     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the claims. 
     The following disclosure relates to video display systems, related systems, components and methods. 
     Video display systems may require large installation footprints in order to accommodate large support structures, audio and video equipment, power, and separate cooling systems required for dissipating the large amount of heat the video display wall creates. The large footprint occupies space otherwise available for other uses, such as retail sales displays. For example, conventional video display systems can extend more than 36 inches in depth. Moreover, different installation locations may include different structural configurations, limiting installation options. 
     Design and form factor are also considerations when implementing video display systems. Providing a pleasing aesthetic for large-scale video display systems can be a challenge, given structural requirements and packaging. 
     Additionally, heat dissipation requirements for such video display systems may use large ducting and diffusers, increasing the overall footprint required for installation. Some systems may utilize a supply air source that is directed from the top of the video screen wall and forces air to flow down. However, due to convection as the airflow travels across the surface of the screen, turbulence is increased and the airflow is directed away from the screen, which can result in decreased cooling efficiency and decreased comfort for individuals proximate the video display system. 
     Those skilled in the art will readily appreciate that the detailed description given herein with respect to the figures is for explanatory purposes only and should not be construed as limiting. 
     As shown in the figures, for example, some embodiments relate to a video display system  10 , including a video display  100  which includes a plurality of video display modules  102  (as shown in  FIG. 3 , for example) and a truss  200  supporting video display  100 . A lower portion  202  of truss  200  may be anchored to a floor  600 . Lower portion  202  may be coupled to video display  100  at a position between the terminal sides  114  of the video display  100  and may extend approximately one-third of the length of video display  100 . In some embodiments, the system may include an upper portion  204  of truss  200  above lower portion  202  and anchored to a ceiling  602 , and second portion  204  may be coupled to video display  100  at a position between terminal sides  114  of video display  100 . Video display  100  may be positioned entirely in front of truss  200  in some embodiments. 
     Some embodiments may include a ceiling reinforcement  610 . Some embodiments may include a wall reinforcement  612 . These reinforcements may be made, for example, of glass-fiber-reinforced concrete. In some embodiments, these reinforcements may be a composite structure, including for example, beams, brackets, concrete reinforcements, and the like. Some embodiments may include a ceiling channel  608 . Ceiling channel  608  may, for example, be used to house portions of electronic components, such as speakers, or provide access for anchoring video display system  10 . 
     As shown in the figures, relative dimensions of embodiments are referred to with reference to video display  100  for ease of description. A length of video display  100  extends with respect to a coordinate  700 , a height of video display  100  extends with respect to a coordinate  702 , a depth of video display  100  extends with respect to coordinate  704 . A portion of video display  100  including screen  116  may be referred to as a front side of video display  100 . 
     Video display  100  may be a large-scale video display. Aspects of the embodiments described herein may help to accommodate the large-scale nature of video display  10 , as will be apparent to one of skill in the art. In some embodiments the height of video display  10  may be between 6 feet and 25 feet, 8 feet and 12 feet, 9 feet and 11 feet, or 10 feet. In some embodiments the length of the video display  10  may be between 10 feet and 25 feet, 14 feet and 21 feet, 16 feet and 19 feet, or 18 feet. In some embodiments the depth of the outer dimension of the video display  10  to rear surface of outer housing  104  may be less than 36 inches, less than 30 inches, less than 20 inches, less than 15 inches, or less than 10 inches. In some embodiments, the depth of the outer dimension of the screen  116  to rear surface of outer housing  104  may be 10 inches. In some embodiments, the perimeter edge of outer housing  104  may be thinner than the maximum depth. In some embodiments the edge thickness in the depth direction of the outer housing  104  may be less than 10 inches, less than 8 inches, less than 6 inches, or less than 4 inches. In some embodiments the edge thickness in the depth direction of the outer housing  104  may be 4 inches. As discussed above, design and form factor are also considerations when implementing video display systems. 
     Providing a pleasing aesthetic and compact form factor for a large-scale video display system can be a challenge. In some embodiments, the proportion of the truss structure and selection of video display system  10 ,  20 ,  30 , or  40 , may be configured in relation to one or more of the video display  100  dimensions, outer housing  114  dimensions, component module housing  108  dimensions, or other environmental dimensions. For example, if the video display  100  is relatively small and the ceiling height is relatively small, the environment may call for the wall mounting of video display system  40 . However, as screen size increases along with ceiling height, video display systems  10 ,  20 , and  30  may be selected. These scalable dimensions convey similar form factors and visual appearances. 
     In some embodiments, the height of component module housing  108  may be between 3 inches and 24 inches, 4 inches and 20 inches, 5 inches and 15 inches, or 6 inches and 10 inches. 
     Referring generally to  FIGS. 1 and 6 , the positioning of truss  200  behind the video display  100  results in the video display  100  being cantilevered forward. In some embodiments, video display  100  may appear cantilevered forward from a surface of component module housing  108  by between 3 inches and 24 inches, 4 inches and 20 inches, 5 inches and 15 inches, 6 inches and 12 inches, or approximately 10 inches. In some embodiments, the front surface of video display  100  is disposed forward of lower or upper portion  202 / 204  of truss  200  by more than approximately 6 inches. In some embodiments, the front surface of video display  100  is disposed forward of lower or upper portion  202 / 204  of truss  200  by more than approximately 6 inches, but less than approximately 36 inches. In some embodiments, the front surface of video display  100  is disposed forward of lower or upper portion  202 / 204  of truss  200  by more than approximately 8 inches, but less than approximately 24 inches. In some embodiments, the front surface of video display  100  is disposed forward of lower or upper portion  202 / 204  of truss  200  by more than approximately 10 inches, but less than approximately 18 inches. In some embodiments, the front surface of video display  100  is disposed forward of lower or upper portion  202 / 204  of truss  200  by approximately 10 inches. 
     In some embodiments, upper portion  204  of truss  200  may be above lower portion  202  and may extend approximately one-third of the length of video display  100 . As used herein, “approximately” may be taken to mean within 10% of the recited value, inclusive. In some embodiments, a component module housing  108  may house portions of truss  200 . In some embodiments, component module housing  108  may appear to be acting as a support for video display  100 . As discussed,  FIGS. 1 and 2 , for example, illustrate the visual effect created with video display wall  100  appearing cantilevered about component module housing  108 . The relative proportions of visible structure, along with their placement is advantageous as it increases the compactness of the overall footprint. Additionally, the relative proportions of visible structure and their placement contributes to a sleek, expansive, unencumbered visual impression, increasing the aesthetics of the system. In some embodiments, component module housing  108  may appear to support video display  100  in a cantilevered fashion.  FIG. 2  additionally illustrates various locations for speakers  106 , for example within component module housing  108 , which may include perforations  110 . Component module housing  108  may also enclose a portion of truss  200 , or other related electronics or mechanical equipment included in video display system  10  or video display  100 , to contribute to the compactness of video display system  10  or video display  100 . 
     As shown in  FIGS. 2 and 4 , a door  606  may be behind video display system  10 , which may lead to a secondary area, such as a stock room, or an access room for maintaining and accessing components of video display system  10 , such as audio or visual components (e.g., “AV”). For example, this area may be a “back of house” area in a retail setting. Since such an area may be behind video display system  10 , the compactness of video display system  10  minimizes impeding on this area, thereby contributing an efficient use of space.  FIG. 3  shows channel  608 , which video display system  10  may be positioned relative to in order to take advantage of structural or architectural features provided in an installation environment. For example, ceiling channel  608  may house speakers  106 , or air ducts, for example. As shown in  FIG. 4 , there may include a plurality of doors  606  leading to different secondary areas. In some embodiments, one of the lower and upper portion  202 / 204  of truss  200  may be integrated into a wall  604 . 
       FIGS. 5A and 5B  show schematic section views of video display system  10 . As shown in  FIGS. 5A and 5B , for example, in some embodiments, truss  200  may include a pair of first beams  206  extending horizontally and parallel with a front surface of the video display  100 , a pair of second beams  208  extending vertically and parallel with the front surface of the video display  100  and coupled to the first beams. Lower portion  202  may be coupled to video display  100  at a position between the terminal sides  114  of the video display  100  and may extend approximately one third of the length of the video display  100 . In some embodiments, upper portion  204  of truss  200  may be positioned above lower portion  202  and anchored to a ceiling  602 , and upper portion  204  may be coupled to video display  100  at a position between terminal sides  114  of video display  100 .
