Description
Technical field
The present invention relates to display technology field, more particularly to a kind of display and its anti-blue light film.
Background technology
Nature shows white light without single white light, blue light after being mixed with green glow, feux rouges in itself.Green glow and feux rouges energy
Amount is smaller, and smaller to eye irritation, blue light ripple is short, and energy is high, LED, display device backlight in remain substantial amounts of blue light, this
Sample make it that artificial light is whiter, brighter, and some especially white bright light give people the sensation of blueing always, draws here it is blue light ratio is too high
Rise.All contain largely not in the visible ray that the various novel artificial light sources such as all kinds of computers, television screen, electricity-saving lamp are sent
The shortwave blue light of regular frequency.Wavelength is between 400~500nm.
It is chronically exposed under blue light, easily causes eye injury, particularly cause macular diseases.Blue light can penetrate crystalline
Body reaches retina, and optical damage is caused to it, accelerates the oxidation of macular area cell, produces a large amount of free radicals, cause cataract,
Macular area is degenerated.The specific harm of blue light includes：1) blue light can go directly retina, cause myopia；2) blue light can excite brown color
Element, it is that skin produces macula lutea, the major reason of freckle；3) blue light can cause the damage of fundus after cataract operation；4) blue light can
Trigger the dimness of vision, cause visual fatigue, cause VDT syndromes；5) blue light can trigger dazzle；6) blue light can suppress to take off black
The secretion of element, sleep is bothered, improve the incidence of itself major disease.
Therefore the blue light of display device is eliminated or weakened, is highly desirable to protecting eyes from blue light injury.At present
The general mode for weakening blue light has two kinds, and a kind of mode is to adjust blue led chip emission peak wavelength, by LED main product
The emission peak wavelength in area, by 445nm-450nm section, by building brilliant technique adjustment to longer generation peak value, but this
The shortcomings that kind mode is the reduction of blue light excitated fluorescent powder efficiency, the reduction of integral LED luminous efficiency is brought, simultaneously as colour temperature
Deviate main producing region, away from the market demand, production cost drastically raises.The second way, usually set up in LCD reflection diaphragm
