According to an example embodiment of the present disclosure, an electronic device includes a display that is flexible, has at least a portion located at a first side of the electronic device, and is changeable in size to which the display is exposed to the first side, and a controller configured to display first content in at least a portion of the first side. In response to a first input, the controller displays a first portion of the first content in a first area of the first side and displays a second area distinguished from the first area.

Systems, methods, and non-transitory computer readable media for controlling perspective in an extended reality environment are disclosed. In one embodiment, a non-transitory computer readable medium contains instructions to cause a processor to perform the steps of: outputting for presentation via a wearable extended reality appliance (WER-appliance), first display signals reflective of a first perspective of a scene; receiving first input signals caused by a first multi-finger interaction with the touch sensor; in response, outputting for presentation via the WER-appliance second display signals to modify the first perspective of the scene, causing a second perspective of the scene to be presented via the WER-appliance; receiving second input signals caused by a second multi-finger interaction with the touch sensor; and in response, outputting for presentation via the WER-appliance third display signals to modify the second perspective of the scene, causing a third perspective of the scene to be presented via the WER-appliance.

A display apparatus including a housing; a display; a roller accommodated in the housing to rotate and roll or unroll the display; and a processor configured to in response to receiving a command to display content, control the roller to rotate and unroll the display from the housing so the display is drawn out and extended from the housing, and control the display to display an entire image of the content while simultaneously expanding a size of the entire image of the content as the display is being extended from the housing so a partial portion of the content is not blocked from being viewed as the display is drawn out and extended from the housing.

According to an example embodiment, an electronic device outputs, on a second display screen, a page layout output on a first display screen along with another page layout grouped together with the page layout in response to a screen switch from the first display screen to the second display screen having a greater display area than a display area of the first display screen, and switches the grouped page layouts in response to a swipe input being detected.

The present application discloses a signal channel switching method, a display terminal and a computer-readable storage medium. The signal channel switching method includes the following operations: establishing a data connection with a first external device connected with a first hot plug pin; obtaining a first voltage detected by a second hot plug pin, and judging whether the first voltage conforms to a preset rule; if the first voltage conforms to the preset rule, obtaining information of a second external device connected with the second hot plug pin; cutting off the data connection with the first external device and establishing a data connection with the second external device according to the information of the second external device.

An image processing method applied to a display device having a processing circuit and a screen and includes: receiving a first image from one of a plurality of electronic devices; detecting whether the first image has a black border area; and if the first image has the black border area, performing a first display operation, wherein performing the first display operation includes: removing the black border area of the first image, to generate a second image; adjusting the size of the second image according to the size of a display area of the screen; calculating a first blank area of the screen based on the adjusted second image; requesting a third image from another one of the electronic devices according to the size of the first blank area; and filling the display area of the screen with the adjusted second image and the third image.

In this display method, an information processing apparatus converts, for each of plural display surfaces that are parts of an entire screen, a position and size of a window in a coordinate system of the entire screen into a position and size of the window in a coordinate system of the display surface according to arrangement of the plural display surfaces, and transmits, for each of the plural display surfaces, the position and the size of the window in the coordinate system of the display surface to a display control apparatus that has a display device that provides the display surface. And each of plural display control apparatuses receives contents data from a terminal, and displays an image rendered based on the received contents data according the received position and size of the window in the coordinate system of a display surface of the display control apparatus.

An example disclosed herein determines a setting to present a presentation on a transparent display layer of a display, adjusts a transparency of a first adjustable transparency layer of the display based on the first setting to present the presentation through the first adjustable transparency layer, and adjusts a transparency of a second adjustable transparency layer of the display based on the first setting to prevent the presentation from being presented through the second adjustable transparency layer.

A video signal conversion method, a corresponding video signal conversion device and a display system including the video signal conversion device, by which low-resolution video signals can be converted and combined into a high-resolution video signal, such that a high-resolution image combined by low-resolution images can be displayed on an ultra-high definition display screen. The video signal conversion method includes: receiving in parallel a plurality of sub-frames divided from a low-resolution image of a video signal; performing image processing on each of the received sub-frames; and synthesizing the plurality of sub-frames after being subjected to the image processing into a high-resolution image frame and displaying the high-resolution image on a display device.

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.
