FIELD OF THE DISCLOSURE 
     The present disclosure relates to display systems. More specifically, the present disclosure relates to video display systems associated with electroacoustic devices. 
     BACKGROUND OF THE DISCLOSURE 
     Electronic displays for use in advertising are well known in the art. Such electronic displays find use in advertising applications in a variety of environments. In recent years, flat-panel display technologies have been developed, such as plasma, LCD, LED and other types of vertically mounted displays, such as may be used in forming billboards or secured to vertically extending structures or vertically suspended from such structures for use with other public venues. 
     However, known video displays, particularly for advertising on billboards and similar structures, can be large, requiring large amounts of space and separate electrical requirements. 
     Therefore, there is an unmet need to provide a display system associated with a public venue and/or a public performance, making at least partial use of already existing components and power/resources. The display system should also improve the effectiveness or quality of the system&#39;s use with the public venue and/or public performance. 
     SUMMARY OF THE DISCLOSURE 
     One aspect of the disclosure includes a video display system including an electroacoustic device secured within a housing. A plurality of modules is operatively associated with the housing and is arranged to form a display area, each of the modules including at least one light source. The modules cooperatively display light to display at least one of video and images. 
     A further aspect of the disclosure includes a method of displaying video. The method further includes providing a video display system including an electroacoustic device secured within a housing, and a plurality of modules associated with the housing and being arranged to form a display area, each of the modules including at least one light source. The method further includes cooperatively displaying light with the modules to display at least one of video and images. 
     An advantage of the present disclosure is a video display system that at least partially makes use of existing components and power/resources associated with the system. 
     Another advantage of the present disclosure is a video display system that uses electroacoustic devices secured within a housing to form a video display from modules including at least one light source for cooperatively displaying light to display at least one of video and images, while permitting substantially unobstructed acoustical communication through the housing. 
     It is to be understood that one or more of the above-referenced advantages may be contained in an exemplary embodiment of the present disclosure. 
     Further aspects of the method and system are disclosed herein.
