     BACKGROUND 
     Some modular display systems provide visual variety to a display experience. However, current systems are often limited in their ability to maximize deliverable visual variety. For example, current modular display panel systems are often limited by flat, rectilinear modular units. 
     Current improvements to existing personal HDTVs that provide a curved viewing experience, may increase viewer immersion by engaging peripherals, may increase viewer focus by conforming more to the shape of the eye, and may increase viewer perception by improving the direction of emitted light. Although many of these and other improvements are desirable as applied to modular display systems, opportunities for curved, large-scale modular display systems are limited or non-existent. 
     Therefore, it is desirous to obtain or otherwise improve upon modular display systems, methods, and/or apparatuses to provide improvements to a viewer&#39;s visual experience by enabling a curved, large-scale modular display system. 
     SUMMARY 
     In one aspect, the inventive concepts disclosed herein are directed to an angle setter apparatus for establishing curvature for a modular display system. The angle setter apparatus may include an angled support having a first side, a second side, and a predetermined angle. The predetermined angle may be proportional to an angle of separation between two or more modular units of a modular display system. The angled support may include one or more alignment pins protruding from the first side of the angled support. The angled support may include one or more fasteners configured to be accessed from the second side of the angled support in order to couple the first side of the angled support to a surface of a first modular unit of the modular display system and to a surface of a second modular unit of the modular display system. The angle setter may link the first modular unit and the second modular unit together the first modular unit and the second modular unit are linked together to provide an overall angle or an overall curvature to the modular display system. 
     In another aspect, the inventive concepts disclosed herein are directed to a system for providing an angle of curvature for a modular display system. The system may include multiple modular units and an interlocking sub-system, the multiple modular units may be interconnected or interlocked by the interlocking sub-system to form a modular display system. The interlocking sub-system may include one or more angle setters, an alignment bar, and a channel. The one or more angle setters may be configured to provide a predetermined angle for enabling or providing curvature to the modular display system. The channel may be configured to receive the alignment bar and allow the alignment bar to rotate or move as two or more modular units are separated to enable or provide the predetermined angle to the modular display system. 
     In another aspect, the inventive concepts disclosed herein are directed to a modular display system with an angle of curvature. The modular display system includes a modular support frame with one or more modular units. The modular display system includes an interlocking sub-system. The interlocking sub-system may include one or more angle setters for providing the angle of curvature to a modular display system according to a predetermined angle. The modular display system further includes a power supply and a display panel. The display panel may include one or more modular units, and may be configured to interface with the power supply and a controller to receive power and display input. Two or more modular units of the modular support frame or two or more modular units of the display panel may be coupled together using the interlocking sub-system to form the modular display system.

     DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
     Before explaining at least one embodiment of the inventive concepts disclosed herein in detail, it is to be understood that the inventive concepts are not limited in their application to the details of construction and the arrangement of the components or steps or methodologies set forth in the following description or illustrated in the drawings. In the following detailed description of embodiments of the instant inventive concepts, numerous specific details are set forth in order to provide a more thorough understanding of the inventive concepts. However, it will be apparent to one of ordinary skill in the art having the benefit of the instant disclosure that the inventive concepts disclosed herein may be practiced without these specific details. In other instances, well-known features may not be described in detail to avoid unnecessarily complicating the instant disclosure. The inventive concepts disclosed herein are capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and is not meant to be limiting. 
     Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by anyone of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present). 
     Reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. 
     “Large-scale” as used herein with respect to a display system means multiple (e.g., two or more) display units linked together to form a single display system. 
     “Small-scale” as used herein means a single modular display unit, or less (e.g., one or more display panels that are not a part of a group of display panels) to form a separate visual aspect of a modular interlocking display system. 
     Broadly, interlocking systems, methods, and apparatuses are disclosed for providing an angle or a curvature to a modular display system. In an exemplary embodiment, the interlocking system is designed for both small- and large-scale use, and is configurable to enable almost any visual arrangement for a modular display system. The desired angle or curvature of the system may be supplied by one or more angle setters, enabling in-part a convex curvature, a concave curvature, an obtuse angle, or an acute angle of the modular display system. The curved or angled viewing experience, may increase viewer immersion by engaging peripherals, may increase viewer focus by conforming more to the shape of the eye, or may increase viewer perception by improving the direction of emitted light. In this regard, support frames of display panels or segments of a segmented display panel may be separated, and when the emissive portion of the display panel is flexible, slight curvature is obtained. When separate display panels are incorporated on respective separated portions, then an angled display system is obtained. 
     Referring now to  FIG. 1 , a block diagram of a modular display system  100  is depicted. In an exemplary embodiment, system  100  may include a modular support frame  102 , an interlocking sub-system  104 , one or more display panels  106 , one or more interfaces (e.g., power supply, data input/output, etc.)  108 , and a controller  110  communicatively coupled with the one or more interfaces  108 . 
     Referring now to  FIG. 2 , a more detailed perspective view of system  100  is depicted. The system  100  may include two modular units  102   a  and  102   b  separated according to an acute angle to provide an overall obtuse angle to the modular display system  100 . It is noted that the overall obtuse angle of the system  100  depicted in  FIG. 1  is not limiting, as the system  100  could be depicted as having an acute angle, a concave curvature, or a convex curvature, each of which is intended to be encompassed by the inventive concepts of the present disclosure. 
     In an exemplary embodiment, the display panel  106  includes a light emitting diode (e.g., LED or OLED) display panel. In other embodiments, other display panels may be used including, but not limited to, a liquid crystal display (LCD) panel. 
     In embodiments, the display panel  106  includes a single flexible display panel (e.g., organic light emitting diode (OLED) or other flexible panel material) that spans two modular units. The single flexible display panel may be flexed according to a desired amount of curvature or according to an angle of separation between separated modular units. For example, the angle of separation may be a small or slight separation and may be from a range of angles of separation, including, but not limited to, from 0.5° to 2.5° or from 2.5° to 5.0° degrees of separation, inclusive. It is noted that in some embodiments, almost any angle or any angle of separation may be achievable. 
     In other embodiments, the display panel  106  includes multiple display panels to span a single modular support unit (e.g.,  102   a ), each of which may be slightly separated to provide one or more angles to the modular display system  100  and may be configured to be viewed as a single display. For example, referring again to  FIG. 2 , the two modular units  102   a  and  102   b  may be support frames that are slightly separated and each modular unit may have its own display panel  106  that is configured with controller  110  such that when viewed, a viewer sees each of the multiple panels as a single panel despite the slight angle existing between respective display panels of the multiple display panels. 
     In some embodiments, the display panel  106  includes multiple segments to form a segmented display panel providing additional benefits that come from another degree of modularity. For example, each segment of the segmented display panel may be hot-swappable. 
     In an exemplary embodiment, the display panel  106  may include a display panel that is modified or retrofitted according to the inventive concepts disclosed herein. For example, a display panel may include one of an LCD, LED, OLED, or other known display panel known in the art that has holes formed in a support structure of the display panel to coincide with one or more fasteners, pins, or connection points (e.g., mounts, brackets, screws, bolts, threaded holes, etc.) of the interlocking sub-system  104 . 
     In an exemplary embodiment, the display panel  106  includes a weather-proof panel. For example, an embodiment of the modular panels may be rated with an Ingress Protection Marking, or IP Code rating, of IP65 (e.g., from any direction rated at IP65). 
     In an exemplary embodiment, a display panel  106  may be sized to cover multiple modular units. For example, the display panel  106  may include a first half of support portion (e.g.,  102   a , below), a second half of a support portion ( 102   b , below), and a flexible LED tile positioned on a front surface of the support portions, may cover the entire surface (e.g., covers both the first half and the second half). 
     In an exemplary embodiment, the number of pixels within an LED tile of a display panel  106  may vary. For example, the number of pixels may include from 128×32, 96×24, 64×16 and/or 48×12 (e.g., with pixel densities respectively including 11,377 pix/sqm, 6,400 pix/sqm, 2,844 pix/sqm, and 1,600 pix/sqm). 
     In an exemplary embodiment, the controller  110  utilizes a first one or more communication links to communicate information to display panel  106  by way of the one or more interfaces  108 . For example, the first one or more communication links may include an electrical, an optical, a wired, or a wireless communication link, and combinations thereof. In this regard, the one or more interfaces  108  may include a user input device, a display driver, a data link, or a bi-directional port, and combinations thereof, to relay information such as user input or rendering information to the display panel  106 . The controller  110  may utilize a second one or more communication links to connect the controller and the I/O interface(s) to a network, including but not limited to, a Local Area Networks (LAN) (e.g., an Ethernet or corporate network), a Wide Area Network (WAN) (e.g., the Internet), a wireless data network, a fiber optical network, a radio frequency communications network, another electronic data network, or combinations thereof. 
     Referring again to  FIG. 2 , the modular support frame  102  may include a first modular unit  102   a  and a second modular unit  102   b  that are interconnected via the interlocking sub-system  104  to form the modular support frame  102 . In embodiments, the modular support frame  102  may be made up of one or more of a rigid, semi-rigid, and flexible material. For example, the modular units  102   a  and  102   b  may be made up of the rigid material, which may be designed for light-weight, high-tensile strength. For instance, the rigid material may include, but is not limited to, A356 T6 aluminum, A201 T7 aluminum, A295 T6 or T62 aluminum, A328 T6 aluminum, A355 T71 aluminum, A771 T71 aluminum, other aluminum alloys, magnesium alloys, titanium alloys, beryllium alloys, carbon fiber materials (e.g., carbon fibers derived from polyacrylonitrile (PAN), reinforced carbon carbon (RCC), carbon-fiber-reinforced polymer (CFRP), carbon-fiber-reinforced plastic (CRP), carbon-fiber-reinforced thermoplastic (CFRTP), or combinations thereof), or combinations thereof. 
     In embodiments, the interlocking sub-system  104  includes an alignment bar  104   a  and an alignment plate  104   b . The alignment bar  104   a  may be configured to be received by an alignment plate (not shown) of another modular support frame and the alignment bar plate  104   b  may be configured to receive an alignment bar (not shown) of another modular support frame. 
     In embodiments, the alignment bar  104   a  may be flanged and may include multiple alignment bars. In some embodiments, the multiple alignment bars include at least a first alignment bar that is orthogonal to a second alignment bar. 
     In embodiments, the alignment plate  104   b  may be channeled to allow movement of the alignment bar  104   a  in the channel. For example, a channel  112  of the alignment plate  104   b  may be curved to allow for movement of the flange of the alignment bar  104   a  along the channel according to a desired angle of separation between modular units of system  100 . For instance, the modular units  102   a  and  102   b  may be initially interconnected without any curvature, or substantially in a flat or straight-lined configuration, but when the two modular units  102   a  and  102  are slightly separated along a vertical connection line at the back of the system  100 , the curved channel  112  may allow for the alignment bar  104   a  to move to provide the slight separation according to the desired separation angle of system  100 . 
     In some embodiments, the alignment plate  104   b  is formed with a hole therein in communication with the channel  112 . The hole may be slightly larger than the flange of the flanged alignment bar  104   a  in order to allow insertion of the flanged alignment bar  104   a  into the channeled plate  104   b.    
     In an exemplary embodiment, the interlocking sub-system  104  includes an angle setter  104   c . Referring now to  FIGS. 2 and 3 , the angle setter  104   c  may have a predetermined shape including a predetermined angle, psi (ψ)  114 , and may be integrated with the modular units  102   a  and  102   b  of system  100 . For example, the angle setter  104   c  may be coupled to each of the two modular units  102   a  and  102   b  using one or more fasteners  116  and one or more co-located alignment pins  118  (see  FIG. 7 ). In some embodiments, fasteners  116  and the pins  118  are co-located with respect to a surface of the angle setter  104   c  from which they protrude, they are co-located with respect to a modular unit (e.g.,  102   b ) with which they interface, or combinations thereof. For example, a first set of pins may be co-located on a first surface of the angle setter  104   c  and a second set of pins may be co-located on a second surface. The first set and the second set of pins  118  may be symmetrically separated from each other on a first side of the angle setter  104   c.    
     In some embodiments, the angle, psi (ψ)  114 , of the angle setter  104   c  may depend on, or at least be proportional to, an angle of separation, phi (Φ)  120 , between modular units. For example, if the angle setter  104   c  has an angle, psi (ψ)  114 , then an angle of separation between one or more modular units, phi (Φ)  120 , may be related according to the following: 
       Φ≈180−ψ  (1)
 
     In some embodiments, the angle, psi (ψ)  114 , of the angle setter  104   c  may depend on, or at least be proportional to, a display arc  122 , or its center angle, theta (θ)  124 , and a radius of curvature  126 . For example, the desired center angle  124  of the display arc  122  (e.g., theta (θ)), may be related to the radius of curvature  126  according to the following: 
         L≈ 2 R  cos(½θ)  (2)
 
         L ≈√{square root over (2 a   2 −2 a   2  cos(180−Φ))}  (3)
 
     such that when an operator decides on the desired radius of curvature  126  and/or the desired center angle  124  of the display arc  122 , then one can solve for L using relationship (2), and thereby solve for phi (Φ)  120  and psi (ψ)  114  using relationships (1) and (3). It is noted that the display arc  122  may represent an arc that approximates a viewer experience of display system  100  resulting from interconnected modular units (e.g., segmented display panels or support frames). 
     In other embodiments, the angle, psi (ψ)  114 , may depend on, or at least be proportional to, a desired angle, omega (ω) that is proportional to a number of modular units, N, used in assembling the modular display system  100 . For example, if the desired shape of the display system  100 , at least with respect to interconnected frames  102 , resembles that of a polygon or a portion of a polygon, then the angle, omega (ω), may be proportional to N modular display units (e.g., support frames  102 ), where N is greater than two, as follows:

     In some embodiments, the angle omega (ω) may be proportional to, or substantially equivalent to, the separation angle, phi (Φ)  120 . 
     In an exemplary embodiment, the angle, psi (ψ)  114  of the angle setter  104   c  may be created by machining a rigid support, a rigid bracket, or a rigid brace (e.g., via facial milling) to have one or more portions removed from a side of the rigid support to create the angle. For example, referring now to  FIG. 7 , a first facial portion may be milled to remove first material and create the slope of surface  128 , and a second facial portion may be milled to remove second material and create the slope of surface  130 . It is noted that in some embodiments, the milling of surfaces  128  and  130  may occur simultaneously. 
     In an exemplary embodiment, the one or more fasteners  116  and the one or more pins  118  of the angle setter  104   c  may be orthogonal to a plane of a surface from which they protrude. In this regard, the angle setter  104   c  may include at least two surfaces that have equal but opposite (e.g., opposite in sign) slopes. For instance, the angle setter  104   c  of  FIG. 7  depicts a first surface  128  on a first side of the angle setter  104   c  that has a first slope and a second surface  130  on the same side that has a second slope, where the second slope is equal but opposite to the first slope. 
     In an exemplary embodiment the one or more fasteners  116  include multiple fasteners (e.g., two), and the one or more pins  118  includes multiple pins (e.g., four). 
     In some embodiments, the angle, psi (ψ)  114  of the angle setter  104   c  may be formed by forming a line along a center-axis of a facial surface of the rigid support and bending each side of the rigid support along the line to create the angle. For example, the line may be cut, scored, etched, or otherwise formed in the facial surface. In this regard, the line may form a trough having two sloping or angled sides, where the bending is permitted until the two sloping or angled sides meet. 
     In some embodiments, the angle setter  104   c  may be made up of two or more materials. The first material being a rigid material comprising steel, aluminum, carbon fiber, a rigid polymer-based fiber, a metal alloy, or combinations thereof, to create a back-support for the angle setter  104   c . The second material may be rigid, semi-rigid (epoxy-based), or flexible (e.g., rubber, elastomer, elastomeric polymer, etc.), and may be molded, cast, or otherwise formed onto the back-support to create, provide in-part, or enable the angle of the angle setter  104   c . In other embodiments, the flexible material may be formed onto the back-support to increase protection, increase gripping, or reduce slipping between surfaces of the angle setter  104   c  and surfaces of a modular unit. 
     In embodiments, the angle setter  104   c  may be of different sizes and/or angles depending on a location for which it is intended for use within the modular display system  100 . For example, a first set (e.g., two or more) of angle setters  104   c  may be used to connect two or more segments of a segmented display panel  106 , where each segment is a modular unit. By way of another example, a second set of angle setters  104   c  may be used to connect two support frames, where each of the two support frames is a modular unit. By way of yet another example, the first and second sets may be used in combination with each other to provide a modular display system that incorporates angled segmented display panels and angled support frames interconnected by the angle setter  104   c . In this regard, if a first angle setter  104   c  of the first set is intended to be used to establish an angle of the segmented display panel, then it may have a relatively small size such that it may be integrated with a panel having combined dimensions of 100 mm×500 mm (e.g., a first half of the panel may be 100 mm×250 mm and a second half of the panel may be 100 mm×250 mm). If a second angle setter  104   c  of the second set is intended to be used to connect two or more support frames (e.g., each frame having a size of 1000 mm×1000 mm×145 mm), then a size of the second angle setter may be relatively larger than the first angle setter. Because embodiments may vary in sizes, exemplary embodiments disclosed herein may maintain a width to height ratio of the angle setter  104   c . For example, the width to height ratio may include a ratio of approximately 1:2. 
     In some embodiments, because a size and/or angle of the angle setter  104   c  may vary depending on where it is intended to be used in the system  100 , in some embodiments the angle setter  104   c  may include an identifier  132 . The identifier  132  may include an imprinted number or label formed in the angle setter  104   c , where the imprinted number or label may include at least the angle psi (ψ)  114  of the angle setter  104   c . For example, referring now to  FIG. 9 , an angle setter  104   c  is depicted with an identifier  132  to indicate a 5.0 degree angle corresponding to the angle of the angle setter  104   c . It is noted that although the identifier  132  is depicted as being associated with an exterior surface of the angle setter  104   c , other locations for the identifier  132  are contemplated herein. In this regard, the identifier  132  may be associated with an interior or front surface, a side surface, a top surface, a bottom surface, or combinations thereof. 
     In some embodiments, the interlocking sub-system  104  includes a bar and hooking configuration  134 . For example, referring now to  FIG. 10 , the system  100   a  may function similarly to system  100  except that system  100   a  may include the bar and hooking configuration for interlocking modular units and except that system  100   a  may include multiple display panel segments/portions  106   a - 106   d , with each display panel segment/portion  106   a - 106   d  having a handle for ease of removal or replacement of the respective display panel segment/portion. For instance, each display panel segment/portion  106   a - 106   d  may be hot-swappable. In some embodiments, the bar and hooking configuration  134  is used to interconnect or couple a first modular support unit including a first segmented display panel to a second modular support unit including a second segmented display panel. 
     In embodiments, the controller  110  is in communication with, or implemented within a computer. The computer may include one or more processors (e.g., field programmable gate array (FPGA), microprocessor, application specific integrated circuit (ASIC), etc.) and one or more memories (e.g., non-transitory memory, solid state memory, disc memory, or combinations thereof) with instructions thereon for performing one or more processes disclosed herein. 
     It is noted that although  FIGS. 1 and 10  depict specific modular configurations of system  100  and system  100   a , other modular configurations are contemplated and encompassed by the inventive concepts of the present disclosure. For example,  FIG. 1  depicts a modularity that includes a modular unit corresponding with single display panel support frames (e.g.,  102   a  and  102   b ) and includes a large-scale modularity that corresponds with two or more interlocked support frames (e.g.,  102   a  and  102   b ). It is further noted that this depiction is merely for illustrative purposes. By way of another example, a modularity may include a segmented display panel such that a modular unit includes two segments of the display panel interconnected by a small or small-scale angle setter  104   c . Those skilled in the art will recognize other modularity configurations corresponding to the inventive concepts disclosed herein, each of which are intended to be encompassed. 
     In embodiments, the support portion (e.g., support frame  102 ) of system  100  may include multiple similar, if not identical (e.g., for ease of manufacturing), support modular units. In some embodiments, the near-identical support modular units are support halves. In other embodiments, the near-identical support modular units may include more than two halves (e.g., may include three, four, or more support segments, etc.) with an input/output (I/O) port located on each segment of the multiple support segments. In other embodiments, only two segments of the support segments have I/O ports located thereon. In some embodiments, only one support modular unit of the multiple support modular units includes an I/O port, and the multiple support segments may be interconnected with wires, or other electronic communication means. 
     It is to be understood that embodiments of the methods according to the inventive concepts disclosed herein may include one or more of the steps described herein. Further, such steps may be carried out in any desired order and two or more of the steps may be carried out simultaneously with one another. Two or more of the steps disclosed herein may be combined in a single step, and in some embodiments, one or more of the steps may be carried out as two or more sub-steps. Further, other steps or sub-steps may be carried in addition to, or as substitutes to one or more of the steps disclosed herein. 
     From the above description, it is clear that the inventive concepts disclosed herein are well adapted to carry out the objects and to attain the advantages mentioned herein as well as those inherent in the inventive concepts disclosed herein. While presently preferred embodiments of the inventive concepts disclosed herein have been described for purposes of this disclosure, it will be understood that numerous changes may be made which will readily suggest themselves to those skilled in the art and which are accomplished within the broad scope and coverage of the inventive concepts disclosed and claimed herein.
