Abstract
A display device includes: a display panel; a first frame to which a first end of the display panel is fixed; and a second frame connected to the first frame, wherein the second frame is moveable in a first direction or a second direction that is opposite to the first direction with respect to the first frame. A second end of the display panel is in a moveable floating state guided by the second frame. The area of an externally exposed surface of the display panel is widened when the second frame is moved in the first direction, and is narrowed when the second frame is moved in the second direction.
Claims18
A display device comprising:
- a display panel;
- a first frame to which a first end of the display panel is fixed and supporting a back surface of the display panel;
- and
- a second frame connected to the first frame, wherein the second frame is moveable with respect to the first frame using a linear motion in a first direction or a second direction that is opposite to the first direction,
- wherein a second end of the display panel is in a moveable floating state guided by the second frame such that the second end of the display panel is movable with respect to the second frame,
- wherein an area of an externally exposed surface of the display panel is widened when the second frame is moved in the first direction, and is narrowed when the second frame is moved in the second direction, and
- wherein when a touch having a predetermined pattern is input to the externally exposed surface of the display panel, the second frame is moved in the first direction from the first frame.
A display device comprising:
- a display panel;
- a first frame to which a first end of the display panel is fixed;
- a second frame connected to the first frame;
- and
- a proximity sensor configured to generate a proximity signal, wherein the second frame is moveable in a first direction or a second direction that is opposite to the first direction with respect to the first frame based at least in part on the proximity signal,
- wherein a second end of the display panel is in a moveable floating state guided by the second frame,
- wherein an area of an externally exposed surface of the display panel is widened when the second frame is moved in the first direction, and is narrowed when the second frame is moved in the second direction.
A method for operating a display device, the method comprising:
- inputting a predetermined pattern to an externally exposed surface of a display panel, wherein when the predetermined pattern is input to the display panel, a second frame is moved in a first direction from a first frame, and wherein the predetermined pattern includes touch inputs that occur in a predetermined sequence in a plurality of predetermined regions on the externally exposed surface;
- moving the second frame, which is connected to the first frame to which a first end of the display panel is fixed, in the first direction with respect to the first frame or in a second direction with respect to the first frame;
- and
- allowing a second end of the display panel, which is in a floating state, to be guided by the second frame, so that an area of the externally exposed surface is widened when the second frame is moved in the first direction and so that the display panel folds and the area of the externally exposed surface is narrowed when the second frame is moved in the second direction.
