A display device comprising: a display panel to display a frame having a resolution up to a first frame rate; a plurality of image processing units; and a processor. The processor configured to, based on change from a first mode of displaying a content, among a plurality of modes of the display device, to a second mode of displaying plural contents, change frame rates of a plurality of contents output from the plurality of image processing units to a same frame rate, mix the plurality of contents with the frame rates changed to the same frame rate, and change a vertical resolution of the mixed content. The display panel is enabled to output the mixed content, at a second frame rate greater than the first frame rate.

Methods, systems and devices for displaying video content on large, high resolution video walls, which may comprise a mesh network of an array of display tiles with redundant network switching, in which a virtual, unlimited pixel canvas is created in a video controller memory to facilitate packetizing and addressing of video content packets for delivery to the video wall through a packet-switched network. Embodiments disclosed are particularly well-suited for use with video walls employing LED tiles.

A method for operating as electronic apparatus includes displaying, by a display apparatus, a first image based on first image data transmitted from a first terminal apparatus to the electronic apparatus in a first area of a display surface and changing, by the first terminal apparatus the amount of the first image data transmitted by the first terminal apparatus per unit time period to the electronic apparatus in accordance with a change instruction to change the size of the first area.

In an embodiment according to the present disclosure, disclosed is an electronic device including a display, a first housing, a second housing at least partially overlapping and being movable with respect to the first housing, a first conductive region formed or disposed inside the first housing, and a second conductive region formed or disposed inside the second housing so as to at least partially overlap with the first conductive region when the first housing is moved with respect to the first housing, a display in which at least the first region is exposed to the outside of an electronic device through a front surface of the electronic device, and at least one processor in which, when the electronic device is switched from the first state to the second state, a second region extending from the first region of the display is withdrawn from the inside of the first housing and exposed to the outside of the electronic device along with the first region and, when the electronic device is switched from the second state to the first state, is introduced into the inside of the first housing and operatively connected to the display. The at least one processor identifies a capacitance value, based on an overlapped region of the first conductive region and the second conductive region, and determines an externally exposed region of the display, based on the identified capacitance value, and controls the region determined to be exposed outside, to an activated state, and controls the remaining region except the region determined to be exposed outside, to an inactivated state. In addition to this, various embodiments identified through the specification are possible.

An electronic display system includes a display controller configured to receive a first hinge angle between a first display and a second display pivotally coupled to the first display via a hinge. A first portion of the rendered visual content is displayed on the first display and a second portion of the rendered visual content is displayed on the second display, the first portion and the second portion having rendered sizes based at least in part on the first hinge angle.

A method of controlling a display device may comprise: identifying a first area among all areas of a content displayable on a display; and scanning multiple pixel lines by multiple pixel lines in the first area and scanning one pixel line by one pixel line in a second area among all the areas of content which remain after excluding the first area, wherein at least one of a size and a position of the first area and a number of first areas is variable.

An image processing method performed by image processing device having an operating system includes receiving, by an image processing module of the operating system, an instruction of a first application program to call the image processing module of the operating system, where the instruction carries a to-be-displayed image and a resolution of the to-be-displayed image. The image processing method further includes when the resolution of the to-be-displayed image is less than a first threshold, performing, by the image processing module, super-resolution processing on the to-be-displayed image, and displaying an image obtained after the super-resolution processing.

An electronic device according to various embodiments may include a display panel, a Display Driving Integrated Circuit (DDIC) operatively coupled to the display panel, and a processor operatively coupled to the DDIC. The DDIC may be configured to receive, from the processor, a signal indicating that a first resolution is to be converted to a second resolution while displaying an image at the first resolution through the display panel, based on a horizontal synchronization signal including a first porch interval, change a length of the porch interval in response to the reception, and display the image at the second resolution through the display panel, based on the horizontal synchronization signal including the porch interval having the changed length.

A system for reducing bandwidth and/or reducing power consumed by a display may comprise a display having a background plane and a region of interest plane that may be identified by a gaze tracker. The region of interest may be of a higher quality picture. In some embodiments, the display may be a large panel display and in others a head mounted display (HMD).

Passive display devices such as a passive magnifying device (e.g., a screen magnifier) or a projector (e.g., a built-in mobile phone projector) are useful in enlarging photos, documents, videos, etc. for view for small-sized small-screen device screens. However, optimal content resolution for the small-screen device screens may not be optimal for the passive display devices. Particularly, when a small-screen device receives content from a remote computing device, the initial content resolution may not be optimal even for the small-screen device screen because of low transmission speed and/or low bandwidth of a connection with an original data source. Content resolution adjustment may be performed by determining distance between the passive display device and the small-screen device, calculating magnification ratio for the passive display device, and adjusting the content resolution based on the calculated magnification ratio.
