Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present invention, and
The embodiment being not all of.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of protection of the invention.
As described in background, existing movie theatre viewing system, when ambient light is (as including the viewing Room
Reflected light of object etc. in light, the viewing Room) it can be superimposed upon in projected light after directive reflective viewing screen and produce
Noise, the contrast of projected image is influenceed, therefore, the projected image contrast of this movie theatre viewing system
It is relatively low.
Wherein, contrast is to weigh an important indicator of projected image quality, and it is projected picture maximum
Brightness LmaxWith minimum brightness LminRatio, i.e. contrast C=Lmax/Lmin.Because ambient light S is for details in a play not acted out on stage, but told through dialogues
Influence is very big, therefore, in the case of in view of ambient light S, contrast C=Lmax/(Lmin+S).By
This understands, as ambient light S and minimum brightness LminWhen close, contrast C reduces half, when ambient light S is big
In minimum brightness LminWhen, contrast declines even more serious.That is, ambient light how is eliminated to throwing
The influence of shadow picture contrast, it is one of existing projection field researcher urgent problem to be solved.
Based on this, the embodiment of the present application provides a kind of movie theatre viewing system, passes through transmissive viewing screen itself
Suppress the ambient light being incident in it, to solve to cause to project due to the influence of ambient light in the prior art

Carry out formation of polishing；Or frosted layer can conform to transparent layer surface formation.For transparent
Layer is not particularly limited with diffusing structure thereon, the application to its material and formation process.
For the transmissive viewing screen of above-mentioned offer, when projected light is incident to transmission type screen backstage, project first
Light is incident to optically focused microlens array, and projected light is converged and passed through by optically focused microlens array
Optical cavity volume array is incident to after transparent base layer；Each optical cavity body guiding optically focused lenticule of optical cavity volume array
Emergent light converge at the top surface of optical cavity body, and converge as the hot spot of a concentration, be then emitted to astigmatism
Layer；Diffusion layer, which is converted to the emergent light of the optical cavity volume array, vertically and horizontally has one
The emergent light of definite divergence angle is emitted to the viewing Room.
Further, since the transmissive viewing screen that the embodiment of the present application provides, sets in the gap of optical cavity volume array
Be equipped with light absorbs structure, when the ambient light from Movie House be incident to transmission type screen backstage, due to major part
The direction of ambient light and projected light is inconsistent, therefore, after optically focused microlens array and transparent base layer,
Inconsistent ambient light can be emitted from the edge of optical cavity body with projection light direction, then be inhaled by light absorbs structure
Receive, improve the ambient light from Movie House influences to caused by projected image；The viewing Room is come from addition, working as
Ambient light be incident to transmission type screen backstage, the ambient light can pass through diffusion layer formed scattering light outgoing, warp
Cross after diffusion layer and largely set about by light absorbs structure, and small part passes through optical cavity volume array, transparent base
Bottom and the outgoing of optically focused microlens array, improve the shadow to caused by projected image of the ambient light from the viewing Room
Ring.Therefore, no matter the ambient light from Movie House or the viewing Room, can be transmitted formula screen and be suppressed,
And then improvement ambient light influences to caused by projected image, to solve in the prior art due to the shadow of ambient light
The problem of ringing and causing projected image contrast relatively low.
Because the position of projector system Relative Transmission formula screen is fixed, and projector system and transmission
Between formula screen when reaching certain distance, projector system outgoing projected light reach transmissive viewing screen can
To be approximately directional light, now projected light vertical incidence to transmissive viewing screen, and the embodiment of the present application provides
Prismatoid optical cavity body, line and the parallel projection light of its end face center and bottom center are parallel relation.
But the distance between projector system and transmissive viewing screen it is smaller when, with reference to shown in figure 4,
A kind of projected light provided for the embodiment of the present application is incident to the schematic diagram of transmissive viewing screen, except projected light λ0
Central ray for outside vertical incidence to transmissive viewing screen 400, the equal oblique incidence of other light to transmission-type
Screen 400, and the light away from central ray, the normal angle a of itself and transmissive viewing screen 400 are got over
Greatly, therefore, in order to improve projected image effect, the prismatoid optical cavity body that the embodiment of the present application provides
Bottom center and end face center line relative to the normal of the transmissive viewing screen angle, with incidence
Projected light to the transmissive viewing screen is proportionate relative to the angle of the normal of the transmissive viewing screen.
Specifically with reference to shown in Fig. 5, Fig. 5 is a kind of structural representation for optical cavity volume array that the embodiment of the present application provides
Figure.When distance between projector system and transmissive viewing screen is smaller, the light of the embodiment of the present application offer
Cavity 120 is prismatoid optical cavity body, the bottom center of the prismatoid optical cavity body 120 and end face center
Line relative to the normal of the transmissive viewing screen 400 angle, with being incident to the transmissive viewing screen
Projected light λ0It is proportionate relative to the angle of the normal of the transmissive viewing screen 400.Wherein, reference chart
5 schematic diagram vertically, the bottom center of prismatoid optical cavity body 120 and the line of end face center are relative
In the angle b of the normal of the transmissive viewing screen 400, the projected light λ with being incident to the transmissive viewing screen0
It is proportionate relative to the angle a of the normal of the transmissive viewing screen 400, i.e. away from projected light λ0
Central ray projected light λ0Light and prismatoid optical cavity body bottom surface top surface the line of centres, itself and method
The angle of line is less and less.
