Abstract: A hinge for a foldable electronic device includes a spine, a first hinge guide, a second hinge guide, and a display support. The first hinge guide is rotatably connected to the spine around a first axis. The second hinge guide rotatably connected to the spine around a second axis. The display support is connected to the first hinge guide in a first track and connected to the second hinge guide by a second track. A translational position of the display support relative to the spine is related to a first rotational position of the first hinge guide relative to the spine and a second rotational position of the second hinge guide relative to the spine.

Abstract: A hinged mobile computing device includes a first housing part with a first display and a second housing part with a second display. The first and second housing parts are coupled by a hinge assembly that includes a spring-loaded opening mechanism configured to bias with a biasing torque the first housing part and second housing part to rotate away from each other when the first and second displays are in a closed face-to-face orientation. An electro-magnetic closure system is configured to retain the first and second displays in the closed face-to-face orientation against the biasing torque of the spring-loaded opening mechanism, and release of the electro-magnetic closure system permits the first housing part to rotationally separate from the second housing part to a predetermined angular orientation due to the biasing force of the spring-loaded opening mechanism.

Abstract: Examples are disclosed relating to foldable display devices and methods for folding a display device through a range of degrees at a folding portion. In one example, a display device comprises a rear cover and a cover glass layer extending from a left side of the display device through the folding portion to a right side. A light-emitting layer is between the rear cover and the cover glass layer. A backplate is between the rear cover and the light-emitting layer, with the backplate comprising backplate slots that extend from an upper surface through a lower surface to facilitate bending of the backplate.
