Abstract

The present invention relates to a support substructure for securing display pieces to a support structure of a tiled display, the support substructure being characterized in that it is connected to the support structure by means of a first mechanism that allows the display pieces to move independently of the presence or absence of adjacent display pieces in a plane parallel to the nominal plane (XY) of the tiled display.

Description

[0001] This application is a divisional application of application No. 201810947213.3, filed on August 20, 2018, entitled "Adjustable support structure for display panel". Technical Field

[0002] The present invention relates to an adjustable support for display panels and an array of display panels having the adjustable support. Background Technology

[0003] The alignment of small tiles in tiled displays is a well-known problem in this field. Tiled tile alignment is crucial to avoid introducing visual artifacts in images displayed on a tiled display. Throughout the tiled display, not only must the tiles be parallel, but the spaces and seams between them must also be of equal width.

[0004] Due to dimensional tolerances, such as those of the outline of the support structure or beams assembled to form small pieces for a tiled display, the width of the joints can vary depending on their position on the tiled display.

[0005] Small pieces can be fastened to the supporting structure, for example, by bolts and nuts. The positional tolerances of the holes through which the bolts must pass can also cause variations in the joint.

[0006] The beams supporting the structure may not be perfectly aligned, which will affect the alignment of the smaller blocks. This will also cause variations in the width of the joints along one side of the same smaller block.

[0007] Although there are several solutions for aligning the individual pieces of a tiled display, they either require complex mechanical connections between the pieces, as in US 8,384,616B2, or are time-consuming to install and adjust.

[0008] To avoid visual artifacts, adjusting the seams between the individual display panels in a tiled display is important. Seam adjustment relates to the alignment of the display panels. Techniques and apparatus for aligning the individual display panels in a tiled display are known in the art. For example, US 8,384,616 B2 describes how to align adjacent display panels with high precision using clips and sockets.

[0009] These and similar small-block alignment techniques assume that the LEDs themselves are properly aligned with the small blocks themselves.

[0010] LEDs are soldered to an LED board, which is then secured to a support plate. Alignment between the LED board and the support plate is typically achieved using one or more reference pins. These reference pins serve as one or more references to the support plate (e.g., its corners) to align the LED board. Unfortunately, there are positional tolerances for each LED relative to the LED board to which they are soldered; therefore, perfect alignment of the LED board to the support plate using reference pins on the LED board does not guarantee perfect alignment of the LEDs themselves with the support plate. Consequently, even if adjacent LED blocks are perfectly aligned, the relative positions of LEDs on different LED blocks may vary on a tiled display, introducing visual artifacts.

[0011] Another problem that the clips and sockets used in the prior art do not solve is the position or "z-coordinate" of the LED along the plane perpendicular to the LED panel. When the observer's gaze direction is not perpendicular to the plane of the tiled display, the change in the z-position of the LED from small to large pieces is the source of visual artifacts.

[0012] What is needed is a solution to adjust the distance between the top of the LED on the LED board and a reference object (such as the back surface of the support plate).

[0013] It is known in the art that the distance between two objects, for example, fastened together by screws and bolts, is adjusted by adding a washer between them. The problem with this technique is that if off-the-shelf washers are used, the distance between the two objects can only be changed by multiples of the washer thickness, or the washers must be machined for each LED board relative to the actual distance between the LEDs. This is neither practical nor economical.

[0014] A similar issue exists with tiled LCD panels. As the size of the seams between panels decreases, it becomes increasingly important to make adjacent panels as coplanar as possible.

[0015] While adjacent small sections must be aligned with high precision, the panel must also be easy to maintain. Therefore, it is important to have a fastening and alignment mechanism that is compatible with the mechanism used to connect power, control, and data signals from electronic devices to the LCD panel.

[0016] Four main approaches can be found in existing technologies that address the maintenance of tiled displays.

[0017] The first method is to enter through the front of the display surface (see...). Figure 1A ).

[0018] This is a relatively new approach, where the entire sign face is hinged open to expose the components. This design initially attracted many customers and manufacturers seeking innovative solutions for maintenance and repair. The main problem was the size limitation of the panel door. Beyond a certain size, the weight of the panel became dangerous for technicians maintaining the display, especially if the display was installed along the building facade and several meters or even tens of meters above the ground.

[0019] The second method is to enter through the front door (see...). Figure 1B This method is similar to the access method, but uses smaller doors on multiple sections of the sign. For safety reasons, it is preferable to limit the weight of each section to a few kilograms. Furthermore, the movement of the hinges and doors requires a minimum dimension for the seams surrounding the doors.

[0020] The third method is a rear entrance door. This method cannot be used for LED displays installed on the building facade.

[0021] The fourth method is to enter the LED panel from the front.

[0022] Individual LED modules or panels can be removed from the tiled display to access the components.

[0023] An example of front entry into an LED panel can be found, for instance, in US 7,055,271 B2, “Electronic display module having a four-point latching system for incorporation into an electronic sign and process”.

[0024] When a small panel must be removed for inspection, maintenance, and / or replacement, the solution proposed in US 7,055,271 uses a tool to trigger a release mechanism. When triggered, the release mechanism allows the panel to be moved off the plane of the tiled display by rotation or translation. This allows direct access to the structure behind the display panel, specifically the fastening device by which the panel is secured to the support structure of the tiled display. The display panel can slide along it or be hinged to it to rotate away from the support structure. Figure 1B The tiled display shown has two or four bars; the release mechanism increases the weight of the display and is not compatible with small display pieces that must be bent. Summary of the Invention

[0025] The objective of this invention is to provide an improved apparatus and method for accessing (approaching) display panels of a tiled display.

[0026] In a first aspect, embodiments of the invention relate to individual display blocks 500 of a tiled display fastened to a support structure by means of at least one second support substructure 33, wherein the display blocks can be fixed to the at least one second support substructure 44, which is characterized in that it is connected to the support structure by means of a first mechanism that allows the display blocks to move in a plane XY parallel to the nominal plane of the tiled display, independent of the presence or absence of adjacent display blocks.

[0027] Embodiments of the present invention include support substructures for securing display pieces 500 to a support structure of a tiled display, adjacent display pieces in the tiled display being separated by a nominal seam. A second support substructure 33 is characterized in that it is connected to the support structure by means of a first mechanism and a second mechanism, the first mechanism allowing each display piece to move in a plane parallel to the nominal plane XY of the tiled display to form a gap G between adjacent display pieces obtained by moving one or more display pieces from a first position P1 to a second position P2, the second mechanism fixing the position of the second support substructure 33 in the second position, wherein the gap G is larger than the nominal seam.

[0028] Therefore, the movement of the second support substructure 33 relative to the support structure means the formation of a space or gap G between adjacent small blocks. This gap G is larger than the nominal seam. By increasing the space or gap G between adjacent small blocks, it is easier to access the mechanism positioned behind the display surface, and this mechanism, upon activation, will release the display block 500 and allow it to be replaced by another display block and / or removed for maintenance and / or storage. This gap G is obtained by moving one or more display blocks from a first position P1 to a second position P2.

[0029] The supporting structure can be a component or a truss network. The supporting structure can be a wall; the wall can be fitted with trusses, and the supporting substructures can be fastened to the trusses.

[0030] The first mechanism may be driven by, for example, a motor. Alternatively, the first mechanism may be driven by a key or crank operated by a human operator.

[0031] The first mechanism may include means for converting the rotational motion of a motor or manually operated crank into translation of the second support substructure 33.

[0032] Specifically, the first mechanism includes a sector gear (segment gear) 312 and a pin 331. During rotation, the sector gear applies a force to the second support substructure 33 via the pin 331.

[0033] The first mechanism may include one or more guiding devices that will limit the direction and amplitude of movement of the second support substructure 33.

[0034] The first mechanism may include a release mechanism. When released, the first structure cannot independently (self-maintain) the position of the second support substructure 33 when a force is applied to the second support substructure 33 and / or the display block 500 it supports.

[0035] In another aspect of the invention, each display block has one or more contact elements 510, 520, 530, and 540, by means of which the display block can mechanically interact with adjacent display blocks, particularly with display blocks positioned above it. This is particularly advantageous when no electric motor is used to power the first mechanism. Specifically, the contact elements can transmit force from the bottommost display block in a column to all other display blocks in the same column.

[0036] In another aspect of the invention, a second mechanism may fix the position of the second support substructure 33. This second mechanism can fix the position of the second support substructure 33 by pushing a pin 332 fastened to it. Specifically, the second mechanism may include a lever or hammer 316, which may be in two positions: in a first position H1, the hammer does not prevent free movement of the pin 332; and in a second position H2, the hammer prevents free movement of the pin 332. This is advantageous if the display block must be held in its second position without power consumption (e.g., if a motor is used) or without the need for continuous human intervention (e.g., maintaining applied force on the mechanism).

[0037] In another aspect of the invention, each display piece of the tiled display is secured to or matched to an intermediate third support substructure, which is characterized in that it includes a mechanism for moving the display piece outside the display plane XY.

[0038] Another objective of the present invention is to provide an improved apparatus and method for aligning display pieces in a tiled display. Such an alignment mechanism 32 can be used in conjunction with a second support substructure 33, each support substructure for securing display pieces 500 to a support structure of the tiled display, adjacent display pieces in the tiled display being separated by a nominal seam. The second support substructure 33 is characterized in that it is connected to the support structure by means of a first mechanism and a second mechanism, the first mechanism allowing each display piece to move in a plane parallel to the nominal plane XY of the tiled display to achieve a gap G between adjacent display pieces obtained by moving one or more display pieces from a first position P1 to a second position P2, the second mechanism fixing the position of the second support substructure 33 in the second position, where the gap G is larger than the nominal seam. The alignment mechanism includes an element having a central section having arms secured to the central section, each arm extending radially from the central section.

[0039] For example, each wall can be positioned symmetrically around the central section, and optionally, two successive arms can be spaced 90° apart.

[0040] The holes in each arm are adapted to receive pins or screws to be fastened to the second support substructure.

[0041] The first element 258, together with the alignment mechanism 32, can be screwed onto the first fastening bolt 250.

[0042] The device for moving the alignment mechanism in a direction parallel to the axis of the first fastening bolt 250 can be achieved by means of rotation of the first fastening bolt 250.

[0043] The alignment mechanism 32 preferably rotates freely around the first element 258 until the nut 253 is tightened.

[0044] The first fastening bolt 250 and the first element 258 can pass through the spring-loaded section G252, which allows movement of the first element 258 within the limits of the opening G251 along the orthogonal direction of the alignment mechanism 32. In the absence of any other greater force, the spring-loaded section G252 allows the alignment mechanism 32 to self-align around the first fastening bolt 250.

[0045] As long as the nut 253 is not tightened, the alignment mechanism 32 can tilt relative to the first fastening bolt.

[0046] Before being secured relative to the first fastening bolt, the alignment mechanism 32 will have all six degrees of freedom to move relative to the first fastening bolt 250.

[0047] The alignment mechanism 32 can be fastened relative to the first element 258 by tightening the nut 253, thereby clamping the discs 254, 255 in the central section G256 and between the first element 258 and the nut 253 through the opening G251.

[0048] The first element 258 can be fastened to the bolt by means of a countersunk nut placed on the bolt 250 and directly below the first element 258.

[0049] The translational and angular displacements of the first fastening bolt 250 within the hole G251 allowed by the spring-loaded section G252 are permitted: despite the positional tolerances of the bolt holes for fastening the small blocks, the adjacent small blocks installed do not have an increase in the seam around the panel.

[0050] The first support substructure 31 can be fastened to the alignment mechanism 32 by means of a single bolt 257 fastened to one of the geometries G211, G221, G231, G241.

[0051] The first support substructure 31 has a mating section G120 corresponding to the arm 220 of the alignment mechanism 32.

[0052] The walls G121 and G122 of the mating sections on both sides of the arm 220 are adapted to prevent the arm 220 from rotating about the axis of the single bolt 257.

[0053] The pin-shaped geometry on each arm (G222 on 220) can be fitted into holes in the extensions 130 and 140 of the first support structure 31, thereby positioning the support structure 10 relative to the alignment mechanism 32 and relative to any adjacent support structure.

[0054] The holes for the single bolt 257 are located in each arm 210, 220, 230, 240, within the pin-shaped geometry (G221 is within pin G222 in arm 220).

[0055] The bolt-shaped geometry is fixed to the alignment mechanism 32 above the pin, and the single bolt 257 is replaced with a nut.

[0056] In the case of a tiled display wall comprising n*m display blocks 500 and (n+1)*(m+1) alignment mechanisms 32, at least two of the four holes G211, G221, G231, G241 of each alignment mechanism 32 at the outer periphery of the tiled display wall are not used to keep the support structure 10 fixed.

[0057] When adding other support structures 10 to the tiled display wall, use at least two of the four holes.

[0058] A tiled display can be connected to the aforementioned support structure. Attached Figure Description

For example, in Figure 2 and Figure 4 In the example, the nominal display plane is the XY plane. The nominal display surface is composed of small blocks T1 to T9 (in... Figure 4 The surface is formed by the sum of the display surfaces (which are represented by 9 small rectangular blocks).

[0082] Example Description of Implementation Examples

[0083] Figure 3 An exploded view of the various support substructures according to the invention, along the landscape orientation, and a display panel 500 are shown. This display panel can be aligned with other panels of the tiled display and is easily accessible for maintenance and repair.

[0084] The first support substructure 31 can be fastened to, for example, a wall via alignment mechanisms 32A, 32B, 32C, and 32D. Figure 3 (Not shown in the diagram) and / or a truss network. The trusses themselves may be fixed to the wall, or they may form a self-supporting structure. The alignment mechanism includes cross-shaped components 32A, 32B, 32C, and 32D. The alignment mechanism allows adjacent display blocks to be aligned relative to each other in the X, Y, and Z directions.

[0085] The second support substructure 33 is supported by the first support substructure 31. The second support substructure is movable relative to the first support substructure 31.

[0086] The movement of the second support substructure 33 relative to the first support substructure is limited in magnitude and direction, as will be described later. Specifically, the movement of the second support substructure is accomplished along a direction parallel to the XY plane of the display. The movement of the second support substructure 33 relative to the first support substructure 31 is intended to create a space or gap G between adjacent segments, which is larger than the nominal seam. By increasing the space or gap G between adjacent segments, it is easier to access the mechanism positioned behind the display surface, and this mechanism, upon activation, will release the display segment 500 and allow it to be replaced by another display segment and / or removed for maintenance and / or storage.

[0087] The movement of the second support substructure can be controlled by a (rotary or linear) electric motor. This motor can be controlled by control signals sent to, for example, electronics typically associated with the display panel. Alternatively, the movement can be controlled by a manual crank, as will be described in detail below.

[0088] To further facilitate access to the fastening device that secures the display panel to the support structure, a third support substructure 34 may be used. The third support substructure 34 is supported by the second support substructure 33. The third support substructure is movable relative to the second support substructure 33.

[0089] The motion of the third support substructure has XY components perpendicular to the display plane. The motion of the third support substructure relative to the second support substructure can be translation, rotation, or a combination of both.

[0090] A series of mechanisms can be used to trigger and / or control the movement of the second and third substructures. These mechanisms are particularly relevant when motors are not used to change the position of the display blocks.

[0091] In the first example of the embodiment, it is assumed that the Y-axis is parallel to the direction of the local gravitational field: g = -g.1y.

[0092] The first mechanism can move the small block from the first position P1 (nominal position) to the second position P2 (which, for example, is the position it has during maintenance).

[0093] The second mechanism can prevent the small block from returning to its first position P1. This is advantageous, for example, when entering the mechanism for releasing the display block requires a gap between the display block and all adjacent display blocks.

[0094] The third mechanism is used to control the movement of the small block and to position it in the third or maintenance position.

[0095] These mechanisms and how they operate will be described in the case of a tiled display consisting of nine display blocks T1, T2, T3, ..., T9 assembled in three columns of three adjacent display blocks.

[0096] Figure 4 This illustrates the relative positions of nine display panels (examples of 3-row and 3-column display panels) in normal use. As shown, the nominal positions of the display panels or panels T1 to T9 are in the same XY plane. The distance between two display panels is the nominal seam separating the panels of the tiled display. This nominal seam can be selected, for example, between 0 mm and 2 mm or more.

[0097] In order to access the support and alignment mechanism that allows the display pieces to be fastened to / released from the tiled display, the first mechanism is activated and triggers the positioning of display pieces T7, T8, and T9 as follows: Figure 5 The first motion is shown. Figure 8 The position shown can be achieved by translating away from the nominal position along the direction DIR (which is, for example, at a 45° angle relative to the main direction of the display).

[0098] The first movement can be common to all small blocks in the same column. Figure 4 and Figure 5In the example, blocks T7, T8, and T9 move together. This can be achieved, for example, by simultaneously driving several blocks in a column, or by applying force to the bottom block of the column, and the bottom block transmitting that force to the other blocks in the column (e.g., by pushing on contact elements 510, 520, 530, 540), shown in the figure (contact element 540 is obscured by display block 500). Elements 510, 520, 530, and 540 are mounted on display block 500 to contact the surfaces of adjacent contact elements of adjacent display blocks. They protrude slightly from the perimeter of the display itself. The size of this protrusion defines the width of the seam between adjacent blocks and is preferably less than one millimeter. Specifically, the size of this protrusion is the same for all contact surfaces (i.e., the sides of a contact element that contact the corresponding sides of adjacent contact elements). In a special case, when the contact surfaces do not protrude but are flush with the perimeter (or outer boundary) of the display itself, there is no seam between adjacent blocks.

[0099] Figure 6A Figures 6B and 6C illustrate the method for transferring small piece T9 from its... Figure 4 The position shown in the diagram is moved to its... Figure 5 The location of the mechanism is shown in the image.

[0100] Figure 6A The diagram shows different support substructures, as well as the first and second mechanisms. This view is taken from the rear of the first support substructure.

[0101] like Figure 6A As shown, the first mechanism includes a gear 311. This gear 311 is rotatable about a rotation axis Ax1 that is fixed relative to the first support substructure 31. This rotation axis Ax1 is preferably perpendicular to the XY plane (the plane of the display surface). The gear 311 is mechanically connected to a sector gear 312. The sector gear 312 has a rotation axis Ax2 that is fixed relative to the first support substructure 31. When the gear rotates, it causes the sector gear 312 to rotate.

[0102] As shown in Figures 6B and 6C, the sector gear 312 can interact with the second support substructure 33 via, for example, a pin 331 fastened to the second support substructure 33. The position of the pin 331 relative to the second support substructure is constrained, for example, by a groove 313 located in the second support substructure 33 (illustrated in Figures 6B and 6C). This groove 313 generates movement along the direction DIR and limits the maximum range of movement of the second support substructure. Alternatively, as... Figure 6AAs illustrated, the movement of the second support substructure relative to the first support substructure can be constrained by guide rails and ball bearings. Ball bearings 3150 and 3151 are fastened to the first support substructure 31 and engage in the guide or opening 3152 or 3153. Other guiding mechanisms are possible.

[0103] Pin 331 engages in recess 3121 of sector gear 312. When sector gear 312 rotates (e.g., from its...), Figure 6A (Or from the initial position shown in Figure 6B to the position shown in Figure 6C), it is pushed against pin 331. Pin 331 is fastened to the second support substructure 33, and any displacement of pin 331 is accompanied by displacement of the entire second support substructure 33. Δ This displacement Δ Completed parallel to the direction Dir.

[0104] Gear 311 contacts locking element 315, which is fixed in position relative to the first support substructure 31 to prevent element 33 from falling back along direction DIR. When pushed, pin 314 (part of locking mechanism 315) releases the sector gear. The sector gear then freely returns to its original position. Figure 6A And the unused position shown in Figure 6B.

[0105] The gear can be driven, for example, by a manual crank, key, or motor (such as an electric motor). When the gear is driven by a manual crank, the locking element 315 and the release pin 314 are particularly useful. With a sufficiently high gear ratio, the electric motor can easily generate enough torque to hold the display block in the second position P2 without excessive power dissipation and without the assistance of the locking element.

[0106] The advantage of using an electric motor to change the position of the display unit is that it limits the number of mechanisms required to access the display unit. Specifically, when one electric motor is used for each display unit, the second and third mechanisms described further below may not necessarily be necessary, although they can still be advantageously used, for example, to enable the use of a smaller motor and / or reduce power dissipation.

[0107] When the second support substructure of small block T9 moves upward, it pushes against the second support substructure of small block T8, causing it to move upward again. When it moves upward, the second support substructure of small block T8 pushes against the second support substructure of small block T7, causing it to move upward along direction DIR. As previously mentioned, the force pushing the small blocks upward can be achieved through contact elements (in... Figure 3 In the example, 510, 520, 530, and 540 are passed from the lower block to the higher block.

[0108] The first mechanism can be used to generate, such as Figure 5The first gap between the two rows of small blocks is shown. In some embodiments of the invention, the first gap may be sufficient to allow access to a release mechanism that provides access to a fastening device for securing the display blocks to the support structure of the tiled display. The space D between the two rows of small blocks T4, T5, T6 and T7, T8, T9 is larger than the nominal seam. D can be as large as, for example, 10 or 15 cm, and provides access, for example, to a lever or switch that, when activated, triggers a mechanism that pushes the display blocks out of the nominal display plane. For example, a linear motor can push the blocks out of the nominal display plane in a direction perpendicular to the nominal display plane.

[0109] It may be advantageous to be able to access small sections of the display that need to be entered for maintenance (e.g., Figure 8 (As shown in the case of small block T9) a gap G is created around its perimeter. This is advantageous if, for example, the release mechanism needs to move outside the nominal display plane, and this movement needs to be along the gap on the horizontal side of the display block, or if a motor cannot be used to push the block outside the display plane, etc. In other words, the gap around the display block provides more freedom to use different release mechanisms, different connection devices to connect the display block to power and control signals, etc.

[0110] To illustrate how the release mechanism of display block 500 is accessed in these situations, consider the example of block T9.

[0111] T9 can be separated from small block T8 by causing it to fall back along the direction towards its initial position or first position P1. The desired position of T9 can be, for example, as follows: Figure 8 As shown. This position is the third fixed position P3, which is the position that the small piece can have within the display plane of the tiled display. Alternatively, T9 can be moved (or moved) to its initial position P1.

[0112] In order to keep small pieces T8 and / or T7 in Figure 5 The positions shown are (T8 and T7 in) Figure 5 In their second position P2), if T9 experiences a process toward it Figure 4 The second movement, returning from the initial position shown, requires a second mechanism. In practice, if the force used to push the small block upwards is transmitted via, for example, contact elements 510, 520, 530, and 540, if small block T9 moves downwards, small blocks T8 and T7 will follow, unless another force holds them in place. The purpose of this second mechanism is to create gaps between adjacent display small blocks in the same column (i.e., between a display small block and the adjacent display small block above it).

[0113] An example of such a structure is in Figure 6A As shown in Figures 7A to 7B.

[0114] The mechanism includes a hammer 316 that is rotatable about its axis Ax3. This axis Ax3 may be, for example, perpendicular to the display plane XY and has a fixed position relative to the first support structure 31.

[0115] In the first position H1 (in Figure 6A As shown in Figure 7A, the hammering member 316 allows the second support substructure 33 to move along the direction DIR. Specifically, the head of the hammering member 316A does not obstruct the pin 332 fastened to the second substructure.

[0116] In the second position H2 (shown in Figure 7B), the head 316A of the hammer 316 approaches the second support substructure 33 as it moves back to its initial position (the support substructure 33 and...). Figure 4 The position of the small display block shown corresponds to the position where pin 332 can occupy along the direction Dir. If the sector gear is released, gravity will freely bring the second support substructure back to its lowest position, but the head 316A of the hammer 316 applies force to the second support substructure 33 through pin 332, thereby keeping the second support substructure 33 in the raised position.

[0117] The position of the hammer can be changed, for example, by applying force to the rod or arm 316B. The hammer 316, its head 316A, and the rod 316B can be cast as a single solid mechanical element.

[0118] Force can be generated Figure 6A The notch 317 in the translated or sliding rod or plate 318 is applied to the rod portion 316B. For example... Figure 6A As shown, the translational plate 318 and notch 317 of the small block, such as T9, apply force to the rod of the hammer 8316 associated with the small block, such as T8, directly above.

[0119] In some cases, it may be advantageous to avoid small pieces like T9 returning completely to their original position P1, and instead fix the small piece in an intermediate position between the first position P1 and the second position P2, or in a third position P3. Figure 8 Here is an example where small block T9 is maintained in a third position P3, between P1 and P2. Figure 11An example is shown where block T5 is held in the third position P3, while blocks T4, T7, T8, and T9 have been moved (by means of the first mechanism) to their second positions, and 76 has returned to its first position. This creates a gap around display block T5. This provides additional freedom in designing a release mechanism that, when block T5 must be replaced, for example, will place the display block (in this case, T5) outside the plane of the display plane.

[0120] Keeping a small block like T9 in the third position P3 can be achieved, for example, by using a third mechanism to prevent the small block T9 from returning to its lowest position P1. To maintain the small block T9, it might be desirable to be able to enter it from all four sides, such as... Figure 8 As seen (depending on the mechanism used to remove the display piece from the display plane).

[0121] Figure 9A The example given is a third-party organization. Figure 9A This shows when a small block, such as T9, is in its nominal position (e.g., Figure 4 The structure of the mechanism shown in the figure.

[0122] Plate 901 is fastened to the second support substructure 33. Opening 903 in plate 901 defines a set of possible positions of plate 901 relative to the first support substructure 31. Alternatively, opening 903 may be implemented directly in the second substructure.

[0123] Pin 902 is fastened to plate 318. Plate 318 can be positioned relative to the first support substructure along a single direction, Dir 2. Figure 9A Movement from left to right or right to left. Figure 9A and Figure 3 In the example shown, the direction Dir 2 is parallel to the bottom and top of the small block, such as T9, which corresponds to the horizontal direction (perpendicular to the local gravitational field).

[0124] Plate 318 can slide in the first support substructure 31 or in the guide fastened to the first support substructure 31.

[0125] Opening 903 may include two parts 903A and 903B (composed of...) Figure 9A (Separated by dashed lines). If pin 902 occupies the first position relative to the first support substructure 31, the second support substructure can move further along the direction Dir (the magnitude of this movement can be like...). Figure 9A Points A and B in the diagram are equidistant.

[0126] Figure 9A This shows when a small block (e.g., block T8) is in its nominal position (i.e., in such a position as...). Figure 4 The relative positions of plate 901 and pin 902 during normal use are shown.

[0127] Figure 9B This shows that when a small block (e.g., small block T8) rises as previously described (i.e., as... Figure 5 (As shown) the relative positions of plate 901 and pin 902.

[0128] If pin 902 occupies the position on the second part 903B of opening 903, the maximum range of motion of the second support substructure can be limited to... Figure 9C The distance between point C and point D. When pin 902 is located at point D (e.g., Figure 9D When (as shown), plate 901 can no longer slide back, and the small piece (e.g., T9) remains as shown. Figure 8 The middle position shown.

[0129] Once pin 902 is in position C and the small piece, such as T9, falls back towards its original position P1, pin 902 will be pushed into the space 9021 between the two teeth of the cogwheel 905. The cogwheel 905 can rotate in one direction. Figure 9C and 9D As can be seen, the end of the hook 906 can only disengage from the space between the two teeth of the gear when the gear rotates in the first direction. When the gear rotates in the first direction, one of the (upstream) teeth of the gear will push the inclined surface of the hook and disengage the hook. In the opposite direction, the hook remains engaged in the space between two adjacent teeth, thereby preventing the wheel from actually rotating. Figure 9E This illustrates how the hook disengages from the gear 905 as plate 901 moves downward under the influence of gravity. As plate 901 falls, pin 902 enters the space between the two teeth of gear 905, and is pushed against one side of the gear.

[0130] The position of pin 902 relative to plate 901 can be determined by applying force to plate 318 from B ( Figure 9B Switch to C( Figure 9C (Board 318 in) Figure 9B and Figure 9C (Slide between right and left).

[0131] The movement of plate 318 (associated with the first small block, such as T9) can be coupled to the movement of a lever used to change the position of a hammer associated with the second small block (such as T8). If the force applied to small block T9 is released, T9 will position itself as follows: Figure 8 As shown, T8 will maintain its position (its movement is blocked by the hammer associated with the small piece T8). This coupling can... Figure 6A It can be seen in the upper right corner.

[0132] When the operator wants to manipulate, for example, small piece T9, the operator can access the plate or rod 318 in the space between small piece T9 and small piece T6. By applying force to the plate 318, the operator will move the pin 902 from the corresponding... Figure 9B Position B moves to Figure 9C Position C is shown. At the same time, the rod 318 changes the construction of the hammer 8316 associated with the small block T8.

[0133] By releasing the locking element 315 of the small block T9, the sector gear 312 is pushed back toward its original position under the weight of the small block T9 until the pin 902 reaches position D and presses against the upper boundary of the opening 903B.

[0134] Meanwhile, the structure of a tiled display is as follows: Figure 8 What we see there.

[0135] Now, a space of 1 / 2D exists between small pieces T8 and T9, which is larger than the original seam. The operator can use another rod to release the third support substructure 34. The third support substructure 34 is in Figure 3 , Figure 6A , Figures 10A to 10D and Figure 11 This can be seen from the text.

[0136] When all the small pieces are in the same position Figure 8 In the position shown, the components of the mechanism behind the display block T9 can enter through the gaps G on the vertical and horizontal sides of the block T9 (thus giving more freedom in designing the mechanism to release the display block). Figure 10A A cross-section of the mechanism for moving the small piece out of the display plane XY is shown. Element 341 can be, for example, a clamp that can be accessed through the gap between small pieces T8 and T9. More than one element 341 can be present along the X direction. When element 341 is activated, it releases the support substructure 34, and then... Figure 10B The device is shown rotating about axis Ax4. Ax4 is parallel to the display plane. In this example, the rotation axis Ax4 is parallel to, for example... Figure 3 The X-axis of the coordinate system shown. Display panel 500 (in...) Figure 10A or Figure 10B (Not shown) It can be hung on the third support substructure 34 along a rotation axis parallel to Ax4. When the support substructure 34 rotates out of the display plane, under the weight of the small piece 500, the display small piece 500 can, as Figure 10CIn the idle position shown, it remains parallel to the display plane. The display module can, for example, be hung on axis Ax7, which is fastened to the third support substructure 34. This axis Ax7 is parallel to axis Ax4. The range of rotation about axis Ax4 can be limited, for example, by arm 342. Arm 342 has a first end that can rotate about a first rotation axis Ax5, which is fixed to the second support substructure 33. Arm 342 has a second end that can rotate about a second rotation axis Ax6, which is fixed to the third support substructure 34. Figure 10A and Figure 10B In the example shown, rotation axes Ax5 and Ax6 are parallel to rotation axis Ax4. The length of arm 342 and the positions of axes Ax5 and Ax6 determine the range of rotation of the third support substructure 34 about axis Ax4. Other structures may also limit the range of rotation of the third support substructure about axis Ax4.

[0137] Figure 10C and Figure 10D The cross-section is shown in the position of the display substructure 500 relative to each support substructure, and specifically relative to the third support substructure 34, when the display substructure 500 is idle.

[0138] One or more hooks 505 fastened to the rear of the display unit 500 spread out along axis Ax7, allowing the display unit 500 to rotate about axis Ax7.

[0139] The display module 500 has one or more connectors on the rear side of the module (e.g., Figure 12 501 is used for data and control signals, while 502 is used for power supply.

[0140] Connectors for connecting electronic modules (such as power supply modules and processing devices) to control and power the display unit 500 are preferably mounted on the second support substructure 33. The PSU and processing device can be secured to either the first support substructure 31 or the second support substructure 33, provided that the electrical connection (such as a cable) between the PSU and processing device and the connectors on the second support substructure that will mate with the corresponding connectors 501 and 502 can accommodate the movement of the display unit from the first position P1 to the second position P2.

[0141] In another example of the invention, the individual display blocks of the tiled display are secured to a support structure by means of at least one support substructure 33. The display blocks can be fixed to this at least one support substructure, characterized in that it is connected to the support structure 33 by means of a first mechanism that allows movement of the display blocks in a plane parallel to the nominal plane of the tiled display. This at least one support substructure corresponds to the second substructure 33 of the foregoing embodiment. In this case, each second substructure is secured to a common support structure, eliminating the need for a first support substructure 31. As in the foregoing embodiment, a drive mechanism can be provided to drive more than one display block, for example, blocks positioned in a column (along a direction parallel to the local (in-situ) vertical). Alternatively, each block can have its own drive mechanism (e.g., a wirelessly activated motor). For example, for a tiled display comprising three columns, each with three display blocks, activating the drive mechanism of block T8 will cause blocks T8 and T7 to move away from the remaining display blocks along direction DIR. The difference from the previous embodiment is that the small block T9 can maintain its position. The movements applied to T8 and T7 can be different. For example, a motor associated with the first mechanism of the small block T7 can bring the small block T7 to its second position P2, while at the same time a motor associated with the first mechanism of the small block T8 will bring the small block T8 to its third position P3, thereby creating a gap around the small block T8.

[0142] The advantage of the first support substructure is that it can be used to correct gaps affecting the support structure (i.e., the wall and / or truss network), thereby improving not only the accuracy of the alignment of the display pieces along the X and Y directions, but also the accuracy of the alignment along the Z direction.

[0143] The means for aligning display panels or other structures such as frames along the Z-direction relates to a dependent or independent aspect of embodiments of the invention. Aligning up to four adjacent panels is achieved by means of... Figure 3 This is accomplished by at least one alignment mechanism 32 shown (32A, 32B, 32C are visible, while 32D is obscured). Figure 3 The alignment mechanism 32 shown can be used for reference. Figures 3 to 12 Each of the described embodiments serves as a subordinate alignment element. These combinations are expressly included in this invention and are expressly disclosed herein. (See reference...) Figures 13A to 15B The described alignment element 32 can be used as a reference. Figures 3 to 12 Any of the embodiments described herein, and these combinations thereof, are expressly included in and disclosed herein. Specifically, support substructure 33 may be secured to a support structure, such as a wall, by means of another support substructure 31, which is secured to the support structure by means of an alignment mechanism 32. The alignment mechanism 32 may be used to align adjacent display sub-blocks.

[0144] Figures 13A to 15B The alignment mechanism 32 shown also involves a separate device that can be used not only for reference Figures 3 to 12 The various frameworks and structures described.

[0145] Specifically, these embodiments of the present invention (such as...) Figures 13A to 15B and Figure 3 (As shown in detail) may relate to a support substructure for use in fastening a tiled display having an array of display blocks to a first support structure, the support substructure being fastened to the support structure by means of an alignment mechanism 32 for aligning adjacent display blocks, and also includes a first fastening bolt 250 perpendicular to the first support structure, and means for displacing the alignment mechanism 32 in a direction parallel to the axis of the first fastening bolt 250.

[0146] Figure 13A A top view of element 32 is shown, while Figure 13B A cross-sectional view is shown according to an embodiment of the present invention.

[0147] Component 32 includes a central segment G256. The central segment G256 may be, for example, cylindrical. Arms 210, 220, 230, and 240 are fastened to the central segment. Each arm and the central segment may, for example, be machined from the same piece of material (e.g., steel, aluminum, etc.). Figure 13A In a preferred example, the arms are positioned symmetrically around the central segment (preferably with a 90° angle between successive arms). The arms of the alignment mechanism can be fastened to different first support substructures. Figure 13A In the example, the holes in each arm can accommodate pins or screws to be fastened to the first support substructure (hole G211 in arm 210, hole G221 in arm 220).

[0148] The alignment mechanism 32 can be fastened to a tiled display support structure (e.g., a wall). Figure 13A and Figure 13B In the example, this can be achieved by first positioning bolt 250 preferably perpendicular to the tiled display support structure or wall. Figure 13A and Figure 13B (Not shown in the image) is tightened to complete the process.

[0149] Components 250 and 258 preferably have matching threads. Component 258 is screwed onto bolt 250 together with alignment mechanism 32. Therefore, rotation of component 258 about bolt 250 allows displacement of alignment mechanism in a direction parallel to the axis of bolt 250. Particularly preferred is a solution in which alignment mechanism 32 rotates freely about component 258 until nut 253 is tightened.

[0150] Bolt 250 and carrier 258 pass through, preferably, a spring-loaded section G252, which allows movement of the alignment mechanism 32 in the X and Y directions, around carrier 258, within the limits of opening G251. In the absence of other greater forces, the presence of the spring-loaded section G252 enables the alignment mechanism 32 to self-align around bolt 250. The alignment mechanism can tilt relative to the bolt (angle α is variable) as long as nut 253 is not tightened.

[0151] Therefore, before being fixed relative to the bolt, the alignment mechanism can move with all 6 degrees of freedom (3 translational degrees of freedom and 3 rotational degrees of freedom) relative to the bolt 250.

[0152] After the alignment mechanism 32 is pushed into the desired position, the carrier 258 is aided by a countersunk nut ( Figure 13B (Not shown) Fastened to the bolt, the countersunk nut is placed on the bolt 250, just below the carrier 258. Then, the alignment mechanism is fastened relative to the carrier 258 by tightening the nut 253, thereby clamping the discs 254 and 255 through the opening G251 in the intermediate section G256 and between the carrier 258 and the nut 253.

[0153] Figure 14A A top view of the alignment mechanism is shown with the alignment mechanism 32, the spring-loaded section G252 and the bolt 250 preferably centered. Figure 14B and Figure 14C This illustrates how the alignment mechanism 32 can move relative to the bolt 250 and the carrier 258.

[0154] Figure 14C The spring-loaded section G252 shows the possible displacement ΔY of the alignment mechanism along the Y direction.

[0155] Preferably, the translational and angular displacement of the bolt 250 within the hole G251, allowed by the spring-loaded section G252, enables the installation of adjacent small pieces without increasing the seam around the panel, despite tolerances in the position of the bolt holes used to fasten the small pieces to, for example, the wall.

[0156] like Figure 15A and Figure 15B As shown, fastening the first support substructure 31 to the alignment mechanism 32 can be accomplished by means of a single bolt 257 fastened in one of the geometries G211, G221, G231, G241, especially if the first support substructure 31 has a mating section 120 corresponding to, for example, an arm 220 of the alignment mechanism 32. The walls G121 and G122 of the mating section on both sides of the arm 220 will prevent the arm 220 from rotating about the axis of the bolt 257. The pin-shaped geometry on each arm (see, for example, [reference needed]). Figure 13B The G222 on each of the arms 220 is fitted into holes in the extensions 130 and 140 of the first support structure 31, thereby positioning the support structure 10 relative to the alignment mechanism 32 and relative to any adjacent support structures. Particularly preferred is this geometry, in which the holes for bolts 257 in each of the arms 210, 220, 230, 240 are positioned within this pin-shaped geometry (e.g., see...). Figure 13A (The hole G221 is inside the pin G222 in the arm 220). Alternatively, it is possible to replace the pin-shaped geometry (e.g., 222) on the alignment mechanism 32 with a bolt-shaped geometry fixed to the pin (like a fixing bolt), and to replace the bolt 257 with a nut.

[0157] Figure 15A and Figure 15B It also shows that: for example Figure 13A In the preferred design of the alignment mechanism shown, in the case of a tiled display wall comprising n*m display blocks 500 and preferably (n+1)*(m+1) alignment mechanisms 32, at least two of the four holes G211, G221, G231, G241 of each alignment mechanism 32 at the outer periphery of the tiled display wall are not used to hold the support structure 10 fixed. These holes can be used when adding other support structures 10 to the tiled display wall at a later stage.

[0158] Summarizing the above, a support substructure is disclosed, wherein the alignment mechanism 32 includes an element having a central section with arms fastened to the central section, each arm extending radially from the central section. They extend radially in a divergent manner. Each arm can be symmetrically positioned around the central section, and optionally, successive arms are spaced 90° apart. Holes in each arm can be used to receive pins or screws to be fastened to the first support substructure. The first element 258, together with the alignment mechanism 32, can be screwed onto a first fastening bolt 250. The means for displacing the alignment mechanism in a direction parallel to the axis of the first fastening bolt 250 is by means of rotation of the first fastening bolt 250. The alignment mechanism 32 can be freely rotated about the first element 258 until the nut 253 is tightened.

[0159] The first fastening bolt 250 and the first element 258 can be moved within the limits of the opening G251 along the orthogonal direction of the alignment mechanism 32 about the first element 258. In the absence of any other greater force, the spring-loaded section G252 allows the alignment mechanism 32 to self-align about the first fastening bolt 250. The alignment mechanism 32 can tilt relative to the first fastening bolt as long as the nut 253 is not tightened.

[0160] Before being secured relative to the first fastening bolt 250, the alignment mechanism 32 will have all six degrees of freedom to move relative to the first fastening bolt 250. The alignment mechanism 32 can be secured relative to the first element 258 by a tightened nut 253, thereby clamping discs 254, 255 in the central section G256 and between the first element 258 and the nut 253 through the opening G251. The first element 258 can be secured to the bolt by means of a countersunk nut placed on the bolt 250, just below the first element 258. The translational and angular displacements of the first fastening bolt 250 within the opening G251 allowed by the spring-loaded section G252 allow that, despite the positional tolerances of the bolt holes for fastening the small pieces, the installed adjacent small pieces do not have an increase in the seam around the panel.

[0161] The first support substructure 31 can be fastened to the alignment mechanism 32 by means of a single bolt 257 fastened in one of the geometries G211, G221, G231, G241. The first support substructure 31 has a mating section G120 corresponding to an arm 220 of the alignment mechanism 32. The walls G121 and G122 of the mating section on both sides of the arm 220 prevent the arm 220 from rotating about the axis of the single bolt 257. A pin-shaped geometry (G222 on 220) on each arm is fitted into a hole in the extensions 130 and 140 of the first support substructure 31, thereby positioning the support structure 10 relative to the alignment mechanism 32 and relative to any adjacent support structure. The holes for the single bolt 257 in each arm 210, 220, 230, 240 are positioned within the pin-shaped geometry, for example, G221 within the pin G222 in the arm 220. A bolt-like geometry can be fixed to the alignment mechanism 32, above the pin, and a nut can be used instead of the single bolt 257. In the case of a tiled display wall comprising n*m display blocks 500 and (n+1)*(m+1) alignment mechanisms 32, at least two of the four holes G211, G221, G231, and G241 of each alignment mechanism 32 at the outer periphery of the tiled display wall are not used to hold the support structure 10 in place. When other support structures 10 are added to the tiled display wall, these at least two of the four holes are used.

[0162] The tiled display can be connected to the support structure disclosed above. The alignment mechanism 32 can be used with a support substructure 33 for securing the display piece 500 to the support structure of the tiled display, the support substructure 33 being characterized in that it is connected to the support structure by means of a first mechanism that allows the display piece to move independently of the presence or absence of adjacent display pieces in a plane parallel to the nominal plane XY of the tiled display. The alignment mechanism 32 can be used in conjunction with support substructures 33, each of which is used to fasten the display pieces 500 to the support structure of the tiled display, wherein adjacent display pieces in the tiled display are separated by a nominal seam. The support substructure 33 is characterized in that it is connected to the support structure by means of a first mechanism and a second mechanism, the first mechanism allowing each display piece to move in a plane parallel to the nominal plane XY of the tiled display to form a gap G between adjacent display pieces by moving one or more display pieces from a first position P1 to a second position P2, the second mechanism fixing the position of at least one support substructure 33 in the second position, wherein the gap G is larger than the nominal seam.

[0163] Alignment mechanism 32 can be used with a first mechanism, which may be driven by, for example, a motor or a manual crank or key. The first mechanism may include means for converting rotational motion into translation of at least one support substructure. When the first mechanism includes a sector gear 312 and a pin 311, alignment element 32 can be used with the first mechanism, the sector gear being used to apply force on the support substructure 33 via the pin 331. When the first mechanism includes a guiding means for assisting in controlling the direction and / or amplitude of movement of the support substructure, alignment element 32 can be used with the first mechanism. Alignment element 32 can be used with a release mechanism. Alignment element 32 can be used with display pieces having one or more contact elements 510, 520, 530, and 540 for applying force on adjacent display pieces. The contact elements can be used to provide self-alignment when the pieces are as close as possible to each other. Alignment element 32 can be used with a second mechanism that can fix the position of at least one support substructure 33. The second structure may include a rod or hammer 316 and a pin 332 fastened to a support substructure. The rod or hammer 316 may be in two positions: in a first position H1, the hammer does not prevent the free movement of the pin 332, and in a second position H2, the hammer prevents the free movement of the pin 332. The alignment element 32 may be used with a display block 500, which is fastened to or engaged with another support substructure 33 via a third support substructure 34, which includes a mechanism for moving the display block outside the display plane XY.
