Description
Technical field
The utility model relates to the backlight of display device, particularly a kind of display backlight structure reducing blue light harm.
Background technology
Current masses are more deep to the understanding of uv damage eyes, but high energy shortwave blue light to the extent of injury of human eye not second to ultraviolet power, just there is the knowledge blind area understood blue light in a lot of people.In fact, in visible ray, blue light is a kind of high energy short wavelength light having energy, blue light can just penetrate the crystalline lens of glasses easily and reach retina place, entire glasses is caused to a kind of infringement of spectrochemical property, the oxidizing process of eyes macular region can be accelerated rapidly and injury is greatly produced to eyes.High energy shortwave blue light, to eye ground and lenticular destruction, is called " blue light injury " phenomenon.
Especially teen-age crystalline lens is limpid especially, equally can not carry out adjustment to blue light with adult to filter, blue light is also easy to bring out amphiblestroid pathology at the bottom of teenagers eyes simultaneously, in addition, because lenticular yellow is grown, blue light injects the degree of eyes and quantity also has very large relation with the age, when 7 to 19 years old, blue light is injected eye ground and is about 85%, more than the adult of other age brackets is many, at this point, the period that blue light exists greateset risk and maximum injury to eyes is exactly adolescence, therefore for teenager, prevention high energy shortwave blue light must be learned to the injury of own health.Teenager every day, as ipad and TV etc., these electronic products also can send strong blue light, can say, blue light is ubiquitous to teen-age injury in the face of various screen light source.So far still do not have effective medicine to stop blue light to retina and lenticular injury, and physical principle can only be taked to carry out pre-anti-blue light injury.
How the main machine of current technical research is avoided endangering maximum high energy shortwave blue light (main concentrated 380um to 420um light wave) to human eye.Avoid blue light harm for reaching, prior art mainly through changing the lampshade of white LED luminary, by adding yellow fluorescent powder, the blue light wave in the LED of reduction.
Above mainly for the part of LED light emitting source, the method has born deficiency, can only be defined in the lampshade of LED.But for other fluorescent lamp and other illuminating sources, have no idea to reach and reduce blue light harm.Absorb as passing through, the blue light harm part in restriction paths path is then the part of techno-absence instantly.
In existing display device, equipment self cannot reduce or filter blue light harm, mainly by the mode of anti-blue glasses or film on surface.This mode causes quite not convenient to user, and needs to safeguard, does not possess the convenience of use.
