Mobile wireless communications device with reduced interfering energy from the display and related methods

An electronic device comprising:

• a circuit board;
• a processor coupled to said circuit board, wherein the circuit board includes a cellular transceiver;
• a display connector coupled to said circuit board wherein the cellular transceiver is isolated from the display connector by an isolation structure surrounding the cellular transceiver;
• a microphone coupled to the circuit board, wherein the microphone is isolated from the cellular transceiver by a second isolation structure;
• a plurality of display connection lines interconnecting said processor, and said display connector carried by the circuit board;
• and
• a plurality of filters with each filter arranged as a filter array and coupled to a respective one of the plurality of display connection lines, wherein the plurality of filters are tuned to reduce radio frequency electromagnetic interference (EMI) generated by the electronic device.
