A display apparatus including a communication module comprising circuitry; a display; a motor configured to rotate the display; a user input module; a memory storing at least one instruction; and a processor in communication with the communication module, the display, the motor, the user input module, and the memory to control the display apparatus. The processor, upon execution of the stored at least one instruction, is configured to control the display to display a first screen based on the display being placed in a first orientation, and based on a first user command being input through the user input module while the first screen is displayed, control the display to display at least one second screen having a history of being displayed on the display and information on the display orientation of the at least one second screen being displayed.

An electronic device includes a first body, a second body coupled to the first body, a trigger device, and a processing device. The trigger device is configured to generate a trigger instruction based on a trigger operation. The trigger device is placed in an area that is responsive to a movement of the first body relative to the second body. The processing device is configured to switch the electronic device from a first state to a second state in response to the trigger instruction. A power consumption state of the first state is different from a power consumption state of the second state.

A portable information handling system rotationally couples main and lid housing portions to each other with a hinge having opposing faces. One of a first or second antenna set disposed on the opposing faces is selected to support wireless communication by a radio disposed in the housing based upon the rotational orientation of the hinge. Optimal antenna selection is confirmed by comparing return signal strength indicator or bit rate error of the first and second antenna sets.

An electronic device having a concealable camera includes a shell, as well as an image capturing assembly and a retractable reflecting component arranged in the shell. An opening through which the reflecting component extends out of the shell is formed in the shell, and the reflecting component is configured to, during mage capturing, extend out through the opening and reflect a received mirror image onto the image capturing assembly for imaging of the image capturing assembly.

An electronic device is provided. The electronic device includes a function module, a body, and a motor assembly. The body includes an accommodation space for accommodating the function module. The motor assembly includes a drive motor, a gear, a rotation output shaft, a displacement mechanism, and a latch. The drive motor includes a shaft. The gear is fixedly attached to the shaft. The rotation output shaft includes a gear teeth portion. The gear teeth portion is coupled to the gear. The rotation output shaft is connected to the function module and is configured to drive the function module to rotate. The displacement mechanism synchronizes with the shaft and is separated from the rotation output shaft. The displacement mechanism includes a linear motion component. The latch is connected to the linear motion component, and is configured to engage the function module.

A display apparatus and a control method thereof are provided. The display apparatus includes a display configured to be rotatable; a plurality of cameras; and a processor configured to: based on the display being oriented in a vertical direction, control one camera of the plurality of cameras to perform photographing; and based on a user command being received while the one camera is performing photographing, rotate the display to be oriented in a horizontal direction and control the one camera to stop photographing.

A portable information handling system rotationally couples main and lid housing portions to each other with a hinge having opposing faces. One of a first or second antenna set disposed on the opposing faces is selected to support wireless communication by a radio disposed in the housing based upon the rotational orientation of the hinge. Optimal antenna selection is confirmed by comparing return signal strength indicator or bit rate error of the first and second antenna sets.

One-touch transmission and one-touch silencing of a wearable group communication device utilize an end user device body and face that can be moved relative to one another in one or more simple, single-motion actions. One-touch audio transmission is enabled after an end user device is activated to enable communications. Depressing the end user device face relative to the end user device body enables audio transmission. While the face is in its depressed position audio can be transmitted. To cease audio transmission the face is released. One-touch audio silencing of an activated end user device can be performed by rotating the face relative to the body to silence audio broadcast.

An electronic device including a body and a light source module is provided. The body has a side on which an unstable display is disposed and another side on which a bi-stable display is disposed. The light source module is arranged inside the body and configured to provide a light source to one or none of the unstable display and the bi-stable display.

A terminal device, including a screen, a first camera, and a movement mechanism, where the first camera is disposed on a movable component of the movement mechanism, the movement mechanism is disposed on the back of the screen, and the movable component is configured to drive the first camera to move from the back of the screen to a position at which the first camera can be seen from in front of the terminal device.
