A disclosed electronic device includes a housing having an opening, a roll mounted in the housing, a flexible display wound on the roll and being extendable and retractable through the opening based on a rotation direction of the roll, and a roll guide configured to guide the roll to move in a direction capable of constantly maintaining a proceeding direction of the flexible display toward the opening in the housing, based on a variation in a wound length of the flexible display on the roll.

Electronic apparatus having flexible display device

An electronic device includes a controller to receive a signal from an external electronic device, and, based at least in part on the received signal, identify a wireless power scheme among at least two wireless power schemes. During the transmission mode, the controller controls the full bridge circuit to convert DC power to AC power based on a wireless power frequency corresponding to the identified wireless power scheme by controlling at least one transistor of the full bridge circuit, and controls to wirelessly transmit power based on the AC power to the external electronic device. During the reception mode, the controller controls to receive power from the external electronic device, controls the full bridge circuit to convert the received power to DC power by controlling transistors of the full bridge circuit, and controls to provide the converted DC power for the battery of the electronic device.

Electronic device and method for wireless charging in electronic device

A method and power transmitter for efficiently controlling power transmission to one or more power receivers in a wireless multi-power transmission system are provided. The method includes performing, when a predetermined measurement cycle arrives, a load measurement; comparing a current load measurement value with a previous load measurement value; determining whether the current load measurement value is increased over the previous load measurement value by at least as much as a first predetermined threshold; gradually increasing, when the load measurement value is increased over the previous load measurement value by at least as much as the first threshold, a transmission power value until a request for a subscription to a wireless multi-power transmission network from a power reception target within a predetermined time limit; and stopping, when the request for the subscription is not received before the time limit is exceeded, power transmission to the power reception target.

Power transmitting method and power transmitter for communication with power receiver

A electronic device and a display method thereof are provided. A control method of the electronic device includes: detecting a touch input on an auxiliary display area; in response to a touch input being detected on a first area of the auxiliary display area in a and the electronic being in a state in which the electronic is gripped by a user, processing the touch input as a user input; and, in response to the touch input being detected on a second area of the auxiliary display area different from the first area and the electronic being in the state in which the electronic is gripped by the user, disregarding the touch input.

Electronic device with bent display and method for controlling thereof

An electronic device according to various embodiments of the present disclosure includes a power supply configured to supply DC power, a controller configured to determine a wireless power transmission mode or a wireless power reception mode if at least one electronic device is detected, and output a control signal indicating a wireless power transmission frequency supported by the detected electronic device from among a plurality of wireless power transmission frequencies if the wireless power transmission mode is determined, a conversion circuit configured to output the DC power supplied from the power supply as AC power in response to the control signal output from the controller and a wireless power transceiver configured to transmit the AC power supplied.

A plurality of panels include: a display panel; and a protective panel that is disposed outside the display panel, and includes a transparent substrate and an outer hard coating layer and an inner hard coating layer that are respectively formed on an outer surface and an inner surface of the transparent substrate, and each have a hardness greater than a hardness of the transparent substrate. A thickness of the outer hard coating layer is greater than a thickness of the inner hard coating layer, and a stress neutral surface of the flexible display device is configured so that a compressive stress is applied to the inner hard coating layer when the flexible display device is bent.

Flexible display device

A display apparatus is provided. The display apparatus includes a housing having an opening, a first roll and a second roll rotatably provided within the housing, a display configured to be wound on the first roll, and to be retracted and withdrawn through the opening according to a rotation direction of the first roll, a protection member configured to be wound on the first roll together with the display or to be wound in the second roll as the display is withdrawn from the housing, and a moveable component mounting part which is disposed between the first roll and the second roll and on which various components are mounted within the housing. The component mounting part moves within the housing to selectively provide space and utilize space according to a retraction operation and a withdrawal operation of the display.

Display apparatus

An apparatus and method are provided for transmitting and receiving power for wireless power transmission. A power transmitting apparatus includes a power supplier for generating power; a resonator for transmitting the power generated by the power supplier to a plurality of power receiving apparatuses; and a controller for determining whether a power transmission to a new power receiving apparatus is possible using a power receiving apparatus management table, when the new power receiving apparatus is detected while the power transmissions of the plurality of power receiving apparatuses are being performed, and controlling the resonator to transmit power to the new power receiving apparatus, when the power transmission to the new receiving apparatus is possible. The power transmitting apparatus stably supplies power to a plurality of power receiving apparatuses by determining power transmission states of the plurality of power receiving apparatuses.

Power transmitting and receiving apparatus and method for performing a wireless multi-power transmission

Methods and apparatus are provided for detecting a non-intended object of power reception by a power transmitter. Power transmission for communication is performed, when the load change is sensed that has a value greater than or equal to a predetermined threshold. It is determined whether a subscription request, for subscribing to a network is received within a predetermined time period. The power transmission for communication is stopped when the subscription request is not received within the predetermined time period. Power is transmitted to a power receiver that has transmitted the subscription request, when the subscription request is received within the predetermined time period. It is determined whether a leakage power value exceeds an allowable range, when the power state report is received from the power receiver. The transmission of the power to the power receiver is stopped, when the leakage power value exceeds the allowable range.
