     DETAILED DESCRIPTION 
     The present disclosure relates to a modular photograph display system comprising one or more modular illuminated photograph display assemblies, as described in detail below in connection with  FIGS. 1-13 . 
       FIG. 1  is a perspective view of a modular photograph display assembly in accordance with the present disclosure, indicated generally at  10 . The modular photograph display assembly  10  can include a base  12 , frame  14 , and a hollow post  16  coupling the frame  14  to the base  12  and providing an electrical connection therebetween. 
       FIG. 2  is an exploded view of the frame  14  of the modular photograph display assembly of  10 , illustrating components thereof. Specifically, the frame  14  can include a frame back panel  18 , an illumination panel  20 , a photograph matte  22 , a window  24 , and a frame cover  26 . A photograph  28  can be positioned between the illumination panel  20  and the matte  22 . The illumination panel  20  can be edge-lit or back-lit, and can be secured to the frame back panel  18  with double-sided foam tape, adhesive, or any other suitable securing mechanism. The illumination panel  20  can include a first power conductor  30   a  for providing power thereto and a second power conductor  30   b  for providing power to another illumination panel. For example, the first power conductor  30   a  can include a male connector  32   a  and the second power conductor  30   b  can include a female connector  32   b , such that one or more illumination panels  20  can be daisy-chained together and powered from a single driver (see, e.g., light-emitting diode (LED) driver  80  shown in  FIG. 4 ). Additionally, the illumination panel  20  can be configured to emit light at a plurality of different temperatures and/or colors. For example, the illumination panel can output white light at color temperatures of 3900-4500 K, white light at color temperatures of 5000-5500 K, white light at other temperatures, combinations of red-green-blue (RGB) light throughout the color spectrum, or combinations thereof. It is noted that the illumination panel  20  can be illuminated using any source of illumination suitable for backlighting purposes, including, without limitation, LEDs, incandescent illumination (e.g., one or more incandescent bulbs), fluorescent illumination, electroluminescent (EL) illumination, organic light-emitting diode (OLED) illumination, or any other suitable source of illumination. 
     The photograph  28  can be printed on backlight photo paper, such as KODAK brand Universal Backlit Film, or other photograph media suitable for backlighting. As shown in  FIG. 2 , the photograph  28  can be sandwiched between the illumination panel  20  and the matte  22 . The matte  22  can be sized and shaped to form a border around the photograph  28  and can have a thickness (e.g., 0.031 in) sufficient to prevent the window  24  from directly contacting a printed image on the photograph  28 . The matte  22  can be formed from paper card stock, polyvinyl chloride (PVC) plastic, or other suitable materials. The window  24  can be formed from glass, acrylic, or other suitable light-transmissive materials. For example, the window  24  can be formed from ACRYLITE brand P99 non-glare acrylic material or any suitable equivalent. Accordingly, the photograph  28  can be illuminated by the illumination panel  20 , positioned adjacent thereto, and viewed by an observer through the window  24 . 
     One or more clip assemblies  34   a - f  (together, clip assemblies  34 ) can secure the photograph  28 , the matte  22 , and the window  24  against the frame back panel  18 . For example, as shown in  FIG. 2 , the clip assemblies  34  can be attached to the periphery of the frame back panel  18  and can engage a front face of the window  24 , thereby holding the matte  22  and photograph against the illumination panel  20 . A rear side of frame back panel  18  can also be provided with brackets, or other mechanisms, for securing (e.g., mounting) the display assembly  10  to a wall or other surface. 
       FIG. 3  is an exploded view of a clip assembly  34  of the modular photograph display assembly  10  of the present disclosure, illustrating components thereof in greater detail. Each clip assembly  34  can include a clip  36 , a magnet  38 , and a fastener  40 . As shown, the clip  36  can include a generally cylindrical body  42  with a finger  44  extending from an upper edge  46  thereof. The body  42  can include a recess  48  and an aperture  50  can extend through the body  42  along its rotational axis. The clip can be formed from nylon, plastic, or other suitable materials. The magnet  38  can be generally cylindrical, can be sized to be received within the recess  48  of the clip  36 , can have a height that is greater than the depth of the recess  48 , and can have an aperture  52  extending through its rotational axis. The magnet can be formed from NdFeB, grade N42 material, or any other suitable material. The fastener  40  can include a head  54  and a shank  56  that is sized to extend through the aperture  50  of the clip  36  and the aperture  52  of the magnet  38  and secure the clip assembly  34  to the frame back  18 . The fastener  40  can be a screw, as shown in  FIG. 3 , bolt, pin, rivet, or other suitable fastener. 
     The magnet  38  can also include a recess  58  (e.g., countersink or counterbore) sized to accept the head  54  of the fastener  40 , such that the head  54  does not extend beyond a top face  60  of the magnet when the clip assembly is installed on the frame back  18 . When the frame  14  is assembled, the finger  44  of the clip assembly  34  can be rotated towards the center of the frame  14 , thereby engaging the window  24  and securing the picture  28 , matte  22 , and window  24  therein. Conversely, the finger  44  of the clip assembly  34  can be rotated away from the center of the frame  14 , thereby releasing the window  24 , the matte  22 , and picture  28 . Accordingly, a user can easily remove or replace the photograph  28  by rotating the clip assemblies  34 . 
     Returning to  FIG. 2 , the frame  14  can include a cover  26  having a front face  62  and sidewalls  64   a - d  that depend from the front face  62  and extend over sidewalls  66   a - d  of the frame back  18  when the frame  14  is assembled. The sidewalls  64   a - d  of the cover  26  can include one or more cutouts  68   a  and  68   b  ( 68   c  and  68   d  not shown) that are positioned to correspond with apertures  70   a - d  in the sidewalls  66   a - d  of the frame back  18 . The cutouts  68   a  and  68   b  can also correspond in shape with the cross-section of the post  16 , which can be coupled to the frame back  18  at the locations of the apertures  70   a - d . Accordingly, the frame  14  can be selectively mounted with respect to the base  12  in one or more orientations (e.g., horizontal or vertical), based on the location at which the post  16  is attached to the frame back  18 . For example, with respect to  FIG. 2 , if the post  16  is attached to the frame back  18  at the location of aperture  70   c , the frame  14  can be mounted in a horizontal orientation with respect to the base  12 . Conversely, if the post  16  is attached to the frame back  18  at the location of aperture  70   b , the frame  14  can be mounted in a vertical orientation with respect to the base  12 . As will be understood by those of ordinary skill in the art, the power conductor  30   a  of the illumination panel  20  can be routed through the post  16  and corresponding aperture, and into the base  12  of the modular photograph display assembly for connection to a power supply (see, e.g., LED driver  80  shown in  FIG. 4 ). One or more hole covers  72   a - c  can also be provided. As shown in  FIG. 2 , the hole covers  72   a - c  can be sized and shaped to be received within one or more of the cutouts  68   a - d  in the cover  26  and can be configured to engage the frame back  18  of the frame  26 , thereby occluding one or more of the apertures  70   a - d  from view and providing an aesthetically pleasing exterior appearance of the frame  14 . For example, with respect to  FIG. 2 , if the post  16  is attached to the frame back  18  at the location of aperture  70   c , hole covers  72   a - c  can be attached to the frame back  18  at apertures  70   a ,  70   b , and  70   d  respectively. The hole covers  72   a - c  can be attached to the frame back  18  or the cover  26  by snap-fit engagement, magnets, clips or other mechanisms known to those of ordinary skill in the art. 
     As discussed in connection with  FIG. 3 , the magnet top face  60  can extend beyond the clip edge  46  and the head  54  of the fastener  40  when the clip assembly  34  is assembled and attached to the frame back  18 . Additionally, the clip assemblies  34 , the frame back  18 , and the cover  26  can be configured such that the magnet top face  60  contacts the cover  26  when the cover  26  is positioned over the frame back, as shown in  FIG. 1 . Moreover, the cover  26  can be formed from galvanized steel, or other suitable magnetic materials. Accordingly, when the frame  14  is fully assembled, the top face  60  of the magnet  38  can contact the cover  26 , thereby magnetically securing the cover  26  to the frame back  18 . As such, a user can easily access the photograph  28  by magnetically disengaging the cover  26  from the frame back  18  (e.g., by pulling the cover  26  away therefrom), rotating the clip assemblies  34 , and removing the window  24  and matte  22 . Of course, the photograph  28  can be replaced or repositioned and the frame  14  reassembled by reversing the foregoing steps. 
       FIG. 4  is an exploded view illustrating components of the base  12  of the modular photograph display assembly  10  of the present disclosure. The base  12  can include a top panel  74  having an aperture  86 , a base plate  76 , and sidewalls  78   a  and  78   b  forming an enclosure containing electrical components for providing power to, and for controlling, the illumination panel  20 . One or more feet  84   a - d  can be provided on an underside of the base plate  76 . One or more fasteners  88   a  and  88   b  can be provide and configured to attach the post  16  to the base  12  about the aperture  86  in the top panel  74 . The base  12  can enclose an LED driver  80  for providing power to the illumination panel  20  and a controller  82  for modulating the output (e.g., intensity, temperature, color, etc.) of the illumination panel  20 . According to one example, the controller  82  can be electrically coupled to the output of the LED driver  80  and the controller  82  can be electrically coupled to the illumination panel  20  by way of power conductor  30   a . As will be understood by those of ordinary skill in the art, the power conductor  30   a  can be sized to extend from the illumination panel  20 , through one of the aperture  70 - d  in the frame back  18 , through the hollow post  16 , through the aperture  86  in the top panel  74 , and into the base  12  for connection to the controller  82  and/or LED driver  80 . 
       FIG. 5  is a perspective view of the LED driver  80  of the modular photograph display assembly  10 , illustrating connections thereto. The LED driver  80  can include an input power conductor  90  and an output power conductor  92 . The input power conductor  90  can provide power to the LED driver  80  from a power supply (e.g., wall outlet) and can include a switch (e.g., rocker switch or the like) for interrupting power to the LED driver  80  and displaying the photographs without backlit illumination. The output power conductor  92  can include a connector  94  for removably coupling the LED driver  80  to another component. For example, the connector  94  can be a male-type connector and can be coupled to a power conductor extending from the controller  82  having a female-type power connector (see  FIG. 6 ), or vice versa. 
       FIG. 6  is a perspective view of the LED controller  82  of the modular photograph display assembly  10 , illustrating connections thereto. The LED controller  82  can include an input power conductor  96  and an output power/control cable  98 . The input power conductor  96  can include a connector  100  (e.g., male-type or female-type) which can be removably coupled to the connector  94  of the LED driver  80  to provide power to the LED controller  82 . The output power/control cable  98  can include a connector  102  (e.g., male-type or female-type) for removably coupling the LED controller  82  to one or more illumination panels  20 . For example, the female-type connector  102  shown in  FIG. 6  can be coupled to the male-type connector  32   a  of the illumination panel  20 , thereby enabling control of the illumination panel  20  via the LED controller  82 . According to some aspects of the present disclosure, the controller  82  can be provided with wireless communication systems (e.g., RF, Wi-Fi, Bluetooth, etc.) for receiving control commends from a wireless assembly. For example, as shown in  FIG. 6 , the modular photograph display assembly  10  of the present disclosure can be provided with a RF remote  104  for controlling operation of the illumination panel  20  via controller  82 , which can be equipped with an RF receiver. Alternatively, control commands can be sent to the controller  82  from a user&#39;s mobile device (e.g., smartphone, tablet, laptop, etc.) via Wi-Fi communication protocols or via Bluetooth communication protocols. 
       FIG. 7  is a front view of the modular photograph display assembly of the present disclosure, indicated generally at  210 , wherein a plurality of bases  212   a - e  (together, bases  212 ), a plurality of frames  214   a - q  (together, frames  214 ), and a plurality of posts  216   a - q  (together, posts  216 ) are combined to form an array of display assemblies. Each of the bases  212 , frames  214 , and posts  216  can be substantially similar in form and/or function to the base  12 , frame  14 , and post  16  described in connection with  FIGS. 1-4 , except for distinctions noted herein. As shown in  FIG. 7 , a plurality of frames  214  and posts  216  can be arranged in a column on a single base  212  and a plurality of bases  212  can be coupled together to form the modular photograph display assembly  210  of the present disclosure. For example, frames  214   a - c  and posts  216   a - c  can be arranged on base  212   a  in a first column, indicated generally at  220   a , frames  214   d - f  and posts  216   d - f  can be arranged on base  212   b  in a second column, indicated generally at  220   b , frames  214   g - i  and posts  216   g - i  can be arranged on base  212   c  in a third column, indicated generally at  220   c , frames  214   j - 1  and posts  216   j - 1  can be arranged on base  212   d  in a fourth column, indicated generally at  220   d , and frames  214   m - o  and posts  216   m - o  can be arranged on base  212   e  in a fifth column, indicated generally at  220   e . Additionally, an LED driver and/or control unit can be positioned in each of the bases  212  for powering the illumination panels of the frames  214  (e.g., by daisy-chaining) thereabove. Alternatively, a single LED driver and/or control unit can be disposed in one of the bases  212  for powering the illumination panels of the frames  214  in a plurality of columns and/or rows. According to some aspects of the present disclosure, one or more frames  214  can also be coupled to, and extend from, the sides of other frames  214 . For example, as shown in  FIG. 7 , an additional frame  214   q  can be coupled to a right side of frame  214   k  by way of an additional post  216   q  extending horizontally therefrom and a second additional frame  214   p  can be coupled to a left side of frame  214   k  by way of second additional post  216   p  extending horizontally therefrom. The additional horizontally arranged posts  216   p  and  216   q  and frames  214   p  and  214   q  can be coupled to the vertically arranged posts  216  and frames  214  shown in  FIG. 7  using the connections described herein (e.g., the posts being coupled about apertures in the sidewalls of the frame back plates and the illumination panels being daisy-chained together). 
     As shown in  FIG. 7 , the frames  214  can be provided in a plurality of sizes, shapes, and orientations, and configured to accept photographs of various sizes (e.g., 4″×4″, 4″×6″, 4″×8″, 4″×12″, 6″×6″, 6″×9″, 6″×12″, 6″×18″, and the like). As will be appreciated by those of ordinary skill in the art, the assembly  210  is but a single exemplary configuration and a plurality of custom configurations are possible by varying the number of frames  214  in each column, varying the orientation of the frames  214  in each column, and/or varying the number of columns  220 . For example, with respect to  FIG. 7 , the assembly  210  can be reconfigured by removing the frame  214   a  from the first column  220   a , changing the orientation of the frame  214   d  (e.g., from a horizontal to a vertical orientation) in the second column, removing the frame  214   m  from the fifth column  220   e  and adding the frame  214   m  to the third column  220   c , and the like. As shown in  FIG. 7 , when constructing, reconfiguring, and/or adding to the assembly  210  it can be beneficial to position the widest frame  214  in a column at the bottom thereof, in order to maintain stability and structural integrity. Moreover, the base  212  for a particular column  220  can be sized to accommodate the widest frame  214  thereabove. For example, a base  214  can have a width (e.g., 4″, 6″, 8″, 9″, 12″, 18″, etc.) that is greater than or equal to the width of the widest frame  214  in the column  220 . 
     According to some aspects of the present disclosure, the posts  216  (and the posts  16 ) can be provided in a plurality of sizes in order to vary the vertical spacing between the frames  214  and/or the bases  212 . For example, as shown in  FIG. 7 , the posts  216  can have a height of 2″, such that the assembly  210  can be suitably sized for placement on a table, desk, shelf, or the like. Alternatively, posts  216   c ,  216   f ,  2161 , and  216   o  can have a height of 36″ or more, such that the assembly  210  can be suitably sized for placement on a floor and function as a freestanding floor unit. Additional variations in the sizing of the posts  216  are possible and can be selected based on the environment in which the assembly  210  can be placed. 
       FIG. 8  is an exploded view illustrating connections between components of the modular photograph display assembly  210  shown in  FIG. 7 . During assembly of the assembly  210 , the base  212   a , with frame  214   c  and post  216   c  thereon, can be coupled to the base  212   b , with frame  214   f  and post  216   f  thereon. Each of the bases  212  can include one or more of sidewalls  278   a  and  278   b . As shown, sidewalls  278   a  can include a continuous surface and can be suitable for an exterior end of the assembly  210  and sidewalls  278   b  can include an aperture  286  therethrough and one or more fastening mechanisms  288   a - d  (e.g., nuts and bolts, screws, clips, etc.) for removably securing sidewalls  278   b  together. The apertures  286  can be positioned such that when adjacent bases  212   a  and  212   b  are secured together by fasteners  288   a - d , the apertures  286  are aligned and can form a passage between interior spaces of the bases  212   a  and  212   b . As such, electrical connections can be made therebetween. For example, a power and/or control cable can extend from an LED driver and/or controller within base  212   a , through apertures  286  in sidewalls  278   b , and into base  212   b  for connection to an illumination panel positioned within frame  214   f . Accordingly, one or more illumination panels within one or more frames  214  can be couple to and/or controlled by an LED driver and/or controller in a base of an adjacent column. 
       FIG. 9  is a perspective view of a wiring harness  290  of the modular photograph display assembly  210  of the present disclosure. As shown, the wiring harness  290  can include an input power/control cable  292  with a male-type connector  296 , a first output power/control cable  294   a  with a female-type connector  298   a , and a second output power/control cable  294   b  with a female-type connector  298   b . Power/control cables  292 ,  294   a , and  294   b  can be coupled together by way of a junction  300 . Additionally, output power/control cable  294   b  can be longer than output power/control cable  294   a  for connection to a component (e.g., illumination panel, controller, etc.) in an adjacent column  220 , as described below. The wiring harness  290  can provide power and/or control signals to a plurality of illumination panels in a plurality of different frames  214 . For example, with respect to  FIG. 7 , the input power/control cable  292  can be electrically coupled to an LED driver and/or controller positioned within base  212   a , output control/power cable  294   a  can be electrically coupled to an illumination panel within frame  214   c  (which can in turn be coupled with illumination panels in frames  214   b  and  214   a  via daisy-chaining), and output control/power cable  294   b  can be electrically coupled to an illumination panel within frame  214   f  (which can in turn be coupled with illumination panels in frames  214   e  and  214   d  via daisy-chaining). Furthermore, two or more of the wiring harnesses  290  can be connected to power and/or control components in additional columns  210 . 
     According to some aspects of the present disclosure, the modular photograph display system can be designed using a computer based software design application that could be accessed via a website or executed on a local computer system.  FIGS. 10-13  illustrate exemplary graphic user interfaces that can be generated by the computer based software design application of the present disclosure. More specifically,  FIG. 10  is a first graphic user interface generated by the design application of the present disclosure,  FIG. 11  illustrates a first configuration of a modular photograph display system within the graphic user interface of  FIG. 10 ,  FIG. 12  illustrates a second configuration of the modular photograph display system within the graphic user interface of  FIG. 10 , and  FIG. 13  is a second graphic user interface generated by the design application of the present disclosure Such an application can provide the user with a one or more preconfigured display system layouts or present the user with an option to configure a custom display system layout. For example, the system can present the user with a plurality of available photograph/frame sizes and the user can select one or more frames that can be placed in a first column of the display system. Once the user has made a first frame selection (e.g., the frame adjacent to the base and at the bottom of a column), the system can determine an appropriate size for the base (e.g., having a width generally equal to the first frame selection) and can display frames that can be placed on top of the first frame (e.g., frames having widths less than or equal to the first frame). The system can also can prevent the user from selecting frames that cannot be placed on top of the first frame (e.g., frames having widths greater than the first frame) by hiding said frames from the user. After the user has made one or more frame selections for the first column, the system can generate a graphical user interface element (e.g., a button) that allows the user to move to the next column. The user can then repeat the foregoing steps until the user is satisfied with the design and a custom modular display system with one or more columns and/or rows has been completed. As the user is designing the custom display system, the configuration system can generate a three dimensional or two dimensional model, including one or more views, of the design. Once the user has completed the design, the configuration system can prompt the user to upload one or more digital images to system and can position the uploaded images in the one or more frames of the custom photograph display system. Once the photographs have been uploaded to the configuration system and all selections have been confirmed by the user, the configuration system can then fabricate the display system, as specified by the user, print the photographs uploaded by the user, and place said photographs in the appropriate frames. The complete custom display system can then be assembled and shipped to the user.
