Abstract

The invention relates to an optical film, especially to a blue light preventive light transmitting film, used for a screen of a flat panel display or the illumination field, and an application of the light transmitting film, and aims at filtering high-energy short-wave blue light, which damages the eyes, of the display and illumination equipment. The light transmitting film / plate comprises a function layer, a substrate layer and a protective layer; the function layer and the protective layer are arranged at two sides of the substrate layer respectively; at least one of the function layer and the protective layer is added with blue light absorbing resin particles; and the blue light absorbing resin particles comprise resin and a blue light absorbent which is an organic dye. The blue light preventive light transmitting film can achieve the effect of preventing blue light, and has a long life of blue light prevention as well as excellent optical performance.

Description

technical field [0001] The present invention relates to an optical film, more specifically, to a light-transmitting film or plate for anti-blue light used in the field of flat panel display screens or lighting and applications 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 players, GPS navigators and various daily and industrial lighting sources Wait. [0003] Studies h...
