POSITIONING AND ALIGNMENT DEVICE FOR TILED DISPLAYS Field of the Invention The present invention relates to the field of tiled displays and their installation and production. Background. Large-scale displays that are used at public events, such as football matches, consist of a number of sub-images that are displayed on tiles, so-called "tiles". Each separate image is displayed, assuming that the tiles have a very specific geographical relationship to each other. This geographic ratio must be known and accurate, so that the sub-images start and end at the correct positions and leave sufficient space between the tiles. The problem of aligning the tiles in a tiled display is well known in the art. Aligning the tiles is important to prevent visual artifacts from appearing in the images displayed on the tiled display. The tiles must not only be parallel to each other, but the space, the joint, must be equally wide throughout the tiled display. The width of the joint can vary depending on the position on the tiled display due to, for example, deviations (tolerances) in the dimensions of the profiles or beams that are joined together to form a bearing structure for the tiles of the tiled display. Tiles can, for example, be attached to the support structure by means of bolts and nuts. Deviations with regard to the position of the holes in which the bolts must engage can also contribute to the variation in the joints. It is possible that the beams of the bearing structure are not perfectly aligned, which will influence the alignment of the tiles. This will also contribute to variations in the width of the joint on one side of the same tile. Although there are various solutions for aligning the tiles of a tiled display, they either require complicated mechanical connections between tiles, such as in US 8,384,616 B2, or are time-consuming to install and set up. Summary of the invention. The inventors have come to the conclusion that a solution is required that does not require complicated additional hardware, that is capable of accommodating the tolerances (deviations) of a "normal" standard support structure with the desired accuracy and that, for example, can be applied with an existing support structure with a minimum of adjustment. In claims 1 to 16, an arrangement of two or more adjacent displaytiles according to embodiments of the present invention is disclosed, wherein each dependent claim is a separate embodiment of the present invention. In claims 17 and 18, a method for producing an arrangement of two or more adjacent displaytiles according to embodiments of the present invention is disclosed. In claims 19 and 20, a positioning and alignment device according to embodiments of the present invention is disclosed, wherein each independent claim is a separate embodiment of the present invention. In claim 21, a tiled display according to embodiments of the present invention is disclosed. In one aspect of the present invention, use is made of a positioning device and an attachment means to fix the relative position of two or more adjacent tiles on a tiled display and to provide an alignment. Fixing (securing) the relative position of two adjacent display tiles will facilitate the alignment of tiles in tiled displays, where the joint between tiles should be as even as possible, and thus avoid introducing erroneous alignments and their accompanying visual artifacts. . According to an aspect of the present invention, a positioning device is provided that allows coupling thereof with at least two tiles of a tiled display. The display tiles are often rectangular in shape and the positioning device is located at a corner of the tile. Once coupled, the positioning device and the at least two tiles will behave as a solid body, i.e. the relative position of the tiles and the positioning device relative to each other will be fixed. When the positioning device is used, e.g. to merge the tiles and form a tiled display, it may possibly deform elastically. The elastic deformation of the positioning device can change the relative position of one of the at least two tiles relative to the other tile that is coupled to the positioning device. To achieve this, the positioning device can be made of an elastic material, such as a metal or a plastic. The means for coupling the tiles to the positioning device can also be subject to play. The play can also cause a change in the relative position of one or more of the at least two tiles relative to the other tiles that are coupled to the positioning device. According to a further aspect of the invention, the material of the positioning device, the geometry of the positioning device, the material of the means for coupling the positioning device to the tiles and the geometry of these means are selected such that the change in relative position of the tiles is negligible in relation to each other compared to the tolerances (deviations) that affect the tiled display and that must be compensated. In particular, the geometry and materials of the means for coupling at least two tiles to the positioning device are chosen to limit the change in relative position of the tiles coupled to the positioning device to 10% of the tolerances of the tiled display or less than 10% of those tolerances. According to a further aspect of the invention, a tile can be coupled to the positioning device by at least one pin and aperture combination or pair. The opening can be a blind hole or through hole. The pin can be called a positioning pin. With one option the pin can be attached to the tile. The pin engages an opening in the positioning device that can be referred to as a positioning opening. The positioning opening can be a blind hole or through hole. A less preferred arrangement is that in which the pin is fixed on the positioning device and the hole is in the tile. The positioning device preferably has at least one positioning opening per tile which ensures coupling to the positioning device. When a single pin or pin and aperture combination is used to couple a tile to the positioning device, the angular position of the tile relative to the positioning device will be subject to great fluctuations during handling, unless the friction between the positioning pin and the positioning opening is large enough to prevent this. The friction required to maintain the relative displacements and of the tiles coupled to the positioning device at or below 10% of the tolerances that affect the tiled display can have some disadvantages. For example, it may be difficult to place the positioning pin in the positioning opening or to remove the positioning pin. This can affect the speed at which the tiled display is assembled and also the productivity of those who assemble the tiled display. Therefore, according to a further aspect of the invention, a tile is coupled to the positioning device by two or two pin and opening combinations, e.g. two positioning pins which engage in two positioning openings in the positioning device. In that case, the positioning device has two positioning openings per tile to be coupled to the positioning device. Coupling a tile to a positioning device by means of two pin and opening combinations, e.g. two positioning pins which engage in two positioning openings, is advantageous for the extent or amplitude of the rotation of a tile relative to the positioning device and the other to the positioning device tiles and to keep the resulting change in relative positions at or below 10% of the tolerances of the tiled display and at the same time the force required to place a positioning pin in a positioning opening or to remove a positioning pin placed in a positioning opening on a to maintain a comfortable level. If the play of the two positioning pins of a tile in the positioning openings of the positioning device is negligible, it can be considered in a first approximation that the angular position of the tile relative to the positioning device is fixed. In order to further facilitate the correct alignment of the tiles and their attachment to the support structure, the positioning device can be attached to the support structure by means of a fixing means. For at least some of the tolerances to be compensated, it will be necessary to adjust the position of the fastener. The fastener can be a second pin and opening combination or pair. According to a further aspect of the invention, the fixing means for fixing the positioning device to the support structure can accommodate displacements of the tiles in the plane of the tiled display. The maximum amplitude of the displacements allowed by the fastener is of the same order of magnitude as that of the tolerances to be compensated. According to an aspect of the present invention, the fastener is at least one fastener comprising an elastic material, such as rubber, for clampingly securing the positioning device to a support structure. In a further aspect of the invention, the fixing means, e.g. the rubber fixing element, is arranged clampingly in an opening in the positioning device and an underlying opening in the support structure. A less preferred embodiment is where the positioning device has a pin with rubber which is fixed to the positioning device and can be driven through an opening in the support structure. Also in a less preferred embodiment, the support structure has a pin with rubber that is attached to the support structure and can be driven through an opening in the positioning device. When a single fastener, e.g., a single rubber fastener, is used to fasten the positioning device to the support structure, the amplitude of the rotation of the positioning device around the fastener, e.g., the rubber fastener, is likely to be a problem (e.g. may wish the positioning device to help align the tiles not only with respect to each other, but also, to a certain extent, with respect to the support structure. For this purpose, the positioning device can be fastened with the aid of more than one fastening means, e.g. rubber fastening elements. Two fasteners, e.g. two rubber fasteners, to fasten the positioning device to the support structure, seem a good compromise between compliance and accuracy. In a further aspect of the invention, the positioning device may be in the form of a series of radially extending arms, e.g. a cross with four arms. Other numbers of radially extending arms can be used, e.g. 8 arms. Two diametrically opposite arms can each contain a hole of the second pin and hole combination. The bridle arms of the positioning device may contain a hole of the first pin and hole combination. Brief description of the Figures.

The present invention will be described with the aid of specific embodiments and with reference to certain drawings, but the invention is not limited thereto, but only by the claims. The described drawings are only schematic and not restrictive. In the drawings, the dimensions of some elements for illustrative purposes may be exaggerated and not drawn to scale. Where the term "comprising" is used in the present description and claims, this does not exclude other elements or steps. Where an indefinite or definite article is used to refer to a singular noun, e.g. "a" or "de", "it", this also includes a plural of that noun, unless specifically stated otherwise. The term "comprising" as used in the claims is not to be construed as being limited to the means mentioned thereafter; other elements or steps are therefore not excluded. Furthermore, the terms first, second, third and the like in the description and in the claims are used to distinguish between similar elements and not necessarily to indicate a sequential or chronological order. It is to be understood that the terms used in this manner are interchangeable under proper conditions and that the embodiments of the invention described herein may function in a different order from that described or depicted herein. In addition, the terms top, bottom, horizontal, vertical and the like in the description and claims are commonly used to indicate a horizontally laid element unless it is assigned a different meaning. In the drawings, the same reference numerals denote similar parts and a reference numeral occurring in more than one figure always denotes the same element. In the following embodiments, it will be described which openings or holes are used to fix the structure by means of fixing elements, such as pins or bolts. In all embodiments, it is acceptable, but it is often less preferred to swap the positions of the openings and pins. In other words, a mechanical reversal is possible in any case. It may also be acceptable in some embodiments to use a fastening element that is generally in the form of a rivet that passes through two holes. The term rivet includes elements that include rubber that has an enlarged head at each end that functions as the flattened heads of a rivet to secure the rubber rivet in place. In a first embodiment, the positioning device has radially extending arms, such as four arms which run equally spaced in the form of a cross with means for attaching it to a support structure and with means for attaching it to at least two tiles of the tiled display to link. The means for attaching the positioning device, e.g. cross, to a support structure is preferably sufficiently elastic to allow movement of the positioning device, e.g. cross, within the plane of the tiled display when a force is exerted on the positioning device, e.g. the cross. By sufficiently elastic it is meant that the amplitude of the movement of the positioning device, e.g. the cross, will have the same order of magnitude as the tolerance (deviation) that influences the tiled display and in particular the position of a tile on the tiled display and in particular the relative position of the tiles of the tiled display. For example, if the cumulated tolerances that affect the tiled display (e.g., the tolerance for the dimensions of the element of the support structure, for the angles between element of the support structure, for the dimensions of the tiles, the position of means such as holes for fixing the elements of the support structure, position of means such as holes for fixing the positioning device, e.g. the cross itself, to the support structure ...) are up to 5 mm, then the amplitude of the elastic deformation of the means for applying the positioning device, e.g. the crotch, to the support structure, for example, be 5 mm or more when a force is exerted on the positioning device, e.g. crotch, within the plane of the tiled display. The amplitude of the force to cause a displacement of 5 mm or more is preferably the force that a field technician can repeatedly exert over the entire assembly of the tiled display, e.g. 100 N (Newtons) and preferably less than 100 N, e.g. between 10 N and 50 N. The positioning device, e.g. cross 1, in Figure 1a (top view) and 1b (cross-section) is attached to a support structure 12 by means of at least one fixing means, such as rubber fixing element 2, which is clamped through an opening 3 in the positioning device, e.g. cross 1, and into an underlying opening 4 in the support structure 12, as shown in Figures 2a and b. The positioning is more accurate if the positioning device, e.g. cross, is attached by two or more fasteners, e.g. rubber fasteners (2, 5) that are clamped through openings 3 and 6 in the positioning device, e.g. cross 1. Two fasteners, e.g. rubber fasteners, to attach the positioning device, e.g. cross 1, to the support structure 12 seem to be a good compromise between ease of use and accuracy. A single fastener, e.g., a single fastener, still allows rotation of the positioning device, e.g., cross, in the plane of the tiled display, while more than two fasteners, e.g., fasteners, impose additional restrictions on the movement of the positioning device. , e.g., cross, within the plane of the tiled display. In a specific embodiment, the two openings 3 and 6 within which the two alignment and fastening means, e.g. rubber fastening elements 2 and 3, are clamped, are spaced apart on a line passing through the center of the positioning device, e.g. cross 1 , is going. In accordance with an embodiment, a first opening 3 can be close to the end of a first arm 7 of the cross 1 and a second opening 6 can be close to the end of a second arm 8 of the cross 1. The first arm 7 and the second arm 8 are in symmetrical positions with respect to the center of the cross 1. The rubber fastening elements can be rubber sleeves that surround a bolt or screw or can be rubber-lined rubber cylinders with a diameter slightly larger than the diameter of the openings 3 and 6 and 2 and 4, so that they are clamping not only in openings 3 and 6, but can also be provided in openings 2 and 4. Alternatively, the rubber mounting elements may have a more complex geometry, as shown in Figure 2b. The fastening element of Figure 2b must be driven through the openings 3 and 4, which is possible thanks to the properties of rubber. Once the "head" of the fastening element has passed through the opening 4, it returns to its original shape, so that the rubber fastening element can no longer withdraw from the opening 4. In Figure 2a, the rubber fixing element 2 is shown as a rubber cylinder with a cap and the rubber fixing element 5 is shown as a bolt in a rubber sleeve. Other elastic fastening elements are possible, as long as they allow to move the positioning device, for example the cross 1, within the plane of the tiled display, the amplitude of the movement being of the same order of magnitude as the tolerances that influence the relative position of two adjacent displaytiles. Each arm of the positioning device, e.g. cross 1, has two positioning openings (e.g. 9 and 10 on arm 7). The positioning openings, such as 9 and 10, are located at the ends of the arms. The two positioning openings on the same arm can be at different distances d1 and d2 from the center of the cross, but this is not mandatory. The two positioning apertures on one arm (e.g., 9 and 10 on arm 7) and the center of the cross are not collinear. The two positioning openings on one arm (e.g. 9 and 10 on arm 7) are preferably located at positions on either side of a line running through the center of the openings 3 and 6. Openings 3 and 6 will ultimately be in the area of the joint between two tiles, while openings 9 and 10 will be opposite tiles. The position of the positioning openings on the arms of the postionator, e.g. the cross, is advantageously the same on each arm of the cross. Positioning pins on the tiles of the tiled display can engage in the positioning openings of the cross. For cylindrical positioning openings and cylindrical positioning pins, the diameter of the positioning pins is usually slightly smaller, e.g. one hundredth mm smaller, than the diameter of the positioning openings. For each tile, two positioning pins will preferably engage in two positioning openings of at least one positioning device, e.g. cross, (more generally a tile may contain twice as many positioning pins than there are positioning devices, such as crosses, to be used with that tile ie, each tile has at least two positioning pins per positioning device, e.g., cross. More generally, there may be more than two positioning pins to connect a tile to a particular positioning device, e.g., cross. Referring to Figures 4 to 9, if the positioning pins of two tiles, e.g., T1 and T2, engage in the positioning apertures of the same positioning device, e.g., cross C1, which is attached to a support structure 12 (ie, the support structure controls the transversal movements of the tiles and the cross limited), the relative position of tiles T1 and T2 is fixed. In particular, for each tile T1 and T2 that is connected to the cross C1 by two positioning pins, the relative angular position of the tiles relative to each other and the positioning device, e.g. cross, is fixed (fixed). By fixed (fixed) it is meant that displacements of T2 (linear and angular) relative to T1 are limited by the mechanical properties of the positioning device, e.g. cross (ie the material of the cross, the geometry of the cross, such as the length of the arms, their width and thickness ...) and the play of the positioning pins in the positioning openings. This will for example be the case for a cross in PPS plastic with the dimensions, for example there are four arms which are at an angle of 90 ° to each other, as shown in Figs. 1, with an arm length of 60 mm, an arm width of 19-20 mm, and arm thickness of 4 to 5 mm. For example, if the geometry of the positioning device, e.g. cross, as indicated above and the tiles are rectangular, the tiles T1 and T2 will be essentially parallel to each other (in other words the sides of T1 are parallel to the corresponding sides of T2) and the distance between tiles T1 and T2 will essentially be determined by the dimensions of the positioning device, e.g. the cross Cl. The material and geometry of the cross are selected such that the deformation of the cross and the play of the positioning pins in the positioning openings will be negligible compared to the displacement allowed by the rubber fastening elements (e.g. the relative displacement of the tile T1 to with respect to the tile T2 caused by elastic deformation of the positioning device, e.g. the cross, and the play of the positioning pins in the positioning openings, less than 10% of the displacement is allowed by the rubber fastening elements and preferably less than 1% of the displacement allowed by the rubber fasteners). The positioning device, such as cross C1, thus simplifies the positioning and alignment of two adjacent tiles T1 and T2 during assembly of the tiled display. In accordance with each of the embodiments of the present invention, the positioning device and the first and second mounting means thus provide a positioning, alignment, and mounting arrangement for display and alignable display hoists. Assuming that the supporting structure that will support the tiles of the tiled display has already been constructed and that positioning devices, such as the crosses, have already been attached to the supporting structure, the assembly of the tiled display begins with the positioning of a first tile T1. The positioning pins of the tile T1 engage in the positioning holes of at least one positioning device, such as cross C1, allowing a first positioning of the tile T1 close to the desired end position for the tile T1. The fasteners used to attach a tile to the support structure are prepared, e.g. screws, washers and bolts are positioned, but still allow movement of the tile T1, thanks to the clearance between the screws and the opening through which they are positioned to become. The tile T1 can be moved within the plane of the tiled display to compensate for the tolerances of the structure and the tile itself. The amplitude of the movements of the tile T1 is limited by the rubber fixing elements of the positioning device, such as cross C1. An operator can therefore move the tile T1 without the risk of removing it too far from the original position (which is expected to be close to the ideal position for tile T1). Since there are two rubber fixing elements, rotation of the tile T1 is also limited, which further facilitates the alignment of the tile T1 with the support structure or with the local vertical direction. Once the position of the tile T1 is set, the permanent fastening means are tightened to hold the tile T1 in that position. Permanent fixing can be achieved by tightening the screws, washers and bolts mentioned above. The assembly of the tiled display is continued by placing a second tile T2 next to the first tile T1. Two of the positioning pins of the tile T2 engage in the corresponding positioning openings of the positioning device, such as cross C1. This determines the relative position of the tile T2 (e.g. the corresponding sides of the tiles T1 and T2 are parallel and the distance between the tiles T1 and T2 is determined) relative to the tile T1 and the positioning device, such as cross C1. The permanent fasteners for tile T2 are tightened, eg the screws, washers and bolts. The assembly of the tiled display is continued by allowing two of the positioning pins of a tile T3 to engage in corresponding positioning openings of the positioning device, such as cross C1. This determines the relative position of the tile T3 relative to the positioning device, such as cross C1 and tiles T1 and T2. The assembly of the tiled display is continued by allowing two of the positioning pins of a tile T4 to engage in corresponding positioning openings of the cross C1. This determines the relative position of the tile T4 relative to the cross C1 and the tiles T1, T2 and T3. If the tiled display contains more than four tiles, the tiles can be arranged in groups of four tiles or fewer. For example, for a tiled display of 5 by 2 tiles, as shown in Figure 4, a first positioning device, such as cross C1, can be used for a first group of 4 tiles (T1, T2, T3, T4), a second positioning device, such as cross C2, for a second group of four tiles (T5, T6, T7, T8) and a third positioning device, such as cross C3, for a third group of two tiles (T9, T10). In that case, the first tile of the second group will have to be aligned with the first group of four tiles without help from the positioning device, such as the cross, and the positioning device, such as the second cross, will be used to match the tiles of the second group with align each other. In a specific embodiment, the positioning device, such as cross C3, can be reduced to a T-shaped element T3. Such a T-shaped positioning and adjusting means is a specific embodiment of the positioning device, such as a cross, to align two elements (e.g. at the edges of a group of tiles). Alternatively, the positioning pins of the first tile T1 can be engaged in the positioning openings of more than one positioning device, such as the cross, as shown in Figure 5, where the positioning pins of T1 engage in positioning openings of four positioning devices, such as the crosses (C1 , C2, C3 and C4) The tolerance (deviation) that would exist between the distance of positioning pins on the tile and the positioning openings on different positioning devices, such as the crosses, is compensated by the displacement of the positioning device, such as the crosses, which allow the rubber fixing elements. Figures 5 to 9 show an example of a tiled display of 3 by 4 tiles (i.e. 3 rows of 4 tiles). A first tile T1 is located on the support structure, wherein the positioning pins of T1 engage in the positioning openings of the positioning device, such as the crosses C1, C2, C3 and C4 (see Figure 5). The position of the tile T1 can be adjusted before the permanent fastening means are tightened, e.g. the screws, washers and bolts as mentioned above. The assembly of the tiled display is continued by placing a second tile T2 next to the first tile T1. Two of the positioning pins of the tile T2 engage in the corresponding positioning openings of the positioning device, such as the cross C2. In the example of Figure 6, three other groups of two positioning pins of T2 will engage in the positioning openings of the positioning device, such as the crosses C3, C5 and C6. The tile T1 attached to the support structure with fasteners that are less accommodating than the rubber fastening element of the positioning devices, such as the crosses, the crosses C5 and C6 that will move, will, in a first approximation, be the only one moving (e.g. if the distance between the positioning openings in positioning devices, such as the crosses C2 and C5, is smaller than the distance between the corresponding positioning pins on T2, the positioning devices, such as the crosses C5 and C6, will move in the direction of the tile T1). Once at least two positioning pins of the tile T2 engage in the two corresponding openings of the positioning device, such as the cross C2 (as in Figure 6), the movements of the tile T2 in the plane of the tiled display will be limited. Since the tiles T1 and T2 are coupled by the positioning device, such as the cross C2, they will behave as a solid body in a first approximation in movements in the plane of the tiled display. This means that if the tile T1 is moved in the plane of the tiled display, the tile T2 and at least the positioning device, such as the cross C2, will move together with the tile T1, as if T1, T2 were a solid body. This means that, in a first approximation, the position and orientation of the tile T2 relative to the tile T1 is fixed (fixed). Assembling the tiled display is continued, as can be seen in Figure 7, by placing a third tile T3 next to the first and second tiles T1 and T2. As was previously the case with the tile T2, once at least two positioning pins of the tile T3 engage in the two corresponding openings of the positioning devices, such as the crosses C3 and C4, the tiles T1, T2, T3 and the cross C3 will a first approach as a solid body worn with movements in the plane of the tiled display. This means that, in a first approximation, the position and orientation of the tiles relative to each other will remain unchanged if they are subjected to movements in the tile of the tiled display (whereby said movements are limited in their amplitude by the rubber fixing elements) . As can be seen in Figure 8, a fourth tile T4 is applied and tiles are added until a tiled display of 3X4 tiles is aligned and attached to the support structure, as can be seen in Figure 9. In an alternative embodiment, the positioning device, such as the cross, is used without being attached to the support structure. In that case, the one or more positioning devices, such as the crosses, with which the tile T1 will be used, are connected to the tile T1 before T1 is applied to the tiled display. In the example of cylindrical positioning openings and cylindrical positioning pins as described above, if the difference in diameter is kept small enough, this ensures that the crosses and the tile remain connected together during handling of the tile T1. A difference in diameter of one hundredth mm is a good compromise between (a) ease of engaging the positioning pin in its positioning opening and (b) sufficient resistance to the release of the positioning pin from the positioning opening. Once the tile T1 is in position, T1 is confirmed. Additional positioning devices, such as the crosses, are added at the same time that additional tiles are placed and aligned with the tiles already attached to the support structure. The shape of the positioning devices mentioned above in each of the embodiments is not limited to that of a cross. Other shapes are possible depending on the geometry of the support structure and the cross-section of the tiles. The support structure can be made of a plate or be in the form of struts connected to each other by welding, riveting, nuts and bolts or other fasteners, so that the structure is flat and has less weight, but at the same time is strong and rigid. To achieve accurate positioning of the holes in the support structure, the structure can be placed on an X-Y table of an NC-controlled machine and the holes drilled accurately. Although the invention has been described above with respect to specific embodiments, this has been done for illustrative purposes only and not as a limitation of the invention, the scope of which will be determined in accordance with the appended claims.
