A compound torque hinge comprising a first rotating shaft rotatably mounted through a partition wall within a hinge case having the partition wall; a first rotation control working on the first rotating shaft and mounted on one side of the partition wall of the hinge case; and a second rotation control mean coaxially mounted on the other side of the partition wall of the hinge case. The first rotating shaft is connected to the second rotating shaft of the second rotation control. The first rotating is a cam mechanism provided with spring and the second rotation control is a fluid damper.
