Abstract
The utility model discloses a flexible film projection cloth of diffuse reflection, including film body and tiny line layer, its characterized in that: one side of film body is provided with the light-shield layer, film body one side is provided with silver grey matte layer, one side of silver grey matte layer is provided with tiny line layer, this patent light-shield layer plays the effect of separation light, consequently can not receive the color influence of wall because the product is opaque, reduce light loss, silver grey matte layer carries out diffuse reflection to the light that the transmission got into in the projection curtain, the angle scope of the emergent light after making the reflection increases, the nanometer particle has in the tiny line layer, projection light is through nanometer particle line texture structure refraction, the luminance of emergent light has been promoted, and have certain diffusivity to incident light, make incident light atomizing, the small-angle incident light is concentrated to positive outgoing and is in order to guarantee wide visual angle, so can not harm viewer's eyes, and the cost is also lower.
Description
Technical Field
The utility model relates to a film projection cloth technical field specifically is a flexible film projection cloth of diffuse reflection.
Background
Projection screens are used in conjunction with projectors for displaying images and video in movie theaters, office areas, home theaters, large conferences, and the like. At present curtain commonly used can divide into white curtain, grey curtain, metal curtain etc. according to the colour, can divide into traditional white curtain, soft curtain, glass fibre curtain, sound transmission curtain etc. according to the material, and the user can select the curtain of different grade type according to the demand of different occasions.
For example, when the service environment of the curtain is better, the most traditional white curtain can meet the service requirements, the white curtain and the gray curtain are more commonly applied in a medium-long-focus scene, and the cost angle is low, but the projection brightness of the curtains is low, when the ambient light is stronger, the projection is unclear, the contrast is lower, the requirement on the service environment of the glass fiber curtain is higher, the cost is also higher, in addition, the very many projection cloths on the market can have the phenomenon of dazzling in reflection, the dazzling is injured, and therefore the dazzling-free projection cloth needs to be provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a flexible film projection cloth of diffuse reflection to solve the current projection cloth of proposition and use inconvenient problem among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme, a flexible film projection cloth of diffuse reflection, including film body and tiny line layer, its characterized in that: a shading layer is arranged on one side of the film body, a silver gray matte layer is arranged on one side of the film body, and a fine grain layer is arranged on one side of the silver gray matte layer.
Preferably, the silver gray matte layer and the fine texture layer are combined to form a diffuse reflection layer.
Preferably, the silver gray matte layer is provided with a light absorbent material.
Preferably, the light-shielding layer is a black opaque layer.
Preferably, the material of the film body is EVA or PEVA or TPE material.
Compared with the prior art, the beneficial effects of the utility model are that: the effect of separation light is played at first to the light shield layer to the technical bright point of this product, consequently, the product is opaque can not receive the colour influence of wall, reduce the light loss, silver grey matte layer carries out diffuse reflection to the light that the transmission got into in the projection curtain, make the angular range increase of emergent light after the reflection, nanoparticle has in the tiny line layer, projection light is through the refraction of nanoparticle line structure, the luminance of emergent light has been promoted, and have certain diffusivity to incident light, make incident light atomizing, the positive outgoing is in order to guarantee wide visual angle to small-angle incident light, can alleviate the halo phenomenon simultaneously, can prevent to produce reflection of light and bright point on image projection to this projection curtain, so can not harm viewer's eyes, and the cost is also lower.

fig. 2 is a front view of a diffuse reflection flexible film projection cloth according to the present invention;
fig. 3 is an exploded view of the diffuse reflection flexible film projection cloth of the present invention;
in the figure: 1. the film comprises a film body, 2 a shading layer, 3 a silver gray matte layer, 4 a fine grain layer. .
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a flexible film projection cloth of diffuse reflection, includes film body and tiny line layer, its characterized in that: one side of film body is provided with the light shield layer, film body one side is provided with silver grey matte layer, one side of silver grey matte layer is provided with tiny line layer, and silver grey matte layer and tiny line layer combination are the diffuse reflection layer, and silver grey matte layer is provided with the light absorbent material, and the light shield layer is black euphotic layer, and the film body material is EVA or PEVA or TPE material.
The working principle is as follows: when using the flexible film projection cloth of this diffuse reflection, fix film projection cloth on the wall earlier during the use, then open projecting apparatus and carry out the illumination to the front of product, then from our film projection cloth production image, this product can alleviate the halo phenomenon because be provided with the line with extinction auxiliary agent material, can prevent to throw and can produce reflection of light and bright spot to this projection cloth curtain when the image, so can not injure the working process that is this novel patent more than the sight's the eyes.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
