Abstract

A mobile wireless communications device includes a housing and circuit board carried by the housing and includes radio frequency (RF) circuitry and a processor carried by the circuit board and operative with each other. A display connector for an LCD connector is mounted on the circuit board and adapted to be connected to a display. Display connection lines are carried b y the circuit board and interconnect the display connector and processor for carrying signals from the processor to the display connector and a connected display. Filters are carried by the circuit board and connected to the displ ay connection lines and reduce any interfering energy from the processor and display.
