Abstract:
1. A method comprising: while a portable electronic device including a display is in a low-power condition in which no area of the display is illuminated and no information is displayed on the display, detecting, by the portable electronic device, a gesture that begins at a first end of the display and progresses toward a second end, opposite the first end of the display; in response to detecting the gesture, progressively illuminating the display, from a state in which the display is not illuminated, by gradually increasing a size of an illuminated area of the display from the first end of the display, at which the gesture began, toward the second end of the display opposite the first end as the gesture continues, wherein the gesture controls the size of the illuminated area; wherein the illuminated area extends a full width of the display, between opposite sides of the display at the first end of the display at which the gesture began and between a current touch location and the first end; wherein the illuminated area is not illuminated immediately prior to detecting the gesture; in response to detecting discontinuation of the gesture after meeting a predetermined period of time or a predetermined distance, illuminating the entire display; and in response to detecting discontinuation of the gesture prior to meeting the predetermined period of time or the predetermined distance, discontinuing progressively illuminating the display and returning to the low-power condition in which no area of the display is illuminated.
