Abstract

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 flexible display is supported on a display frame that slides relative to a housing of the information handling system during rotation of housing portions. A biasing device provides force to the display frame in coordination with the sliding motion to reduce forces applied to the flexible display surface during housing portion rotations.

Claims (8)

1. An information handling system comprising: first and second housing portions, at least one of the housing portions containing processing components that cooperate to process information; first and second hinges coupled to opposing sides of the first and second housing portions, the first and second hinges rotationally coupling the first and second housing portions to rotate between at least planar and closed configurations; a flexible display disposed over at least one of the first and second housing portions, the flexible display bending as the first and second hinges rotate the first and second housing portions between the planar and the closed configurations; a sliding support disposed between at least one of the housing portions and the flexible display, the sliding support sliding the flexible display relative to the at least one of the housing portions during rotation of the housing portions; and a wire coupled to the sliding support and the other of the at least one housing portions, the wire pulling the sliding support towards the other of the housing portions relative to the at least one of the housing portions during rotation towards the planar configuration; and a biasing device coupled to the at least one of the housing portions and the sliding support, the biasing device biasing the sliding portion away from the other of the housing portions; wherein the biasing device pulls the sliding support towards the at least one of the housing portions during rotation towards the closed configuration.

2. The information handling system of claim 1 wherein the biasing device comprises a wire tensioned by a spring.

3. The information handling system of claim 1 wherein the flexible display comprises an OLED display film.

4. The information handling system of claim 3 wherein the OLED display is disposed over the first and second hinges.

5. The information handling system of claim 4 further comprising a shape memory alloy support in a fixed location relative to the first and second hinges, and configured to manage flexible display bend angles during rotation about the hinges.

6. The information handling system of claim 5 further comprising an interconnect bar fixedly coupled to the first and second hinges, the shape memory alloy support fixedly coupled to an upper surface of the interconnect bar.

7. The information handling system of claim 6 further comprising a shape memory alloy support coupled to a lower surface of the interconnect bar and configured to manage an outer housing surface curvature during rotation of the housing portions.

8. The system of claim 5 further comprising first and second rollers disposed at opposing ends of the first and second housing portions, each roller coupled to the flexible display to manage movement of the flexible display relative to the housing portions during rotation of the hinges.
