1. A display system, comprising:
a foldable display unit to display visual information in a display area, the visual information based at least in part on display data; and
a display control unit receiving the display data and at least one fold signal indicative of a fold in at least a portion of the display area, and outputting one or more display control signals operative to cause the display unit to display the visual information, the display control signals being output at least in part in response to the at least one fold signal to adapt the one or more display control signals to change an appearance of the visual information,
wherein the one or more display control signals to change the appearance avoids the display of the visual information on or near a fold axis in the folded display unit,
wherein the fold in the display unit creates a deformed area located within the display area, the deformed area located adjacent to the fold axis of the display unit;
wherein the display control unit outputs one or more display control signals to change the appearance of the visual information to compensate for impairment in the deformed area that is caused by the fold;
wherein the appearance of the visual information in or near the deformed area is changed from a first display format to a second display format, the second display format configured to provide a display of the same visual information provided in the first display format; and
wherein the second display format compensates for impairment of visual information displayed in or near the deformed area by providing an appearance of a continuous display of the visual information across the deformed area while maintaining a constant size of the continuous display of the visual information in the first display format and in the second display format.
