Abstract

The invention relates to a novel optical protection film, and particularly relates to a light transmission film or plate for preventing blue light and ultraviolet light and an application thereof. In order to solve a problem that the current light transmission film or plate does not have a function of preventing blue light and ultraviolet light, the invention provides a light transmission film or plate for preventing blue light and ultraviolet light and an application thereof. The light transmission film or plate comprises a function layer, a base material layer and a protection layer; one side of the base material layer is provided with the function layer, and the other side of the base material layer is provided with the protection layer; a raw material of the base material is composed of the following materials: a resin master batch: 70,0-99.0%; a plasticizer:0.5-10%; a blue light absorbent: 0.1-5%; an ultraviolet light absorbent: 0.1-5%; and other addictives; and the percentage is weight percentage. The transmission film or plate for preventing the blue light and the ultraviolet light can reduce harm of the blue light on human eyes, protects human skin and has a longer service life.

Description

technical field [0001] The invention relates to a new type of optical protective film, in particular to a display screen that can be applied not only to electronic products such as mobile phones, computers, televisions, instruments, etc. Anti-blue light and anti-ultraviolet light translucent film or plate and application thereof. Background technique [0002] Light-transmitting film or light-transmitting plate is a film or plate with optical functions that converts point and line light sources into line and surface light sources. When the light passes through the light-transmitting film or plate, many phenomena of refraction, reflection and scattering will occur to the light, thus causing corresponding optical effects, which belongs to the field of optical thin films. Light-transmitting film or board is widely used in backlight modules of flat panel displays and new lighting sources, such as TVs, computer monitors, notebook computers, mobile phones, digital cameras, MP4 pla...
