DESCRIPTION OF PARTICULAR EMBODIMENT(S)
(11) In the following description, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are exemplary and not exhaustive of all possible embodiments.
(12) As used herein, a hyphenated form of a reference numeral refers to a specific instance of an element and the un-hyphenated form of the reference numeral refers to the collective or generic element. Thus, for example, widget 72-1 refers to an instance of a widget class, which may be referred to collectively as widgets 72 and any one of which may be referred to generically as a widget 72.
(13) As noted previously, portable information handling systems may include one or more flexible displays. Such displays may bend as the portable information handling system is rotated, bent, and/or adjusted to different positions. Such bending may cause stress (e.g., tensile stress) on the flexible display at or near the bend location(s), which in turn may affect the structural integrity, performance, and/or durability of the display. For example, a flexible display may extend over a portion of a hinge assembly rotationally coupling housing portions of the portable information handling system. As the housing portions rotate to different positions relative to each other, the flexible display may bend at different degrees, resulting in varying amounts of stress on the flexible display at or near the hinge location. As described in more detail below, the hinge assembly may be designed to control and reduce the stress on the flexible display as the housing portions are rotated.

(25) In some embodiments, portable information handling system 200 may include one or more displays for visually presenting information. For example, display 146 may be touch panel 142 with circuitry enabling touch functionality in conjunction with a display such that a user may provide input to portable information handling system 200 through the display. In some embodiments, display 146 may be flexible such that it can bend and change shapes while still visually presenting information to and/or accepting input from the user. For example, display 146 may be an organic light-emitting diode (OLED) formed on a flexible plastic, such as polyethylene terephthalate. In some embodiments, display 146 may couple to main housing portion 202 and lid housing portion 204 such that display 146 extends over at least some portion of hinge assembly 206. In some embodiments, main housing portion 202 may include a keyboard on a top portion of main housing portion 202. In some embodiments, display 146 may be placed over main housing portion 202, lid housing portion 204, and hinge assembly 206 and configured to bend when the hinge assembly bends.
(26) As explained below in further detail, hinge assembly 206 allows main housing portion 202 and lid housing portion 204 to rotate between a plurality of positions. For example, when portable information handling system 200 is not in use, lid housing portion 204 may be closed over the top of main housing portion 202 so that display 146 is protected from unintended use or damage. Display 146 may also bend at varying degrees as portable information handling system 200 is moved between positions. In any position, user inputs may be communicated to an I/O subsystem and/or processor subsystem of the portable information handling system for processing, and then updated information may be communicated back to display 146 for displaying to the user.

(28) As discussed above with respect to
(29) In some embodiments, the hinge assembly of the portable information handling system may include one or more hinges and a deformable foam. For example, hinge assembly 206 may include hinges 210-1 and 210-2, and deformable foam 220 coupled to main housing portion 202 and lid housing portion 204 of portable information handling system 200. Hinges 210 may fold and bend in both directions in relation to each other so that main housing portion 202 may rotate in relation to lid housing portion 204. As shown, hinges 210, e.g. hinges 210-1 and 210-2, may be in an approximate 0 degree hinge closed position or an approximate 360 degree hinge open position. Deformable foam 220 may include a lid housing area 305, a main housing area 303, and a hinge assembly area 307. As shown, hinge assembly area 307 of deformable foam 220 may also fold and bend between an approximate 0 degree position and a 360 degree position in both directions in relation to hinges 210-1 and 210-2 so that main housing portion 202 may rotate in relation to lid housing portion 204.
(30) In some embodiments, hinges 210 may be comprised of spring steel sheets that may be deformable to allow hinges 210 to bend between approximately 0 and 360 degrees and return to its original shape. As shown, a hinge 210 may be in an approximate 0 degree hinge closed position or an approximate 360 degree hinge open position. The spring steel sheets of hinges 210 may be comprised of at least one of a low-alloy medium-carbon steel and a high-carbon steel with a very high yield strength to dissipate the energy of bending hinges 210 and enhance their long term reliability.
(31) In some embodiments, hinges 210-1 and 210-2 may be comprised of a fiber including deformable foam 220 in between hinges 210-1 and 210-2. The fiber may provide bending and deformation properties of hinges 210. The fiber of hinges 210 may be comprised of one or more of an Aramid fiber, and other polymeric fiber.

Main housing area 303 and lid housing area 305 of deformable foam 220 may be further comprised of a nano-fiber based foam laminate, an Aramid fiber loaded with carbon nanotube, a polymeric fiber composite including a carbon nanotube fiber, and other suitable materials, which may provide additional stiffening or creek resistance properties to main housing area 303 and lid housing area 305 of deformable foam 220 that may be needed based on the size of a display, while hinge assembly area 307 has a reduced stiffness. For example, a larger display, equal to or greater than an 11 diagonal, may benefit from additional stiffness, where every three inch (3) increase in the diagonal size of the display may benefit from an additional ten percent (10%) increase in stiffness.
(33) Hinges 210-1 and 210-2 and deformable foam 220 of hinge assembly 206 may be foldable, bendable and deformable while maintaining the structural integrity of hinge assembly 206. The selection of the shape, design, and material for hinges 210 and deformable foam 220 may be based on cost, durability, weight, and/or other considerations.

(35) Form portion 440 may have an anisotropic shape to guide directional deformation of deformable foam 220 in certain directions when it is deformed in relation to hinges 210 being folded or bent. In
(36) Foam side portions 446 may be bonded to foam top portion 442 and foam bottom portion 444 using a structural adhesive. For example, the structural adhesive may be an epoxy adhesive, an Ester of an Epoxy (EPE) resin, a ultra-violet curable epoxy, an infrared curable epoxy, a resin including a hardener, a resin including a flexible hardener, an Acrylic adhesive, a Urethane adhesive, and other types of structural adhesives. Foam channel portion 448 may be between foam portion 440 and foam top portion 442 and may be filled with a structure adhesive, e.g. one of the structural adhesives described above. Foam top portion 442 may be partially perforated to further improve the bond.
