Description
Technical field
The present invention relates to the application of single subsides thoroughly and projection imaging film, particularly a kind of list pastes and the application of projection imaging film in projection thoroughly.
Background technology
Single (One Way Vision that thoroughly pastes, claim again single-surface transparent), in " sunshade punching single-surface transparent ", being called for short of the title source of single-surface transparent, single thoroughly the subsides is to be made by the PVC material, it mainly is applicable to put up on the glass surface (for example subway door and window) of show window, glass door and window, glass curtain wall or the vehicles, can either keep the sun off, can advertise again, be a kind of good show and colour.This list sticks array thoroughly circular light hole, and the diameter of light hole is 1.8mm, and the area of light hole is 2.5mm
2, the hole back gauge of two adjacent light holes is 0.6 millimeter.
The saturating subsides of existing list mainly are applicable to " keeping the sun off and advertising ", but do not relate to projection application at all.In fact, single subsides field thoroughly and projection field are two fields that gap is larger, and making single research staff in subsides field thoroughly is mainly that the list of developing " can either keep the sun off, can advertise again " pastes thoroughly.The research staff of projection field focuses to the light beam of projector on projection material (projection screen), in order to find, can improve or improve the approach of projection quality.That is, single subsides field thoroughly and projection field are not occured simultaneously at all, and in other words, the research staff in one of them field can not pay close attention to or associate another field.
In existing projection process, a plurality of high power projector directly focuses to the light beam of high lumen on building, forms design or image on the wall of building and windowpane.When projection, there is the low poor problem of image quality of reflecting rate in the building of gravel wall; There is the problem of specular reflectance and transmission high (light refraction is to sky and be transmitted through building inside) in the building of glass curtain wall, and when serious, the building image quality of the building of gravel wall and glass wall is very poor, even at all can not imaging.
Therefore, projection field need to solve the high light transmittance of building and the problem of high projection quality in a hurry.
Summary of the invention
The technical problem to be solved in the present invention is thoroughly to paste and the application of projection imaging film in projection in order to provide single,, so that under the condition that keeps the inner normal intensity of illumination of building, improves the wall of building and the projection quality of windowpane.
The present invention solves above-mentioned technical matters by following technical proposals:
A kind of list is attached to the application in projection thoroughly, and its characteristics are, this list thoroughly pastes and comprises that a base membrane layer, this base membrane layer are gone into battle and show a plurality of light holes, and going back array on this base membrane layer has a plurality of separation primitives, and those light holes and those are separated primitive spaces and arranged.
Preferably, describedly be projected as the 3D projection.
The application of a kind of projection imaging film in projection, its characteristics are, this projection imaging film comprises a base membrane layer, this base membrane layer is gone into battle and is shown a plurality of printing opacity primitives, go back array on this base membrane layer a plurality of reflective primitives are arranged, those printing opacity primitives and those reflective primitive spaces arrange, and this projection imaging film also comprises a diffuse reflection coating, and this diffuse reflection coating and this base membrane layer bond successively mutually.The diffuse reflection coating is mainly used in diffuse reflection projection ray,, in order to improve gain, improves color saturation and the contrast of projected picture and promotes moire fringes inhibiting rate (relevant with formed interference between reflective primitive).
Preferably, be evenly distributed with a plurality of light-reflecting particles in this diffuse reflection coating.Those light-reflecting particles can improve the projection gain, improve the projection imaging quality and improve the moire fringes inhibiting rate.
Preferably, those light-reflecting particles are silver powder particle or pearl essence particle.
Preferably, the area of those printing opacity primitives is 0.07mm
2To 2mm
2
Preferably, this projection imaging film also comprises a glue-line and a bottom, and this diffuse reflection coating, this base membrane layer, this glue-line and this bottom bond successively mutually.By glue-line and bottom are set, base membrane layer can be torn from bottom, has therefore facilitated and has pasted and use.
Preferably, each printing opacity primitive is the light hole that is opened on this base membrane layer, and each reflective primitive is the zone that interconnects between adjacent two light holes.
Preferably, the material of this base membrane layer is vinyon, igelite or poly-para Toluic Acid's class plastics.That vinyon, igelite or poly-para Toluic Acid's class plastics have advantages of is cheap, durability is high and reflecting rate is high.
Preferably, those light holes are circular port, and the aperture of those light holes is 0.7 millimeter to 1.6 millimeters, and the hole back gauge of two adjacent light holes is 0.15 millimeter to 0.5 millimeter.
