The electronic device includes a hinge housing coupling the first device housing to the second device housing. The hinge housing provides a hinge allowing the first device housing to pivot about the hinge housing between an axially displaced open position and a closed position. A hinge housing plate situated within the hinge housing translates within the hinge housing between a first position and a second position when the first device housing and the second device housing pivot about the hinge housing from the axially displaced open position to the closed position, thereby allowing at least a portion of a service loop defined by a flexible display to situate within the hinge housing when the first device housing and second device housing are in the closed position. ## Claims ### Claim 1 An electronic device, comprising: a first device housing and a second device housing;
