A flexible display device includes: first and second casings; a frame movably assembled to the second casing; and a flexible display having first and second ends opposite to each other and first and second display areas. The second casing is movably assembled to the first casing to form a drawer configuration and slide relative to the first casing to switch between drawn-out and retracted states. The first end is connected to the first casing. The second end to the frame. In the retracted state, the flexible display is bent so the second display area is contained in the first and second casings. In a process from the retracted state to the drawn-out state, the second casing is drawn out from the first casing and drives the frame to move in the same direction to expand and flatten the second display area. A portable electronic device is also provided.

A hinge is mountable on a flexible display unit including a housing shell unit and a display unit. The hinge includes a base seat, a torsion module disposed above the base seat and secured to the display unit, and a bracket module disposed below the base seat. The torsion module includes two outer supporting units and an inner supporting unit at two ends and a middle of the base seat. The bracket module has two brackets securely connected to two support plates of the display unit and rotatable relative to the base seat. The hinge is rotatable between an unfolded position where the brackets are in an unfolded state, and an outfolding position where the brackets are close to and face each other. The outer and inner supporting units cooperatively define a semicircular-shaped supporting surface in the outfolding position for supporting the display unit.

A flexible display device is provided. The flexible display device includes a first housing, a second housing, a rolling mechanism, a flexible display screen, and a support plate mechanism. The flexible display screen can be retracted or expanded relative to the rolling mechanism. When the flexible display screen is completely expanded, a second support surface of a support plate and a first support surface of the second housing support the flexible display screen with their whole surfaces, thereby preventing the flexible display screen from collapsing and deforming.

An electronic device is provided. The electronic device includes a first cover, a second cover coupled to the first cover to slide, a display in which a size of an exposed region is changed corresponding to the sliding of the second cover, a panel support disposed on one side of a back surface of the display with respect to a front surface of the display on which a screen is displayed, and a rotation shaft contacting at least a portion of the panel support and rotating corresponding to the sliding of the second cover, and an attractive force may be formed between the portion of the rotation shaft and the portion of the panel support.

An electronic device includes a display module including a first region and a second region which extends from the first region and tactically senses an input via a conductive layer, a first structure facing the display module, a second structure slidably connected to the first structure, and slidable together with the display module along the first structure, and a back cover forming a rear surface of the electronic device and including a window region, and the conductive layer which is on the window region. The second structure which slides towards and away the first structure respectively closes and opens the electronic device, the electronic device which is closed defines the front surface including the first region, together with the second region tactically exposed at the window region, and the electronic device which is open defines the front surface including the first region and a portion of the second region.

An electronic device may include a first housing, a second housing configured to accommodate at least a part of the first housing and guide sliding movement of the first housing, a flexible display including a first display area coupled to the first housing and a second display area extending from the first display area, a gear disposed inside the second housing and configured to move the flexible display, a motor configured to rotate the gear, at least one sensor, and at least one processor. The at least one processor may be configured to identify a state of the electronic device including at least one of a battery current, a battery voltage, an internal consumption current, a battery level, or an electronic device temperature, based on information sensed through the at least one sensor, and control a speed of the motor or discontinue driving of the motor based on the state of the electronic device.

The present disclosure provides a mobile terminal capable of expanding a display unit, and a control method therefor. When an event occurs, the mobile terminal of the present disclosure provides a user with convenience by enabling the user to select whether to expand the display unit upon execution of the event. Specifically, the event can be the execution of a specific application or the reception of a notification related to a call or a message.

The present disclosure provides an attachable external display screen for use on electronic devices. The display screen may be removably mounted onto a surface of an electronic device to provide the user with an additional display screen. The attachable display screen may utilize a dual sliding mechanism that allows for the display screen to slide out to different lengths relative to the screen of the electronic device. The attachable display screen may also utilize a torque hinge to pivotally couple the display screen to a frame that mounts onto the electronic device. The attachable display screen is rotatable about both the horizontal and vertical axes, which allows a user to tilt and adjust the angle of the display screen.

Methods and systems for determining a position of a structure using inductive position sensing are described. In an example, a processor may receive a plurality of data points representing a plurality of voltages. The plurality of voltages may be generated by a plurality of sensor coils based on a magnetic flux field. The magnetic flux field may be generated by a plurality of driver coils, and the plurality of voltages may vary with changes in the magnetic flux field. The processor may calibrate the plurality of data points to generate a plurality of calibrated data points. The processor may filter the plurality of calibrated data points. The processor may estimate a position of the structure based on the filtered calibrated data points, where the position of the structure may indicate a size of a size changing device.

This application provides an electronic device with a rollable display. The electronic device includes a device body, the rollable display, and a support assembly. A display area is formed on at least one side surface of the device body. The device body has an initial display state, the device body can be enabled to extend to another extended display state, and an area of the display area in the initial display state is less than an area of the display area in the extended display state. The electronic device not only meets a normal use requirement of a user, but also increases a display area of a display screen, and supports the display screen with a larger display area.
