A display device has a plurality of display panels () together forming a single display screen, where each display panel () is connected to a display controller () which receives display data of a portion of a complete image for display on the display panel (). The complete image (S) includes one or more bounded regions (S, S, S, S) of display data. Each display controller () also receives position information relating to a change in lateral position and/or stacking order position of one or more bounded regions that are to be displayed at least partly on that display panel (). If the display controller () determines that it does not have knowledge of display data in the bounded region (S, S, S, S) to be displayed on the display panel for which the position information was received, it obtains that knowledge from another display controller () that has such knowledge. The display controller () then processes the display data for the portion of the complete image utilising the knowledge obtained from another display controller (), and outputs the processed display data for the portion of the complete image to the corresponding display panel ().

A display device has display panels forming a single display screen, where each display panel is connected to a display controller which receives display data of a portion of a complete image for display on the display panel. The complete image includes one or more bounded regions of display data. Each display controller receives position information relating to a change in lateral position and/or stacking order position of one or more bounded regions to be displayed at least partly on that display panel. If the display controller does not have knowledge of display data in the bounded region to be displayed on the display panel, it obtains that knowledge from another display controller. The display controller processes the display data for the portion of the complete image utilizing the knowledge obtained, and outputs the processed display data for the portion of the complete image to the corresponding display panel.

A display control device for outputting display data to frame buffers includes an input for receiving portions of the display data, different portions being in raw form and in compressed form. A data controller determines, for each received portion, whether it is in compressed form or raw form and controls the received portion to move along a first, bypass, path if it is determined that the received portion of display data is in raw form and to control the received portion of display data to move along a second path to a decompression engine if it is determined that the received portion of display data is in compressed form. The decompression engine decompresses the particular portion of compressed display data and forwards a corresponding portion of decompressed display data along a third path, the portions of data from the first and third paths then being output to the frame buffers.

Method of processing display data

Data, particularly display data, is sent to a particular peripheral device, particularly a display device) from a computer device, such as a mobile device. The method involves determining an identifier of each peripheral device and receiving () a user identification identifying a particular peripheral device. The user identification is then associated () with the identifier of the particular peripheral device, and data is sent to the particular peripheral device based on the identifier associated with the user identification. The user identification comprises a user gesture which is captured as an input image, which is processed to determine which particular peripheral device the user gesture is gesturing towards and associating the user gesture with the identifier of the particular peripheral device. Alternatively the user identification may be directly input by a user on a display showing either recognised elements that have been associated with identifiers of the peripheral devices, or a listing of available peripheral devices.
