The utility model is achieved through the following technical solutions: a kind of line holographic projections film of high contrast, including successively
Imaging film, perforated membrane, the release film of setting are provided with several through-holes on the perforated membrane, and the side of the perforated membrane is provided with
Gum layer, and perforated membrane is connect by gum layer with release film；The gum layer is transparent configuration.
Based on line holographic projections image-forming principle, when starting to work, holographic film can cooperate the presentation content of projection to open up
Show product image data, for contents screen by screen optical treatment, aobvious is especially fine and smooth soft.Line holographic projections are diffraction pattern skills
The application of art possesses 180 ° of absolute angle of visibility and double-sided display performance, and there are all products of vision square clearly to image,
The features such as resistance to bright.When idle, projection film has certain perspectivity, can be convenient the users of projection film two sides into
Row exchange, has preferable practicability.
In order to preferably realize the utility model, it is logical several further, on the perforated membrane have staggeredly been placed equidistant with
Hole.Line holographic projections curtain is one piece of high performance double-sided display screen, it has all products of vision square right in clear imaging, height
The advantages that than spending.The application of hologram (Hologram T.) technology, while by the optical treatment of screen, imaging is especially
Soft exquisiteness.The absolute visible angle and double-sided display performance for possessing 180 ° make projection screen become powerful vision and appreciate and pass
Broadcast tool.When screen does not work, the user that can be convenient projection film two sides is exchanged, and has preferable practicability.
In order to preferably realize the utility model, further, the diameter of the through-hole is 0.8-1.2mm.
In order to preferably realize the utility model, further, the diameter of the through-hole is 0.9mm.When the diameter of through-hole

In order to preferably realize the utility model, further, the release film is transparent configuration, and the gum layer is by rice
Sub- glue or polyacrylic acid ester gum are prepared.
In order to preferably realize the utility model, further, the imaging film is prepared by PET film.
The utility model has the beneficial effects that
(1) losing for projection film is effectively reduced by the setting of release film in the utility model, and the release film can be to throwing
Shadow film plays the role of support protection, and reduction is lost, while can play the role of blocking protection to projection film, has preferable
Practicability.
(2) the utility model effectively provides picture contrast by the setting of perforated membrane, and brightness is high, while reducing nature
Influence of the light to projection film, improves the usage experience of user, has preferable practicability.
(3) the utility model possesses 180 ° of absolute visible angle and double-sided display performance, and projection screen is made to become powerful
Vision is appreciated and spreading tool.When screen does not work, the surface such as mirror is brilliant, very attracts eyeball.
