Detailed Description
Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. Flowever, this disclosure may be embodied in many different forms and should not be construed as limited to the
embodiments set forth herein. Ranges can be expressed herein as from "about" one particular value, and/or to "about" another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.
Directional terms as used herein (for example, up, down, right, left, front, back, top, bottom, vertical, horizontal) are made only with reference to the figures as drawn and are not intended to imply absolute orientation.
Unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order, nor that with any apparatus, specific orientations be required.
Accordingly, where a method claim does not actually recite an order to be followed by its steps, or that any apparatus claim does not actually recite an order or orientation to individual components, or it is not otherwise specifically stated in the claims or description that the steps are to be limited to a specific order, or that a specific order or orientation to components of an apparatus is not recited, it is in no way intended that an order or orientation be inferred, in any respect. This holds for any possible non-express basis for interpretation, including: matters of logic with respect to arrangement of steps, operational flow, order of components, or orientation of components; plain meaning derived from grammatical organization or punctuation, and; the number or type of embodiments described in the specification.
As used herein, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Thus, for example, reference to "a" component includes aspects having two or more such components, unless the context clearly indicates otherwise.
Referring to Figs. 1A, 1 B, an exemplary display tile 100 is schematically depicted. More specifically, Fig. 1 A schematically depicts a front plan view of an example of display tile 100, and Fig. 1 B schematically depicts a back plan view of an example of display tile 100. Display tile 100 includes a substrate 110, a plurality of light sources 180, and drive circuitry or control electronics 190.
In the depicted example, substrate 110 has a first surface 112 (Fig. 1A) and a second surface 114 (Fig. 1 B) opposite first surface 112, with light sources 180 provided on first surface 112 and control electronics 190 provided on second surface 114. In examples, first surface 112 represents a front or first side 102 of display tile 100, and second surface 114 represents a back or second side 104 of display tile 100.
Light sources 180 may be arranged, for example, in an array including any number of rows and columns. Each light source 180 is electrically coupled to drive circuitry, such as drive circuitry or control electronics 190, for driving or controlling operation of each light source 180. Each light source 180 may include, for example, a light emitting diode (LED), a microLED, an organic light emitting diode (OLED), or other suitable light source. Fig. 2A and Figs. 2B, 2C schematically depict a back view and edge views, respectively, of an example of a support structure 200 for a display tile, such as display tile 100 (Figs. 1A, 1 B). In addition, Fig. 3 schematically depicts an exploded view of an example of support structure 200. In examples, support structure 200 includes a foundational tile 210, standoffs 220, flanges 230, and magnetic elements 240. As disclosed herein, foundational tile 210 may support one or more display tiles, such as one or more display tiles 100 (Figs. 1 A, 1 B).
In addition, standoffs 220, flanges 230, and magnetic elements 240 may be used to join or interlock multiple support structures 200 together and/or secure or join other elements to support structure 200 or support structure 200 from other elements.
In the depicted example, foundational tile 210 has a first surface 212 and a second surface 214 opposite first surface 212. In addition, foundational tile 210 has edge surfaces or edges 216 extended between first surface 212 and second surface 214. In the depicted example, edge surfaces or edges 216 of foundational tile 210 include first, second, third, and fourth edges 2161 , 2162, 2163, and 2164, with first and third edges 2161 and 2163 of foundational tile 210 opposite each other, and second and fourth edges 2162 and 2164 of foundational tile 210 opposite each other. As such, second edge 2162 of foundational tile 210 is adjacent first edge 2161 , third edge 2163 of foundational tile 210 is adjacent second edge 2162, fourth edge 2164 of foundational tile 210 is adjacent third edge 2163, and first edge 2161 of foundational tile 210 is adjacent fourth edge 2164.
In examples, first surface 212 and second surface 214 of foundational tile 210 are substantially planar and substantially parallel with each other, and edge surfaces or edges 216 of foundational tile 210 are substantially orthogonal to first surface 212 and second surface 214. In examples, first surface 212 represents a front or first side of support structure 200 and surface 214 represents a back or second side of support structure 200. As such, first surface 212 supports one or more display tiles, such as one or more display tiles 100, as disclosed herein.
In the depicted example, foundational tile 210 has a substantially rectangular shape. In other examples, foundational tile 210 may have other suitable shapes, such as, for example, other polygonal shapes.
In at least one example, foundational tile 210 is comprised of glass. In examples, the glass is precise with regards to dimensions (length, width, and thickness) and flatness. In examples, the glass has a coefficient of thermal expansion (CTE) similar to or substantially matching a CTE of a supported display tile, such as display tile 100. An example of such glass includes EAGLE XG glass by Corning. In other examples, a lower cost glass, such as soda lime glass, may be used. In examples, the glass is tempered for robustness, including, for example, thermally tempered based upon an air bearing to maintain better flatness.
In the depicted example, standoffs 220 are positioned on first surface 212 of foundational tile 210 adjacent respective edges 216 of foundational tile 210. For example, first, second, third, and fourth standoffs 2201 , 2202, 2203, and 2204 are positioned on first surface 212 of foundational tile 210 adjacent respective first, second, third, and fourth edges 2161 , 2162, 2163, and 2164 of foundational tile 210.
In the depicted example, standoffs 220 are inset from respective edges 216 of foundational tile 210. In other examples, standoffs 220 may be flush with or aligned with edges 216 of foundational tile 210.
Although depicted as including four standoffs 220, in other examples, support structure 200 may include other numbers of standoffs 220. For example, support structure 220 may include multiple standoffs 220 positioned along one or more edges 216 of foundational tile 210.
In at least one example, standoffs 220 are comprised of a material having a CTE similar to or substantially matching a CTE of foundational tile 210. In an example where foundational tile 210 is comprised of soda lime glass, standoffs 220 may be comprised of a fiberglass material, such as, for example, ULTREX fiberglass by Marvin Windows. In one example, standoffs 220 are secured to foundational tile 210 by epoxy, such as, for example, 3M Glass Adhesive 18051.
In the depicted example, flanges 230 extend from select standoffs 220. More specifically, flanges 230 extend from respective standoffs 220 positioned along adjacent edges 216 of foundational tile 210. For example, first and second flanges 2301 and 2302 extend from respective first and second standoffs 2201 and 2202 positioned along respective adjacent edges 2161 and 2162 of foundational tile 210.
In the depicted example, flanges 230 extended from respective standoffs 220 beyond adjacent edges 216 of foundational tile 210. As such, flanges 230 are cantilevered from standoffs 220 and, more specifically, are cantilevered from foundational tile 210.
Although depicted as including two flanges 230, in other examples, support structure 200 may include other numbers of flanges 230. For example, support structure 200 may include multiple flanges 230 extended from
respective standoffs 220 positioned along one or more adjacent edges 216 of foundational tile 210.
In at least one example, flanges 230 are comprised of a material having a CTE similar to or substantially matching a CTE of foundational tile 210. In an example where foundational tile 210 is comprised of soda lime glass, flanges 230 may be comprised of a fiberglass material, such as, for example, ULTREX fiberglass by Marvin Windows. In one example, flanges 230 are secured to standoffs 220 by epoxy, such as, for example, 3M Glass Adhesive 18051. Although depicted as separate elements, in other examples, standoffs
220 and flanges 230 may be integrally formed (i.e. , formed as a unitary member).
In the depicted example, magnetic elements 240 are on respective flanges 230 positioned along adjacent edges 216 of foundational tile 210 and on respective standoffs 220 positioned along other adjacent edges 216 of foundational tile 210. For example, magnetic elements 240 are included on, embedded in, or integrated with flanges 2301 , 2302 positioned along adjacent edges 2161 , 2162 of foundational tile 210, and are included on, embedded in, or integrated with standoffs 2203, 2204 positioned along other adjacent edges 2163, 2164 of foundational tile 210.
As disclosed herein, magnetic elements 240 may be used to join or interlock multiple support structures 200 together and/or secure or join other elements to support structures 200 or support support structures 200 from other elements. In at least one example, foundational tile 210 of support structure 200 is formed by substrate 110 of display tile 100 (Figs. 1A, 1 B) such that substrate 110 of display tile 100 comprises foundational tile 210 of support structure 200. As such, standoffs 220 and flanges 230 (with magnetic elements 240), as described herein, are on second surface 114 of substrate 110. Fig. 4 schematically depicts a plan view of an example of a plurality of support structures 200 arranged in an array. For example, four support structures 200, each including foundational tile 210, standoffs 220, flanges 230, and magnetic elements 240, as described above, are arranged in a 2x2 array such that one or more flanges 230 of respective support structures 200 overlap standoffs 220 of respective adjacent support structures 200. More specifically, in the depicted example, first, second, third, and fourth support structures 2001 , 2002, 2003, and 2004 are arranged in a 2x2 array such that flange 2301 of second support structure 2002 overlaps standoff 2203 of first support structure 2001 , flange 2302 of third support structure 2003 overlaps standoff 2204 of first support structure 2001 , flange 2301 of fourth support structure 2004 overlaps standoff 2203 of second support structure 2002, and flange 2302 of fourth support structure 2004 overlaps standoff 2204 of third support structure 2003.
In examples, when multiple support structures 200 are arranged in an array, magnetic elements 240 of respective overlapping flanges 230 and standoffs 220 are magnetically coupled with each other. For example, in the depicted example, when first, second, third, and fourth support structures 2001 , 2002, 2003, and 2004 are arranged in the 2x2 array, magnetic elements 240 of flange 2301 of second support structure 2002 magnetically couple with magnetic elements 240 of standoff 2203 of first support structure 2001 , magnetic elements 240 of flange 2302 of third support structure 2003
magnetically couple with magnetic elements 240 of standoff 2204 of first support structure 2001 , magnetic elements 240 of flange 2301 of fourth support structure 2004 magnetically couple with magnetic elements of standoff 2203 of second support structure 2002, and magnetic elements 240 of flange 2302 of fourth support structure 2004 magnetically couple with magnetic elements 240 of standoff 2204 of third support structure 2003. As such, first, second, third, and fourth support structures 2001 , 2002, 2003, and 2004 are joined together or interlocked with each other. Although four support structures 200 are depicted as being arranged in an array, in other examples, other numbers of support structures 200 may be arranged in an array. In addition, although support structures 200 are depicted as being arranged in a 2x2 array, in other examples, support structures 200 may be arranged in other arrays (e.g., 3x2, 3x3, 4x4). As such, tiled displays of different sizes may be established. Figs. 5A, 5B, 5C, 5D, 5E, 5F schematically depict plan views of an example of arranging and supporting a plurality of support structures 200, such as, for example, first, second, third, and fourth support structures 2001 , 2002, 2003, and 2004, in an array. In examples, one or more support structures 200 may be supported by one or more rails 300. In examples, rails 300 help to position support structures 200 in-plane with each other, square and plumb.
In the example depicted in Fig. 5A, rails 300 include a lower or bottom rail 301 , side rails 302, 303, and an upper or top rail 304. In examples, rails 300 include respective magnetic elements 340 that correspond with magnetic elements 240 of support structures 200, including, more specifically, magnetic elements 240 of standoffs 220 and flanges 230 of support structures 200 (e.g., Fig. 2A, Fig. 4). As such, as disclosed herein, support structures 200 may be supported by and magnetically coupled with one or more of rails 300. In examples, one or more of rails 300 may be secured to, mounted on, or include supports that are secured to, mounted on, or extend from another structure, such as, for example, a wall, frame, post, stanchion or other support.
In one example, as depicted in Fig. 5B, bottom rail 301 and side rail 302 are positioned, and a support structure 200, such as, for example, first support structure 2001 , is positioned to contact bottom rail 301 and side rail 302. As such, magnetic elements 240 of first support structure 2001 , including, more specifically, magnetic elements 240 of flanges 230 of first support structure
2001 , magnetically couple with respective magnetic elements 340 of bottom rail
301 and side rail 302. In one example, contact with bottom rail 301 and side rail
302 establishes x- and y-positions of first support structure 2001 , and magnetic coupling of flanges 230 with bottom rail 301 and side rail 302 establishes a z- position of first support structure 2001. In one example, as depicted in Fig. 5C, another support structure 200, such as, for example, second support structure 2002, is positioned to contact bottom rail 301 and first support structure 2001 , including, more specifically, an edge of first support structure 2001. Thus, in one example, an edge of second support structure 2002 abuts an adjacent edge of first support structure 2001 , and a respective flange 230 of second support structure 2002 overlaps an adjacent standoff 220 of first support structure 2001 (Fig. 5B). As such, magnetic elements 240 of second support structure 2002, including, more specifically, magnetic elements 240 of flanges 230 of second support structure 2002, magnetically couple with respective magnetic elements 340 of bottom rail
301 and respective magnetic elements 240 of adjacent standoff 220 of first support structure 2001 (Fig. 5B). In one example, contact with bottom rail 301 and first support structure 2001 establishes x- and y-positions of second support structure 2002, and magnetic coupling of flanges 230 with bottom rail 301 and first support structure 2001 establishes a z-position of second support structure 2002.
In one example, as depicted in Fig. 5D, another support structure 200, such as, for example, third support structure 2003, is positioned to contact side rail 302 and first support structure 2001 , including, more specifically, an edge of first support structure 2001. Thus, in one example, an edge of third support structure 2003 abuts an adjacent edge of first support structure 2001 , and a respective flange 230 of third support structure 2003 overlaps an adjacent standoff 220 of first support structure 2001 (Fig. 5C). As such, magnetic elements 240 of third support structure 2003, including, more specifically, magnetic elements 240 of flanges 230 of third support structure 2003, magnetically couple with respective magnetic elements 340 of side rail 302 and respective magnetic elements 240 of adjacent standoff 220 of first support structure 2001 (Fig. 5C). In one example, contact with side rail 302 and first support structure 2001 establishes x- and y-positions of third support structure 2003, and magnetic coupling of flanges 230 with side rail 302 and first support structure 2001 establishes a z-position of third support structure 2003. In one example, as depicted in Fig. 5E, another support structure 200, such as, for example, fourth support structure 2004, is positioned to contact second support structure 2002 and third support structure 2003, including, more specifically, an edge of second support structure 2002 and an edge of third support structure 2003. Thus, in one example, an edge of fourth support structure 2004 abuts an adjacent edge of second support structure 2002 and a respective flange 230 of fourth support structure 2004 overlaps an adjacent standoff 220 of second support structure 2002 (Fig. 5D), and an edge of fourth support structure 2004 abuts an adjacent edge of third support structure 2003 and a respective flange 230 of fourth support structure 2004 overlaps an adjacent standoff 220 of third support structure 2003 (Fig. 5D). As such, magnetic elements 240 of fourth support structure 2004, including, more specifically, magnetic elements 240 of flanges 230 of fourth support structure 2004, magnetically couple with respective magnetic elements 240 of adjacent standoff 220 of second support structure 2002 (Fig. 5D) and respective magnetic elements 240 of adjacent standoff 220 of third support structure 2003 (Fig. 5D). In one example, contact with second support structure 2002 and third support structure 2003 establishes x- and y-positions of fourth support structure 2004, and magnetic coupling of flanges 230 with second support structure 2002 and third support structure 2003 establishes a z-position of fourth support structure 2004.
In one example, as depicted in Fig. 5F, top rail 304 and side rail 303 are positioned to contact respective support structures 200, such as, for example, third support structure 2003 and fourth support structure 2004, and second support structure 2002 and fourth support structure 2004. As such, respective magnetic elements 240 of third support structure 2003 and fourth support structure 2004 and respective magnetic elements 240 of second support structure 2002 and fourth support structure 2004, including, more specifically, magnetic elements 240 of respective standoffs 220 of third support structure 2003 and fourth support structure 2004 (Fig. 5E) and magnetic elements 240 of respective standoffs 220 of second support structure 2002 and fourth support structure 2004 (Fig. 5E), magnetically couple with respective magnetic elements 340 of top rail 304 and respective magnetic elements 340 of side rail 303.
In at least one example, rails 300 are comprised of a material having a CTE similar to or substantially matching a CTE of foundational tile 210. In an example where foundational tile 210 is comprised of soda lime glass, rails 300 may be comprised of a fiberglass material, such as, for example, ULTREX fiberglass by Marvin Windows. In other examples, rails 300 may be comprised of metal.
Fig. 6 schematically depicts an edge view of an example of supporting a plurality of support structures 200, such as, for example, an edge view of an example of supporting first, second, third, and fourth support structures 2001 , 2002, 2003, and 2004 of Fig. 5F.
As depicted in the example of Fig. 6 (with side rail 302 removed for illustration purposes), bottom rail 301 includes a channel 305 to receive a respective flange 230 of a respective support structure 200, such as, for example, flange 230 of first support structure 2001. As such, in one example, magnetic elements 340 of bottom rail 301 are included along an adjacent sidewall 306 of channel 305. In addition, top rail 304 includes a flange 307 to support a respective standoff 220 of a respective support structure 200, such as, for example, standoff 220 of third support structure 2003. As such, in one example, magnetic elements 340 of top rail 304 are included along an adjacent surface 308 of flange 307.
As depicted in the example of Fig. 6, an edge of third support structure 2003 abuts an adjacent edge of first support structure 2001 , and a respective flange 230 of third support structure 2003 overlaps an adjacent standoff 220 of first support structure 2001. As such, magnetic elements 240 of third support structure 2003, including, more specifically, magnetic elements 240 of respective flange 230 of third support structure 2003, magnetically couple with respective magnetic elements 240 of adjacent standoff 220 of first support structure 2001. In one example, rails 300 are secured to, mounted on, or include supports that are secured to, mounted on, or extend from another structure, such as, for example, a wall, frame, post, stanchion or other support. For example, as depicted in Fig. 6, bottom rail 301 and top rail 304 are secured to a wall 10 with respective supports 350.
In one example, side rail 302 (e.g., Fig. 5A), similar to bottom rail 301 , includes a channel (not shown), similar to channel 305 of bottom rail 301 , to receive a respective flange 230 of a respective support structure 200, and includes one or more supports (not shown), similar to support 350 of bottom rail 301 , to secure side rail 302 to another structure, such as, for example, wall 10.
In addition, side rail 303 (e.g., Fig. 5A), similar to top rail 304, includes a flange (not shown), similar to flange 307 of top rail 304, to support a respective standoff 220 of a respective support structure 200, and includes one or more supports (not shown), similar to support 350 of top rail 304, to secure side rail 303 to another structure, such as, for example, wall 10.
In one example, as depicted in Fig. 6, surface 212 of foundational tile 210 is substantially planar with a respective front face or surface 309 of rails 300. In other examples, surface 212 of foundational tile 210 may be inset or recessed relative to a respective face or surface 309 of rails 300 or extend beyond a respective front face or surface 309 of rails 300.
Fig. 7 schematically depicts an edge view of an example of supporting a plurality of display tiles 500, as examples of display tile 100, with support structures 200 of Fig. 6. Similar to display tile 100, display tiles 500 include a substrate 510 having a first surface 512 and a second surface 514 opposite first surface 512, with light sources (not shown), such as light sources 180 (Fig. 1A), provided on first surface 512 and drive circuitry or control electronics (not shown), such as drive circuitry or control electronics 190 (Fig. 1 B), provided on second surface 514.
As depicted in the example of Fig. 7, display tiles 500 are supported by support structures 200 such that second surface 514 of a respective display tile 500 opposes and, in one example, contacts first surface 212 of foundational tile 210 of a respective support structure 200. In one example, magnets (not shown) may be included on second surface 514 of display tiles 500 and first surface 212 of support structures 200 to hold display tile 500 with a respective support structure 200.
Fig. 8 schematically depicts an exploded perspective view of an example of supporting display tile 500, as an example of display tile 100, with an example of support structure 200 (with standoffs 220 and flanges 230 removed for illustration purposes). In the depicted example, display tile 500 includes projections or pins 516, 518 extended from second surface 514 of substrate 510, and support structure 200 has a corresponding hole 206 and slot 208 formed in or through foundational tile 210 such that hole 206 is configured to receive pin 516 and slot 208 is configured to receive pin 518. As such, pins 516, 518 and hole 206 and slot 208 cooperate to establish a position of display tile 500 when display title 500 is supported by support structure 200.
In the depicted example, pins 516, 518 are positioned or arranged diagonally from each other, and hole 206 and slot 208 are positioned or arranged diagonally from each other. As such, with pin 516 inserted in hole 206, slot 208 allows for adjustment or variation of pin 518 within slot 208 such that a position of display tile 500 may be correspondingly adjusted or varied relative to support structure 200. Furthermore, slot 208 allows for the distance between pins 516, 518 to vary while still allowing positioning and supporting of display tile 500 on support structure 200.
In other examples, other holes or slots may be formed in or through foundational tile 210 to accommodate components of display tile 500 and/or facilitate access to or maintenance of display tile 500.
In one example, as depicted for example in Fig. 7 and Fig. 8, display tiles 500 (each including substrate 510 with light sources (not shown) provided on first surface 512 and drive circuitry or control electronics (not shown) provided on second surface 514, with projections or pins 516, 518 extended from second surface 514) are arrayed in a 1 :1 ratio or relationship with a respective support structure 200, including, more specifically, a 1 :1 ratio or relationship with a respective foundational tile 210 of a respective support structure 200 such that one display tile 500 is supported by one support structure 200. In other examples, multiple display tiles 500 may be supported by and arrayed upon a single support structure 200, including, more specifically, a single foundational tile 210 of a single support structure 200. For example, as depicted in the example of Figs. 9A, 9B, four display tiles 500 (each including substrate 510 with light sources (not shown) provided on first surface 512 and drive circuitry or control electronics (not shown) provided on second surface 514, with projections or pins 516, 518 extended from second surface 514) are supported by and arrayed upon a single support structure 200 including, more specifically, a single foundational tile 210 of a single support structure 200, resulting in a 4:1 ratio or relationship. As such, in the depicted example, projections or pins 516, 518 of respective display tiles 500 extend into
respective holes 206 and slots 208 of foundational tile 210. Although depicted as including four display tiles 500 arranged in an array, in other examples, other numbers of display tiles 500 may be arranged in an array.
Fig. 10 schematically depicts a plan view of an example of a plurality of support structures 600 arranged in an array. For example, four support structures 600, each including a foundational tile 610, standoffs (not shown), similar to standoffs 220 of support structures 200 (Fig. 2A), flanges (not shown), similar to flanges 230 of support structures 200 (Fig. 2A), and magnetic elements (not shown), similar to magnetic elements 240 of support structures 200 (Fig. 2A), are arranged in a 2x2 array. In addition, support structures 600 include respective holes 606 and slots 608, similar to holes 206 and slots 208 of support structures 200.
In the depicted example, foundational tiles 610 of support structures 600 include rounded or radiused corners. As such, the rounded or radiused corners of foundational tiles 610 help to reduce potential interference between corners of foundational tiles 610 due to slight variation in sizing of foundational tiles 610 (e.g., undersized or oversized) when support structures 600 are arrayed.
Although specific examples have been illustrated and described herein, a variety of alternate and/or equivalent implementations may be substituted for the specific examples shown and described without departing from the scope of the present disclosure. This application is intended to cover any adaptations or variations of the specific examples discussed herein
