Patent number: 11294431Abstract: A portable information handling system supports a flexible OLED display film over housing portions rotationally coupled by a hinge by folding the OLED display film over the hinge. Hinge brackets that couple to the housing portions each have a helical member that extends into an associated helical guide of the hinge main body. Hinge bracket rotation translates through the helical guides for synchronized housing rotation. The hinge main body has first and second circular portions extending along its length to define first and second rotation axes about which the hinge brackets pivot so that the display film has space to fold in the closed position.Type: GrantFiled: August 2, 2019Date of Patent: April 5, 2022Assignee: Dell Products L.P.Inventors: Christopher A.
