The two book halves is connected to each other via a hinge mechanism. The hinge mechanism has two hinges, and each hinge is rotatable about respective axis. Each of the two main display supports connects to one of the two book halves and is configured to support the flexible display. The coupling is connected to the two main display supports and rotating about a rotation axis that is parallel to the axis of hinge to enable a synchronized movement of the two main display supports. ## Claims ### Claim 1 A display system comprising: a flexible display; a first main display support and a second main display support configured to support the flexible display; a hinge mechanism configured to rotatably connect the first main display support and second main display support so that the flexible display is folded in a closed position and unfolded in an open position; and an additional display support comprising a first side support plate, a second side support plate, and a central support plate, the additional display support being configured to support a central segment of the flexible display in the open position, wherein the first side support plate and the second side support plate are disposed between the first main display support and the second main display support, wherein the central support plate is disposed between the first side support plate and the second side support plate and is pivotably connected to the first side support plate and the second side support plate, and wherein, during movement of the first main display support and the second main display support from the closed position to the open position, the central support plate is moved vertically upward with respect to a portion of the hinge mechanism while simultaneously the first side support plate and the second side support plate are moved downward with respect to the hinge mechanism. ### Claim 2 (depends on 1) The display system of claim 1, wherein the additional display support is pivotably connected to the first main display support and second main display support. ### Claim 3 (depends on 1) The display system of claim 1, wherein the additional display support further comprises a first support plate and a second support plate movably connected to the central support plate, and wherein the first support plate and the second support plate are pivotably connected to the first main display support and the second main display support, respectively. ### Claim 4 (depends on 3) The display system of claim 3, wherein a first end of the central support plate is pivotably connected to a first end of the first side support plate and a second end of the central support plate is pivotably connected to a first end of the second side support plate. ### Claim 5 (depends on 1) The display system of claim 1, wherein the central support plate moves in one direction toward the flexible display while the flexible display is being unfolded, and wherein the central support plate moves in a direction opposite to the one direction while the flexible display is being folded. ### Claim 6 (depends on 1) The display system of claim 1, wherein the central support plate, the first side support plate, and second side support plate support the central display segment so that the central display segment is bent at a pre-defined curvature in the closed position. ### Claim 7 (depends on 1) The display system of claim 1, wherein the hinge mechanism comprises a first hinge axis and a second hinge axis that rotatably connect the first main display support and the second main display support, respectively. ### Claim 8 (depends on 1) The display system of claim 1, wherein, during movement of the first main display support and the second main display support from the open position to the closed position, the central support plate is moved vertically downward with respect to the portion of the hinge mechanism while simultaneously the first side support plate and the second side support plate are moved upward with respect to the hinge mechanism.
