An electronic device is provided. The electronic device includes a first housing, a second housing slidable relative to the first housing, a contact member disposed in the first housing, a pressure sensor disposed in the second housing to face the contact member and provided in a state in which at least a portion of the pressure sensor is in contact with the contact member, a printed circuit board (PCB) disposed in the second housing, an actuator configured to drive the second housing, and a processor disposed on the PCB, electrically connected to the pressure sensor and the actuator, and configured to control the actuator, based on pressure information sensed by the pressure sensor.

A mobile terminal, a control system and a control method, the mobile terminal includes a housing and a flexible screen, the flexible screen includes a fixed portion fixed on the housing and an expansion portion movable relative to the housing; the mobile terminal further includes a support structure and a movement mechanism, the movement mechanism is configured to drive the expansion portion to move so that at least a part of the expansion portion is driven to move outside the housing; and the movement mechanism is capable of driving the expansion portion to move in an opposite direction so that the expansion portion outside the housing is driven to retract into the housing; and the support structure is configured to support the expansion portion.

An electronic device is provided. The electronic device includes a main body, a rotating member, a flexible display screen, and a flexible circuit board. The main body has a pillar shape. An outer periphery of the main body has a groove provided thereon. The rotating member is sleeved on an outside of the main body and is configured to drive the flexible display screen to be wound or unfolded relative to the rotating member. When the flexible display screen is unfolded, the flexible circuit board is unfolded along with the flexible display screen, and when the flexible display screen is wound, the flexible circuit board is wound into the groove along with the flexible display screen.

A mobile terminal comprises a display unit that may be subjected to bending deformation in a first direction, and a rolling plate attached to a rear surface of the display unit, enabling bending deformation to correspond to bending deformation of the display unit, wherein the rolling plate includes a plurality of support bars extended in a second direction vertical to the first direction and arranged in parallel in the first direction, and an expanded side portion arranged at an end portion of the plurality of support bars, and the expanded side portion includes a guide bump engaged with its adjacent expanded side portion. Since the rolling plate supporting the display unit is not twisted by rotation, the display unit may maintain a flat state.

An electronic device includes a first housing provided with a first sliding portion and a second housing slidably arranged on the first housing along a first direction, the first housing and the second housing being enclosed to form a receiving structure with an opening; a flexible display screen having a first end arranged at a side close to a bottom of the housing and a second end connected to the first housing to cover the opening; and a sliding rail mechanism including a bracket connected to the flexible display screen and provided with a second sliding portion matching the first sliding portion, the first sliding portion being one of a sliding rail and a sliding groove, the second sliding portion being the other.
