An electronic display assembly includes a housing with a pass-through device which accepts a utility line. One or more electronic display subassemblies are placed within said housing and a are surrounded by a substantially sealed closed loop pathway. An open loop pathway permits ambient air to pass through said housing and thermally interact with said closed loop pathway without mixing. At least two peripheral devices are located within said housing, one of which is a charging subassembly and the other is selected from the group consisting of: a camera, a touchscreen, an additional electronic display, video communications equipment, audio communications equipment, and an emergency notification subassembly.
