The invention discloses a method for controlling the three-dimensional switching of a display interface, which can be applied in middle and low-grade hardware platforms. The method comprises the following steps: determining the horizontal and vertical coordinates of a first boundary point (F) according to the expressions shown in the specification, wherein when theta is greater than or equal to pi and less than 3pi/2, x is a negative value, when theta is greater than 3pi/2 and less than or equal to 2pi, x is a positive value, when theta is equal to 3pi/2, x is zero, y is minus b, a is L1/2, b is a value in the interval of (0, L2/2), and L1and L2 are respectively the pixel per inch (along the width direction) of an effective display area (ABCD) of a display screen and the pixel per inch (along the height direction) of the effective display area (ABCD); defining the horizontal and vertical coordinates (x, y') of a second boundary point (E), wherein x is the horizontal coordinate of the first boundary point (F), the vertical coordinate y' of the second boundary point (E) is a value in an interval of (0, L2-b); displaying a new display interface in a first tetragonum (JFEI), and displaying the original display interface in a second tetragonum (FKLE) by using an image compression method; and dereferencing pi in the interval of (pi, 2pi), determining one display status by one theta value, and sequentially displaying the display statuses in the effective display area (ABCD) of the display screen so as to realize the three-dimensional switching of the display interface.
