Abstract
A display device includes a flexible display module and provides a display area including a fingerprint recognition area, and a non-display area outside the display area. The flexible display module includes a display panel including a light-emitting element, a touch sensing unit disposed on the display panel, and a fingerprint recognition unit overlapping with the fingerprint recognition area. The touch sensing unit is configured to sense pressure applied to the flexible display module in an in-folding mode in which the flexible display module is folded such that a portion of the display area faces another portion of the display area.
Claims20
A display device comprising:
- a flexible display module comprising a display surface,
- wherein the display device provides:
- a display area comprising a fingerprint recognition area;
- and
- a non-display area outside the display area,
- wherein the flexible display module comprises:
- a display panel comprising a light-emitting element configured to display an image in the display area via the display surface;
- a touch sensing unit disposed on the display panel;
- and
- a fingerprint recognition unit overlapping the fingerprint recognition area, and
- wherein the touch sensing unit is configured to sense a magnitude of pressure applied to the flexible display module in an in-folding mode in which the flexible display module is fully folded such that a portion of the display surface faces, in a direction normal to the display surface, another portion of the display surface, the magnitude of pressure being determined based on a change in distance in the direction normal to the display surface between a touch sensing electrode of the touch sensing unit disposed on the portion of the display surface and another touch sensing electrode of the touch sensing unit disposed on the another portion of the display surface.
A display device comprising:
- a flexible display module comprising a display surface;
- and
- a force sensor,
- wherein the display device provides:
- a display area comprising a fingerprint recognition area;
- and
- a non-display area outside the display area,
- wherein the flexible display module comprises:
- a display panel comprising a light-emitting element disposed between an uppermost surface of the display panel and a lowermost surface of the display panel;
- a touch sensing unit disposed on the display panel;
- and
- a fingerprint recognition unit overlapping with the fingerprint recognition area,
- wherein, in an unfolded state of the flexible display module, each of the uppermost surface and the lowermost surface of the display panel is disposed between the touch sensing unit and the force sensor, and
- wherein the force sensor is configured to sense pressure applied to the flexible display module in an out-folding mode in which the flexible display module is fully folded such that a portion of the display area faces an opposite direction from another portion of the display area.
A display device comprising:
- a flexible display module,
- wherein the display device provides:
- a display area via the flexible display module, the display area comprising a fingerprint recognition area;
- and
- a non-display area outside the display area,
- wherein the flexible display module comprises:
- a display panel comprising a light-emitting element in the display area;
- a touch sensing unit disposed on the display panel;
- and
- a fingerprint recognition unit overlapping with the fingerprint recognition area, and
- wherein the touch sensing unit is configured to sense a capacitance between a portion of the display area and another portion of the display area in an in-folding mode in which the flexible display module is fully folded such that the portion of the display area overlaps and faces the another portion of the display area with the portion of the display area being in a different plane than the another portion of the display area.
