A dynamically flexible article or device, such as an armband, includes a flexible electronic component, such as a flexible electronic display, and a flexible support structure coupled to the flexible electronic component, wherein the flexible support and the flexible electronic component are flexible along two dimensions to thereby be able to conform to a complex curved surface. The flexible support includes bending limiting structure that constrains bending of the flexible electronic component to prevent undesirable bending.

1. An article, comprising: a flexible electronic component configured for bending along a first dimension and along a second dimension different from the first dimension; anda flexible support coupled to the flexible electronic component, the flexible support including bending limiting structure configured to constrain bending of the flexible electronic component along the first and second dimensions to a range within a bending tolerance of the flexible electronic component,wherein the flexible electronic component is slidable relative to at least a portion of the flexible support when the article is bent along the first dimension and when the article is bent along the second dimension, such that the article can have a bending range that is within a bending range of the flexible electronic component. 2. The article of claim 1, wherein the bending limiting structure comprises a first substrate and a second substrate movably coupled to the first substrate, a plurality of apertures formed in the first substrate, and a plurality of protrusions coupled to the second substrate and movably disposed within the plurality of apertures, respectively. 3. The article of claim 2, wherein each aperture of the plurality of apertures has a circular shape arranged to constrain movement of a respective one of the protrusions movably disposed therein. 4. The article of claim 2, wherein each aperture of the plurality of apertures comprises a slot, each of the slots defining a plurality of stop surfaces arranged to constrain movement of a respective one of the protrusions movably disposed therein. 5. The article of claim 1, wherein a portion of the first substrate is locally fixedly attached to a portion of the second substrate at a fixation point. 6. The article of claim 1, wherein the flexible support comprises a plurality of defined bending regions. 7. The article of claim 6, wherein the flexible support comprises at least one rigid zone disposed between two or more of the defined bending regions. 8. The article of claim 6, wherein the defined bending regions are angled relative to one another. 9. An article, comprising: a flexible electronic component configured for bending along a first dimension and along a second dimension different from the first dimension; anda flexible support configured for bending along the first dimension and along the second dimension, the flexible support slidably coupled to the flexible electronic component, the flexible support and the flexible electronic component being slidable relative to one another when the article is bent along the first dimension and when the article is bent along the second dimension, such that the article can have a bending range that is within a bending range of the flexible electronic component itself. 10. The article of claim 9, wherein the flexible electronic component has a first surface defining a display area and a second surface, opposite the first surface, disposed on a portion of the flexible support, and wherein the display area is substantially entirely viewable when the flexible electronic component is in a substantially flat position and when the flexible electronic component is bent along the first dimension and/or along the second dimension. 11. The article of claim 9, wherein prior to being coupled to the flexible support, the flexible electronic component has a neutral plane, and wherein the flexible support, when slidably coupled to the flexible electronic component, does not alter the position of the neutral plane of the flexible electronic component. 12. The article of claim 9, wherein the flexible support is defined by a bottom wall and a pair of opposing sidewalls extending upward from the bottom wall, a cavity being defined between the bottom wall and the pair of opposing sidewalls, the flexible electronic component being disposed within the cavity. 13. The article of claim 9, further comprising a spring element configured to apply tension to a portion of the flexible electronic component, the spring element having a first end fixedly attached to a portion of the flexible support and a second end fixedly attached to a corresponding portion of the flexible electronic component. 14. The article of claim 12, further comprising a flexible sheet coupled to the flexible support 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 flexible support when the article is bent along the first dimension and/or the second dimension. 15. The article of claim 9, wherein the flexible support is made of a first material, the article further comprising a second flexible support made of a second material, the second material having a lower Young's Modulus than the first material. 16. The article of claim 15, wherein the second flexible support defines a cavity and a slot, the flexible electronic component being disposed in the cavity and the flexible support being disposed in the slot. 17. The article of claim 1, wherein the flexible electronic component, when laid in a substantially flat position, defines a two-dimensional area in a reference plane, and wherein the bending limiting structure of the flexible support is configured to constrain bending of the flexible electronic component such that when the flexible electronic component is simultaneously bent along a first bending axis in the first dimension and a second bending axis in the second dimension, a first projection of the first bending axis onto the reference plane and a second projection of the second bending axis onto the reference plane do not intersect at a point located within the two-dimensional area of the reference plane.
