Optionally, the mobile terminal comprises a housing 300, and the housing 300 comprises a first housing 310 and a second housing 320.

Referring to fig. 3, in the first embodiment of the present application, the driving device 600 includes a reel 500 and a driving assembly 600, optionally, the reel 500 is movably connected to the first housing 310; a driving assembly 600 is in driving connection with the housing 300 and the reel 500, and the driving assembly 600 drives the first housing 310 and the second housing 320 to reciprocate in a direction of facing or separating; and/or, the driving assembly 600 drives the reel 500 to rotate.

In this embodiment, the scroll 500 is rotatably disposed in the first housing 310 of the mobile terminal, and is used for the flexible display 400 to carry.

Optionally, the mobile terminal further comprises a flexible display 400 disposed on the housing 300; the flexible display screen 400 is mounted on the scroll 500, and the scroll 500 rotates to drive the flexible display screen 400 to switch between a retracted state and an extended state.

Optionally, the flexible display 400 has a retracted state and an extended state, which can be automatically switched by the driving assembly 600. The flexible display 400 includes a main screen portion and a sub-screen portion extending from one end of the main screen portion, and optionally, the sub-screen portion may be formed by extending from one end of the main screen portion in the length direction, and the main screen portion and the sub-screen portion are different portions of the same screen.

Alternatively, the main screen is a screen commonly used by users and may be fixed to the front (non-side) of the mobile terminal, and the width of the main screen portion is the same as or equivalent to that of the housing 300. The sub-screen portion is a retractable and expandable display screen disposed on two sides of the first end and the second end of the main screen of the mobile terminal, and the sub-screen portion rotates under the driving of the driving assembly 600 to be in a folded state or an expanded state with the main frequency portion.

Optionally, the mobile terminal has a first side and a second side opposite to each other, the main screen portion is disposed on the first side of the mobile terminal, the main screen portion is a side facing the user, the sub-screen portion is optionally disposed on the same side as the main screen portion under the driving of the driving assembly 600, and is also optionally disposed on the other side opposite to the main screen portion, i.e., the second side (the main screen portion and the sub-screen portion are folded).

Optionally, when the flexible display 400 is in the retracted state, the main screen portion fully extends over both ends of the housing 300 in the length direction, and at this time, when the first side where the main screen portion is located is taken as the front side, the sub-screen portion may be driven by the driving assembly 600 to move to the back side, that is, the sub-screen portion is the side away from the user, and at this time, the sub-screen portion is received in the housing 300. Optionally, the sub-screen portion is not active, i.e. black screen. When the flexible display 400 is in the unfolded state, the sub-screen portion moves toward the main screen portion, and part or all of the sub-screen portion is disposed on the same side as the main screen portion, so as to increase the width of the mobile terminal.

Alternatively, the driving assembly 600 may be controlled by an electronic control assembly in the mobile terminal to drive the flexible display 400 to automatically expand or contract. Optionally, the electronic control assembly may receive a key command, a voice command, a touch command, an action command, a gesture command, and the like triggered by a user, and control the driving assembly 600 to operate, so that the driving assembly 600 drives the flexible display 400 to operate in the extended state or the retracted state.

Optionally, in response to a control instruction received by the mobile terminal, when the control driving assembly 600 drives the flexible display screen 400 to change from the retracted state to the extended state, the flexible display screen 400 may control the main screen portion and the sub-screen portion to respectively display the first interface and the second interface in a dual-window mode, that is, the flexible display screen 400 may simultaneously display two interfaces, so as to implement the split screen setting. The flexible display screen 400 that expands can show two at least interfaces simultaneously, can make the display content of flexible display screen 400 richer like this, can promote the utilization ratio of flexible display screen 400 to promote user's visual experience. Optionally, in response to the flexible display 400 being converted from the folded state to the unfolded state, the main screen portion and the sub-screen portion of the flexible display 400 are controlled as a whole to display the same interface in a single window mode, for example, to watch a video or other application scenes requiring a large window.

Alternatively, the driving assembly 600 may drive the first housing 310 and/or the second housing 320 to move. Alternatively, the driving assembly 600 may drive the second housing 320 to move relative to the first housing 310, or the first housing 310 to move relative to the second housing 320, or both the first housing 310 and the second housing 320 to move together, so as to realize the movement of the whole device.

Alternatively, upon driving of the driving assembly 600, when the sub-screen portion moves away from the main screen portion, the first housing 310 and the second housing 320 may also synchronously approach each other, thereby controlling the flexible display screen 400 to shrink the display area of the flexible display screen 400. When the sub-screen portion moves toward a direction close to the main screen portion, the first housing 310 and the second housing 320 may also move away from each other in synchronization, thereby controlling the flexible display screen 400 to extend the display area of the flexible display screen 400. Based on this, the driving assembly 600 simultaneously drives the housing 300 and the flexible display screen 400 to move synchronously, so that the housing 300 can support and protect the flexible display screen 400, and the technical effect of flexibly adjusting the area of the display screen according to the requirement is achieved.

Based on this, the driving device of the embodiment of the application drives the scroll 500 and the flexible display screen 400 to move synchronously through the driving assembly 600, so that the scroll 500 can rotate, and thus the flexible display screen 400 rotates out of the housing 300 and is laid on the unfolded housing 300, thereby realizing the expansion of the display area of the display screen. The method and the device are beneficial to improving the service life and the reliability of the mobile terminal.
