Abstract
The invention discloses a projection screen resisting ambient light. The projection screen comprises a base material integrally made of a dark light absorption material and a strengthening component for strengthening and stabilizing the strength of the base material in the horizontal direction and the vertical direction, wherein a large number of micro-convex strips integrally in a sawtooth shape extend on the front face of the base material; a light absorption surface is formed on one side face of each micro-convex strip, and a projection imaging layer is arranged on the other surface of each micro-convex strip. The projection screen resisting ambient light is simple in structure and low in cost; and moreover, the projection screen can resist interference of the ambient light on projection imaging pictures, so that the imaging pictures are clearer, the contrast ratio is higher, the brightness is higher.
Description
Technical field
The invention belongs to projection imaging technology, particularly relate to a kind of projection screen of environment resistant light.
Background technology
Projection screen and the optical projection system application in life very extensive, it is mainly used in the occasions such as large conference room, command and control center, training education structure, meeting room, exhibition room, exhibition center, airport, show window; But in reality, projection screen is under various light environment, and especially in bright ambient light under environment, its surface, by projection of high light, is easy to cause that imaging picture is unintelligible, uneven, dazzle, white seriously vaporific.As everyone knows, if projection screen imaging picture in vain vaporific (picture turns white) serious, greatly can reduce contrast and the brightness of picture, thus it is unclear to be easy to cause user to watch, and then loses itself displaying, demonstration or advertising results.
Summary of the invention
The object of the present invention is to provide a kind of projection screen of environment resistant light, it is effectively resisted surround lighting and disturbs projection imaging picture, thus make that imaging picture is more clear, contrast is higher, brightness is higher, to solve the problems referred to above that in prior art, projection screen exists.
For reaching this object, the present invention by the following technical solutions:
A kind of projection screen of environment resistant light, it comprises the overall base material be made up of dark light absorbent and for strengthening the strengthening part with stabilized base material horizontal and vertical direction intensity, the front of described base material is extended with the micro sand grip of a large amount of overall indentation, a side of described micro sand grip forms extinction face, and another side is provided with projection imaging layer.
Especially, described projection imaging layer is from the lateral disposed inboard of described micro sand grip, and between the inner side edge of described projection imaging layer and the bottom of described micro sand grip, leaving the lower extinction face of the blank screen effect for increasing projection screen that projection imaging layer is not set, the setting in described lower extinction face can improve the light and shade contrast of projection screen projected image.
Especially, the outer end of described micro sand grip is arc surface, is scratched or damages to avoid micro sand grip.
Especially, the side described micro sand grip being arranged projection imaging layer offers the groove of indent, be coated with projection imaging material in described groove and form projection imaging layer, the setting of described groove can improve the flatness of projection imaging layer, improves the image quality of projection screen.
Especially, described strengthening part is be attached at any one of the PET film layer of described substrate backside, carcass, plastic wire compartment or glass layer.
Especially, described strengthening part is any one of the carcass of pre-plugged in described base material, plastic wire compartment or glass layer.
Especially, described channel section is arc-shaped structure.
Especially, described base material just extend described micro sand grip towards horizontal direction.
Beneficial effect of the present invention is, not only structure is simple, cost is low for the projection screen of compared with prior art described environment resistant light; And effectively can resist surround lighting projection imaging picture is disturbed, thus make that imaging picture is more clear, contrast is higher, brightness is higher.The projection quality of projection screen can be improved further by the setting of lower extinction face and groove.

Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
Embodiment one:
Refer to shown in Fig. 1 and Fig. 3, in the present embodiment, a kind of projection screen of environment resistant light comprises the overall base material 1 be made up of black light-absorbing material and enhancement Layer 2, described base material 1 is elastic body, the micro sand grip 3 being just extended with a large amount of overall indentation towards horizontal direction of described base material 1, the equal entirety in cross section of described each micro sand grip 3 is roughly triangle, and a side of described micro sand grip 3 forms extinction face 4, another side is coated with one section of projection imaging layer 5 formed by projection imaging material.Described projection imaging layer 5 is from the lateral disposed inboard of described micro sand grip 3, and between the inner side edge of described projection imaging layer 5 and the bottom of described micro sand grip 3, leave the lower extinction face 6 that projection imaging material is not set, the light and shade contrast of projection screen projected image, for increasing the blank screen effect of projection screen, can be improved in described lower extinction face 6.
The outer end of described micro sand grip 3 is arc surface, is scratched to avoid the outer end of micro sand grip 3 or damages.
The cross section side described micro sand grip 3 being arranged projection imaging layer 5 offering indent is the groove of circular arc, be coated with projection imaging material in described groove and form projection imaging layer 5, the setting of described groove can improve the flatness of the bottom surface of projection imaging layer 5, improves the image quality of projection screen.
Described enhancement Layer 2 is for being attached at any one of the PET film layer at described base material 1 back side, carcass, plastic wire compartment or glass layer.
Embodiment two:
Refer to shown in Fig. 2 and Fig. 3, the present embodiment and the key distinction of embodiment one are that the set-up mode of enhancement Layer 2 is different, other structures are identical, and in the present embodiment, described enhancement Layer 2 is any one of the carcass of pre-plugged in described base material 1, plastic wire compartment or glass layer.
Refer to shown in Fig. 4, during concrete use, described projection screen is vertically arranged, a side because of its micro sand grip 3 is upper extinction face 4, therefore the light irradiated from top is all absorbed (embody rule by extinction face 4, the wide mostly of indoor irradiate from top), the setting in same extinction face 6 at present also absorbs the light of scattering from below to a certain extent, short burnt square projector 7 is positioned over the oblique below of described projection screen, projection imaging layer 5 imaging on the micro sand grip 3 of the image that short burnt square projector 7 projects on projection screen, change the distance between short burnt square projector 7 and described projection screen, the size of picture picture can be changed over.
Above embodiment has just set forth ultimate principle of the present invention and characteristic; the present invention does not limit by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
