Abstract
Electronic alpha-numeric or symbol sectional display system featuring readily accessible access to internally located modular display and other components for quick changeout of modular and other components. Display panels, which are modular, having side-by-side display module/nested frame assemblies which include outer and inner nested frameworks, fine mesh screen, display circuit boards with LED character block displays, and driver circuit boards, are readily and quickly secured in stackable enclosure cabinets by the use of 1/4 turn or other quick fastening hardware. Other changeout friendly hardware is incorporated within to promote economy of manufacturing and changeout functions. Viewability of alpha-numeric or other symbol information is preserved and enhanced by the use of small panel fine mesh screens which maintain planar attributes and which are located at the front of each modular display panel residing in close proximity to the LED character block displays. Spacing of LED character blocks from one modular display panel to an adjacent or stacked modular display panel is constant and consistent along the width and breadth of the sectional display system.
