摘要： An optical element (e.g., a lens) may include an optically uniaxial or optically biaxial organic solid, for example, an organic molecular solid. The direction of a maximum refractive index of the organic solid may be aligned substantially orthogonal to an optical axis of the lens. In some examples, a device may include a display and an optical configuration configured to receive light from the display and direct the light to a remote view location. In some examples, the optical configuration may comprise a lens and at least one surface of the lens may include a plurality of facets, for example, to form a Fresnel lens.

摘要： An optically anisotropic polymer thin film includes a crystallizable polymer and an additive configured to interact with the polymer (e.g., via π-π interactions) to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 50% of the molecular weight of the crystallizable polymer. Example crystallizable polymers include polyethylene naphthalate, polyethylene terephthalate, polybutylene naphthalate, polybutylene terephthalate, as well as derivatives thereof. Example additives, which may occupy up to approximately 10 wt. % of the polymer thin film, include aromatic ester oligomers, aromatic amide oligomers, and polycyclic aromatic hydrocarbons, for example. The optically anisotropic polymer thin film may be characterized by a refractive index greater than approximately 1.7 and an in-plane birefringence greater than approximately 0.2.

摘要： A camera device for integration into a wearable device is presented. The camera device includes an image sensor, a lens assembly, a first high density interconnect (HDI) tape substrate, a second HDI tape substrate, and a molded plastic layer. The molded plastic layer is sandwiched between the first and second HDI tape substrates. A wearable device with at least one soft electrode is further presented. The at least one soft electrode includes a conductive coating applied to an elastomer substrate and monitors electrical signals generated by a wearer of the wearable device to initiate an appropriate action. A method of forming an aggregate coating for a wearable device is further presented. One or more thin films are applied to a surface of the wearable device, and a paint coating is applied to a surface of the one or more thin films to form the aggregate coating.

摘要： A multilayer organic thin film includes a plurality of biaxially-oriented layers, where each layer is characterized by mutually orthogonal refractive indices, n1≠n2≠n3. In example structures, the corresponding in-plane refractive indices of adjacent layers may be rotated with respect to each other by a predetermined angle. Such a multilayer may be incorporated into a circular reflective polarizer, for example, which may be used in display systems to provide high broadband efficiency and high off-axis contrast. In an example process, individual organic thin films may be molded, and then oriented and stacked to form a multilayer.

摘要： A method of forming an organic solid crystal (OSC) thin film includes forming a layer of a non-volatile medium material over a surface of a mold, forming a layer of a molecular feedstock over a surface of the non-volatile medium material, the molecular feedstock including an organic solid crystal precursor, forming crystal nuclei from the organic solid crystal precursor, and growing the crystal nuclei to form the organic solid crystal thin film. An organic solid crystal (OSC) thin film may include a biaxially-oriented organic solid crystal layer having mutually orthogonal refractive indices, n1≠n2≠n3.

摘要： A polymer thin film includes polyethylene having a weight average molecular weight of at least approximately 500,000 g/mol, where the thin film is characterized by transparency within the visible spectrum of at least approximately 80%, bulk haze of less than approximately 5%, and an in-plane elastic modulus of at least approximately 10 GPa. The polymer thin film may be thermally conductive and may be incorporated into an optical element and configured to dissipate heat, such as from a light-emitting device.

摘要： An organic thin film includes an organic solid crystal material and has mutually orthogonal refractive indices, nx, ny, and nz each having a value at 589 nm of between approximately 1.5 and approximately 2.6, where nx≠ny≠nz. The organic thin film may be birefringent, and may be configured as a single layer thin film, or plural organic thin films may be stacked to form a multilayer that may be incorporated into an optical element, such as a reflective polarizer.

摘要： An organic thin film includes an organic crystalline phase, where the organic crystalline phase defines a surface having a surface roughness (Ra) of less than approximately 10 micrometers over an area of at least approximately 1 cm2. The organic thin film may be manufactured from an organic precursor and a non-volatile medium material that is configured to mediate the surface roughness of the organic crystalline phase during crystal nucleation and growth. The thin film may be formed using a suitably shaped mold, for example, and the non-volatile medium material may be disposed between a layer of the organic precursor and the mold during processing.

摘要： A thin film assembly includes an optical thin film and a discontinuous spacer layer disposed over a major surface of the optical thin film. Within a multilayer stack of optical thin films, the spacer layer may be located between opposing regions of adjacent thin films such that the spacer layer separates the adjacent thin films and inhibits or prevents surface-to-surface contact.
