    Abstract: A method of display rotation by using axis ratio and difference is disclosed. The method includes: performing a first determination step to determine whether or not two touching points exist within an object shown in a screen by using a touch algorithm; if yes, capturing X-coordinate values and Y-coordinate values of the two touching points on an X-axis and a Y-axis respectively; performing a second determination step to determine the touching point with smaller Y-coordinate value as an axle center point and the another touching point with bigger Y-coordinate value as a rotation point; performing a third determination step after the rotation point shifts to rotate object leftward or rightward by using the modulus of the variation of the ratio of the Y-coordinate value to the X-coordinate value of the rotation point and whether the axle center point and the rotation point are located on the X-axis or Y-axis.
