Abstract: A flexible display device includes a bendable touch display panel, a touch detector, a screen divider, and a panel driver. The touch display panel includes at least one touch sensor. The touch detector detects 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 at least one touch sensor. The screen divider divides a display area of the touch display panel into a plurality of divided areas with respect to the curved portion, and defines the divided areas as a display divided area and a non-display divided area, respectively, based on the touch information. The panel driver activates at least a portion of the display divided area and deactivate the non-display divided area.

Abstract: A display apparatus and driving method are provided. The display apparatus, which operates in a display mode or a sensing mode, includes: a first signal line configured to apply a first driving signal to a pixel circuit during the display mode and to apply a sensing input signal to the pixel circuit during the sensing mode; a second signal line configured to apply a second driving signal to the pixel circuit during the display mode and to transfer a sensing output signal from the pixel circuit during the sensing mode; and a pixel including the pixel circuit, wherein a first current path for image display is formed in the pixel circuit during the display mode, and a second current path, configured to measure a resistance of a pressure resistance layer between the first signal line and the second signal line, is formed in the pixel circuit during the sensing mode.
