Abstract:
1. A method of controlling a flexible display device, comprising: obtaining from a display unit to which users' touches are input for the flexible display device having a display area presenting variable visual images for the flexible display device, a first input signal, a second input signal, a third input signal, and a fourth input signal input to the display unit by a user's touch and respectively corresponding to a first line element, a second line element, a third line element, and a fourth line element, each of the first through fourth line elements connected between a first edge portion and a second edge portion spaced-apart from the first edge portion of the display unit; making a determination of whether the first through fourth input signals are for controlling the display area by using a time when the first through fourth input signals are input or by using a similarity of gradients of the first through fourth line elements; and setting the display area based on a closed loop comprised of the first through fourth line elements and the first and second edge portions of the display unit, when the determination indicates that the first through fourth input signals are for controlling the display area.
