Abstract
Combined film of micro lens and micro figure comprising micro lens array layer, plastic base layer and micro figure layer combined and closed each other, and the micro figure layer has structure matching that of the micro lens array. The materials are combined in one of the three modes: lens-plastic figure, lens-figure-plastic and lens-plastic-figure-plastic. There are three micro lens units including square, hexagon and circular forms, and there are the three micro lens arranging modes including square, hexagonal and circular edge contact ones. The film has horizontal parallax and vertical parallax maintained simultaneously, exhibitis three-dimensional figure in any lighting conditions in large view angle, and is not easy to counterfeit.
Description
The invention belongs to the false proof or wrappage that three-dimensional picture shows.
At present, be used for the false proof or packaging film material that three-dimensional picture shows on the market laser hologram film is arranged.Laser holography has been widely used in 3-D display, as existing laser hologram trade mark and plastic package material.Laser hologram has that viewing angle is less, color only for iris, need certain deficiencies such as Observational Techniques, and because of technological diffusion and hologram are easily turned over mould, thereby easily copied, pseudo-product time and again appear on the market, remain to be sought new anti-fake material.
The purpose of this invention is to provide a kind of combined micro lens and micro figure film, make it can keep horizontal parallax and vertical parallax simultaneously, can show three-dimensional picture under any luminous environment, viewing angle is big, need not the special survey skill, and difficult quilt is copied.
The objective of the invention is to realize by following proposal.
Combined micro lens and micro figure film is close to by micro lens array layer, plastic base bottom and Micropicture layer and is combined, and wherein, the structure of Micropicture and the structure of micro lens array are complementary.The lenticule unit of micro lens array layer has three kinds, promptly square lens, hexagonal lenses or round lens, and its lenticule arrangement mode also has three kinds accordingly, i.e. square arrangement mode, hexagonal array mode or circular edge contact arrangement mode.The array mode of three kinds of materials that builtup film is used has three kinds: the first, and micro lens array layer, plastic base bottom, Micropicture layer; The second, micro lens array layer, Micropicture layer, plastic base bottom; The 3rd, micro lens array layer, plastic base bottom, Micropicture layer, plastic base bottom.Be called builtup film I, builtup film II, builtup film III successively.
Embodiment of the invention accompanying drawings provides.

Fig. 2, builtup film II sectional structure chart;
Fig. 3, builtup film III sectional structure chart;
Fig. 4, the arrangement mode synoptic diagram of square microlens array;
Fig. 5, the arrangement mode synoptic diagram of sexangle micro lens array;
Fig. 6, the edge contact arrangement mode synoptic diagram of circular microlens array.
Sequence number implication among the figure: 1, micro lens array layer, 2, the plastic base bottom, 3, the Micropicture layer, 4, square lens unit, 5, the hexagonal lenses unit, 6, the round lens unit.
Embodiment 1: builtup film I (Fig. 1).
Builtup film is formed by three layers.The superiors are micro lens array layers 1 that the transparent PVC material is made.Wherein, the lenticule unit is the square lens 4 of 0.25mm * 0.25mm, and the single-element lens numerical aperture is 0.01, and array adopts closely arrangement mode (Fig. 4) of square.The middle layer is that thickness is 2mm with the plastic base bottom 2 of transparent PVC material conduct.Orlop is the Micropicture layer 3 of the plastic base bottom 2PVC material lower surface in the middle of directly printing is attached to.The structure of Micropicture and the structure matching of micro lens array.Present embodiment adopts the lenticule of low numerical aperture and the middle layer (2mm) of higher caliper; Can obtain dynamic three-dimensional picture, that is, along with the motion of observer's head, three-dimensional picture can be given birth to corresponding variation.
Embodiment 2: builtup film II (Fig. 2).
Builtup film II is made up of trilaminate material.The superiors are the micro lens array layers 1 with the transparent PVC material.The hexagonal lenses 5 that its lenticule unit is 0.1mm * 0.1mm, single-element lens numerical aperture are 0.1, and array adopts the tight arrangement mode of sexangle (Fig. 5).The centre is directly to print attached to the Micropicture layer 3 on the upper surface of the PVC of lower floor film, and Micropicture and micro lens array directly paste mutually, the structure matching of its structure and micro lens array.Orlop is the plastic base bottom 2 with the conduct of opaque PVC material, and thickness is 0.2mm.The present embodiment lenticule has higher numerical aperture, can obtain real 3D vision, and three-dimensional picture does not change with the motion of observer's head.
Embodiment 3: builtup film III (Fig. 3).
Builtup film III is made up of trilaminate material.The superiors adopt the micro lens array layer 1 of transparent PVC material, the round lens 6 that its lenticule unit is 0.25mm * 0.25mm, and the single-element lens numerical aperture is 0.1, array is taked circular edge contact arrangement mode (Fig. 6).The middle layer is the plastic base bottom 2 with the conduct of transparent PVC material, and thickness is 1.25mm.Orlop is for directly being recorded in the Micropicture layer 3 on the high resolution material (carrier is a PVC plastic base bottom 2).This mode can obtain the three-dimensional picture of high definition.
The present invention adopts binary and continuous micro relief profile manufacturing technology, produce the continuous micro relief profile of micro lens array on photoetching material (as photoresist) surface, method with electrodeposit or dry etching is transferred to (as the nickel plate) on other material that can be used for mold pressing with the embossment structure of lens, through duplicate with layout after obtain making micro lens array template, can on plastics, hot pressing go out micro lens array with mould pressing method.Print out according to design of user's needs and the Micropicture that is complementary with the upper strata micro lens array in the one side of plastic sheeting with graphic printing equipment, also available other method (respectively utilizing lenticule directly to take a picture) produces Micropicture.Builtup film of the present invention can be widely used as various trade marks and false proof, wrappage.
The present invention has following features:
1, kept simultaneously horizontal parallax and vertical parallax.
2, can under any luminous environment, show 3-D graphic.
3, viewing angle is big, does not need special Observational Techniques.
4, the technology novelty is difficult for being forged.
Claims (4)
1, combined micro lens and micro figure film is characterized in that it is close to by micro lens array layer, plastic base bottom and Micropicture layer to combine that the structure of Micropicture and the structure of micro lens array are complementary.
2, builtup film according to claim 1, the lenticule unit that it is characterized in that said micro lens array layer is square lens, hexagonal lenses or round lens, and its lenticule arrangement mode should be square arrangement mode, hexagonal array mode or circular edge contact arrangement mode mutually.
