Description
Technical field
The present invention relates to a kind of composite optical adhesive tape with absorption blue light function, particularly a kind of OCA optical adhesive tape can for touch-screen with better adhesive property.
Background technology
In recent years, the development of touch-screen is very rapid, and along with growing with each passing day to multimedia information inquiry, people get more and more to the application of touch-screen.OCA optical adhesive tape due to possess water white transparency, transmitance more than 90%, consolidation strength is good, it is little to have cure shrinkage, do not produce the advantages such as xanthochromia, especially to ito glass and the advantage such as optical element is corrosion-free, so rely on its excellent process based prediction model, be widely used in touch-screen industry most.
Simultaneously along with the fast development of electronics technology, the requisite that the electronic product such as portable computer, TV has become people to live, people need the expensive time in the face of these electronic products every day, but include the very large blue light of human injury in the light that sends of the LED of these electronic products.Blue light refers to that wavelength is the high-energy light of 380nm ~ 480nm, it can penetrate lens and arrive retina, the epithelial cell of retinochrome is become feeble and die, photaesthesia cell is caused to lack nutrient, thus cause irreversible vision impairment, and blue light scattering probability when running into the fine particle in air is higher, easily produces dazzle, in addition blue light also can stimulate brain, suppress melatonin secretion and improve corticoid generation thus destroy hormone secretion balance directly affect sleep quality.
Therefore, develop a kind of anti-blue light optical adhesive tape, use it in electronic product, under the prerequisite with preferred optical performance, can also absorb blue light, this has very great meaning by the health of protection human body.
Summary of the invention
The invention provides a kind of composite optical adhesive tape with absorption blue light function, this composite optical adhesive tape has the effect of anti-blue light, royal purple high energy shortwave is had to the function of sorption enhanced, and 360nm ~ 500nm blue wave band filterability reaches more than 90%.
For achieving the above object, the technical solution used in the present invention is: a kind of have the composite optical adhesive tape absorbing blue light function, comprise a transparent substrate layer, the upper and lower surface of this transparent substrate layer is coated with the first anti-blue light adhesive layer, the second optical cement adhesion coating respectively, be coated with the first optical cement adhesion coating between described first anti-blue light adhesive layer and the first separated type material layer, between described second optical cement adhesion coating and the second separated type material layer, be coated with the second anti-blue light adhesive layer;
