Photosphere 50.The microprism grating curtain for being applicable to strong light environment of the utility model can be used for rear projection screen.
As shown in FIG. 1 to 3, the substrate layer 10 is transparent, and is made of translucent material, for example, its can by glass,
The materials such as PC, PET are made.
The light-absorption layer 40 is set on a side surface of the substrate layer 10, is used to absorb ambient light.In the present embodiment,
The light-absorption layer 40 is equipped with several black transparent microballons 41.41 uniform intervals of the black transparent microballon setting, so that phase
Transmission region is formed between adjacent two black transparent microballons 41, so that projection ray can pass through.When it is implemented, the black
Transparent microballon 41 with coating process coating on the surface of the substrate layer 10, e.g., by black transparent microballon 41 mix coating or
In, it is then whole to be coated on the surface of the substrate layer 10, the light-absorption layer with 41 structure of black transparent microballon can be formed
40.Since the black transparent microballon 41 is in black, thus it can reduce the reflection to ambient light so that main ambient light is not
It is reflected and is predominantly absorbed, and then reduce influence of the ambient light to projection.And since the black transparent microballon 41 is that interval is set
It sets, thus projection ray can be still imaged across the transmission region in the light-absorption layer.The black transparent microballon
41 grain size can be set as desired, and the present embodiment does not limit its size.
As shown in FIG. 1 to 3, the imaging layer 20 makes human eye watch on the screen for being transmitted to projection ray
To projected picture.The imaging layer 20 can be made of trnaslucent materials, as PVC material is made.
The lens jacket 30 is for reflecting projection ray so that projection ray reflects forward and is directed to imaging
Layer 20.The lens jacket 30 includes several cylindrical lenses 31 and several terrace with edge lens 32.The cylindrical lens 31 and the terrace with edge
Lens 32 are transparent.Horizontal direction of the cylindrical lens 31 with the terrace with edge lens 32 respectively along the imaging layer 20 is set
It sets, the lateral length of development length and the imaging layer 20 matches.The cylindrical lens 31 and the terrace with edge lens 32 are flat
Row.The terrace with edge lens 32 are arranged with 31 uniform intervals of the cylindrical lens, in the present embodiment, in adjacent two rows of terrace with edge lens 32
Between be respectively equipped with row's cylindrical lens 31, be respectively equipped with row's terrace with edge lens 32, phase between adjacent two rows of cylindrical lenses 31
Spaced apart between adjacent two rows of terrace with edge lens 32 and cylindrical lens 31, the distance at interval can be set as desired.
As shown in FIG. 1 to 3, the cylindrical lens 31 is piano convex cylindrical lens 31, and whole is in strip, deviates from institute
The side surface for stating imaging layer 20 is in piano convex cylindrical shape, remaining both side surface is in planar.In the present embodiment, the cylinder is saturating
The plane surface of the opposite sides of mirror 31 is vertical with the imaging layer 20.
As shown in FIG. 1 to 3, it is in strip that the terrace with edge lens 32 are whole, and often row's terrace with edge lens 32 respectively include several
A terrace with edge lens unit 321.In the present embodiment, the terrace with edge lens unit 321 is positive truncated rectangular pyramids lens 32, that is, it has 5
Optical surface can reflect projection ray.Between each terrace with edge lens unit 321 of same row, both it can be connected together,
It also can uniform intervals.In the present embodiment, be located at same row each terrace with edge lens unit 321 between uniform intervals, between be spaced
Distance, can be set as desired.
As shown in FIG. 1 to 3, the height of the cylindrical lens 31 is more than the height of the terrace with edge lens 32.
The cylindrical lens 31 can be formed with the terrace with edge lens 32 by well known technique, and the utility model does not limit it
Technique.
Further, it may also include anti-dazzle photosphere 50.The anti-dazzle photosphere 50 be set to the light-absorption layer 40 and base material
On 10 opposite another side surface of layer.The anti-dazzle photosphere 50 is hyaline layer, and surface is equipped with several subtle raised particles,
The surface has certain roughness, is used to carry out a degree of diffusing reflection to light, so that it has anti-dazzle
Effect, and play increase projection screen angular field of view effect.
Thereby, the microprism grating curtain for being applicable to strong light environment of the utility model is just formd, includes saturating successively
Mirror layer 30, imaging layer 20, substrate layer 10, light-absorption layer 40 and anti-dazzle photosphere 50, the lens jacket 30 are equipped with spaced cylinder
Lens 31 and terrace with edge lens 32, the light-absorption layer 40 are equipped with black transparent microballon 41 for absorbing ambient light.The utility model
The microprism grating curtain for being applicable to strong light environment can be used as rear projection screen, in use, the anti-dazzle photosphere 50 is towards sight
Many sides, the lens jacket 30 are away from the side of spectators, and projection device 60 is set to the rear of the lens jacket 30.Projection is set
Standby 60 projection rays sent out initially enter lens jacket 30, entered to after the refraction of lens jacket 30 imaging layer 20 carry out at
Picture.Since imaging layer 20 is translucent, substrate layer 10 is transparence, has transmission region, therefore, Yong Hucong in light-absorption layer 40
The side of light-absorption layer 40 can see the projected picture on imaging layer 20.And ambient light be usually located at it is opposite with projection device 60
Side, the i.e. side towards light-absorption layer 40, when ambient light is incident upon light-absorption layer 40, the black transparent microballon 41 is not to this
Ambient light is reflected, so that the ambient light does not enter human eye simultaneously with projection ray, to reduce ambient light to projection
The influence of picture so that user sees it can be seen that the higher projected picture of contrast after projection ray enters human eye.Due to the suction
Black transparent microballon 41 in photosphere 40 be it is spaced, thus black transparent microballon 41 can reduce the reflection to ambient light and
The interference of ambient light is reduced, the transmission region between black transparent microballon 41 can be such that projection ray is projected across without obstruction, because
And it can not influence back projection light while absorbing ambient light, to which the contrast of projected picture can be improved so that it can
Suitable for strong light environment.
Although being disclosed to the utility model by above example, the scope of the utility model is not limited to
In this, under conditions of conceiving without departing from the utility model, it is similar that above each component can use technical field personnel to understand
Or equivalent element is replaced.
