Abstract
The invention discloses a high-contrast screen comprising a high-reflection substrate and a light reflecting layer, wherein the light reflecting layer formed by a resin layer containing a plurality of light reflecting particles and light absorbing particles is coated on one surface of the high-reflection substrate. The invention can reduce the cost and is convenient to produce a screen with larger area; and the better contrast effect and the visual effect can be obtained by using the light reflecting particles to reflect the projected light and using the light absorbing particles to absorb the parasitic light.
Description
Technical field
The relevant high contrast screen of the present invention, the screen method for making of especially relevant high contrast screen.
Background technology
The screen form of projector probably can be divided into Xi Baimu, pearly-lustre curtain, optical microstructures curtain at present.Being made as a white flat paint coated on the base material of the white curtain of seat forms, and the advantage of Xi Baimu is cheap easy making, but Xi Baimu to poor, the visual effect of therefore receiving image is relatively poor.
Being made as beaded glass or plastic bead mixed to coat on the base material in resin of pearly-lustre curtain forms, and its advantage has and has higher brightness and visual angle, and its shortcoming is that cost of manufacture is high and be difficult for making.
The making of optical microstructures curtain is to be made on the base material with micro-structure, obtains good reflection and contrast and visual angle, and its shortcoming is difficult to make large-area screen for making optical microstructures cost height.
Other has the projection screen of multiple different structure, projection screen as 200739239 announcements of TaiWan, China publication, in order to receive projection light from a projector faces direction, comprise: a base material, have a plurality of characteristics, these these characteristics comprise that one is directed to the reflecting surface of this projector faces direction, these these reflecting surfaces in a first direction for bending so that a needed horizontal watching angle to be provided, and in a second direction for bending so that a needed vertical watching angle to be provided; Each person of these these characteristics one has the arcuation conical section of a substrate and this reflecting surface, and wherein this reflecting surface from this base extension the tip to this conical section; Though this screen increases the image contrast of receiving, its cost of manufacture is higher.
And for example the screen that discloses of TaiWan, China publication 200632518 comprises a directed diffusing layer, in order to diffusion with send from the light of specific direction and linearity and send light from other direction; No matter one isotropic diffusion layer is in order to the incident angle of light and diffused ray approximately isotropically; And a light reflection horizon, be arranged between directiona diffuseness layer and the isotropic diffusion layer.Though this screen has the projection surface and the projection surface with broad visual angle and natural visual field of high contrast, its cost of manufacture is higher.
Summary of the invention
For the screen that makes projector can reduce cost, and have better visual effect and can make more large-area screen, the object of the present invention is to provide a kind of high contrast screen.
Purpose for reaching, a kind of high contrast screen provided by the invention comprises: a base material; One reflection layer; Wherein this reflection layer is the reflection layer that includes the resin bed formation of a plurality of smooth reflective particles and light absorption particle in the one side coating one of a base material, utilizes the light of this light reflective particle reflective projection, utilizes this light absorption particle to absorb veiling glare.
Beneficial effect of the present invention: the invention provides a kind of high contrast screen, can reduce cost, and conveniently make more large-area screen, and utilize the light of light reflective particle reflective projection, utilize the light absorption particle to absorb veiling glare, make the screen of projector have better contrast effect and visual effect.

Embodiment
Other purpose of the present invention, effect see also graphic and embodiment, are described in detail as follows.
As shown in Figure 1, the high contrast of the present invention screen 1 comprises a base material 10 and a reflection layer 20; The one side 101 of base material 10 is in conjunction with reflection layer 20.Base material 10 can be plastic foil, for example materials such as PET (polyethylene terephthalate), PVC (Polyvinylchloride), OPP (the two-way extended polypropylene of high-tension intensity), PC coating materials such as (polycarbonate), sheet metal, paper, cloth.Reflection layer 20 is that one side 101 coating one resin bed 23 that contains a plurality of smooth reflective particles 21 and light absorption particle 22 at base material 10 constitutes.The shape of light reflective particle 21 and light absorption particle 22 can be for spherical or irregularly shaped; Light reflective particle 21 and light absorption particle 22 are of a size of 10nm (nanometer) to 0.5mm (millimeter).The material of light reflective particle 21 can be metal (high reflecting metals such as aluminium, silver, nickel, chromium) or mineral (quartzy, the contour reflection mineral of mica) etc.The material of light absorption particle 21 is a dark material, can be present printing material commonly used, for example: dark light absorbing materials such as dyestuff, carbon dust, cupric oxide.
The method for making of the high contrast of the present invention screen 1 is earlier light reflective particle 21 and light absorption particle 22 to be mixed in the resin according to certain proportioning; Resin is evenly coated the one side 101 of base material 10 again, treated promptly to form after the resin drying maturation resin bed 23 of the one side 101 that is incorporated into base material 10 then, resin bed 23 contains a plurality of smooth reflective particles 21 and light absorption particle 22.Resin can be transparent resins such as acryl resin, PU resin (polyurethane formic ether), epoxy resin; Coating process can be methods such as spraying, intaglio plate coating, half tone coating, scraper type coating.
As shown in Figure 1, the principle of the high contrast of the present invention screen 1 is the light that utilizes light reflective particle 21 reflective projections, and utilizes light absorption particle 22 to absorb veiling glare, the image that makes projector be projeced into high contrast screen 1 obtains better contrast effect, and makes spectators obtain better visual experience.
High contrast screen of the present invention is the reflection layer that includes the resin bed formation of a plurality of smooth reflective particles and light absorption particle in the one side coating one of a high reflective substrate; Can reduce cost and the more large-area screen of convenient making, and utilize the light of light reflective particle reflective projection, utilize the light absorption particle to absorb veiling glare, to obtain better contrast effect and visual effect.
The above record only for utilizing the embodiment of the technology of the present invention content, anyly is familiar with modification, the variation that this skill person uses the present invention to do, and all belongs to the claim that the present invention advocates, and is not limited to that embodiment discloses.
