An electronic sign having vertically hinged face panel doors which open individually about offset hinge assemblies and which aid in minimizing distorted seal compression. Individual door stop assemblies allow an operator to manageably open the face panel doors and to lock the face panel doors. In the open position, the face panel doors are protected from damage due to wind currents or gusts. The use of face panel doors having a parallelogram cross section profile allows for closely spaced face panel doors with a minimum panel-to-panel gap for uniform spacing and viewing of lighted pixel displays.
