Abstract

A tilter assembly is provided for positioning an electronic device such as a flat panel display. The tilter assembly includes a tilter shaft holder having an opening aligned along an axis and a shaft received within the opening. The shaft is rotatable about the axis, and may be coupled to a support. The tilter shaft holder is coupled to the electronic device. The tilter assembly also includes a torsion spring device in operative association with the shaft to provide a bias or counterbalance to the electronic device, thereby preventing undesired rotation about the axis. The torsion spring device may be adjustably tensioned by a tension mechanism.
