  • Patent number: 11907027
    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.

  • Patent number: 10701824
    Abstract: A bending module and a folding display device are provided. The bending module is adapted to vary between a flattened state and a bent state. The bending module includes a flexible unit and a pair of supporting members. The flexible unit has a neutral layer, and the pair of supporting members are connected to the flexible unit. When the bending module varies between the flattened state and the bent state, the flexible unit is deformed, and the supporting members are each rotated via one corresponding center of rotation to be relatively close to or far from each other, wherein the centers of rotation are always maintained on the neutral layer of the flexible unit. By applying the bending module to the folding display device, the service life of the folding display device may be extended.
