US Patent 10429903 Flexible information handling system display external hinge structure

An information handling system having rotationally coupled housing portions supports a flexible display disposed across the housing portions with a hinge structure that manages flexible display curve radius in a folded configuration. The hinge includes plural hinge elements having an arc face, arc cavity interior and mounts that couple with hinge coupling elements. The mounts align the hinge coupling element rotational axis out of the cavity to aid in maintaining the hinge elements having no gaps during rotation of the information handling system housing portions. The hinge coupling element integrates friction plates disposed normal the rotation axis to generate torque for managing housing rotational movement.
