In order to solve a problem that conventionally there is no image output apparatus in which a wide-band image can be output in a narrow band, an image output apparatus includes: an accepting unit that accepts first-image information, which is information related to a first image of a first band; and multiple image output units that output second images, each of which is an image of a second band that is narrower than or equal to the first band, using the first-image information, wherein a third image obtained as a result of output of the second images by the multiple image output units is an image of a third band that is wider than the first band. Accordingly, it is possible to provide an image output apparatus in which a wide-band image can be output in a narrow band.

A display device includes a display panel which displays an image, where a plurality of areas, in each of which a plurality of pixels is positioned, is defined in the display panel, and a controller which generates image data based on an image signal received from the outside and compensates for deterioration of the display panel. The controller includes a stress information generator which generates stress information of the display panel corresponding to the deterioration and a deterioration compensator which changes at least one selected from a spatial resolution and a bit-depth of each of the plurality of areas based on the stress information of each of the plurality of areas.

On a foveated electronic display, foveated image data may include a variety of groupings of pixels in different resolutions for different parts of the display. As such, different parts of the foveated image data are routed to different pixels of the electronic display. One way of routing data is to use multiplexers to select which image data is routed to which source latches of columns of pixels of the electronic display. Depending on the number of columns of the electronic display, however, the multiplexers may consume a significant portion of the die area while also consuming a significant amount of energy and reducing the field-of-view (FOV). Instead of using multiplexers to route foveated image data in the electronic display, groups of source latches of the electronic display may be hardwired to respective wires of a pixel data bus.

An electronic system may include a processor configured to output image data corresponding to an original image having a first resolution and a synchronization signal; and a display driving device configured to generate a result image having a higher than the first resolution, based on the image data and the synchronization signal, the image data including line image data corresponding to horizontal lines of the original image, and the synchronization signal including horizontal synchronization signals output at horizontal periods, the horizontal synchronization signals including active synchronization signals determining output timing of the line image data, and blank synchronization signals unrelated to the line image data, and the processor configured to output at least one of the blank synchronization signals between at least some of the active synchronization signals, based on scaling information determined based on the first resolution and the second resolution.

A display apparatus is disclosed. The display apparatus comprises: a display panel which can output a first resolution content at a first frame rate; a communication interface comprising communication circuitry; and a processor which when a first resolution content is received through the communication interface and the frame rate of the content is the first frame rate, is configured to: adjust the resolution of the received content to a second resolution, generate an interpolated frame for the second resolution content, and control the display panel to output the second resolution content including the interpolated frame at a second frame rate greater than the first frame rate.

A display device includes: a communication interface; a display; and a processor configured to: based on an image output device being communicably connected to the communication interface, acquire first device information of the image output device, based on a content provided from an external server being selected, control the communication interface to transmit the first device information and second device information of the display device to the external server, the second device information corresponding to the display device, receive the content from the external server through the communication interface, the content including a main screen image corresponding to the second device information, the content being associated with a sub screen image corresponding to the first device information, control the display to display the main screen image, and control the communication interface to transmit the sub screen image to the image output device such that the image output device outputs the sub screen image.

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.
