摘要： A pressure sensitive adhesive surface that does not adhere to the adherend and can be positioned by sliding it under low pressure, while it can exert a sufficient adhesive force under a pressure above a certain level. The adhesive sheet includes an adhesive layer with a fine structure on a surface thereof. The fine structure includes a plurality of cone or frustum structures, with the cones or frustums having two or more parts joined to each other via an interface. A first part is present on a top of the cones or frustums and is formed from a non-adhesive or a weak adhesive material, and a second part is present below the first part and is formed from a strong adhesive material.

摘要： In devices with flexible displays, multilayer adhesive stacks may be included. A multilayer adhesive may attach a flexible display panel to the display cover layer in an electronic device. Including multiple layers of adhesive in the adhesive stack (as opposed to a single layer) provides more degrees of freedom for the tuning and optimization of the properties of the adhesive stack. The multilayer adhesive stack therefore has better performance than if only a single layer of adhesive is used. The multilayer adhesive stack may include one or more layers of soft adhesive, hard adhesive, hard elastomer, hard polymer, and/or glass to optimize the mechanical and optical performance of the multilayer adhesive stack. Soft adhesive layers may be included to optimize lateral decoupling (e.g., during folding and unfolding) of the adhesive stack. Harder layers may be included to provide rigidity and prevent denting during impact events.
