The invention discloses a method for realizing a 3D (three-dimensional) function menu of a mobile phone, which is characterized in that a 2D (two-dimensional) icon of each function key is called through a master-model interface module of a 3D turntable, the 2D icons of the function keys are sequentially arranged in a 3D display mode of the turntable, the 2D icon of each function key selected by users is rotated in a clockwise or anti-clockwise sequence through a special effect processing module for the rotation of the 3D turntable, and the 2D icons are displayed in the foreground or background of the function menu, and the 2D icons of all function keys are arranged in a candidate mode, so that all the function keys are always in a visible state, and the number of the function keys is not restricted. When a user selects to enter some function interface, all the 2D icons of function keys on the current function interface are presented to the user in a dynamic special effect mode, such as dynamic simulation meteorological images of weathers, the sending, returning and shutter-type special sliding effects of short messages, and the like.
