MODULAR SOLID STATE ELECTRONIC DISPLAY PANELS WITH ELECTROMAGNETIC RADIATION SHIELDING

摘要

A display module having electromagnetic interference shielding is disclosed. The display module has a mask circuit board disposed immediately above a first circuit board. One or more light emitting elements are disposed on a top surface of the first circuit board. The mask circuit board has one or more apertures which enable the light from the light emitting elements to radiate outward. The mask circuit board has one or more metalized layers electrically connected to ground which receive and reduces the electromagnetic radiation emitted from the first circuit board. The display module employs one or more shield strips disposed near the perimeter of the mask circuit board and first circuit board to receive and reduce the electromagnetic radiation which would otherwise radiate laterally from the circuit boards.
