A linear drive has at least one rack which is arranged along a longitudinal axis and has a plurality of teeth, a drive shaft arranged in a transverse axis transversely to the longitudinal axis, and at least two propulsion elements, each having at least one propulsion tooth. The at least two propulsion elements are linearly movable in a stroke axis which is oriented transversely to the longitudinal axis and transversely to the drive shaft. The at least two propulsion elements are drivingly coupled to the drive shaft in such a manner that the at least two propulsion elements perform at least one cyclical stroke movement in the course of one rotation of the drive shaft and enter and exit the at least one rack to generate a propulsion in the longitudinal axis. The at least two propulsion elements enter and exit the at least one rack with a phase shift.

A secondary display may be integrated into a form factor of an information handling system having a primary display in a manner that synchronizes movement of the secondary display with the primary display. The secondary display may move from a closed position to an open position along with moving of a primary display from a closed to an open position. A rack and pinion mechanism may synchronize the secondary display with the primary display through a first and second primary pinion coupling a primary shaft of the primary display to a rack. A secondary pinion may couple a secondary shaft of the secondary display to the rack. Movement of the secondary display may be synchronized with movement of the primary display through the rack and pinions.
