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.

Flexible display device and method for driving the same

A display device includes: a frame that includes a plurality of protrusions; a display panel disposed on the frame that includes a planar portion and a curved portion; a pressure sensing unit disposed between the frame and the display panel that overlaps the curved portion and that includes a plurality of first electrodes and a plurality of second electrodes disposed in a different layer; and a pressure sensing drive unit connected to the plurality of first electrodes and the plurality of second electrodes. Any one of the plurality of second electrodes at least partially overlaps any one of the plurality of first electrodes. At least one of the plurality of protrusions overlaps a region where one of the plurality of first electrodes and one of the plurality of second electrodes overlap each other.

Display device

A display device includes a folding area and a non-folding area, a display panel including a plurality of pixels, and a digitizer arranged at one side of the display panel and including a plurality of loop coils, where, when a hovering event of an input unit is detected in the folding area, the digitizer increases an alternating current signal applied to at least one loop coil of the plurality of loop coils arranged in the folding area, and calculates a hovering height of the input unit based on a change in a magnetic field between the input unit and loop coils of the plurality of loop coils, the loop coils including a loop coil overlapping the input unit and adjacent loop coils around the input unit.

A display device including a bottom cover, a window disposed on the bottom cover, a frame disposed between the bottom cover and the window, a display panel disposed between the frame and the window, a bracket disposed between the display panel and the frame, and a pressure sensing portion disposed between the bracket and the display panel, in which the frame includes a base portion disposed between the bottom cover and the bracket, a first support portion protruding from an edge of the base portion toward an edge of the window, and a second support portion protruding from the first support portion, disposed between an edge of the bracket and the base portion, and spaced apart from the base portion.

A flexible display device includes a flexible display panel, a touch panel to detect a touch input, a haptic panel to produce a tactile sensation, a haptic driver to control the haptic panel, and a curvature detector to detect a curvature of the display panel. The haptic driver controls a haptic signal corresponding to an output of the curvature detector.
