Abstract
The present invention relates to an optical film. It includes a base material, and is characterized by that at least one base material surface is coated with a coating layer with ultraviolet light absorbing capacity. The invented optical film has good weatherability and has good effect for absorbing UV ray.
Description
Technical field
The invention relates to a kind of blooming, it comprises a base material, it is characterized by to have at least a substrate surface to be coated with the coating with ultraviolet absorption ability.Blooming of the present invention can be used on glass or flat-panel screens in, have good against weather, and have and absorb ultraviolet effect.
Background technology
If human body tans by the sun too much ultraviolet ray, cause cataract, cutaneum carcinoma easily, burn and symptom such as thickization of skin produces, therefore ultraviolet ray has many adverse influences for human body.
In addition,, can damage, situations such as yellow, embrittlement and distortion take place easily material if material contacts ultraviolet ray for a long time.
In order to reduce ultraviolet injury, people constantly seek strong and effective ultraviolet absorption material for many years, as ultraviolet light absorber, but ultraviolet light absorber is an organic substance, has short, shortcoming such as toxicity is big of life-span, for improving above-mentioned shortcoming, progressively development uses the nano grade inorganic particulate to replace ultraviolet light absorber recently.
LCD (Liquid Crystal Display, LCD) imaging, at first utilize a backlight (back lightsource) to project light source, these light sources can be earlier through a Polarizer and then through liquid crystal molecule, this moment, the arrangement mode of liquid crystal molecule can change the angle of the light that penetrates liquid crystal, and these light are again through the colored filter (color filter) and another piece Polarizer in the place ahead then.Therefore,, just can control the light intensity and the color of last appearance, and and then change the color combination that the different depths as long as change to stimulate the magnitude of voltage of liquid crystal molecule.
The light that backlight is launched contains ultraviolet ray (UV), causes the macromolecule resin yellow in the blooming easily, causes reflecting effect to weaken and the aberration problem of LCD.
This case the inventor find through broad research, coating with ultraviolet absorption ability is arranged in the blooming surface-coated, not only do not influence the density of blooming, again can be with the UV light absorption in most of backlight, and can make blooming have permanance and can reduce its thickness.Use this kind blooming, do not need to change relevant design and mould, the brightness of liquid crystal display is improved, can effectively solve the aforesaid drawbacks.
