Abstract: Embodiments of this application provide example holographic recording media, holographic polymer materials, methods for preparing holographic polymer materials, and display devices. An example holographic recording medium includes a first-order crosslinked network, a photoinitiator, and a second-order monomer. The first-order crosslinked network provides a mechanical support for the holographic recording medium. The second-order monomer includes a monomer with a free radical reactivity. The photoinitiator is used to initiate polymerization of the second-order monomer. The holographic recording medium includes at least one of an ester group (I), a urethane group (II), a carbamido group (III), an allophanate group (IV), or an amide group (V). Groups linked to the ester group (I), the urethane group (II), the carbamido group (III), the allophanate group (IV), and the amide group (V) are separately selected from at least one of the following: alkyl, alkoxy, alkenyl, or aryl.

Abstract: In some examples, a semiconductor package comprises an electrically conductive surface and a bond wire coupled to the electrically conductive surface. The bond wire includes a first stitch bond coupled to the electrically conductive surface, and a second stitch bond contiguous with the first stitch bond and coupled to the electrically conductive surface. The second stitch bond is partially, but not completely, overlapping with the first stitch bond.
