Abstract

A display device for a vehicle includes a first frame configured to be coupled to a dashboard of the vehicle, a second frame configured to move vertically relative to the first frame, and a flexible display having a first area that extends along the second frame and defines a flat surface and a second area that is configured to extend from the first area, where the display device is configured to vary a shape of the second area. The display device further includes a first roller that extends in an upward-downward direction and that supports an inner surface of the flexible display to allow the second area to be curved around the first roller, a first moving body is coupled to the second area, and a second actuator configured to move the first roller and the first moving body laterally relative to the second frame.

First claim

What is claimed is:

1. A display device for a vehicle, comprising:
a first frame configured to be coupled to a dashboard of the vehicle, at least a portion of the first frame being configured to be coupled to an inside of the dashboard;
a second frame configured to move vertically relative to the first frame;
a first actuator configured to move the second frame upward and downward relative to the first frame to thereby change an area of the second frame that is exposed to an outside of the dashboard;
a flexible display comprising:
a first area that extends along the second frame and defines a flat surface, and
a second area that is configured to extend from the first area, wherein the display device is configured to vary a shape of the second area;

a first roller that extends in an upward-downward direction and that supports an inner surface of the flexible display to allow the second area to be curved around the first roller;
a first moving body that extends in the upward-downward direction and is coupled to an end portion of the second area; and
a second actuator configured to move the first roller and the first moving body laterally in a leftward-rightward direction relative to the second frame.

2. The display device of claim 1 , wherein the first actuator comprises:
a first screw shaft that extends in the upward-downward direction and is rotatably coupled to the first frame, the first screw shaft comprising a first thread disposed at an outer circumferential surface of the first screw shaft;
a first slider coupled to the second frame and engaged with the first thread of the first screw shaft; and
a first motor configured to rotate the first screw shaft to thereby move the first slider along the first screw shaft.

3. The display device of claim 2 , wherein the first actuator further comprises:
a second screw shaft that extends in parallel to the first screw shaft and is rotatably coupled to the first frame, the second screw shaft comprising a second thread disposed at an outer circumferential surface of the second screw shaft;
a second slider coupled to the second frame and engaged with the second thread of the second screw shaft; and
an interlocking belt that connects the first screw shaft and the second screw shaft to each other and is configured to rotate the second screw shaft together with the first screw shaft.

4. The display device of claim 3 , wherein the first screw shaft and the second screw shaft have shapes identical to each other or symmetric to each other with respect to a reference line, and
wherein the first slider and the second slider have shapes identical to each other or symmetric to each other with respect to the reference line.

5. The display device of claim 3 , further comprising a third frame configured to move together with the first roller in the leftward-rightward direction, at least a portion of the third frame overlapping with the second frame,
wherein the first moving body is coupled to the third frame and configured to move relative to the third frame in the leftward-rightward direction.

6. The display device of claim 5 , wherein the second actuator comprises:
a third screw shaft that extends in the leftward-rightward direction and is rotatably coupled to the third frame, the third screw shaft comprising a third thread disposed at an outer circumferential surface of the third screw shaft;
a fourth screw shaft that extends in parallel to the third screw shaft and is rotatably coupled to the third frame, the fourth screw shaft comprising a fourth thread disposed at an outer circumferential surface of the fourth screw shaft;
a third slider coupled to the second frame and engaged with the third thread of the third screw shaft;
a fourth slider coupled to the first moving body and engaged with the fourth thread of the fourth screw shaft; and
a second motor configured to rotate the third screw shaft and the fourth screw shaft.

7. The display device of claim 6 , wherein the second actuator is configured to move the first roller relative to the second frame by a first distance, and to move the first moving body relative to the second frame by a second distance that is twice the first distance.

8. The display device of claim 5 , wherein the third frame comprises:
a first upper beam disposed at an upper end of the first moving body and configured to guide the first moving body to slide in the leftward-rightward direction; and
a first lower beam disposed a lower end of the first moving body and configured to guide the first moving body to slide in the leftward-rightward direction, and
wherein the first roller comprises an upper end rotatably coupled to the first upper beam, and a lower end rotatably coupled to the first lower beam.

9. The display device of claim 8 , wherein the first roller is coupled to the third frame and configured to move in the leftward-rightward direction, and
wherein the display device further comprises a first elastic body configured to support the first roller and to apply force to the first roller in a direction away from the second frame.

10. The display device of claim 1 , wherein the flexible display further comprises a third area that extends from the first area and is spaced apart from the second area in the leftward-rightward direction, wherein the display device is configured to vary a shape of the third area, and
wherein the display device further comprises:
a second roller that extends in the upward-downward direction and is configured to support the inner surface of the flexible display to allow the third area to be curved around the second roller,
a second moving body that extends in the upward-downward direction and is coupled to an end portion of the third area, and
a third actuator configured to move the second roller and the second moving body in the leftward-rightward direction relative to the second frame.

11. The display device of claim 10 , wherein the first roller and the second roller are configured to, based on a simultaneous operation of the second actuator and the third actuator, move in opposite directions from each other along the leftward-rightward direction, and
wherein the first moving body and the second moving body are configured to, based on the simultaneous operation of the second actuator and the third actuator, move in opposite directions from each other along the leftward-rightward direction.

12. The display device of claim 10 , further comprising:
a third frame coupled to the first moving body and configured to move together with the first roller in the leftward-rightward direction, at least a portion of the third frame overlapping with the second frame; and
a fourth frame coupled to the second moving body and configured to move together with the second roller in the leftward-rightward direction, at least a portion of the fourth frame overlapping with the second frame,
wherein the first moving body is configured to move in the leftward-rightward direction relative to the third frame, and
wherein the second moving body is configured to move in the leftward-rightward direction relative to the fourth frame.

13. The display device of claim 12 , wherein the second actuator comprises:
a third screw shaft that extends in the leftward-rightward direction and is rotatably coupled to the third frame, the third screw shaft comprising a third thread disposed at an outer circumferential surface of the third screw shaft;
a fourth screw shaft that extends in parallel to the third screw shaft and is rotatably coupled to the third frame, the fourth screw shaft comprising a fourth thread disposed at an outer circumferential surface of t
