Display method and display device of arbitrary angle plane rotation

The invention provides a display method of arbitrary angle plane rotation. The display method of the arbitrary angle plane rotation comprises the following steps: according to a reference coordinate and a practical coordinate, obtaining an inclination direction and an inclination angle of a display device; according to the inclination angle, obtaining the display dimension of a display picture; and after the display picture rotates at the inclination angle by taking a display center point as the center along a direction opposite to the inclination direction of the display device, displaying according to the display dimension. The invention also provides a display device. The display method and the display device of the arbitrary angle plane rotation can carry out rotation display on any angle plane, can display the integral display picture with the maximum dimension according to the inclination angle and are high in user experience. 本发明提供一种任意角平面旋转显示方法，所述任意角平面旋转显示方法包括根据参考坐标及实际坐标获取显示装置的倾斜方向及倾斜角度；根据所述倾斜角度获取显示画面的
