Abstract

A support for a flexible display of a portable electronic device includes: a first hinge element coupled to a second hinge element in a side-by-side arrangement, the first hinge element having: a display-receiving surface extending at least partway along a length of the first hinge element, the display-receiving surface for coupling to the flexible display; and a guide coupling the first hinge element to the second hinge element and guiding movement of the second hinge element relative to the first hinge element along a path between a first stop and a second stop, the first stop for limiting movement in a first direction and the second stop for limiting movement in a second direction; a neutral plane associated with movement of the first hinge element relative to the second hinge element is external to the support and located adjacent to the display-receiving surface.

Claims

1. A support for a flexible display of a portable electronic device, the support comprising:

a first hinge element coupled to a second hinge element in a side-by-side arrangement, the first hinge element comprising;

a display-receiving surface extending at least partway along a length of the first hinge element, the display-receiving surface for coupling to the flexible display; and

a guide coupling the first hinge element to the second hinge element and guiding movement of the second hinge element relative to the first hinge element along a path between a first stop and a second stop, the first stop for limiting movement in a first direction and the second stop for limiting movement in a second direction;

wherein a neutral plane associated with movement of the first hinge element relative to the second hinge element is external to the support and located adjacent to the display-receiving surface.

2. A support as claimed in claim 1, wherein the guide comprises a hook-shaped projection extending from a top of a first side of the first hinge element, the hook-shaped projection being received through a cutout of the second hinge element, and a curved projection extending from a bottom of the first side of the first hinge element, the curved projection abutting a groove in the second hinge element.

3. A support as claimed in claim 2, wherein the first stop extends from the hook-shaped projection to selectively abut a surface of the second hinge element when the hook-shaped projection is received through the cutout of the second hinge element.

4. A support as claimed in claim 3, wherein the second stop comprises at least a portion of the curved projection, the surface abutting a surface of the recess.

5. A support as claimed in claim 1, wherein the neutral plane is spaced from the display-receiving surface.

6. A support as claimed in claim 1, wherein the neutral plane extends through the flexible display.

7. A support as claimed in claim 1, wherein the neutral plane is spaced from the display-receiving surface for extending generally midway through a thickness of the flexible display.

8. A support as claimed in claim 2, wherein the path is defined by a concave surface of the hook-shaped projection and a convex surface of the curved projection.

9. A support as claimed in claim 1, wherein the second hinge element and the first hinge element are the same and offset from one another when assembled.

10. A support as claimed in claim 1, comprising multiple first hinge elements and multiple second hinge elements arranged side-by-side in a hinge assembly.

11. A support as claimed in claim 10, wherein the multiple second hinge elements comprise display-receiving surfaces for coupling to the flexible display of the portable electronic device.

12. A support as claimed in claim 10, wherein the hinge assembly is movable in the first direction and in the second direction from a starting position in which the hinge assembly is generally flat.

13. A support as claimed in claim 1, wherein the flexible display is a flexible touch-sensitive display.

14. A support for a flexible display of a portable electronic device, the support comprising:

a hinge assembly comprising a plurality of hinge elements, each hinge element comprising;

a display-receiving surface; and

a guide extending from a surface adjacent a bottom surface, the guide coupling the hinge element to an adjacent hinge element and guiding movement of the adjacent hinge element relative to the hinge element along a path between a first stop and a second stop, the first stop for limiting movement in a first direction and the second stop for limiting movement in a second direction;

wherein the display-receiving surface of the hinge element is maintained at a constant distance from a bottom surface of the adjacent hinge element when the hinge element moves along the path between the first stop and the second stop.

15. A support as claimed in claim 14, wherein a neutral plane associated with movement of the hinge element relative to the adjacent hinge element is external to the support and is spaced from the screen-receiving surface.

16. A support as claimed in claim 14, wherein the display-receiving surface is for coupling to the flexible display.

17. A support as claimed in claim 14, wherein the hinge assembly is movable in the first direction and in the second direction from a starting position in which the hinge assembly is generally flat.

18. A support as claimed in claim 14, wherein the flexible display is a flexible touch-sensitive display.

19. A support as claimed in claim 14, wherein the bottom surface is for coupling to the flexible display.

20. A hinge assembly for supporting a flexible membrane, the hinge assembly having a length and a width and being foldable along the width, the hinge assembly comprising:

a plurality of hinge elements coupled to one another in a side-by-side arrangement across the width; and

display-receiving surfaces located on a display-receiving side of the hinge assembly, the display-receiving surfaces for coupling to the flexible display;

wherein a length of the display-receiving side of the hinge assembly is constant during folding of the hinge assembly from a starting position in which the hinge assembly is generally flat toward a first position in which the display-receiving surfaces oppose one another and toward a second position in which the display-receiving surfaces face one another.

21. A hinge assembly as claimed in claim 20, wherein the flexible membrane is a flexible display.

22. A support for a flexible display of a portable electronic device, the support comprising:

hinge elements;

means for coupling the flexible display to the hinge elements;

means for coupling the hinge elements to one another, the hinge elements being movable relative to one another from a starting position in which the flexible display is generally flat; and

means for limiting movement of the hinge elements relative to adjacent hinge elements to maintain a constant distance between locations at which the flexible display is coupled to the hinge elements and locations at which the flexible display is coupled to the adjacent hinge elements when the hinge elements move relative to one another.

23. A support for a flexible display of a portable electronic device, the support comprising:

hinge elements;

means for coupling the flexible display to the hinge elements;

means for coupling the hinge elements to one another, the hinge elements being movable relative to one another from a starting position in which the display is generally flat; and

means for controlling a bend radius of the flexible display when the hinge elements move relative to one another.
