     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention pertains to electronic displays and, in particular, relates to large scale electronic displays which are subjected to heavy wind loading. Reinforced light emitting structure in the form of adjacent and connected modular face panel assemblies extends across a large clear span area and maintains uniform pixel spacing without the requirement of intermediate structure. 
     2. Description of the Prior Art 
     Prior art sturdily constructed electronic displays were constructed having intermediate structure between light panels which paid little attention to uniform and even pixel spacing, or, if no intermediate structure was visible from the front, the light emitting structure was such that changeout of components was required by frontal access only, as support structure behind the light emitting structure often hampered rearward access. 
     The present invention, a panelized/modular electronic display, provides a modular electronic display which is sturdily constructed to withstand heavy wind loading and which overcomes difficulties encountered in prior art devices. 
     SUMMARY OF THE INVENTION 
     The present invention is a panelized/modular electronic display system capable of withstanding high wind loading. A substantial framework and walk-in or rear access enclosure provides a large clear span area for accommodation of a series of connected face panel assemblies which secure therein. The major structure of each face panel assembly, which is modular, is a vertically aligned channel which has columns of apertures and a polycarbonate face secured to the inward surface thereof. Planar reinforcement bars are secured between the channel sides to form vertically oriented laminated and reinforced cross section junctions, thereby imparting strength to the series of connected modular face panel assemblies. Modularity is also enhanced by a plurality of LED modules which secure by quarter-turn hardware to the rear of each modular face panel assembly. Geometrical configurations are incorporated for uniform spacing of the pixels with respect to vertical and horizontal alignment. Uniform pixel display is maintained from left to right by the relationship of the vertical sides of each modular face panel assembly, and uniform spacing is maintained vertically by interlacing of the upper and lower edges of adjacent vertically aligned LED modules. 
     According to one embodiment of the present invention there is provided a panelized/modular electronic display including a sturdy framework, a large clear span area within the framework which accommodates a series of vertically aligned and connected modular face panel assemblies, laminated and reinforced cross section junctions common to and formed by members of adjacent modular face panel assemblies, and a plurality of LED modules aligned to the rear of each modular face panel assembly. An alternate embodiment involves a thin profile panelized/modular electronic display having a plurality of rear located access doors. 
     One significant aspect and feature of the present invention is a panelized/modular electronic display which is able to withstand high wind loading. 
     Another significant aspect and feature of the present invention is a panelized/modular electronic display which includes modular face panel assemblies. 
     Yet another significant aspect and feature of the present invention is a panelized/modular electronic display which includes modular LED assemblies. 
     An additional significant aspect and feature of the present invention is a panelized/modular electronic display which includes laminated and reinforced cross section junctions common to adjacent modular face panel assemblies to provide structural integrity when subjected to wind loading. 
     A still additional significant aspect and feature of the present invention is a panelized/modular electronic display having rearwardly located accessibility to modular LED assemblies. 
     A further significant aspect and feature of the present invention is a panelized/modular electronic display having vent chambers for cooling of the modular face panel assemblies and of the modular LED assemblies and removal of solar heat gain. 
     A still further significant aspect and feature of the present invention is a panelized/modular full matrix electronic display which includes black painted metal face panel assemblies whose surface between the matrix of aperture openings provides sun shading for the internally mounted LED assemblies, and also a contrast background for the LED assemblies which enhances viewability, legibility, and readability of the LED messages displayed. The display appears to some people to be continuous to the visible eye, while other people can barely detect each modular face panel assembly, only after careful viewing. 
     Having thus set forth aspects and features of embodiments of the present invention, it is the principal object hereof to provide a panelized/modular electronic display capable of withstanding high wind loading.

The face panel stiffeners  48   a - 48   n  are horizontally distributed parallel to the module mounting rails  46   a - 46   n  and secure over and about the planar flanges  58  and  60  of each of the modular face panel assemblies  12   a - 12   c . The face panel stiffeners  48   a - 48   n  as well as the module mounting rails  46   a - 46   n  counteract any twisting moment of the modular face panel assemblies  12   a - 12   c  encountered under high wind loads and contribute to the structural integrity of the combined modular face panel assemblies  12   a - 12   c . Although the module mounting rails  46   a - 46   n  and face panel stiffeners  48   a - 48   n  are shown spanning only combined modular face panel assemblies  12   a - 12   c , the lengths of the module mounting rails  46   a - 46   n  and face panel stiffeners  48   a - 48   n  can be such that the entire combined width from modular face panel assembly  12   a  through modular face panel assembly  12   n  can be spanned by module mounting rails  46   a - 46   n  and face panel stiffeners  48   a - 48   n  of appropriate single length. 
     FIG. 12 illustrates an isometric view of the modular face panel assemblies  12   a - 12   c  including module mounting rails  46   a - 46   n  and face panel stiffeners  48   a - 48   n  where the modular face panel assemblies  12   a - 12   c  secure to the upper and lower framework members  32   a  and  32   b , respectively. Securement of the modular face panel assemblies  12   a - 12   c  at the upper and lower regions to the framework members  32   a  and  32   b  is accomplished by the use of pluralities of upper and lower brackets  106   a - 106   c  and  108   a - 108   c , respectively. Others of the modular face panel assemblies  12   a - 12   n  can also be attached in a similar fashion at the upper and lower regions and also joined together side by side along the large clear span length to form laminated and reinforced junctions  100  between successive modular face panel assemblies  12   a - 12   n , as previously described. 
     FIG. 13 illustrates a vertical cross sectional view illustrating the relationship of the LED module  36   b  to the modular face panel assembly  12   a . The plurality of LED pixel assemblies  72   a - 72   n  align with and are visible through the columns of apertures  65   a - 65   n . Tubular surround  110  houses a plurality of LEDs  112  and also provides a mounting structure and spacer between the display boards  66   a - 66   n . Illustrated in particular is the vent chamber  114  which is the space between the polycarbonate face  50 , the panel  64  of the LED module  36   b , the planar side  54  of the face panel  44  and the planar side  56  (FIG. 5) of the face panel  44 . Fans  38   a - 38   c  (FIG. 4) circulate air in the vent chamber  114  to remove solar absorption heat from the modular panel face assembly  12   a  and heat created by the LEDs  112  on the LED module  36   b.    
     FIG. 14 illustrates a top view of the parts shown in FIG. 5 assembled and thereby creating the vent chamber  114 . 
     FIG. 15 is an exaggerated cross sectional view taken along line  15 — 15  of FIG. 9 prior to hardware tightening illustrating the drip cap  42   a  secured over and about the lower edge of the polycarbonate face  50 . Moisture which can enter the apertures located in the columns of apertures  62   a - 62   n  can flow downwardly between the face panel  44  and the outwardly facing surface  50   a  of the polycarbonate face  50 . Downwardly flowing moisture flows into the drip cap  42   a  and exits through a plurality of drain holes  116   a - 116   n . Silicone or other suitable sealant  118  is applied between the top region of the drip cap  42   a and the lower region of the polycarbonate face  50  and between the lower region of the drip cap  42   a  and the lower and inner surface of the face panel  44  to prevent moisture from entering the region behind the face panel  44 . The vertical edges of the polycarbonate face  50  are also sealed as shown in FIG. 10 to prevent moisture from entering the region behind the face panel  44 . 
     FIG. 16, an alternative embodiment, illustrates a left side view in cutaway of a thin profile panelized/modular electronic display  120 . The thin profile panelized/modular electronic display  120  incorporates the majority of the features, components and structure of the panelized/modular electronic display  10  but is of a thinner profile for use in space-restricted mounting and display locations. A heavy framework  122  having many of the attributes of but of lesser depth than framework  32  is provided to enhance structural integrity with respect to wind loading and for mounting of components thereto.
