A display apparatus includes a display and a processor. The processor is configured to: based on a user command for displaying a UI being input, identify at least one from among a size of the display and a ratio of the display, determine a size of the UI and a layout of the UI to correspond to the at least one from among the scale and the ratio of the display, and control the display to display a plurality of UI elements in the UI, according to the size and the layout of the UI.

An image display apparatus includes: a housing; a display for displaying an image; a driving unit configured to change a size of a display area exposed to the outside of the housing among an entire area of the display; and a controller, wherein the controller determines whether an image displayed through at least a portion of the display area is a static image, when the size of the display area is smaller than the size of the entire area, determines whether the image is displayed for a certain time or longer, when the image is the static image, controls the driving unit to change the size of the display area, when the image is displayed for the certain time or longer, and controls the display so that the image is displayed in response to a degree of change in the size of the display area.

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.

A display terminal adjustment method is provided, this method includes: obtaining image data of an image to be displayed and screen data of the display terminal; obtaining a first adjustment ratio and a second adjustment ratio according to an image size in the image data and a screen size in the screen data; adjusting the image to be displayed to obtain a first target image according to the first adjustment ratio, and adjusting the image to be displayed to obtain a second target image according to the second adjustment ratio; and adjusting the display terminal to be in a target display mode according to the first target image and the second target image, according to this method, a size of a blank area of the display terminal is reduced, and an utilization rate of the screen of the display terminal is improved.

An electronic device includes a first display unit, a communication unit configured to communicate with an external device including a second display unit, and a control unit configured to rotate an image to be displayed on the first display unit, in accordance with a rotational angle in a plane parallel to a screen of the first display unit, and rotate an image to be output to the external device, in accordance with the rotational angle of the first display unit and a rotational angle in a plane parallel to a screen of the second display unit.

A flexible display device including a flexible display panel, and a panel driver configured to receive display data from a host processor, to store the display data, and to drive the flexible display panel based on the display data. While the flexible display panel is deformed, the panel driver drives the flexible display panel based on the display data stored before the flexible display panel is deformed to display an image having a size suitable for a current exposed region of the flexible display panel.

The disclosure provides a display apparatus and a cast method, including: a display; a rotation assembly; and a controller configured to receive image information sent from a terminal device. When the terminal is in a portrait mode, the image information includes effective area information and left and right black area information. The effective area information corresponds to content displayed on a current screen of the terminal device. The display is controlled to present a cast image based on the effective area information. The cast image is obtained by enlarging the effective area information by preset times.

A display device whose aspect ratio can be changed is provided. The display device includes a plurality of display units and a plurality of driver circuit units. The plurality of display units each include a light-emitting portion and a connection region. The plurality of driver circuit units each include a driver circuit portion and a connection region. The connection regions of the adjacent units overlap with each other and one shaft passes through the connection regions. The adjacent units are electrically connected to each other with the one shaft. With such a structure, an angle between the adjacent units electrically connected to each other with one shaft can be changed, which enables the aspect ratio of the display device to be changed.

An example apparatus includes a communication interface; memory; a screen to present media; and processor circuitry to at least: cause transmission of an indication related to a screen state to a source device, the screen state corresponding to at least one of an orientation capability or a rotation capability of the screen of a sink device; and access the media, the media from the source device, the media adapted based on the indication related to the screen state.

Provided is a display device and a method for controlling same. The display device of the present disclosure may include a display, a communication interface, a motor configured to rotate the display, and a processor configured to control the display to display an image content on the display disposed in a first orientation, display a user interface (UI) for rotating the image content and the display, receive a signal, from an external device through the communication interface while the UI is displayed, for rotating at least one of the image content or the display, and based on the received signal, rotate the image content displayed on the display or control the motor to rotate the display to a second orientation.
