Method of manufacturing a door frame subassembly for an electronic display assembly

A method of manufacturing a door frame subassembly for an electronic display assembly, said method comprising:

• extruding metal for a frame, including forming a perimeter surface and a ledge for receiving a cover layer of the electronic display assembly, where the ledge is recessed from an upper edge and a lower edge of the perimeter surface such that at least a majority of the perimeter surface, including the lower edge, extends on a first side of the ledge and where the ledge extends outward at least substantially perpendicular from, and extends along, an interior facing surface of the perimeter surface;
• bending the extruded metal into a rectangular shape with rounded corners defining an opening with a remaining gap, wherein the recessed ledge extends into said opening;
• joining the remaining gap;
• installing said cover layer to a first surface of said recessed ledge facing said upper edge, wherein the cover layer is transparent or translucent;
• and
• installing said door frame subassembly to a remainer of the electronic display assembly such that said cover layer is positioned forward of an electronic display layer of the electronic display assembly and a second surface of said recessed ledge opposing said first surface faces an interior of the electronic display assembly and said lower edge of said perimeter surface.
