1. A display arm, comprising:
a first end support for attachment to a support surface;
a second end support to a display;
an arm structure pivotally connected to at least the first end support and pivotable about an arm pivot axis, the arm structure extending from the first end support to the second end support;
a counterbalance mechanism including:
an energy storage device;
a block coupled to the energy storage device;
a counterbalance arm having a follower contacting the block, the counterbalance arm being pivotally coupled with the arm structure at a counterbalance pivot point on the arm structure, and the counterbalance arm being pivotable about a counterbalance pivot axis;
wherein a first angular displacement of the arm structure about the arm pivot axis induces a second angular displacement of the counterbalance arm about the counterbalance pivot axis, the first angular displacement being different from the second angular displacement.
