Abstract
The invention discloses a kind of middle anti-light screens of short focus grating, and including screen ontology, the upper surface of the screen ontology is equipped with the optical grating construction of semi-cylindrical, and the surface of the optical grating construction is additionally provided with coating, and each component and quality proportioning of the coating are：Ink：Diluent=1:2.5‑3.The present invention in the upper surface of screen ontology by setting optical grating construction, light is by reflection and diffusing reflection principle, coating is reflected and is absorbed to light, therefore the interference of most of ambient light has been blocked, so that when daytime, light was strong, image sharpness in screen is high and bright in luster, reaches anti-light effect.
Description
Technical field
The present invention relates to a kind of screen, more particularly to a kind of middle anti-light screen of short focus grating.
Background technology
Projection screen is used in film, office, home theater, in convention occasion, for showing image, video text
The tool of part, sometimes screen, which can be applied, in the stronger scene of outdoor light, causes the image sharpness of projection low, influences to watch
Effect, therefore it is very necessary to design a kind of anti-light screen in view of the above problems, at present, common projection screen has：White modeling
Screen, glass fibre screen, pearl white screen, more than these types of screen be all to be made of uneven, irregular structure,
Visual angle is small, and clarity is low.
Invention content
The object of the present invention is to provide a kind of middle anti-light screen of short focus grating, using optical grating construction, by light reflection and
Diffusing reflection principle, coating are reflected and are absorbed to light, therefore have blocked the interference of most of ambient light so that in light on daytime
When line is strong, the image sharpness in screen is high.
To achieve these goals, the present invention uses following technical scheme：
A kind of middle anti-light screen of short focus grating, including screen ontology, the upper surface of the screen ontology is equipped with optical grating construction,
The surface of the optical grating construction is additionally provided with coating.
Wherein, the optical grating construction is set as multiple, and the shape of the optical grating construction is semi-cylindrical.
Wherein, the thickness of the optical grating construction is 0.15mm, and the width of the optical grating construction is 0.3mm.
Wherein, each component of the coating and quality proportioning are：Ink：Diluent=1:2.5-3.
Wherein, the component of the diluent and the mass percent of each component are：Cyclohexanone 50%, anti-plain boiled water 20%, vinegar
Acid butyl ester 30%.
Wherein, the component of the ink is PVC synthetic resin VYHH.
Beneficial effects of the present invention：By setting the optical grating construction of semi-cylindrical on screen surface, carry out ambient light
Regular and irregularities reflections and diffusing reflection, coating is reflected and is absorbed to ambient light, therefore has blocked big portion
The interference of time-sharing environment light, therefore when daytime, light was strong, the image sharpness in screen is high and bright in luster, reaches
To anti-light effect, the anti-light common screen of performance ratio is high by 10%, and angular field of view is wider, reduces visual fatigue；And this structure
Screen, structure and processing skill are relatively easy, and manufacture cost is relatively low.
Description of the drawings
The specific embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 shows the structure diagram of the present invention.
Reference sign：Screen ontology 1；Optical grating construction 2；Coating 3.
Specific embodiment
In order to make present invention solves the technical problem that, use technical solution, obtain technique effect it can be readily appreciated that below
With reference to specific attached drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, a kind of middle anti-light screen of short focus grating, including screen ontology 1, the upper surface of the screen ontology 1
Equipped with optical grating construction 2, the surface of the optical grating construction 2 is additionally provided with coating 3.
Preferably, the optical grating construction 2 is set as multiple, and the shape of the optical grating construction 2 is semi-cylindrical.
Preferably, the thickness of the optical grating construction 2 is 0.15mm, and the width of the optical grating construction 2 is 0.3mm.
Preferably, each component of the coating 3 and quality proportioning are：Ink：Diluent=1:2.5-3.
Preferably, the component of the diluent and the mass percent of each component are：Cyclohexanone 50%, anti-plain boiled water 20%,
Butyl acetate 30%.
Preferably, the component of the ink is PVC synthetic resin VYHH.
Preferably, the invention makes ambient light carry out rule by the optical grating construction in screen surface setting semi-cylindrical
The reflection and diffusing reflection of rule property and irregularities, coating is reflected and is absorbed to ambient light, therefore has blocked most of ring
The interference of border light, therefore when daytime, light was strong, the image sharpness in screen is high and bright in luster, reaches anti-
Light effect, the anti-light common screen of performance ratio is high by 10%, and angular field of view is wider, reduces visual fatigue；And the screen of this structure,
Structure and processing skill are relatively easy, and manufacture cost is relatively low.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims
Subject to.
