Description
Technical field
The utility model is related to a kind of film, more particularly to a kind of high-definition back projection film.
Background technology
Back projection is for orthographic projection, and positive throwing is the same side that observer and projector are located at reflective viewing screen,
The illumination come out from projector is mapped to screen, and observer is it is seen that the light that screen reflection is returned, light have passed through reflection
With refraction；Rear-projection is the both sides that observer and projector are located at rear projection screen, projector is mounted on the bottom in fuselage, from throwing
The illumination that shadow machine is cast out has part light and penetrates when being mapped to translucent rear projection screen, observer is it is seen that transmit
Light.Because in back projection technique, projector and screen in homonymy, so back projection film have on ease of use it is very big excellent
Gesture.The defects of current back projection film both domestic and external is primarily present several respects, first, viewing angle is limited, universal gain visual angle exists
40-50 degree, second is that clarity and contrast be not high, color rendition degree is poor, third, translucent effect and drop shadow effect are subject to light to expand
Powder influences, it is impossible to reach the requirement of high definition.Disadvantage mentioned above constrains a wide range of popularization of the high-definition back projection film in projection field.
Utility model content
The purpose of this utility model is to provide a kind of picture is clear, contrast is high, the high-definition back projection film of function admirable,
It solves the problems, such as to propose in background above technology.
Technical solution is used by the utility model solves its technical problem：
A kind of high-definition back projection film, including super permeable membrane layer, filter layer, light scattering layer and the rear-projection film layer set gradually, institute

The all-transparent polyester film of imaging coating is equipped with for surface, imaging coating is arranged on the one side that rear-projection film layer deviates from light scattering layer.
Preferably, the super permeable membrane layer surface is equipped with scratch resistant layer, scratch resistant layer is the group containing the anti-spread coated paint of light curable type
It closes object and is coated on the preventing from scraping film that the thickness that super permeable membrane layer surface is formed is 5 ~ 15 μm.
Preferably, the filter layer is arranged on jetting type coated form between super permeable membrane layer and light scattering layer, filter
The thickness of layer is 5 ~ 25 μm.
Preferably, the rear-projection film layer is additionally provided with the light of 10 ~ 50 μm of grain size in the side surface equipped with imaging coating
Learn glass microballoon.Optical glass microballon can improve brightness, contrast and the increase visible angle of imaging.
Preferably, the super permeable membrane layer thickness is 10 ~ 35 μm, light scattering layer thickness is 5 ~ 30 μm, and rear-projection film layer is thick
It spends for 15 ~ 60 μm.
The beneficial effects of the utility model are：
The high-definition back projection film of the utility model, equipped with super permeable membrane layer and filter layer, image high definition, imaging effect is good, it
It is low with image contrast to solve the problems, such as that conventional rear projection film angular field of view is limited, has gorgeous imaged color can with broad
Depending on visual angle, the super large imaging area of no splicing can be obtained by being affixed directly to transparent rigid substrate surface, using flexible, be fitted
With in extensive range.
