Abstract
The present invention provides a multiple seal electronic display module having displacement springs for distributed use as major components of an electronic sign. Displacement springs are provided to displace the electronic display module from the front of an electronic sign mounting panel until latching mechanisms are properly actuated in order to secure the electronic display module to the electronic sign mounting panel and thus provide a visual clue indicating proper or improper securing. A configured front edge seal provides for multiple surface sealing of multiple components consisting of, but not limited to, a louver panel, an LED circuit board, and a housing. A rear seal is also provided to seal the rear of the electronic display module to the electronic sign mounting panel. Input and output signal jack base seals and a power jack base seal provide effective seals between the housing and the signal and power jacks.
