  • Patent number: 10833436
    Abstract: An electrical connector carries large amounts of electrical current between two circuit boards with low resistance and low self-inductance by means of an interdigitated anode and cathode, thereby providing low dynamic voltage loss. The connector also may include, near where power will be consumed, an interposer board with on-board capacitance to provide even lower dynamic voltage loss. The connector has application to delivering low-voltage, high-current power from a power supply on a first board to electronics on a second board: the low resistance provides low voltage drop for a load current that is constant, while the low inductance and the capacitors provide low voltage fluctuation for a load current that changes. These issues are of great importance, for example, in designing high-performance computers.

In a closed position, the sliding support compresses by fully engaging the fingers so that room is provided over a hinge assembly that rotationally couples the housing to provide folding of the flexible display without wrinkling or compression.

  • Patent number: 10795415
    Abstract: A foldable display has multiple layers, including at least a display layer that creates the display that users see when looking at the foldable display and a stiff support layer that provides the display layer with support despite the foldable nature of the display. An adhesive layer binds the display layer to the stiff support layer. The stiff support layer has a stiffness that is at least six times greater than the stiffness of the adhesive layer and at least six times greater than the stiffness of the display layer. Given the foldable nature of the display, there is typically a hinge system below part of the display. In situations in which pressure is applied to the foldable display (e.g., by a user's finger or stylus), the stiffness of the stiff support layer prevents the display from being damaged despite the presence of the hinge system.

  • Patent number: 10782830
    Abstract: Provided is a flexible touch sensor having a foldable area and a non-foldable area, including: first touch electrodes placed in the non-foldable area; second touch electrodes; a third touch electrode placed in the foldable area, the third touch electrode not overlapping a portion of the second touch electrode in the foldable area; and an insulation layer placed in the non-foldable area and insulated from the second touch electrodes by the insulation layer. Further provided is a flexible touch display panel including the flexible touch sensor. The above solution thins the stacked film layers in the foldable area; further, the foldable area has no insulation layer that easily cracks, so that bending stability of the foldable area is improved, and the flexible touch sensor can still have good touch performance even after repeatedly bending.
