In this case, the rotation of the screen stops when the touch on the rotation center or the rotation point is released.

The screen rotation transparent layer is displayed when the rotation center and the rotation point are touched for a predetermined time or when the rotation speed is less than a predetermined speed, and includes a plurality of fine angles in the form of a compass. The plurality of minute angles are set in a menu displayed when the screen rotation transparent layer is touched.

The screen is rotated at an angle of 90 * n according to the rotation speed when the rotation speed with respect to the rotation point is more than a predetermined speed.

The screen rotation control method of the mobile terminal further includes the step of rotating the screen continuously by the minute angle displayed on the screen rotation transparent layer in the direction when the rotation point bounces in a certain direction. In this case, the rotation of the screen stops when the touch on the rotation center is released.

According to the present invention, when the user rotates the screen displayed on the touch screen, the user can not only control the rotation of the screen at a fine angle by rotating the screen according to the rotation speed or providing a transparent screen rotation layer. There are also advantages that can be applied to applications such as photo editing.
