  • Publication number: 20240275875
    Abstract: A foldable-display type portable terminal has a flexible display mounted thereon and can be folded and unfolded by an external force. The portable terminal includes a body having a first panel, an adjacent second panel, and a hinge part between and connecting the first and second panels, permitting the first and second panels to rotate with respect to each other. A flexible display on the upper surface of the body folds with the first and second panels when the first and second panels are folded about the hinge part. In one alternative, a support member beneath the flexible display covers the upper part of the hinge part and supports the lower part of the flexible display. In another alternative, a support rotatably installed at the body is arranged inside the body and folded at the upper part of the flexible display when the first and second panels are folded.

  • Patent number: 8582280
    Abstract: A foldable keyboard for a portable computer includes a keyboard body which comprises two keyboard pieces hinge-coupled by a hinge unit in order to be unfolded in a direction parallel to a keyboard plane. Another embodiment of the invention is a foldable keyboard, which includes: a guide unit at which a long hole is formed along its length; and a keyboard body which comprises two keyboard pieces hinge-coupled to the guide unit by a hinge unit. The keyboard pieces can be unfolded in a direction parallel to a keyboard plane into its extended state. As the keyboard pieces unfold, the hinge unit slides along the long hole as the keyboard edges, which are facing each other, are stuck together. Thus, the two keyboard pieces are hinge-coupled to each other to reverse their vertical and horizontal directions as the keyboard body is extended.
