The embodiments of the invention provide a kind of rear-projection combination and its rear projection screen, reduces and spells while anti-dazzle is realized
The width of black surround is connect, improves the integrality of rear-projection combination imaging.
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Fig. 2 is refer to, Fig. 2 is a kind of section structural representation of rear projection screen provided in an embodiment of the present invention.
The rear projection screen, applied to rear-projection combination, including optical glass layer 1, it is pasted on the anti-of optical glass layer surface
Dazzle film 2 and screen frame 3；The lower surface of anti-dazzle thin-membrane 2 is provided with gum, and anti-dazzle thin-membrane 2 passes through gum and optics glass
The surface of glass layer 1 bonds, and stretches out preset length in the surrounding of optical glass layer 1, and film extension 21 is used for light
The side for learning glassy layer 1 is fixedly connected with screen frame 3.
Specifically, by optical glass layer 1 and it is pasted onto the anti-of the surface of optical glass layer 1 in rear projection screen in the application
Dazzle film 2 replaces glare proof glass layer of the prior art, and the back side of the anti-dazzle thin-membrane 2 in the application carries the back of the body
The anti-dazzle thin-membrane 2, can directly be pasted onto the surface of optical glass layer 1 by glue, and the surface is the appearance of optical glass layer 1
Face, when anti-dazzle thin-membrane 2 to be pasted onto to the surface of optical glass layer 1, four sides of another anti-dazzle thin-membrane 2 are in optical glass layer 1
Edge stretch out preset length (such as 30mm), the part extended to outside the edge of optical glass layer 1 is
Film extension 21, Fig. 3 is specifically refer to, film extension 21 is using four sides of the upper surface of optical glass layer 1 as axially
Lower 90 ° of bending, and then film extension 21 is pasted onto on the screen frame 3 of the lower section of optical glass layer 1, so that will
Each side of optical glass layer 1 is fixed on screen frame 3, also optical glass layer 1 is fixed on screen frame 3, shape
Into rear projection screen, as shown in Figure 2.Certainly, rear projection screen is additionally included in curtain between optical glass layer 1 and screen frame 3 and thoroughly
Mirror, anti-dazzle thin-membrane 2 wrap up curtain and lens wherein after the side of optical glass layer 1 is fixedly connected with screen frame 3, the back of the body
Throw screen and be followed successively by anti-dazzle thin-membrane 2, optical glass layer 1, curtain, lens and screen frame 3 from top to bottom, wherein, curtain and lens
It is prior art between optical glass layer 1 and screen frame 3, the application is not described in detail to this.
It should be noted that adhesive-layer of the prior art and connection sheet are replaced using anti-dazzle thin-membrane 2 in the application, and
Optical glass layer 1 is fixedly connected with screen frame 3 by anti-dazzle thin-membrane 2, wherein, anti-dazzle thin-membrane 2 has anti-dazzle light efficiency
Fruit, and the thickness of anti-dazzle thin-membrane 2 is less than the integral thickness of adhesive-layer and connector, so the rear projection screen in the application exists
The black surround formed during splicing is smaller, so as to so that the imaging effect for the rear-projection combination being spliced into gets a promotion, imaging it is complete
Whole property improves.
For example, the thickness of adhesive-layer of the prior art is generally at least 0.3mm, the thickness of connector is generally 0.2mm,
So as to cause the width at least 1mm of the splicing black surround between each rear projection screen in rear-projection combination of the prior art.This

It should also be noted that, the anti-dazzle thin-membrane 2 on the surface of optical glass layer 1 can also be carried out firmly in actual applications
Change is handled, to prevent the surface of anti-dazzle thin-membrane 2 to be scratched.In addition, the rear projection screen of the prior art based on glare proof glass
Reflectivity in the case of big visual angle is higher, and the surface of the rear projection screen in the application is provided with stiffened anti-dazzle thin-membrane 2,
Reflectivity in the case of big visual angle can reduce by more than 50% compared with prior art, so as to understand the rear projection screen in the application
Anti-dazzle light effect is more preferable in the case of big visual angle.
Further, anti-dazzle thin-membrane 2 is based on polyethylene terephthalate (PET) or based on polyvinyl chloride
(PVC) anti-dazzle thin-membrane being made.
It should be noted that the anti-dazzle thin-membrane 2 in the embodiment of the present invention is not limited only to make using above two base material
Form, other materials (for example, other anti-dazzle resin materials) can also be used, it is specific unlimited.It is in addition, reliable to take into account
Property and optical property, the thickness range of the anti-dazzle thin-membrane 2 in the application is preferably 0.125mm~0.25mm, certainly, also not near
It is limited within this range, its specific scope is that its specific thickness value can be determined according to actual conditions.
Further, the thickness range of optical glass layer 1 is preferably 2mm~3mm, but is not limited only to this scope, and it has
Body scope and its specific thickness value can be determined according to actual conditions.
Optionally, preset length ranges preferably from 30mm~40mm, it is of course also possible to be other specific scopes, this
Application is not limited this, can be determined for the concrete numerical value of preset length according to actual conditions.
