Abstract: A deformable display device and a deformation control method therefor are provided. The deformable display device includes a flexible display screen and a deformation control structure configured to drive the flexible display screen to deform. The deformable display device has a first mode and a second mode. A first distance between a first point of the flexible display screen and a reference point in the first mode is not equal to a second distance between the first point and the reference point in the second mode. The reference point is a point on the deformation control structure. A position of the reference point remains unchanged when the deformable display device is switched from the first mode to the second mode. A display surface, on which the first point is located, of the flexible display screen intersects a line connecting the first point with the reference point.
