Abstract

The utility model relates to a three-dimensional displaying film for printed matters, which is essentially composed of a micro lens array film (2) and printed patterns (3). The arranged mode of a micro lens array unit is consistent to mesh dots of the printed matters; the periods are adjacent. The three-dimensional displaying film utilizes the parallactic principle to generate three-dimensional visual effect. Except for essential form, a selectable auxiliary film can also be added; the auxiliary film comprises transparency filling material (1), a printed pattern carrier (4), non-dry adhesive (5) and a protective film (6). Four combined modes of the three-dimensional displaying film are respectively: 2356, 12356, 23456 and 123456. The sectional plane of the micro lens array unit is a convex surface or a concave surface; the horizontal section shape is a circle, a square or a polygon (the number of sides is greater than 5 comprising 5). The thickness of plastic films which comprise the micro lens array can be from 10 microns to 2000 microns according to requirements.

Description

3 D display film for printed articles

The utility model belongs to the 3 D display film material.

Dimension display technologies has been widely used in making the anti-counterfeiting mark and the wrappage of commodity, and wherein laser hologram is comparatively popular, but the observation condition of laser hologram is comparatively harsh, and technology spreads, and its antiforge function is challenged; It is another dimension display technologies that post lens array or micro lens array combine with Micropicture, but the generation of Micropicture is comparatively difficult, and requires strict counterpoint between Micropicture and cylindrical mirror array or the micro lens array, is difficult to realize large-scale production.

The purpose of this utility model provides a kind of film that produces the 3D vision effect on common printed matter, does not need Micropicture, in any angle the 3D vision effect is arranged all, can be mass-produced, and is cheap.

The purpose of this utility model realizes by following proposal:

3 D display film for printed articles is made up of micro lens array film, printed pattern, adhesive sticker, diaphragm.The arrangement mode of micro lens array unit is consistent with the site of printed matter, and the cycle is approaching, utilizes principle of parallax to produce 3D vision.The micro lens array membraneous material can be plastics or resin, and the cycle of the micro lens array on it can be from 10 microns to 500 microns according to the difference of printed matter site.The horizontal cross sectional geometry of micro lens array unit is circular, square, polygon (the limit number contains 5 greater than 5).The section of micro lens array unit is convex surface or incised relief shape, and also available refractive index and the differentiated transparent material of micro lens array membraneous material are filled and led up, and are called not filled-type and filled-type.The thickness that contains the micro lens array film as required can be from 10 microns to 2000 microns, it and printed matter be combined with dual mode: first, micro lens array is molded over the one side of plastics or resin film by the method for mold pressing, printed pattern directly is printed on the another side of plastics or resin film, coat adhesive sticker again and add diaphragm, be called integrated-type; Second; micro lens array is molded over the one side of plastics or resin film by the method for mold pressing or injection moulding, and printed pattern is printed on the carrier thin film (paper, plastics or resin), and both are by the method combination of gluing or deposited film; coat adhesive sticker and add diaphragm, be called compound.During use, throw off diaphragm, expose adhesive sticker, just can be attached on the commodity.

The utility model embodiment provides in conjunction with the accompanying drawings:

Fig. 1 does not fill the sectional structure chart of integrated-type 3 D display film;

Fig. 2, the sectional structure chart of filling integrated-type 3 D display film;

Fig. 3 does not fill the sectional structure chart of compound 3 D display film

Fig. 4 fills the sectional structure chart of compound 3 D display film;

Fig. 5, the unit horizontal cross section is circular microlens array structure figure;

Fig. 6, the unit horizontal cross section is the microlens array structure figure of positive square;

Fig. 7, the unit horizontal cross section is polygonal microlens array structure figure; Sequence number implication among the figure:

1, transparent packing material

2, micro lens array film

3, printed pattern
