An electronic device ( 1 ) provides for the selective illuminating of an associated display ( 5 ) thereby reducing battery power consumption. The electronic device ( 1 ) provides for detecting an event that will trigger an update of the display ( 5 ) and activation of illumination elements ( 27 ) for illuminating the display and determining whether the information to be displayed will occupy a region (B-L) of the display. If so, the region of the display is selectively illuminated by one or more of the illumination elements. The predetermined illumination time period may depend on a selected combination of a size of the region, a location of said region and/or a priority associated with the event.
