Abstract

A dynamically flexible article or device, such as a wristband, an armband, a rollable e-reader, or a belt, includes a flexible electronic component (e.g., a flexible display) and a support structure coupled to the flexible electronic component. The support structure is configured to limit bending of the flexible electronic component to a range within a bending tolerance of the flexible electronic component.

Claims

1. An article, comprising:

a flexible electronic component; and

a flexible support structure at least partially slidably coupled to the flexible electronic component, the flexible support structure and the flexible electronic component being slidable relative to one another when the article is moved between a substantially flat position and a curved position, such that the article can have a bending range that is within a bending range of the flexible electronic component itself and complies with bending range requirements of the article,

wherein the flexible support structure includes a first flexible support structure portion made of a first material and a second flexible support structure portion made of a second material which is more flexible than the first material, wherein the second flexible support structure portion defines a cavity and a slot which is spatially separate from the cavity along the cavity, the first flexible support structure portion being disposed in the slot and the flexible electronic component being disposed in the cavity.

2. The article of claim 1, wherein the flexible support structure is bendable at multiple positions along its length.

3. The article of claim 1, wherein the flexible electronic component is not fixedly attached to the flexible support structure at any position.

4. The article of claim 1, wherein the second flexible support structure portion includes a portion having a bottom wall and a pair of opposing sidewalls extending upward from the bottom wall, and wherein the cavity is defined between the bottom wall and the pair of opposing sidewalls.

5. The article of claim 4, further comprising a flexible sheet coupled to the flexible support structure and at least partially covering the cavity, the flexible electronic component being at least partially visible through the flexible sheet, and the flexible sheet configured to retain the flexible electronic component within the cavity of the second flexible support structure.

6. The article of claim 1, wherein the flexible electronic component is fixedly attached to the flexible support structure at at least one point.

7. The article of claim 6, wherein the flexible electronic component is fixedly attached to the second flexible support structure portion via a spring element, the spring element configured to apply tension to at least one end of the flexible electronic component.

8. The article of claim 1, wherein the slot is formed proximate to the cavity, such that the second flexible support structure portion provides support to the flexible electronic component disposed in the cavity.

9. The article of claim 1, wherein the flexible electronic component and the first flexible support structure portion are slidable relative to one another.

10. The article of claim 1, wherein the second flexible support structure portion comprises a bellowed wall disposed radially inward of the flexible electronic component and the first flexible support structure portion.

11. The article of claim 10, wherein the bellowed wall comprises a plurality of roots and a plurality of crests disposed therebetween, the plurality of roots being fixedly attached to corresponding portions of the first flexible support structure portion, the crests of the bellowed wall being allowed to move between the fixedly attached roots.

12. The article of claim 10, wherein the first flexible support structure portion comprises a plurality of rigid links pivotally connected to one another.

13. The article of claim 12, wherein a subset of the plurality of links are slidably connected to one another via a plurality of pins disposed in a plurality of slots, the subset of links configured to slide away from one another when the article is moved from a bent position to a substantially flat position, thereby increasing a length of the first flexible support structure portion.

14. The article of claim 1, wherein the first and second flexible support portions define a pair of pockets each configured to slidably receive a portion of the flexible electronic component, thereby facilitating a controlled movement of the article.

15. The article of claim 1, wherein the second flexible support structure portion has a first end and a second end opposite the first end, the slot being formed between and spaced from the first and second end.
