner side of the second coating layer and is used for attaching the protective base layer and the light filtering base layer to the surface of a screen to be covered; the composite film prepared by the invention is not easy to cause stains attached to the screen, the film structure has good acid-base resistance and light transmission effects, and the filter layer structure can effectively filter most of ultraviolet rays and blue light emitted by the screen by adding the dispersed rare earth oxide particles and rubidium in the base layer structure, so that the stimulation of the blue light to eyes and the long-term fatigue feeling of facing the screen are reduced. |
