- Such capturing of the spring 198 on the slide pin 190 maintains outwardly directed force upon the slide pin 190 to attempt to maintain the slide pin 190 in the “engaged” position; i.e., the position utilized for engaged capture of a connector plate such as connector plate 92 .
- a greater portion of the actuator shaft 192 extending from the slide pin 190 is positionally located between the inwardly located panel 200 and the outwardly located panel 206 , and the slide pin 190 is forcibly urged to maintain the “engaged” position by action of the spring 198 .
- Such positioning is accomplished by ensuring that the actuator shaft 192 has been maneuvered through the access slot 204 which intersects the arcuate surface 202 to a position inward of the inwardly located panel 200 and then toggling the actuator shaft 192 either upwardly or downwardly and then releasing the knob 194 to allow the action of the compressed spring 198 to force the actuator shaft 192 to contact the inwardly located panel 200 to cause the slide pin 190 to remain “disengaged” as positioned.
- Positioning of the front spring-loaded slide pin 190 to the closed or “engaged” position is readily and easily accomplished by reorienting the actuator shaft 192 to realign with the access slot 204 to allow the force of the compressed spring 198 to forcibly urge the tapered end of the slide pin 190 fully through the front connector plate receptor slot 130 and the front connector plate receptor 100 , as well as through an engagement hole 92 a of the connector plate 92 for suitable capture thereto.

- a vertically oriented second intermediate panel 238 being part of the rear connector plate receptor 108 and having a hole 240 extending therethrough, and a vertically oriented outwardly located panel 242 being part of the rear connector plate receptor 108 and having an outboard hole 244 extending therethrough are incorporated for support of the slide pin 216 .
- the arcuate surfaces 228 a and 228 b and the holes 236 and 240 always provide support for the slide pin 216 when the slide pin 216 is retracted from the rear connector plate receptor slot 134 .
- the outboard hole 244 also supplies full support for the tapered end of the slide pin 216 when the tapered end of slide pin 216 is positioned just beyond the rear connector plate receptor slot 134 .
- One end of the spring 224 is contained on the slide pin 216 by the pin 222 and the other end of the spring 224 is contained on the slide pin 216 by impingement with the portion of the first intermediate panel 234 surrounding the hole 236 .
- Such capturing of the spring 224 on the slide pin 216 maintains outwardly directed force upon the slide pin 216 to attempt to maintain the slide pin 216 in the “engaged” position; i.e., the position utilized for engagement of a connector plate such as connector plate 94 .
- a greater portion of the actuator shaft 218 extending from the slide pin 216 is positionally located between the inwardly located panel 226 and the first intermediate panel 234 , and the slide pin 216 is forcibly urged to maintain the “engaged” position by action of the spring 224 .
- Such positioning is accomplished by ensuring that the actuator shaft 218 has been maneuvered through either front or rear access slots 230 or 232 which intersect the arcuate surfaces 228 a and 228 b to a position inward of the inwardly located panel 226 and then toggling the actuator shaft 218 either upwardly or downwardly and then releasing the knob 194 to allow the action of the compressed spring 224 to force the actuator shaft 218 to contact the inwardly located panel 226 to cause the slide pin 216 to remain “disengaged” as positioned.
- Positioning of the rear spring-loaded slide pin assembly 140 to the closed or “engaged” position is readily and easily accomplished by reorienting the actuator shaft 218 to realign with either of the front or rear access slots 230 or 232 to allow the force of the compressed spring 224 to forcibly urge the tapered end of slide pin 216 fully through the outwardly located hole 244 and the rear connector plate receptor 108 and through an engagement hole 94 a of the connector plate 94 for suitable capture thereto by incorporating the “engaged” position of the slide pin 216 .

- 2. Description of the Prior Art
- Prior art electronic sign displays can be of gigantic proportion and are fashioned utilizing large and heavy structure which requires heavy handling and positioning devices for installation. Ordinarily, the use of such equipment is not a concern where such electronic sign displays are installed on a one-time permanent basis in a concert hall, auditorium or at a stage setting. Entertainment venues of many sizes and varieties often require electronic sign displays in cooperation with entertainers, rock and roll performances, keynote speakers, bands, orchestras and the like where installation of such electronic sign displays is expensive and often cumbersome. Often the size or shape of electronic sign displays is another factor in that sometimes electronic sign displays are incompatible with doorways, halls and other structural and available space aspects of smaller or older entertainment venues. What is needed is an electronic sign display system which can be handled and simply erected by one person and which is of a suitable size and weight where accommodation and installation of the electronic sign display system in almost any size entertainment area, especially those having difficult access, is readily accomplished. Such a display system is provided by the present invention.
- The general purpose of the present invention is to provide a modular display system including stackable electronic display panels and mounting structure which is easily transported and erected. The modular display system, the present invention, includes a plurality of stackable electronic display panels each removably attached with one or more adjacent stackable electronic display panels to form a display.

With reference toFIGS. 5, 6 and 7, singularly or in combination, or with reference to other figures, other components and features of the invention are now further described. - Aligned attachment of
multiple connector frameworks 14 of the stackableelectronic display panels 2 a-2 n along the vertical aspect is accomplished by the use of components located at or near the intersections of theside panels bottom channels side panels plate mounting slot 122 and a vertically oriented back connectorplate mounting slot 124 are located at the upper end of theside panel 72, and a vertically oriented front connectorplate mounting slot 126 and a vertically oriented back connectorplate mounting slot 128 are located at the upper end of theside panel 74, each mounting slot having suitably located sets of threaded holes extending therethrough for securing of theconnector plates connector plates side panel 72, the frontconnector plate receptor 100 includes a vertically oriented front connectorplate receptor slot 130, and at the lower region of theside panel 74, the frontconnector plate receptor 102 includes a vertically oriented front connectorplate receptor slot 132. Attached to the lower region of theside panel 72 is theconnector assembly 104 having multiple structures including the rearconnector plate receptor 108 which has a vertically oriented rear connectorplate receptor slot 134. Attached to the lower region of theside panel 74 is theconnector assembly 106 having multiple structures including the rearconnector plate receptor 110 which has a vertically oriented rear connectorplate receptor slot 136. A front spring-loadedslide pin assembly 138 is located in and aligns in structure at one end of thebottom channel 78 in suitable alignment with the frontconnector plate receptor 100 and front connectorplate receptor slot 130, and a rear spring-loadedslide pin assembly 140 is located in theslide pin housing 112 in suitable alignment with the rearconnector plate receptor 108 and rear connectorplate receptor slot 134. Correspondingly, a front spring-loadedslide pin assembly 142 is located in and aligns in structure at the other end of thebottom channel 78, generally in suitable alignment with the frontconnector plate receptor 102 and front connectorplate receptor slot 132, as partially shown, and a rear spring-loadedslide pin assembly 144 is located in theslide pin housing 114 in suitable alignment with the rearconnector plate receptor 110 and rear connectorplate receptor slot 136. Connection of theconnector assemblies side panels connector framework 14 and attached components forwardly or rearwardly about the “X” axis.Side latch assemblies segmented compartments 150 and 152 (FIG. 7 ), respectively, in theside panel 72, and sidelatch keeper assemblies segmented compartments 158 and 160 (FIGS. 5 and 6 ), respectively, in theside panel 74 to connect horizontally situatedconnector frameworks 14 and to offer positioning of theconnector frameworks 14 and attached components vertically along the “Y” axis, as later described in detail. Also located in and secured within the geometrically configured structure of theside panel 72 are spring-loadedball detents FIG. 7 ) which assist in initial alignment of theside panel 72 of oneconnector framework 14 to detentholes FIG. 5 ) of theside panel 74 of an adjacently locatedconnector framework 14. With respect to vertically situatedconnector frameworks 14, spring-loadedball detents top channel 76 which assist in initial alignment of thetop channel 76 of aconnector framework 14 to detent holes (not shown) of thebottom channel 78 of anotherconnector framework 14 located thereabove. Threadedholes side panel 72 and threadedholes side panel 74 for mounting of the stackableelectronic display panels 2 a-2 n to a mounting surface, as desired. -
FIGS. 8 and 9 are exploded left and right isometric views showing the junction of theside panel 72 and thebottom channel 78 of aconnector framework 14 and the relationship of components attached to and utilized therewith. The structure and method of attachment of theconnector assembly 104 allows for adjustable attachment to the lower region of theside panel 72 using tongue and groove style geometry coupled with adjustable hardware to facilitate pivotal alignmental actuation of theconnector framework 14 and associated components about the “X” axis. One lower portion of theside panel 72 includes a horizontally orientedtongue 168 which aligns to and which is adjustably actuated vertically within a horizontally orientedgroove 170 at the top of theconnector assembly 104. Mutual fixation of and actuation of theside panel 72 with respect to theconnector assembly 104 is facilitated by the use of a threadedshaft 172, athumbwheel adjuster 174, and other hardware and features. The threadedshaft 172 extends through ahole 176 in an extended portion of the lower region of theside panel 72 and through a portion of thetongue 168, and is affixed therein by anut 178, preferably an acorn nut, at the top of the threadedshaft 172 and anothernut 180 in arecess 182 located in close proximity to thetongue 168. The lower portion of the threadedshaft 172 extends through and below the general structure of thetongue 168 to pass through a series of vertically aligned body holes 184 located below thegroove 170, through a threadedhole 186 at the center of thethumbwheel adjuster 174, and finally into the bottommost of the series of vertically aligned body holes 184 being located in theconnector assembly 104 at a position just below thethumbwheel adjuster 174. An interruptedslot 188 in horizontal orientation in theconnector assembly 104 provides for locating of and rotational access to thethumbwheel adjuster 174 and also provides opposed upper and lower bearing surfaces for intimate adjustmental contact with the upper and lower surfaces of thethumbwheel adjuster 174. Thethumbwheel adjuster 174, which is shown in place inFIG. 7 , includes spacedholes 189 about the periphery for accommodation of an adjustment tool. The interaction of thethumbwheel adjuster 174 and threadedshaft 172 with the interruptedslot 188 provides for screw jack actuation of theconnector assembly 104 with respect to theside panel 72, whereby thetongue 168 is actuated vertically with respect to thegroove 170. More specifically, the interaction of thethumbwheel adjuster 174 and threadedshaft 172 provides for screw jack actuation of theconnector assembly 104 with respect to theside panel 72 about portions of the front spring-loadedslide pin assembly 138. Correspondingly, another threadedshaft 172, anothernut 178, anothernut 180, and anotherthumbwheel adjuster 174 are provided and similarly utilized at the lower portion of theside panel 74. - The front spring-loaded
slide pin assembly 138 includes aslide pin 190 having a taper at one end, anactuator shaft 192 secured to and extending from theslide pin 190, aknob 194 at the outboard end of theactuator shaft 192, apin 196 extending through and beyond the circumference at opposing locations of theslide pin 190, and aspring 198 located about theslide pin 190 and contained thereupon by thepin 196 and structure described later in detail. - Correspondingly as shown in
FIG. 5 , the front spring-loadedslide pin assembly 142 includes aslide pin 190 a having a taper at one end, anactuator shaft 192 a secured to and extending from theslide pin 190 a, aknob 194 a at the outboard end of theactuator shaft 192 a, apin 196 a extending through and beyond the circumference at opposing locations of theslide pin 190 a, and aspring 198 a located about theslide pin 190 a and contained thereupon by thepin 196 a and structure described later in detail. - Structure in the
bottom channel 78 and structure in the frontconnector plate receptor 100 functions as a mount and for interaction with the front spring-loadedslide pin assembly 138 which is positionable therein to a closed or “engaged” position to lockingly and connectingly engage a connector plate, such asconnector plate 92, of one of a vertically situated stackableelectronic display panel 2 a-2 n located below. Such structure includes a vertically aligned inwardly locatedpanel 200 vertically spanning the interior of thebottom channel 78 having anarcuate surface 202 exceeding 180° for accommodation of theslide pin 190, and anaccess slot 204 intersecting thearcuate surface 202. Another structure is a vertically aligned outwardly locatedpanel 206 vertically spanning the interior of thebottom channel 78 having anarcuate surface 208 and intersectingslot 210, whereby the outwardly locatedpanel 206 is incorporated for intimate contact with the inboard end of thespring 198 and whereby thearcuate surface 208 and theslot 210 accommodate theslide pin 190. Other structure includes aninboard hole 212 extending through the inwardly located portion of the front connector plate receptor 100 (FIG. 8 ) and anoutboard hole 214 extending through the outwardly located portion of the front connector plate receptor 100 (FIG. 9 ). Thearcuate surface 202 and theinboard hole 212 always provide support for theslide pin 190 when the tapered end of theslide pin 190 is retracted from the front connectorplate receptor slot 130 toward the open or “disengaged” position. Theoutboard hole 214 supplies full support for the tapered end of theslide pin 190 when the tapered end of theslide pin 190 is positioned just beyond the front connectorplate receptor slot 130 in the “engaged” position. One end of thespring 198 is contained on theslide pin 190 by thepin 196 and the other end of thespring 198 is contained on theslide pin 190 by impingement with the portion of the outwardly locatedpanel 206 surrounding thearcuate surface 208. Such capturing of thespring 198 on theslide pin 190 maintains outwardly directed force upon theslide pin 190 to attempt to maintain theslide pin 190 in the “engaged” position; i.e., the position utilized for engaged capture of a connector plate such asconnector plate 92. During such an “engaged” position, a greater portion of theactuator shaft 192 extending from theslide pin 190 is positionally located between the inwardly locatedpanel 200 and the outwardly locatedpanel 206, and theslide pin 190 is forcibly urged to maintain the “engaged” position by action of thespring 198. Provision is made for positioning and maintaining the front spring-loadedslide pin assembly 138 to the open or “disengaged” position so that unencumbered capture of a connector plate such asconnector plate 92 can be easily and readily accomplished without interference. Such positioning is accomplished by ensuring that theactuator shaft 192 has been maneuvered through theaccess slot 204 which intersects thearcuate surface 202 to a position inward of the inwardly locatedpanel 200 and then toggling theactuator shaft 192 either upwardly or downwardly and then releasing theknob 194 to allow the action of thecompressed spring 198 to force theactuator shaft 192 to contact the inwardly locatedpanel 200 to cause theslide pin 190 to remain “disengaged” as positioned. Positioning of the front spring-loadedslide pin 190 to the closed or “engaged” position is readily and easily accomplished by reorienting theactuator shaft 192 to realign with theaccess slot 204 to allow the force of thecompressed spring 198 to forcibly urge the tapered end of theslide pin 190 fully through the front connectorplate receptor slot 130 and the frontconnector plate receptor 100, as well as through anengagement hole 92 a of theconnector plate 92 for suitable capture thereto. The front spring-loadedslide pin assembly 142 functions in a similar and corresponding manner. - The rear spring-loaded
slide pin assembly 140 is constructed and functions much in the same manner as the front spring-loadedslide pin assembly 138. The rear spring-loadedslide pin assembly 140 includes aslide pin 216 having a taper at one end, anactuator shaft 218 secured to and extending from theslide pin 216, aknob 220 at the outboard end of theactuator shaft 218, apin 222 extending through and beyond the circumference at opposing locations of theslide pin 216, and aspring 224 located about theslide pin 216 and contained thereupon by thepin 222 and structure described later in detail. - The rear spring-loaded
slide pin assembly 144 shown inFIG. 5 includes aslide pin 216 a having a taper at one end, anactuator shaft 218 a secured to and extending from theslide pin 216 a, aknob 220 a at the outboard end of theactuator shaft 218 a, apin 222 a extending through and beyond the circumference at opposing locations of theslide pin 216 a, and aspring 224 a located about theslide pin 216 a and contained thereupon by thepin 222 a and structure described later in detail. The rear spring-loadedslide pin assembly 140 and the rear spring-loadedslide pin assembly 144 function in a similar and corresponding manner. - The
slide pin housing 112 includes a vertically oriented inwardly locatedpanel 226 having opposed upper and lowerarcuate surfaces front access slot 230 and arear access slot 232, each intersecting the opposedarcuate surfaces intermediate panel 234 having ahole 236 extending therethrough. A vertically oriented secondintermediate panel 238 being part of the rearconnector plate receptor 108 and having ahole 240 extending therethrough, and a vertically oriented outwardly locatedpanel 242 being part of the rearconnector plate receptor 108 and having anoutboard hole 244 extending therethrough are incorporated for support of theslide pin 216. - The
arcuate surfaces holes slide pin 216 when theslide pin 216 is retracted from the rear connectorplate receptor slot 134. Theoutboard hole 244 also supplies full support for the tapered end of theslide pin 216 when the tapered end ofslide pin 216 is positioned just beyond the rear connectorplate receptor slot 134. One end of thespring 224 is contained on theslide pin 216 by thepin 222 and the other end of thespring 224 is contained on theslide pin 216 by impingement with the portion of the firstintermediate panel 234 surrounding thehole 236. Such capturing of thespring 224 on theslide pin 216 maintains outwardly directed force upon theslide pin 216 to attempt to maintain theslide pin 216 in the “engaged” position; i.e., the position utilized for engagement of a connector plate such asconnector plate 94. During such an “engaged” position, a greater portion of theactuator shaft 218 extending from theslide pin 216 is positionally located between the inwardly locatedpanel 226 and the firstintermediate panel 234, and theslide pin 216 is forcibly urged to maintain the “engaged” position by action of thespring 224. Provision is made for positioning and maintaining of the rear spring-loadedslide pin assembly 140 to the open or “disengaged” position so that unencumbered capture of a connector plate, such asconnector plate 94, can be easily and readily accomplished without interference. Such positioning is accomplished by ensuring that theactuator shaft 218 has been maneuvered through either front orrear access slots arcuate surfaces panel 226 and then toggling theactuator shaft 218 either upwardly or downwardly and then releasing theknob 194 to allow the action of thecompressed spring 224 to force theactuator shaft 218 to contact the inwardly locatedpanel 226 to cause theslide pin 216 to remain “disengaged” as positioned. Positioning of the rear spring-loadedslide pin assembly 140 to the closed or “engaged” position is readily and easily accomplished by reorienting theactuator shaft 218 to realign with either of the front orrear access slots compressed spring 224 to forcibly urge the tapered end ofslide pin 216 fully through the outwardly locatedhole 244 and the rearconnector plate receptor 108 and through anengagement hole 94 a of theconnector plate 94 for suitable capture thereto by incorporating the “engaged” position of theslide pin 216. The front spring-loadedslide pin assembly 142, the rear spring-loadedslide pin assembly 144, and theconnector assembly 106 are mirror image-like components of the front spring-loadedslide pin assembly 138, the rear spring-loadedslide pin assembly 140, and theconnector assembly 104 having similarly constructed components in mirror image form having the same function and utilization. -
Side latch assemblies segmented compartments 150 and 152 (FIG. 7 ), respectively, in theside panel 72, and sidelatch keeper assemblies segmented compartments 158 and 160 (FIGS. 5 and 6 ), respectively, in theside panel 74 for mutual connection and interaction to connect horizontally situatedconnector frameworks 14 and associated components and to offer positioning of theconnector frameworks 14 and associated components vertically along the “Y” axis. Theside latch assemblies segmented compartments FIGS. 8 and 9 ,side latch assembly 148 is now described. The lowerside latch assembly 148 includes abracket 246 suitable for mounting within thesegmented compartment 152. An operatingshaft 248 having a rearwardly facingtool receptor 250 extends through the opposedsides bracket 246 for pivotal actuation therein. Alatch 256, preferably having a hook shape, is located between thesides shaft 248 and is positioned by the operatingshaft 248 about the axis of the operatingshaft 248. Additionally, anindicator tab 258 secures to and extends inwardly from the rearwardly located portion of the operatingshaft 248 for viewable accommodation by one of a number ofslots 260 located in theside panel 72.Individual indicator tabs 258 are viewable through theslots 260 whenindividual operating shafts 248 each has been rotated to the position where thelatch 256 engages a cam 280 (FIG. 11 ) of an adjacent sidelatch keeper assembly 154 to thereby verify the locked position of thelatches 256. Each of thesegmented compartments panel 262 for accommodation of the operatingshaft 258, as well as opposedangled guide panels side panel 72. Although theopposed guide panels tool receptor 250 of each of theside latch assemblies segmented compartments FIG. 10 . A plurality ofaccess holes 268 are located extending through theside panel 72 for insertion of a suitable adjustment tool for actuation of theside latch assemblies FIG. 10 shows theside latch assembly 146 aligned in and secured within the angledsegmented compartment 150 in the same fashion that theside latch assembly 148 is aligned in and secured within thesegmented compartment 152. Illustrated in particular is the alignment of thetool receptor 250 in theside latch assembly 146 with theguide panels upper access hole 268. -
FIG. 11 is a perspective view of the sidelatch receptor assembly 154, andFIG. 12 is a side view of the sidelatch keeper assembly 154. The sidelatch keeper assemblies segmented compartments FIG. 6 . The sidelatch receptor assembly 154 includes abracket 270 having opposedsides shaft 276, part of which includes ahexagonal exterior 278 and part of which is thecam 280, extends through ahexagonal hole 282 in theside 272 and abody hole 284 in theside 274 of thebracket 270, respectively, for pivotal actuation therein. A rearwardly facingtool receptor 285 is included at one end of the operatingshaft 276. Aspring clip 286 engages one end of the operatingshaft 276 adjacent to the outwardly located surface of theside 274, and aspring 288 aligns over and about one end of the operatingshaft 276 between theside 274 and anannular shoulder 290 located at one end of thecam 280 to spring load theoperating shaft 276 in a direction outwardly from thebracket 270. Such outwardly directed force causes a portion of thehexagonal exterior 278 of the operatingshaft 276 to lockingly engage thehexagonal hole 282 in theside 272 to maintain the last rotational orientation of thecam 280. Agroove 292 interrupts thehexagonal exterior 278 of the operatingshaft 276 at a location near thehexagonal hole 282 to facilitate rotational adjustment of thecam 280 for interaction with the side latch assembly, such asside latch assembly 146 of one of the adjacent stackableelectronic display panels 2 a-2 n, for vertical positional adjustment along the “Y” axis. Rotational adjustment of thecam 280 is initiated by the use of a suitable adjustment tool, such as a hex-head wrench for example, with thetool receptor 285 to forcibly position the operatingshaft 276 against the force of thespring 288 to disengage thehexagonal exterior 278 of the operatingshaft 276 from intimate contact and influence with thehexagonal hole 282 in theside 272. In such a maneuver, thegroove 292 is positioned within thehexagonal hole 282, thereby permitting adjustable rotation of the operatingshaft 276 and thecam 280 to a new position.

- A. Display Panel Design
- Durable, Lightweight and Water Resistant. Each stackable
electronic display panel 2 a-2 n is designed with lightness, ruggedness and water resistance in mind. The result is an IP-65 rated, strong, resilient, weatherized stackable electronic display panel that weighs only 7 kg (15.40 lb.) and measures approximately a half meter. The combined features make the stackableelectronic display panels 2 a-2 n road-ready and equipped for the quickest possible setup in any environment. - Low Heat and Low Noise. Efficient power structure minimizes heat build-up within the stackable
electronic display panels 2 a-2 n, maximizing internal electronics lifetime. In addition, the ultraefficient electronics use arear heat sink 50 for ventilation thereby creating minimal noise, and making the stackableelectronic display panels 2 a-2 n virtually silent during operation. - Serviceability. The stackable
electronic display panels 2 a-2 n are readily serviceable from either the front or the rear. A hex wrench fits inside from the front or the rear and releases the LED displaymodule latching system 52 that holds a stackable electronic display panel in place to aconnector framework 14. The quick release makes changing out stackableelectronic display panels 2 a-2 n easy and fast. - Design Flexibility. The modular display system gives designers the flexibility to create innovative video displays. The approximately half-meter by half-meter stackable
electronic display panels 2 a-2 n shape into virtually any configuration, whether traditional or artistic. The stackableelectronic display panels 2 a-2 n can use rear support structure in the form of the describedconnector framework 14 or custom structures can be designed and built to support the stackableelectronic display panels 2 a-2 n. - Cast Aluminum Structure. Each
connector framework 14 is a lightweight, durable, cast aluminum structure to provide support for the affixedLED display module 16. Weighing 20 lb. (9.1 kg.) alone or 35 lb. (16.1 kg.) when combined with theLED display module 16, theconnector framework 14 is capable of hanging up to 22 stackable electronic display panels, creatingdisplays 36 feet (11 m.) in height. When mounting from the ground, theconnector framework 14 can support up to 10 panels high using ground stand mounting structure, creating displays up to 16 feet (5 m.) high. - Express Assembly and Superior Seam Control. Each
connector framework 14 includes four slide pins that interlock with the connector plates on theconnector framework 14 below to thereby secure the connector frameworks in place with one another. Adjustable side latch assemblies actively draw the panels together vertically eliminating seams between panels. Thumbwheel adjusters on the rear of eachconnector framework 14 adjust horizontal tolerances and guarantee a tight fit and continuous look. - Mounting Flexibility. In addition to the cast
aluminum connector frameworks 14, a variety of other structure options are available. Large scale panel frames can be used for quicker setup of larger displays and cabinet-style frames can be used for permanent installations. - B. Signal Communications
- Redundant Signal. Redundant signal masks signal failures and maximizes display uptime. The proactive feature ensures against the unexpected, keeping imagery constant and unbroken on a display. The innovative, redundant signal design passes image and diagnostic data from display panel to display panel in two directions. If a signal interruption occurs from one direction, the affected display panels automatically switch to the backup signal and a report of the situation is then given back to the computer controller.
- Signal Connectors and Cables. An industry standard, rugged, quick release signal connector guarantees a watertight bond between stackable electronic display panels. An audible, positive-lock click indicates a connector fits snugly in place, keeping the elements out. If a supplied signal cable becomes damaged, it can be temporarily replaced with a standard network cable available from almost any electronics store. This quick fix solution eliminates waiting on manufacturer-supplied cables to keep the show going.
- Operational Status Indicators. Operational status LEDs on the backside of an LED display module give a quick visual indication of the LED display module's operational status. The signal indicators turn off when the data path to the LED display modules is interrupted, alerting support personnel that further examination is required.
- C. Power Delivery
- Remote Power System. To keep noise away from the display, a remote transportable power delivery system or rack that can be located up to 150 feet (45.7 meters) away from the display is provided. The external remote power delivery system removes the power supplies from the display, resulting in a drastically lighter display panel and reducing heat for extended uniformity.
- Power Connectors. An industry standard, rugged, quick release power connector guarantees a watertight bond between display panels. An audible, positive-lock click indicates a connector fits snugly in place, keeping the elements out.
- Hot-Swappable Power. The transportable power rack can be located up 150 feet (45.7 meters) away from the display and allows power units inside the rack to be hot-swapped for one another, keeping a constant supply of power to the display panels. The power rack contains several power units that distribute the power evenly to the display panels. Should one power unit fail, the remaining units pick up the power load and keep the display running. An indicator alerts support personnel of a failed power unit, allowing them to replace the unit for a new one without shutting off power to the display panels.
- Operational Status Indicators. Operational status LEDs on the backsides of the LED display modules give a quick visual indication of the operational status of the LED display modules. The power indicator illuminates when the LED display module receives power, signaling to support personnel that the LED display module works correctly.
- Various modifications can be made to the present invention without departing from the apparent scope hereof.
