Mobile wireless communications device with reduced interfering energy from the display and related methods
First Claim
1. A mobile wireless communications device comprising:
- a housing;
a circuit board carried by the housing and including radio frequency (RF) circuitry and a processor carried by the circuit board and operative with each other;
a display connector mounted on the circuit board and adapted to be connected to a display;
display connection lines carried by the circuit board and interconnecting the display connector and the processor for carrying signals from the processor for display on a display connected to the display connector; and
filters carried by the circuit board and connected into the display connection lines for reducing any interfering energy from the processor and a display into the display connection lines.

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 by 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 display connection lines and reduce any interfering energy from the processor and display.
