Flexible display device and method for driving the same

A flexible display device, comprising:

• a touch display panel comprising a plurality of touch sensors;
• a detector to detect a curved portion of the touch display panel and touch information corresponding to a touch applied to the touch display panel based on a sensing result from the plurality of touch sensors;
• a screen divider to divide a display area of the touch display panel into a plurality of divided areas with respect to the curved portion and to define the divided areas as a display divided area and a non-display divided area, respectively, based on the touch information;
• and
• a panel driver to control the display divided area and the non-display divided area,
• wherein:
• the panel driver is to display an image on at least a portion of the display divided area and not to display an image on the non-display divided area,
• the panel driver is to drive at least one touch sensor in the display divided area from among the plurality of touch sensors and to stop a driving operation of at least one touch sensor in the non-display divided area from among the plurality of touch sensors,
• in response to the sensing result from the plurality of touch sensors having a value in a first range, the detector is to detect the touch information based on the sensing result, and
• in response to the sensing result from the plurality of touch sensors having a value in a second range, the detector is to detect the curved portion based on the sensing result.
