  • Patent number: 11961775
    Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

  • Patent number: 9639121
    Abstract: A foldable display is disclosed. In one aspect, the foldable display includes a base substrate including a flexible area and a rigid area disposed at one or more sides of the flexible area. The foldable display also includes an image display device provided on the base substrate. The base substrate includes a matrix and a textile implanted in the matrix. The textile includes a flexible part corresponding to the flexible area and a rigid part corresponding to the rigid area. The rigid part is weaved differently from the flexible part.

  • Patent number: 9429999
    Abstract: A foldable display device is disclosed. In one aspect, the foldable display device includes a display panel and a window panel on the display panel. The window panel includes a folding area and a flat area adjacent to at least one side of the folding area. The flat area is less flexible than the folding area. An elastic modulus of the folding area is less than an elastic modulus of the flat area. The window panel includes a plurality of layers including a first layer, wherein a first thickness of the first layer in the folding area is different from a second thickness of the first layer in the flat area.

  • Patent number: 9354476
    Abstract: A window panel includes a first rigid part including a rigid material, a second rigid part including the rigid material, and a base substrate interposed between the first and second rigid parts and including a folding part configured to be folded by an external force. The folding part includes a first area and a second area, which are alternately arranged on a plane surface of the base substrate substantially perpendicular to a thickness direction of the base substrate. The first area includes the rigid material, and at least a portion of the second area includes a soft material. Thus, the rigidity of the window panel is maintained by the rigid material and the flexibility of the window panel is improved by the soft material.
