Abstract:
1. An apparatus comprising: a display module; an actuator connected to the display, the actuator being configured to apply a first force in a first direction to the display module; and at least one counterweight connected to the actuator, the actuator being configured to apply a second force in a second direction to the counterweight, wherein the apparatus experiences substantially no translational moment; wherein the actuator comprises a first piezo-electric actuator connected at substantially a first end to a first counterweight, substantially at a second end to a second counterweight, and at least one further point to the display module; and wherein the actuator comprises a second piezo-electric actuator connected at substantially a first end to the first counterweight, at substantially a second end to the second counterweight and at least one further point to the display module on an opposite side to the display module to the side of the display module connected to the first piezo-electric actuator.
