Handheld electronic device

A mobile phone comprising:

• a housing member;
• a rear cover coupled to the housing member;
• a front cover coupled to the housing member and defining an exterior surface and an interior surface opposite to the exterior surface;
• a display stack attached to the interior surface of the front cover and comprising a flexible circuit element defining a loop extending from an upper portion of the display stack to a lower portion of the display stack;
• a frame member attached to the interior surface of the front cover and extending at least partially around a periphery of the display stack;
• and
• a polymer potting material defining:
• a first portion positioned in a region between the frame member and an outer surface of the loop of the flexible circuit element;
• and
• a second portion positioned in the loop of the flexible circuit element.

A portable electronic device comprising:

• a housing member;
• a rear cover coupled to the housing member and defining at least a portion of a rear surface of the portable electronic device;
• and
• a top module coupled to the housing member and comprising:
• a front cover defining an exterior surface and an interior surface opposite to the exterior surface, the exterior surface defining at least a portion of a front surface of the portable electronic device;
• a display stack attached to the interior surface of the front cover and comprising a flexible circuit element defining a loop extending from a peripheral side of the display stack;
• and
• a molded polymer structure bonded to the interior surface of the front cover and at least partially encapsulating an exterior portion of the loop, the molded polymer structure coupled to the housing member, thereby coupling the top module to the housing member.
