Abstract
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 gear member with a semicircular shape gear inner circumference that engages a gear subassembly of the hinge main body. Hinge bracket rotation translates through the gear subassembly for synchronized housing rotation. The hinge main body has first and second semicircular portions with a smooth surface defined to accept the outer circumference smooth surface of the gear member semicircular shape at first and second rotation axes about which the hinge brackets pivot so that the display film has space to fold in the closed position.
