The arrangement is characterized in that the lenses (6) and diaphragm openings (4) respectively have an optical axis, and in that the at least one lens arrangement (2, 3) and the at least one diaphragm arrangement (1) are arranged one above another and, in particular, in a manner at a distance from each other such that the optical axes of the lenses (6) and diaphragm openings (4) are aligned and that the lens arrangement (2, 3) and the diaphragm arrangement (1) are fixedly connected to one another.

Description

Flat 3D display unit technical field

The present invention relates to a flat 3D display or constituents. More particularly, it relates to a structure of at least one lens array and at least one aperture array for recording and / or reproduction of three-dimensional real and / or virtual devices.

Moreover, the invention relates to a method for producing such an arrangement.

State of the art

known three-dimensional representations, in which a print with a lens arrangement is provided so that the viewer can view through the lens array to the pressure solely. These lenses are usually arranged as cylindrical lenses in the longitudinal direction over the entire length of the medium and lead depending on the angle to the viewer in the view from different angles also perceives different image information. With such a figure different effects, such as a person can get or different pictures are shown from different angles in different positions or other three-dimensional effects.

A medium for the reproduction of three-dimensional arrays as well as a process for its preparation are known for example from WO 2005/022255.

A detailed representation of the basic optical Procedure DE, for example, to remove 692 22 695 T2.

Summary of the Invention

The object of the present invention is to provide a robust, reliable and easy to set up assembly can be added to the three-dimensional arrays of real and / or virtual nature, and / or play. Here should be possible, in contrast to prior art, a consideration of a wide range of angles, also to allow especially for large displays an observation well at close range. Also, it should be possible to see different two-dimensional images not only from a few discrete different angles, but to look at it from different directions, a three-dimensional image of a three-dimensional Annordnung.

The object is achieved by a structure according to claim 1. Advantageous further developments are shown in claims 2 to 10 degrees.

An inventive structure for recording and / or reproduction of three-dimensional real and / or virtual devices has at least one lens array and at least one aperture array, wherein said at least one aperture arrangement juxtaposed diaphragm recesses and is in particular plate-shaped. The at least one lens array, in particular a plate, includes lenses arranged side by side. The lens arrangements and stop arrangements are arranged one above the other that the lenses with the aperture, in particular their optical axes are aligned. For this purpose the lenses and apertures respectively on optical axes. Optical axes are line-shaped. For example, comprise cylindrical lenses of known arrangements no optical axes.

Advantageously, the aperture of small size than the lenses. The lens assembly and the diaphragm arrangement are firmly connected.

Such an arrangement has the advantage that it is to produce relatively simple and low-profile and still lenses and apertures are each associated in a defined and fixed relationship to each other and can cooperate. This can be in the diaphragm arrangements and / or lens arrays to plates, especially those made of plastic. For example, starting with flat and smooth surfaces of plastic plates can be changed so that lenses or diaphragms are formed here. Alternatively, such arrangements can also be cast, can be prepared in particular by injection molding. The lenses and / or apertures in the lens or bezel assemblies are advantageously symmetrically, in particular in a matrix form are disposed. Advantageously, the lenses and / or apertures are arranged at crossing points crossing at right angles and homogeneously distributed line. In this case, these lines extend in two mutually perpendicular directions, two groups of straight lines thus run in parallel. This arrangement is advantageous compared to a face-centered arrangement, since other elements such as spacers, better and without much loss with respect to the viewing and reproduction quality can be placed.

In an inventive arrangement, in particular, each lens-aperture combination can be assigned to a corresponding film with aligned optical axes, a separate area. In particular, the respective images, which are allocated to the individual lens aperture combination with aligned optical axes or are taken up via these can differ from each other, in particular by a different viewing angle of the images in particular all common scene. In this case, in particular, each individual lens aperture combination with aligned optical axes associated image a complete representation of the, in particular all the images together, be scene from a viewing angle.

This can achieved by the lens-aperture combinations with their associated images, a three-dimensional optical effect, which is largely independent of the viewing angle.

This three-dimensional image impression, for example, can also be perceived by a one-eyed observer. In that he moves, for example, in front of the image, it may consist of various horizontal and vertical observer from different positions and from different remote viewer positions respectively recognize different views of the joint, in particular all the images scenery. Prints cylindrical lens, for example, allow only one direction different views or images, for example, in the horizontal direction.

A projection of objects as a real image in front of the image plane and also the visible objects as a virtual image behind the image plane is also possible with this system. Cylindrical lenses or strip-shaped arranged lenses do not allow this.

A specific method for the exposure of the lens-aperture assemblies associated with each image shows, for example, the DE 102008008232A1.

The plates constituting the lens arrays, may participate in the positions where lenses are to be formed, have projections or depressions, thus forming, for example, convex and / or concave lens surfaces. However, more complex shapes are also conceivable in which, for example, a circumferential, in particular annular recess is introduced and is formed within the same a convex or concave lens surface. It is also conceivable to form a pillar-like elevation, and to provide a convex or concave lens surface on the end face. Lenses and / or apertures are round, in particular formed in the outer contour advantageously circular.

A lens and its extension are defined by the extension of the concave and / or convex lens surfaces.

In an aligned arrangement between lenses and apertures, the lenses are so aligned with the aperture that each lens is associated with at least one aperture. Advantageously, each lens is associated with exactly one aperture and the aperture is formed so that it prevents light transfer between different lenses.

The aperture orders may be formed for example so that, in particular non-transparent or opaque for the light corresponding to the application material with recesses is formed as a diaphragm recesses. however, it is also possible to use transparent material and so form the aperture cutouts that light which passes through the associated lenses and impinges on the boundary of the aperture opening, is totally reflected.

Advantageously, the aperture have a certain thickness of, in particular 100 to 1200 .mu.m, in particular from 300 to 900 .mu.m, in particular of 600 microns. This allows for a sharp separation of the individual lens aperture combination and associated regions on a film.

Aperture recesses are produced for example by stamping from a plate or by injection in an appropriate mold. It is not necessary that the aperture openings are formed as vertical holes of a plate. Rather, it is sufficient if the diaphragm have recesses rising and falling sides and forming at least one aperture recess in the middle. It is particularly advantageous if the aperture recess has a boundary which tapers circumferentially, in particular in the center of the diaphragm thickness, acute. A particularly sharp aperture can be formed.

the compound of the lens and diaphragm arrangements is performed by ultrasonic welding with advantage. Other compounds, for example by adhesive, are conceivable.

If the connection is made by ultrasonic welding, so are advantageously surveys, in particular Verschweißungsdorne, provided that at least partially, particularly terminally, by ultrasonic welding to melt and form the connection. As a rule, also melt areas of the Verschweißungsdornen be welded assembly, opposite the melted on areas of Verschweißungsdorne on.

A compound is advantageously not performed over the entire surface, in particular no compound is carried out in the area of ​​the lens surfaces.

Advantageously, spacing means are provided, which are slightly lower and large surface area, than the Verschweißungsdorne so that when the ultrasonic welding Verschweißungsdorne partially melt and provide a connection, however, the distance is maintained by the spacer means. The spacing means may also provide for a connection by gluing for a defined and uniform distance between the lens and diaphragm arrangements, so as in particular to obtain a predetermined optical path in the overall arrangement.

In the ultrasonic welding of the Verschweißungsdorne can itself serve as a spacer means, by the size of the melting is controlled by the action of the ultrasound and thus a defined distance can be maintained. This can be done by appropriate adjustment of the ultrasonic frequency, amplitude, duration and the contact pressure between the layers to be welded.

At a production by injection molding in particular a hot nozzle in the center of the arrangements is provided which has a diameter of especially 0.5 to 1.5 mm, especially 1 mm. The provision of the hot nozzle at the center of the arrangement obviates the need for separation of existing after the injection molding material residues from the edges of the arrangements particularly when several such devices are arranged side by side in a plane, interfere and can not be removed sufficiently precise usually be become. The diameter of the hot nozzle in the specified range provides the possibility of this in a zone between the functional structures (for example, and in particular the apertures) to arrange.

In particular in the manufacture by injection molding, to be able to remove from a mold lens or diaphragm orders safely and without damage, these advantageously having a relatively low edge length, in particular in the range of 30 - 100 mm, preferably in a form of 30 - 60 x 60 - 80 mm manufactured. Be larger displays required lens arrays or diaphragm arrangements can be laterally joined together side by side. Advantageously, the panel assemblies have a thickness of 100 - 1200 microns, in particular 300 to 900 .mu.m, in particular of 600 microns. Advantageously, the lens arrays having a thickness 1 - 5 mm, in particular 2 - 2,5 mm on. With such lens arrays to flat structures can be formed that can do the job reliably.

The individual lenses or apertures have a center distance of advantageously 1-4 mm, in particular from 2 to 3 mm, particularly 2 mm. At such a distance can be for single picture thus realize sufficiently large, but as close as possible to pack also sufficiently small lenses for the resolution of the whole image and the best possible image or recording.

The apertures advantageously have a diameter of 0.5 to 2 mm, preferably 1 to 1.6 mm, especially 1.3 mm. The lenses advantageously have a diameter of 1 to 3 mm, in particular 1, 5 to 2 mm, particularly of 1.8 mm. Advantageously, the lens systems or diaphragm orders are produced in card size and thus have an edge length of about 52 x 76 mm. Advantageously 26 x 38 are provided diaphragms or lenses.

Advantageously, the structure according to the invention in particular to the lens arrangements and stop arrangements centering means for aligning. Advantageously, the panel assemblies thereby Zentriererhebungen, such as in particular conically tapered extending pins, and the lens arrays corresponding to Zentriersenkungen. Such centering centering can be achieved in the assembly of lens arrangements and stop arrangements above the other. This an aligned alignment is possible and can the association between lenses and apertures, and thus the functioning of the system are backed up easily.

Also conical and the aperture directed towards the lens surfaces that are partially received in the aperture or their oblique limitation, are Justagehilfsmittel. Thereby, the assembling of a lower accuracy carried as is to be achieved in the assembly, since the lens assemblies and the panel assemblies to thereby centering upon approach even if a comparatively coarse approximation alignment is given. A finer centering can be effected by the actual centering.

Advantageously, the centering means are at least partially conical. This makes them the self-adjusting Justagehilfsmittel and allow a relatively imprecise joining up and high accuracy in the structure.

Advantageously, as many centering means are provided for the arrangement of the lens arrays to be arranged and diaphragm arrangements is overdetermined. In this case, at least some of the centering means, in particular, all arranged on one of the parts to be joined centering means are designed to be elastically deformable. In particular, the Zentriererhebungen are elastically deformable constructed and arranged with advantage in total on one of the parts to be joined, the or the further parts advantageously contain the Zentriersenkungen. This error in production or the alignment of the elements in the middle can be reduced so that you can work with comparatively large manufacturing tolerances, without having to sacrifice an accurate and sufficient centering. In particular, exactly eight, and eight Zentriererhebungen Zentriersenkungen be advantageously per diaphragm arrangement or lens arrangement, at least eight, are provided. For a defined arrangement, however, two such elements per array would suffice. Thus, an arrangement with eight centering is clearly overdetermined. This results in a particularly accurate alignment.

Even when providing a plurality of panel assemblies next to each other or lens arrays next to each other in order to realize a larger structure, such centering means are advantageous. in addition to the alignment of aperture arrays on lens arrays They also allow an alignment and stabilization of the laterally adjacent panel assemblies and adjacent lens arrangements. Advantageously eight centering per lens or diaphragm device are further provided. If the individual elements are arranged so arranged that the layer of the lens assemblies with respect to the layer of the panel assemblies laterally offset, thereby a reliable and durable joining structure can be ensured. Here, a in both directions of the layers of phase-shifted by half a side length placing is particularly advantageous. Overdetermination arises even at two centering per plate when offset laterally at least two, in particular at least three layers of lens arrays and / or panel assemblies are placed one above the other and each pair of plates against each other is centered by two centering per plate.

Are advantageously spacing means according to claim 3 to the panel assemblies and / or lens arrays, in particular, provided on both sides of the panel assemblies. Such spacing means a minimum distance between aperture configurations and lens arrangements can be secured and evenly maintained. If the arrangements then pressed against each other, not only a minimum distance, but also a defined distance is ensured. This is advantageous, for example for adjusting the optical distances. Moreover, in providing a plurality of spacing means also a planar or parallel application of lens arrangements and stop arrangements may be secured to each other.

Spacing means can be realized by simple distance elevations or spikes distance. The spacing means are, in particular 10 to 20 .mu.m, in particular 15 microns high. They may be provided in almost any desired arrangement on the individual lens assemblies and / or stop arrangements and in particular perpendicularly protrude out from the plane of a lens or diaphragm device, the lenses or diaphragms are in particular parallel to the optical axes aligned.

Advantageously, an outer, in particular external, lens assembly according to claim 4 on its outward facing surface of concave lens surfaces. Under an external lens array means a lens assembly, which is seen from an adjacent aperture arrangement of the observer or to the object to be picked out. An outer lens assembly is one which represents the outer boundary of the structure to the viewer or object to be picked out. In principle, any number of lens arrays and aperture arrays may stacked and bonded together. Advantageously, however, this case has an outer this lens assemblies, in particular an outer lens array on its outward facing surface of concave lens surfaces. This leads to a particularly advantageous imaging and reproduction. Advantageously, a lens arrangement on the side facing the diaphragm surface in a convex lens surfaces. This is particularly advantageous for imaging. In addition, the convex lens surfaces can at least partially extend obliquely in the depth of the aperture arrangement in guided diaphragm edges. This allows a particularly space-saving arrangement in which the lens arrays extend partially into the aperture and orders already characterized a certain alignment and centering of the two arrangements can be achieved.

Advantageously, an inner lens arrangement, in particular an innermost lens array, obliquely inclined according to claim 5 on an inwardly facing surface, just extending lens surfaces. Under an inner lens array means a lens assembly, which is seen from an adjacent aperture arrangement of the film toward or away from the viewer and object to be photographed. An innermost lens arrangement is a lens arrangement, which is furthest from the viewer to be recorded or object away, or the closest to the film. Such oblique lens surfaces have the advantage that with a bonding an air-bubble-free at the point of lenses adhesive bond can be easily ensured. These are advantageously provided between the individual lenses adhesive reservoir. In these reservoirs can flow when pressing the inclined surfaces extruded adhesive. The adhesive should have a corresponding to the material of the lens arrangement of the refractive index, one or no more than 10%, preferably not more than 2% deviate from this refractive index in order to obtain at this interface no unwanted optical refraction. Under an oblique verlaufenen lens surface one against the plane of the lens arrangement, in particular against a plane perpendicular to the optical axes of the lenses is to be understood inclined lens surface be inclined in particular by more than 0 ° and less than 90 °, in particular 25 to 65 ° can. They advantageously extend over a height of 20 to 100 .mu.m, in particular 40 to 60 .mu.m, more preferably about 50 .mu.m.

Such an arrangement may in particular by initially columnar, particularly in cross-section circular, then be realized by a plate with an excellent and obliquely disposed straight lens surface final lenses. Between the columnar protrusions then adjacent adhesive reservoirs are formed, in which the adhesive can be added after the displacement. Also, air bubbles are moved to the reservoir and can remain there without that they would interfere with the imaging properties of the system.

Such an arrangement enables a particularly reliable, free of air bubbles and compact arrangement or application to another material, for example a substrate or a film.

Advantageously, the structure on two lens assemblies and a diaphragm arrangement. The baffle arrangement between the lens arrangements is arranged. Advantageously, lens arrangements according to claim 4 and claim 5 are provided. Advantageously, therefore have the lens assemblies for diaphragm towards convex lens surfaces which advantageously at least partly project into the panel assembly. Advantageously, an outwardly lens assembly on an outer surface having concave lens surfaces. Advantageously, the other lens assembly with its directed to the film surface obliquely inclined straight lens surfaces. Such an arrangement is particularly space-saving, efficient and provides good image or playback.

Such an arrangement and such a structure can be applied for example to a film or first a carrier substance or a carrier material. Here, the carrier substance or the carrier material for the light, in particular visible, is formed for the structure or used transparent.

This creates a solid structure that can meet the requirements very well generally.

, A plurality of lens assemblies are advantageously especially when spatially extended displays are needed, arranged side by side and a plurality of panel assemblies side by side. The lens systems are advantageously offset from the diaphragm arrangements. Particularly preferred is a by one half the edge length in both directions of the lens arrays or diaphragm assemblies staggered arrangement. Such an arrangement allows a particularly great stability between the individual layers, as well as a large-scale compliance with the grid positions by the lenses and apertures.

Advantageously, it is a structure according to claim 7, in particular processes a time-shifted structure such that the panel assemblies are shortened so that they form with the lens arrangements a flush outer edge of the structure. When the panel assemblies or lens arrays tiled or in particular in two directions arranged around half an edge length of phase, they are not flush with the same size. Advantageously, however, more panel assemblies are used as lens assemblies, so that the diaphragm arrangements survive, and these are then reduced accordingly. This is advantageous because diaphragm arrangements can be shortened easily and without occurring later drawbacks. In particular, changes such as deformation effect, by shortening the diaphragm arrangements less than in the lens arrays. In addition, diaphragm arrangements usually thinner and therefore are easier to cut with less material loss.

Advantageously have juxtaposed panel assemblies according to claim 9 at each adjacent side or end surfaces thus formed structures that after joining the panel assemblies, in particular with a remaining distance, in particular from 10 to 100 microns, preferably 40 - 60 microns, on the no addition, in particular transversely to the plane of the diaphragm arrangement, ie parallel to the optical axes of the aperture extending straight gap between the two half-spaces remaining on both sides of the panel assemblies. Then no light between them can pass at the joining line. In particular, the side surfaces are formed to a stepwise manner. but also training as a tongue and groove or hook shape are possible, production of technically complex. Such a configuration provides a reliable shutter layer safely. In particular, the steps are formed so that they perpendicular to the extension of the panel assembly, in particular to the optical axes of the diaphragm parallel edge having an extending over the half of the thickness of the panel assembly, in particular plus game, in particular of 1 - 10 microns, extends. This is followed by a pre- or perpendicular to return, in particular with a length of 25 to 250 .mu.m, in particular from 80 to 120 .mu.m, in particular from 100 microns to. This is followed by a parallel to the first edge edge through the remaining thickness of the diaphragm arrangement connects. The desired distance between individual adjacent panel assemblies is advantageously from 20 to 100 .mu.m, in particular 40 - 60 microns, preferably 50 microns. The target distance is achieved in the theoretical means, but not necessarily maintained between individual diaphragm arrangements since the deformation of deformable centering means a deviation is desired at the time in order to compensate for production inaccuracies.

Arranging with remaining distance is particularly advantageous when elastically deforming centering, since then caused by the elastic deformation movements of the individual assemblies remain against one another possible. This allows greater fault tolerance in a still reliably joinable structure or display.

Advantageously, the structure is applied to a carrier plate. The support plate is optically transparent to the appropriate light. Advantageously, a film, particularly a multi-layer paint film, in particular an inversely constructed multi-layer color film is disposed on the side facing away from the lens arrays side of the carrier plate.
