Description
- This application claims the benefit of U.S. Provisional Application No. 61/922,631, filed on Dec. 31. 2013, which application is hereby incorporated herein by reference.
- The present invention relates generally to displays, and, in particular embodiments, to a system and method for a modular multi-panel display.
- Large displays (e.g., billboards), such as those commonly used for advertising in cities and along roads, generally have one or more pictures and/or text that are to be displayed under various light and weather conditions. As technology has advanced and introduced new lighting devices such as the light emitting diode (LED), such advances have been applied to large displays. An LED display is a flat panel display, which uses an array of light-emitting diodes. A large display may be made of a single LED display or a panel of smaller LED panels. LED panels may be conventional panels made using discrete LEDs or surface-mounted device (SMD) panels. Most outdoor screens and some indoor screens are built around discrete LEDs, which are also known as individually mounted LEDs. A cluster of red, green, and blue diodes is driven together to form a full-color pixel, usually square in shape. These pixels are spaced evenly apart and are measured from center to center for absolute pixel resolution. At the time of filing this application, one of the largest LED display in the world is over 500 meters long and is located in Fremont Street, Las Vegas.
- Embodiments of the invention relate to lighting systems and, more particularly, to multi-panel lighting systems for providing interior or exterior displays.
- In one embodiment, a modular multi-panel display comprises a frame comprising a plurality of vertical members and a plurality of coupling mechanisms. A plurality of lighting panels is removably coupled directly to the frame using the coupling mechanisms. Each lighting panel is mechanically coupled to one of the vertical and three other lighting panels by a one of the coupling mechanisms. A controller provides data to the plurality of lighting modules.
- In a one particular embodiment, each lighting panel comprises a housing and a plurality of lighting elements positioned within the housing to form a display surface. Circuitry is positioned within the housing to control the plurality of lighting elements and a power supply is positioned within the housing and coupled to the plurality of lighting elements and the circuitry. An input data connection point is coupled to a data output of an upstream one of the lighting panels and/or an output data connection point is coupled to a data input of a downstream one of the lighting panels. An input power connection point is coupled to a power output of the upstream one of the lighting panels and/or an output power connection point is coupled to a power input of the downstream one of the lighting panels. The housing includes four attachment points by which the lighting panel is coupled to the frame. Each attachment point located in a corner region of the lighting panel.

- Referring to
FIGS. 1A and 1B , one embodiment of amulti-panel display 100 is illustrated. Thedisplay 100 includes adisplay surface 102 that is formed bymultiple lighting panels 104 a-104 t. In the present embodiment, thepanels 104 a-104 t use light emitting diodes (LEDs) for illumination, but it is understood that other light sources may be used in other embodiments. Thepanels 104 a-104 t typically operate together to form a single image, although multiple images may be simultaneously presented by thedisplay 100. In the present example, thepanels 104 a-104 t are individually attached to aframe 106, which enables each panel to be installed or removed from theframe 106 without affecting the other panels. - Each
panel 104 a-104 t is a self-contained unit that couples directly to theframe 106. By “directly,” it is understood that another component or components may be positioned between thepanel 104 a-104 t and theframe 106, but the panel is not placed inside a cabinet that is coupled to theframe 106. For example, an alignment plate (described later but not shown in the present figure) may be coupled to a panel and/or theframe 106 to aid in aligning a panel with other panels. The panel may then be coupled to theframe 106 or the alignment plate, and either coupling approach would be “direct” according to the present disclosure. - Two or
more panels 104 a-104 t can be coupled for power and/or data purposes, with apanel 104 a-104 t receiving power and/or data from a central source or another panel and passing through at least some of the power and/or data to one or more other panels. This further improves the modular aspect of thedisplay 100, as asingle panel 104 a-104 t can be easily connected to thedisplay 100 when being installed and easily disconnected when being removed by decoupling the power and data connections from neighboring panels. - The power and data connections for the
panels 104 a-104 t may be configured using one or more layouts, such as a ring, mesh, star, bus, tree, line, or fully-connected layout, or a combination thereof. In some embodiments theLED panels 104 a-104 t may be in a single network, while in other embodiments theLED panels 104 a-104 t may be divided into multiple networks. Power and data may be distributed using identical or different layouts. For example, power may be distributed in a line layout, while data may use a combination of line and star layouts. - The
frame 106 may be relatively light in weight compared to frames needed to support cabinet mounted LED assemblies. In the present example, theframe 106 includes only a tophorizontal member 108, a bottomhorizontal member 110, a leftvertical member 112, a rightvertical member 114, and intermediatevertical members 116. Power cables and data cables (not shown) for thepanels 104 a-104 t may route around and/or through theframe 106. - Referring to
FIGS. 2A-2C , one embodiment of anLED panel 200 is illustrated that may be used as one of theLED panels 104 a-104 t ofFIGS. 1A and 1B .FIG. 2A illustrates a front view of thepanel 200 with LEDs aligned in a 16×32 configuration.FIG. 2B illustrates a diagram of internal components within thepanel 200.FIG. 2C illustrates one possible configuration of a power supply positioned within thepanel 200 relative to a back plate of thepanel 200. - Referring specifically to
FIG. 2A , in the present example, theLED panel 200 includes asubstrate 202 that forms a front surface of thepanel 200. Thesubstrate 202 in the present embodiment is rectangular in shape, with atop edge 204, abottom edge 206, aright edge 208, and aleft edge 210. Asubstrate surface 212 includes “pixels” 214 that are formed by one ormore LEDs 216 on or within thesubstrate 202. In the present example, eachpixel 214 includes fourLEDs 216 arranged in a pattern (e.g., a square). For example, the fourLEDs 216 that form apixel 214 may include a red LED, a green LED, a blue LED, and one other LED (e.g., a white LED). In some embodiments, the other LED may be a sensor. It is understood that more orfewer LEDs 216 may be used to form asingle pixel 214, and the use of fourLEDs 216 and their relative positioning as a square is for purposes of illustration only. - In some embodiments, the
substrate 202 may form the entire front surface of thepanel 200, with no other part of thepanel 200 being visible from the front when thesubstrate 202 is in place. In other embodiments, a housing 220 (FIG. 2B ) may be partially visible at one or more of the edges of thesubstrate 202. Thesubstrate 202 may form the front surface of thepanel 202, but may not be the outer surface in some embodiments. For example, a transparent or translucent material or coating may overlay thesubstrate 202 and theLEDs 216, thereby being positioned between thesubstrate 202/LEDs 216 and the environment. -
Louvers 218 may be positioned above each row ofpixels 214 to block or minimize light from directly striking theLEDs 216 from certain angles. For example, thelouvers 218 may be configured to extend from thesubstrate 202 to a particular distance and/or at a particular angle needed to completely shade eachpixel 214 when a light source (e.g., the sun) is at a certain position (e.g., ten degrees off vertical). In the present example, thelouvers 208 extend the entire length of thesubstrate 202, but it is understood that other louver configurations may be used. - Referring specifically to
FIG. 2B , one embodiment of thepanel 200 illustrates ahousing 220. Thehousing 220 containscircuitry 222 and apower supply 224. Thecircuitry 222 is coupled to theLEDs 216 and is used to control the LEDs. Thepower supply 224 provides power to theLEDs 216 andcircuitry 222. As will be described later in greater detail with respect to two embodiments of thepanel 200, data and/or power may be received for only thepanel 200 or may be passed on to one or more other panels as well. Accordingly, thecircuitry 222 and/orpower supply 224 may be configured to pass data and/or power to other panels in some embodiments. - In the present example, the
housing 220 is sealed to prevent water from entering the housing. For example, thehousing 220 may be sealed to have an ingress protection (IP) rating such as IP67, which defines a level of protection against both solid particles and liquid. This ensures that thepanel 200 can be mounted in inclement weather situations without being adversely affected. In such embodiments, the cooling is passive as there are no vent openings for air intakes or exhausts. - Referring specifically to
FIG. 2C , one embodiment of thepanel 200 illustrates how thepower supply 224 may be thermally coupled to thehousing 220 via a thermally conductive material 226 (e.g., aluminum). This configuration may be particularly relevant in embodiments where thepanel 200 is sealed and cooling is passive. - Referring to
FIGS. 3A-3I , one embodiment of ahousing 300 is illustrated that may be used with one of theLED panels 104 a-104 t ofFIGS. 1A and 1B . For example, thehousing 300 may be a more specific example of thehousing 220 ofFIG. 2B . InFIGS. 3B-3I , thehousing 300 is shown with an alignment plate, which may be separate from thehousing 300 or formed as part of thehousing 300. In the present example, thehousing 300 may be made of a thermally conductive material (e.g., aluminum) that is relatively light weight and rigid. - As shown in the orthogonal view of
FIG. 3A , thehousing 300 defines acavity 302.Structural cross-members substrate 202 ofFIG. 2A ) (not shown). The cross-members 304 and 306, as well as other areas of thehousing 300, may includesupports 308 against which the substrate can rest when placed into position. As shown, thesupports 308 may include a relatively narrow tip section that can be inserted into a receiving hole in the back of the substrate and then a wider section against which the substrate can rest. - The
housing 300 may also include multiple extensions 310 (e.g., sleeves) that provide screw holes or locations for captive screws that can be used to couple the substrate to thehousing 300.Other extensions 312 may be configured to receive pins or other protrusions from a locking plate and/or fasteners, which will be described later in greater detail. Some or all of theextensions 312 may be accessible only from the rear side of thehousing 300 and so are not shown as openings inFIG. 3A . - As shown in
FIG. 3B , analignment plate 314 may be used with thehousing 300. Thealignment plate 314 aids in aligning multiple panels on theframe 106 to ensure that the resulting display surface has correctly aligned pixels both horizontally and vertically. To accomplish this, thealignment plate 314 includestabs 316 and slots 318 (FIG. 3F ). Eachtab 316 fits into theslot 318 of an adjoining alignment plate (if present) and eachslot 318 receives a tab from an adjoining alignment plate (if present). This provides an interlocking series of alignment plates. As eachalignment plate 314 is coupled to or part of ahousing 300, this results in correctly aligning the panels on theframe 106. - It is understood that, in some embodiments, the
alignment plate 314 may be formed as part of the panel or the alignment functionality provided by thealignment plate 314 may be achieved in other ways. In still other embodiments, asingle alignment panel 314 may be formed to receive multiple panels, rather than a single panel as shown inFIG. 3B . - As shown in
FIG. 3C , thehousing 300 may include beveled or otherwise non-squared edges 320. This shaping of the edges enables panels to be positioned in a curved display without having large gaps appear as would occur if the edges were squared. - Referring to
FIGS. 4A and 4B , one embodiment of apanel 400 is illustrated that may be similar or identical to one of theLED panels 104 a-104 t ofFIGS. 1A and 1B . Thepanel 400 may be based on ahousing 401 that is similar or identical to thehousing 300 ofFIG. 3A .FIG. 4A illustrates a back view of thepanel 400 andFIG. 4B illustrates a top view. Thepanel 400 has a width W and a height H. - In the present example, the back includes a number of connection points that include a “power in”
point 402, a “data in”point 404, a main “data out”point 406, multipleslave data points 408, and a “power out”point 410. The power inpoint 402 enables thepanel 400 to receive power from a power source, which may be another panel. The data inpoint 404 enables the panel to receive data from a data source, which may be another panel. The main data outpoint 406 enables thepanel 400 to send data to another main panel. The multipleslave data points 408, which are bi-directional in this example, enable thepanel 400 to send data to one or more slave panels and to receive data from those slave panels. In some embodiments, the main data outpoint 406 and the slave data outpoints 408 may be combined. The power outpoint 410 enables thepanel 400 to send power to another panel. - The connection points may be provided in various ways. For example, in one embodiment, the connection points may be jacks configured to receive corresponding plugs. In another embodiment, a cable may extend from the back panel with a connector (e.g., a jack or plug) affixed to the external end of the cable to provide an interface for another connector. It is understood that the connection points may be positioned and organized in many different ways.
- Inside the panel, the power in
point 402 and power outpoint 410 may be coupled to circuitry (not shown) as well as to a power supply. For example, the power inpoint 402 and power outpoint 410 may be coupled to thecircuitry 222 ofFIG. 2B , as well as to thepower supply 224. In such embodiments, thecircuitry 222 may aid in regulating the reception and transmission of power. In other embodiments, the power inpoint 402 and power outpoint 410 may by coupled only to thepower supply 224 with a pass through power connection allowing some of the received power to be passed from the power inpoint 402 to the power outpoint 410. - The data in
point 404, main data outpoint 406, and slave data outpanels 408 may be coupled to thecircuitry 222. Thecircuitry 222 may aid in regulating the reception and transmission of the data. In some embodiments, thecircuitry 222 may identify data used for thepanel 400 and also send all data on to other coupled main and slave panels via the main data outpoint 406 and slave data outpoints 408, respectively. In such embodiments, the other main and slave panels would then identify the information relevant to that particular panel from the data. In other embodiments, thecircuitry 222 may remove the data needed for thepanel 400 and selectively send data on to other coupled main and slave panels via the main data outpoint 406 and slave data outpoints 408, respectively. For example, thecircuitry 222 may send only data corresponding to a particular slave panel to that slave panel rather than sending all data and letting the slave panel identify the corresponding data. - The back panel also has
coupling points housing 300 ofFIG. 3A , the coupling points 412 and 414 may correspond toextensions - Referring specifically to
FIG. 4B , a top view of thepanel 400 illustrates three sections of thehousing 401. Thefirst section 416 includes the LEDs (not shown) andlouvers 418. Thesecond section 420 andthird section 422 may be used to house thecircuitry 222 andpower supply 224. In the present example, thethird section 422 is an extended section that may exist on main panels, but not slave panels, due to extra components needed by a main panel to distribute data. Depths D1, D2, and D3 correspond tosections - Referring to
FIG. 5 , one embodiment of apanel 500 is illustrated that may be similar or identical to thepanel 400 ofFIG. 4A with the exception of a change in the slave data points 408. In the embodiment ofFIG. 4A , theslave data points 408 are bi-directional connection points. In the present embodiment, separate slave “data in”points 502 and slave “data out” points 504 are provided. - Referring to
FIGS. 6A and 6B , one embodiment of apanel 600 is illustrated that may be similar or identical to thepanel 400 ofFIG. 4A except that thepanel 600 is a slave panel.FIG. 6A illustrates a back view of thepanel 600 andFIG. 6B illustrates a top view. Thepanel 400 has a width W and a height H. In the present embodiment, these are identical to the width W and height H of thepanel 400 ofFIG. 4A . In contrast to the main panel ofFIG. 4A , the back of theslave panel 600 has a more limited number of connection points that include a “power in”point 602, adata point 604, and a “power out”point 606. The power inpoint 602 enables thepanel 600 to receive power from a power source, which may be another panel. Thedata point 604 enables the panel to receive data from a data source, which may be another panel. The power outpoint 606 enables thepanel 600 to send power to another main panel. In the present example, thedata point 604 is bi-directional, which corresponds to the main panel configuration illustrated inFIG. 4A . The back panel also hascoupling points coupling points FIG. 4A . - Referring specifically to
FIG. 6B , a top view of thepanel 600 illustrates two sections of thehousing 601. Thefirst section 612 includes the LEDs (not shown) andlouvers 614. Thesecond section 616 may be used to house thecircuitry 222 andpower supply 224. In the present example, the extended section provided by thethird section 422 ofFIG. 4A is not needed as thepanel 600 does not pass data on to other panels. Depths D1 and D2 correspond tosections panel 400 ofFIG. 4B . - It is noted that the similarity in size of the
panels 400 ofFIG. 4A and thepanel 600 ofFIG. 6A enables the panels to be interchanged as needed. More specifically, as main panels and slave panels have an identical footprint in terms of height H, width W, and depth D1, their position on theframe 106 ofFIGS. 1A and 1B does not matter from a size standpoint, but only from a functionality standpoint. Accordingly, thedisplay 100 can be designed as desired using main panels and slave panels without the need to be concerned with how a particular panel will physically fit into a position on the frame. The design may then focus on issues such as the required functionality (e.g., whether a main panel is needed or a slave panel is sufficient) for a particular position and/or other issues such as weight and cost. - In some embodiments, the
main panel 400 ofFIG. 4A may weigh more than theslave panel 600 due to the additional components present in themain panel 400. The additional components may also make themain panel 400 more expensive to produce than theslave panel 600. Therefore, a display that uses as many slave panels as possible while still meeting required criteria will generally cost less and weigh less than a display that uses more main panels. - Referring to
FIG. 7 , one embodiment of apanel 700 is illustrated that may be similar or identical to thepanel 600 ofFIG. 6A with the exception of a change in thedata point 604. In the embodiment ofFIG. 6A , thedata point 604 is a bi-directional connection. In the present embodiment, a separate “data out”point 702 and a “data in”point 704 are provided, which corresponds to the main panel configuration illustrated inFIG. 5 . - Referring to
FIGS. 8A-8M , embodiments of aframe 800 are illustrated. For example, theframe 800 may provide a more detailed embodiment of theframe 106 ofFIG. 1B . As described previously, LED panels, such as thepanels 104 a-104 t ofFIGS. 1A and 1B , may be mounted directly to theframe 800. Accordingly, theframe 800 does not need to be designed to support heavy cabinets, but need only be able to support thepanels 104 a-104 t and associated cabling (e.g., power and data cables), and theframe 800 may be lighter than conventional frames that have to support cabinet based structures. For purposes of example, various references may be made to thepanel 200 ofFIG. 2A , thehousing 300 ofFIG. 3A , and thepanel 400 ofFIG. 4A . - In the present example, the
frame 800 is designed to supportLED panels 802 in a configuration that is ten panels high and thirty-two panels wide. While the size of thepanels 802 may vary, in the current embodiment this provides a display surface that is approximately fifty feet and four inches wide (50′ 4″) and fifteen feet and eight and three-quarters inches high (15′ 8.75″). - It is understood that all measurements and materials described with respect to
FIGS. 8A-8M are for purposes of example only and are not intended to be limiting. Accordingly, many different lengths, heights, thicknesses, and other dimensional and/or material changes may be made to the embodiments ofFIGS. 8A-8M . - Referring specifically to
FIG. 8B , a back view of theframe 800 is illustrated. Theframe 800 includes atop bar 804, abottom bar 806, aleft bar 808, aright bar 810, and multiplevertical bars 812 that connect thetop bar 804 andbottom bar 806. In some embodiments, additionalhorizontal bars 814 may be present. - The
frame 800 may be constructed of various materials, including metals. For example, thetop bar 804, thebottom bar 806, theleft bar 808, and the right bar 810 (e.g., the perimeter bars) may be made using a four inch aluminum association standard channel capable of bearing 1.738 lb/ft. Thevertical bars 812 may be made using 2″×4″×½″ aluminum tube capable of bearing a load of 3.23 lb/ft. - It is understood that these sizes and load bearing capacities are for purposes of illustration and are not intended to be limiting. However, conventional steel display frames needed to support conventional cabinet-based displays are typically much heavier than the
frame 800, which would likely not be strong enough to support a traditional cabinet-based display. For example, theframe 800 combined with the panels described herein may weigh at least fifty percent less than equivalent steel cabinet-based displays. - Referring to
FIG. 8C , a cutaway view of theframe 800 ofFIG. 8B taken along lines A1-A1 is illustrated. Thehorizontal bars 810 are more clearly visible. More detailed views ofFIG. 8C are described below. - Referring to

A firstflat bar 816 may be used withmultiple fasteners 818 to couple thetop bar 804 to thevertical bar 812 at the back of theframe 800. A secondflat bar 820 may be used withfasteners 821 to couple thetop bar 804 to thevertical bar 812 at the front of theframe 800. Afront plate 902 belonging to a coupling mechanism 900 (described below with respect toFIG. 9A ) is illustrated. The secondflat bar 820 may replace a back plate of thecoupling mechanism 900. In embodiments where the secondflat bar 820 replaces the back plate, the secondflat bar 820 may include one or more holes to provide accessibility to fasteners of thecoupling mechanism 900. - Referring to

clip 822 may be coupled to avertical bar 812 via one ormore fasteners 824 and to thehorizontal bar 814 via one ormore fasteners 824. In the present example, theclip 822 is positioned above thehorizontal bar 814, but it is understood that theclip 822 may be positioned below thehorizontal bar 814 in other embodiments. In still other embodiments, theclip 822 may be placed partially inside the horizontal bar 814 (e.g., a portion of theclip 822 may be placed through a slot or other opening in the horizontal bar 814). - Referring to
FIGS. 8H and 8I , various more detailed views of theframe 800 ofFIG. 8C are illustrated.FIG. 8H provides a more detailed view of theframe 800 ofFIG. 8C at location B3.FIG. 8I provides a cutaway view of theframe 800 ofFIG. 8H taken along lines D1-D1. - The cutaway view shows the
bottom bar 806 and avertical bar 812. A firstflat bar 826 may be used withmultiple fasteners 828 to couple thebottom bar 806 to thevertical bar 812 at the back of theframe 800. A secondflat bar 830 may be used withfasteners 832 to couple thebottom bar 806 to thevertical bar 812 at the front of theframe 800. Afront plate 902 belonging to a coupling mechanism 900 (described below with respect toFIG. 9A ) is illustrated. The secondflat bar 830 may replace a back plate of thecoupling mechanism 900. In embodiments where the secondflat bar 830 replaces the back plate, the secondflat bar 830 may include one or more holes to provide accessibility to fasteners of thecoupling mechanism 900. - Referring to
FIGS. 8J and 8K , various more detailed views of theframe 800 ofFIG. 8A are illustrated.FIG. 8H provides a more detailed view of theframe 800 ofFIG. 8B at location A2.FIG. 8K provides a cutaway view of theframe 800 ofFIG. 8J taken along lines E1-E1. The two views show thebottom bar 806 and theleft bar 808. Aclip 834 may be used withmultiple fasteners 836 to couple thebottom bar 806 to theleft bar 808 at the corner of theframe 800. - Referring to
FIGS. 8L and 8M , an alternative embodiment toFIG. 8E is illustrated.FIG. 8L provides a more detailed view of theframe 800 in the alternate embodiment.FIG. 8M provides a cutaway view of theframe 800 ofFIG. 8L taken along lines F1-F1. In this embodiment, rather than using ahorizontal bar 814, avertical bar 812 is coupled directly to abeam 840 using aclip 838. - Referring to
FIGS. 9A-9C , one embodiment of acoupling mechanism 900 is illustrated that may be used to attach an LED panel (e.g., one of thepanels 104 a-104 t ofFIGS. 1A and 1B ) to a frame (e.g., theframe 106 or theframe 800 ofFIGS. 8A and 8B ). For purposes of example, thecoupling mechanism 900 is described as attaching thepanel 200 ofFIG. 2A to theframe 800 ofFIG. 8B . In the present example, asingle coupling mechanism 900 may attach up to four panels to theframe 800. To accomplish this, thecoupling mechanism 900 is positioned where the corners of four panels meet. - The
coupling mechanism 900 includes afront plate 902 and aback plate 904. Thefront plate 902 has anouter surface 906 that faces the back of a panel and aninner surface 908 that faces theframe 106. Thefront plate 902 may include acenter hole 910 and holes 912. Thecenter hole 910 may be countersunk relative to theouter surface 906 to allow a bolt head to sit at or below theouter surface 906. Mountingpins 914 may extend from theouter surface 906. Theback plate 904 has anouter surface 916 that faces away from theframe 106 and aninner surface 918 that faces theframe 106. Theback plate 904 includes acenter hole 920 and holes 922. - In operation, the
front plate 902 andback plate 904 are mounted on opposite sides of one of thevertical bars front plate 902 mounted on the panel side of theframe 800 and theback plate 904 mounted on the back side of theframe 800. For purposes of example, avertical bar 812 will be used. When mounted in this manner, theinner surface 908 of thefront plate 902 and theinner surface 918 of theback plate 904 face one another. A fastener (e.g., a bolt) may be placed through thecenter hole 910 of thefront plate 902, through a hole in thevertical bar 812 of theframe 800, and through thecenter hole 920 of theback plate 904. This secures thefront plate 902 andback plate 904 to theframe 800 with the mountingpins 914 extending away from the frame. - Using the
housing 300 ofFIG. 3A as an example, a panel is aligned on theframe 800 by inserting theappropriate mounting pin 914 into one of the holes in the back of thehousing 300 provided by anextension 310/312. It is understood that this occurs at each corner of the panel, so that the panel will be aligned with theframe 800 using four mountingpins 914 that correspond to fourdifferent coupling mechanisms 900. It is noted that thepins 914 illustrated inFIG. 9C are horizontally aligned with theholes 912, while the extensions illustrated inFIG. 3A are vertically aligned. As described previously, these are alternate embodiments and it is understood that theholes 912/pins 914 andextensions 310/312 should have a matching orientation and spacing. - Once in position, a fastener is inserted through the
hole 922 of theback plate 904, through thecorresponding hole 912 of thefront plate 902, and into a threaded hole provided by anextension 310/312 in thepanel 300. This secures the panel to theframe 800. It is understood that this occurs at each corner of the panel, so that the panel will be secured to theframe 800 using fourdifferent coupling mechanisms 900. Accordingly, to attach or remove a panel, only four fasteners need be manipulated. Thecoupling mechanism 900 can remain in place to support up to three other panels. - More precise alignment may be provided by using an alignment plate, such as the
alignment plate 314 ofFIG. 3B , with each panel. For example, while positioning the panel and prior to tightening thecoupling mechanism 900, thetabs 316 of thealignment plate 314 for that panel may be inserted intoslots 318 in surrounding alignment plates. Thecoupling mechanism 900 may then be tightened to secure the panel into place. - It is understood that many different configurations may be used for the
coupling mechanism 400. For example, the locations of holes and/or pins may be moved, more or fewer holes and/or pins may be provided, and other modifications may be made. It is further understood that many different coupling mechanisms may be used to attach an panel to theframe 106. Such coupling mechanisms may use bolts, screws, latches, clips, and/or any other fastener suitable for removably attaching a panel to theframe 800. - Referring to
FIGS. 10A and 10B , one embodiment of a 13×22panel display 1000 is illustrated that includes two hundred and eighty-six panels arranged in thirteen rows and twenty-two columns. For purposes of example, thedisplay 1000 uses the previously describedmain panel 400 ofFIG. 4A (a ‘B’ panel) and theslave panel 600 ofFIG. 6A (a ‘C’ panel). As described previously, these panels have a bi-directional input/output connection point for data communications between the main panel and the slave panels. The rows are divided into two sections with the top section having seven rows and the bottom section having six rows. The B panels form the fourth row of each section and the remaining rows are C panels.FIGS. 10C and 10D provide enlarged views of a portion ofFIGS. 10A and 10B , respectively. - As illustrated in
FIG. 10A , power (e.g., 220V single phase) is provided to the top section via seven breakers (e.g., twenty amp breakers), with a breaker assigned to each of the seven rows. Power is provided to the bottom section via six breakers, with a breaker assigned to each of the six rows. In the present example, the power is provided in a serial manner along a row, with power provided to the first column panel via the power source, to the second column panel via the first panel, to the third column panel via the second panel, and so on for the entire row. Accordingly, if a panel is removed or the power for a panel is unplugged, the remainder of the panels in the row will lose power. - As illustrated in
FIG. 10B , data is sent from a data source 1002 (e.g., a computer) to the top section via one line and to the bottom section via another line. In some embodiments, as illustrated, the data lines may be connected to provide a loop. In the present example, the data is provided to the B panels that form the fourth row of each section. The B panels in the fourth row feed the data both vertically along the column and in a serial manner along the row. For example, the B panel at row four, column two (r4:c2), sends data to the C panels in rows one, two, three, five, six, and seven of column two (r1-3:c2 and r5-7:c2), as well as to the B panel at row four, column three (r4:c3). Accordingly, if a B panel in row four is removed or the data cables are unplugged, the remainder of the panels in the column fed by that panel will lose their data connection. The next columns will also lose their data connections unless the loop allows data to reach them in the opposite direction. - It is understood that the data lines may be bi-directional. In some embodiments, an input line and an output line may be provided, rather than a single bi-directional line as illustrated in
FIGS. 10A and 10B . In such embodiments, the panels may be configured with additional input and/or output connections. An example of this is provided below inFIGS. 11A and 11B . - Referring to
FIGS. 11A and 11B , one embodiment of a 16×18panel display 1100 is illustrated that includes two hundred and eighty-eight panels arranged in sixteen rows and eighteen columns. For purposes of example, thedisplay 1100 uses the previously describedmain panel 500 ofFIG. 5 (a ‘B’ panel) and theslave panel 700 ofFIG. 7 (a ‘C’ panel). As described previously, these panels have separate input and outpoint connection points for data communications between the main panel and the slave panels.FIGS. 11C and 11D provide enlarged views of a portion ofFIGS. 11A and 11B , respectively. - As illustrated in
FIG. 11A , power is provided from a power source directly to the first column panel and the tenth column panel of each row via a power line connected to a single 110V, 20 Å breaker. Those panels then feed the power along the rows in a serial manner. For example, the power is provided to the first column panel via the power source, to the second column panel via the first panel, to the third column panel via the second panel, and so on until the ninth column panel is reached for that row. The ninth column panel does not feed power to another panel because power is provided directly to the tenth column panel via the power source. Power is then provided to the eleventh column panel via the tenth panel, to the twelfth column panel via the eleventh panel, and so on until the end of the row is reached. Accordingly, if a panel is removed or the power for a panel is unplugged, the remainder of the panels in the row that rely on that panel for power will lose power. - Although not shown in
FIG. 11B , the panels of thedisplay 1100 may be divided into two sections for data purposes as illustrated previously with respect toFIG. 10B . Accordingly, as illustrated inFIG. 10B , data may be sent from a data source (e.g., a computer) to a top section via one line and to a bottom section via another line. As the present example illustrates the use of separate input and outpoint connection points for data communications between the main panel and the slave panels, data connections between B panels have been omitted for purposes of clarity. - In the present example, the data is provided to the B panels that form the fourth row of each section. The B panels in the fourth row feed the data both vertically along the column and in a serial manner along the row (as shown in
FIG. 10B ). For example, the B panel at row four, column two (r4:c2), sends data to the C panels in rows one, two, three, five, six, seven, and eight of column two (r1-3:c2 and r5-8:c2), as well as to the B panel at row four, column three (r4:c3). Accordingly, if a B panel in row four is removed or the data cables are unplugged, the remainder of the panels in the column fed by that panel will lose their data connection. The next columns will also lose their data connections unless the loop allows data to reach them in the opposite direction. - Referring to
FIGS. 12A and 12B , one embodiment of a 19×10 panel twoface display 1100 is illustrated that includes three hundred and eighty panels arranged in two displays of nineteen rows and ten columns. For purposes of example, thedisplay 1100 uses the previously describedmain panel 500 ofFIG. 5 (a ‘B’ panel) and theslave panel 700 ofFIG. 7 (a ‘C’ panel). As described previously, these panels have separate input and outpoint connection points for data communications between the main panel and the slave panels.FIGS. 12C and 12D provide enlarged views of a portion ofFIGS. 12A and 12B , respectively. - As illustrated in
FIG. 12A , power is provided from a power source directly to the first column panel of each face via a power line connected to a single 110V, 20 Å breaker. Those panels then feed the power along the rows in a serial manner. For example, the power is provided to the first column panel of the first face via the power source, to the second column panel via the first panel, to the third column panel via the second panel, and so on until the last panel is reached for that row of that face. The tenth column panel does not feed power to the next face because power is provided directly to the first column of the second face via the power source. Power is then provided to the second column panel via the first panel, to the third column panel via the second panel, and so on until the last panel is reached for that row of that face. Accordingly, if a panel is removed or the power for a panel is unplugged, the remainder of the panels in the row that rely on that panel for power will lose power. - Although not shown in
FIG. 12B , the panels of thedisplay 1200 may be divided into three sections for data purposes as illustrated previously with respect toFIG. 10B . Accordingly, as illustrated inFIG. 10B , data may be sent from a data source (e.g., a computer) to the top section via one line, to a middle section via a second line, and to a bottom section via a third line. - As the present example illustrates the use of separate input and outpoint connection points for data communications between the main panel and the slave panels, data connections between B panels have been omitted for purposes of clarity. However, a separate line may be run to the B panels in the first column of each face (which would require six lines in
FIG. 12B ), or the B panel in the last column of a row of one face may pass data to the B panel in the first column of a row of the next face (which would require three lines inFIG. 12B ). - In the present example, the data is provided to the B panels that form the fourth row of each section. The B panels in the fourth row feed the data both vertically along the column and in a serial manner along the row (as shown in
FIG. 10B ). For example, the B panel at row four, column two (r4:c2), sends data to the C panels in rows one, two, three, five, and six of column two (r1-3:c2 and r5-6:c2), as well as to the B panel at row four, column three (r4:c3). Accordingly, if a B panel in row four is removed or the data cables are unplugged, the remainder of the panels in the column fed by that panel will lose their data connection. The next columns will also lose their data connections unless the loop allows data to reach them in the opposite direction. - Although the preferred embodiment has been described in detail, it should be understood that various changes, substitutions and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
