Abstract: Electronic Devices Incorporating Flexible Component Layers with Interlocking Devices At least some aspects of the present disclosure directs to an electronic device 100 comprising a rigid member 100A, 100B, a flexible component layer 130, and an interlocking device 110A, HOB disposed between the flexible component layer and the rigid member. The flexible component layer has at least two sections when the flexible component layer is flexed. The interlocking device comprises a first interlocking component attached to or integrated with the flexible component layer, and a second interlocking component attached to or integrated with the rigid member configured to engage with the first interlocking component, such that the engagement prevents the separation of the flexible component layer from the rigid member along a direction generally perpendicular to a surface of the rigid member.

Abstract: The present invention is an assembly layer for a flexible device. The assembly layer is derived from precursors that include an alkyl(meth)acrylate ester having 1 to 24 carbon atoms in the alkyl group and a free-radical generating initiator. Within a temperature range of between −30° C. to 90° C., the assembly layer has a shear storage modulus at a frequency of 1 Hz that does not exceed 2 MPa, a shear creep compliance (J) of at least 6×10″6 1/Pa measured at 5 seconds with an applied shear stress between 50 kPa and 500 kPa, and a strain recovery of at least 50% at at least one point of applied shear stress within the range of 5 kPa to 500 kPa within 1 minute after removing the applied shear stress. In a preferred embodiment, the flexible device is a flexible electronic display.
