Abstract
The utility model discloses a kind of optical films, including substrate layer, the substrate layer side is incidence surface, and the substrate layer other side is light-emitting surface, it is equipped with antireflection layer on the outside of the incidence surface, the optical structure layers that can be reduced reflected light and improve optical gain are equipped on the outside of the light-emitting surface.The utility model is applied in combination using the first optical texture of micron order prism structure and second optical texture of nanoscale prism structure, since nanoscale prism structure is less than optical wavelength, so that light wave is beyond recognition out the micro-structure, then it is in consecutive variations along depth direction in the refractive index of material surface, the reflex caused by refractive index change dramatically can be reduced, reflected light can be reduced, optical gain is improved；Since antireflection layer is nanometer scale, so reflected light can be further reduced, light penetration is improved, improves optical gain.
Description
Technical field
The utility model is related to optical device field more particularly to a kind of optical films.
Background technology
When light traverses glass and air contact surfaces, light can not only reflect, it also occur that reflection.Reflection
Not only can off-energy, cause to be imaged dimmed, then optical film comes into being.Optical film is made of thin layered medium,
A kind of optical medium material of light beam is propagated by interface.The application of optical film is ubiquitous, from glasses plated film to mobile phone, electricity
LED illumination etc. is arrived in the liquid crystal display of brain, TV again, it, which is full of, writes the every aspect that we live, and makes our life more
Add rich and varied.
For another example disclosed in Chinese patent literature CN105074553 it is a kind of have back to first structure surface and second
The optical film of structured surface, the optical film include：The prism of the multiple extensions formed in the first structure surface；
The lenslet of the multiple extensions formed in second structured surface；And the wherein described prism and the lenslet are by cloth
It is set in the one-to-one relationship in lenslet and prism；And wherein at least some described prisms are composite prisms, each
Composite prism has compound two inclined surfaces and acute vertex, the such composite inclined surface tool of each of each composite prism
There are tip portion, base segments and the middle section being arranged between the tip portion and the base segments, in described
Between part form first side shape with the tip portion and form second side shape with the base segments, and wherein
The first side shape be spill and the second side shape be convex or the first side shape be convex simultaneously
And the second side shape is spill.Although the optical film can realize blast, since prism cannot be effectively eliminated
Structure because external light reflection optical phenomenon, so the unconspicuous feelings of effect that are serious there are reflected light and improving optical gain
Condition, light transmittance are only up to 23%.
Utility model content
To overcome disadvantages mentioned above, it can reduce reflected light the purpose of this utility model is to provide one kind and improve optics increasing
Benefit optical film with obvious effects.
In order to reach object above, the technical solution adopted in the utility model is：A kind of optical film, including substrate layer, institute
It is incidence surface to state substrate layer side, and the substrate layer other side is light-emitting surface, and antireflection layer is equipped on the outside of the incidence surface, described
The optical structure layers that can be reduced reflected light and improve optical gain are equipped on the outside of light-emitting surface.
Preferably, the optical structure layers include the first optical structure layers and the second optical structure layers, first optics
Structure sheaf and the setting of the second optical structure layers interval.
Preferably, first optical structure layers are prism structure.
Preferably, second optical structure layers are the prism structure of multiple extensions.
Preferably, the peak altitude range of first optical structure layers is 1nm<H≤100μm.
Preferably, the peak altitude range of second optical structure layers is 10nm≤h≤30nm.
Preferably, the depth-to-width ratio of first optical structure layers is 0.3-3.
Preferably, the depth-to-width ratio of second optical structure layers is 0.3-3.
Preferably, the antireflection layer is the lens arrangement of multiple extensions, and the overhead height of the lens arrangement is ranging from
1nm≤R≤20nm。
Preferably, the substrate layer is using transparent materials such as PET, PS or PC.
The beneficial effects of the utility model：Using the first optical texture and nanoscale prism structure of micron order prism structure
The second optical texture be applied in combination, since nanoscale prism structure is less than optical wavelength so that it is micro- that light wave is beyond recognition out this
Structure is in then consecutive variations along depth direction in the refractive index of material surface, can reduce caused by refractive index change dramatically
Reflex, it is possible to reduce reflected light improves optical gain；Since antireflection layer is nanometer scale, so can further subtract
Few reflected light, improves light penetration, improves optical gain.
