A method for controlling a mobile terminal according to another embodiment of the present invention is applied to the mobile terminal in the above embodiment, and the method for controlling a mobile terminal includes:

responding to a telescopic instruction, and determining the current proportion of the flexible screen 100 of the mobile terminal, wherein the telescopic instruction carries a target proportion;

judging whether the current proportion is consistent with the target proportion;

if the current ratio is not consistent with the target ratio, a control signal is sent to the telescopic assembly 300 of the mobile terminal, and the control signal is used for instructing the first telescopic part 301 and the second telescopic part 302 to move so as to enable the first supporting part 201 and the second supporting part 202 to approach each other and to move away from each other, so as to adjust the flexible screen 100 to the target ratio.

According to the control method of the mobile terminal of the embodiment of the invention, as the first telescopic part 301 and the second telescopic part 302 can move in opposite directions, the first supporting part 201 and the second supporting part 202 can be controlled to drive the first end of the flexible screen 100 and the second end of the flexible screen 100 to approach to and separate from each other, so that the use size of the flexible screen 100 can be adjusted to meet the use requirements of users in different scenes, and the applicability is better. In addition, since the first telescopic part 301 and the second telescopic part 302 can move in opposite directions, the movement stroke of the telescopic assembly 300 can be reduced, and the reliability and stability of the mobile terminal in size adjustment are improved.

It will be appreciated that the current and target ratios are the ratio of the length to width directions of the flexible screen 100 in use. For example, the target ratio may be 16.

Specifically, if the current ratio is smaller than the target ratio, that is, if the flexible screen 100 of the mobile terminal needs to increase its size in the length direction:

the control signal controls the first driving part 3031 and the second driving part 3032 to rotate simultaneously; the first driving part 3031 drives the first screw 3011 to rotate, the first screw 3011 drives the first supporting part 201 to move forward to drive the first end of the flexible screen 100 to extend forward, the second driving part 3032 drives the second screw 3021 to rotate, and the second screw 3021 drives the second supporting part 202 to move backward to drive the second end of the flexible screen 100 to extend backward.

The control signal controls the fourth driving member 502 to rotate so as to drive the second driving wheel 501 to rotate, and the second driving wheel 501 can assist the second end of the flexible screen 100 to slide along the outer peripheral surface of the second supporting portion 202, so that the flexible screen 100 extends in two directions along the length direction thereof.

If the current ratio is larger than the target ratio, that is, the flexible screen 100 of the mobile terminal needs to be reduced in size in the length direction.

The control signal controls the first driving part 3031 and the second driving part 3032 to rotate simultaneously; wherein, first driving piece 3031 drives first screw 3011 to rotate, and first screw 3011 drives first supporting part 201 and moves backward to drive the first end of flexible screen 100 and roll backward, and second driving piece 3032 drives second screw 3021 to rotate, and second screw 3021 drives second supporting part 202 and moves forward to drive the second end of flexible screen 100 and roll forward, thereby reduces the length direction's of flexible screen 100 size.
