An auto-return pivot system for a display apparatus is provided. The auto-return pivot system comprises a base fixed to an article; a pivot fixed to the base; a support pivotally mounted around the pivot for supporting the display apparatus; a cam device connected with the support to determine a stop angle and an auto-return angle between the article and the support; and a pressure-storing device connected with the cam device for storing a pressure to be applied to the cam device in the axial direction of the pivot; wherein the pressure from the pressure-storing device enables the cam device to drive the support to automatically return to a position with the stop angle when an angle between the article and the support is smaller than the auto-return angle.
