A battery in a mobile phone cover may be selectively charged according to a user-selectable parameter. When charged, the battery in the mobile phone cover may be used to charge a battery in a mobile phone.

A system can include a tablet computer that includes a tablet display; and a clamshell computer that includes a keyboard housing, a display housing and a hinge assembly that rotatably couples the keyboard housing and the display housing, where the display housing includes a display viewable via a display side, an opposing back side, and a tablet computer recess disposed between the display side and the back side that removably receives the tablet computer.

Provided is a printing device that performs printing using a recording material, the printing device including: an capacitive touch panel; a home operation portion including a mechanical key for transitioning from a screen displayed on the capacitive touch panel to a basic screen including information on a remaining amount of the recording material; and a power supply operation portion including a mechanical key for shifting a power state of the printing device, in which the home operation portion is closer to the capacitive touch panel than the power supply operation portion.

According to various examples of the present invention, an electronic device for controlling a plurality of displays can comprise: a first display for displaying a first screen; a second display for displaying a second screen; and a control unit for determining attributes of the first screen and the second screen, for determining whether to display, on a display that does not enter into an idle mode, a screen displayed on a display that enters into the idle mode in correspondence to the entry into the idle mode of either the first display or the second display, and for controlling the first display or the second display such that the first screen or the second screen is displayed thereon. In addition, various other examples are possible.

A computing device can be reconfigurable to include one or more electrical devices in various configurations. The computing device can include a base forming an input surface configured to receive user input. The base can receive one or more input devices, such as, displays or keyboards. The base can include a hinge rotatably attached to the base and configured to removably retain an electronic device, such as, a display. The computing device can include a coupling mechanism having a first retaining portion and a second retaining portion rotatably coupled to an intermediate portion. The first and second retaining portions can be configured to removably retain electrical devices to the coupling mechanism.

An electronic device of the present disclosure includes: one or more wireless communication modules that transmit and receive radio waves to and from an external device; an output controller that controls outputs of the one or more wireless communication modules; a state detector that detects a use state of the electronic device; and an identification (ID) identifier that identifies ID information. The output controller controls the outputs of the one or more wireless communication modules based on the use state detected by the state detector and the ID information identified by the ID identifier.

A detachable electronic device and a dock thereof are provided. The detachable electronic device includes a first machine body, a second machine body, and a dock. The dock includes a pair of fixing brackets, a pair of rotating axles, a latch module disposed between the rotating axles, a lock base, and a linkage kit. The latch module can be arranged in a locked state or an unlocked state to lock or release the second machine body. The lock base is slidably disposed on one of the fixing brackets. The linkage kit has one end fixed to the latch module, and the other another end slidably sleeved onto the lock base. When an anti-theft lock is locked to the lock base, the lock base restricts a displacement of the linkage kit, and the linkage kit restricts the latch module to the locked state.

A portable electronic device including a main display and at least one external display detachable relative to one side of the main display is provided. The external display includes a body, a slider slidably disposed in the body, at least one latch pivoted to the body, and at least one elastic member connected between the slider and the body. The latch has a driving column and a tenon portion opposite to each other, and the driving column is movably connected to the slider, such that when the slider slides relative to the body, the latch is driven to pivot relative to the body, and the tenon portion is rotated out of the body or hidden in body. The tenon portion that is rotated out of the body is inserted into the main display, so that the external display is combined to the main display.

A flexible display of a flexible display device can be divided and have removable sections for use as one or more wearable devices. The flexible display can be divided into a plurality of portions. The plurality of portions are divided along a plurality of dividing lines each having a locking mechanism, respectively. A power supply is electrically connected to the locking mechanisms to activate and deactivate the locking mechanisms. A portion of the plurality of portions border corresponding locking mechanisms along corresponding dividing lines of the plurality of dividing lines. The portion is selectable for decoupling and removal, in response to deactivation of the corresponding locking mechanisms for the portion of the flexible display.
