20200273384 · 2020-08-27 ·

Light leakage from integrally molding a decorative sheet and a connector insert is prevented. A molded article includes a display portion through which light can pass. A molded article body of the molded article includes a second molded portion made of a light-transmitting resin transmitting light guided to the display portion and a first molded portion made of an opaque resin having lower light transmittance than the second molded portion. A decorative sheet is integrally molded with the molded article body and includes a decorative portion that embellishes the display portion. A light-transmitting touch sensor sheet is integrally molded with the molded article body and transmits light that passes through the display portion. The molded article body includes a shade structure that is at least partly disposed around an outer peripheral edge of the decorative sheet and suppresses light passing through the light-transmitting resin.

INTEGRATED DEPTH SENSOR WINDOW LENS AND METHOD

A method of making an integrated depth sensor window lens, such as for an augmented reality (AR) head set, the depth sensor window lens comprising a sensor lens and an illuminator lens separated by an opaque dam. The method uses a two-shot injection molding process, a first shot comprising an optically clear polymeric material to form the sensor lens and the illuminator lens and the second shot comprising an opaque polymeric material to form the separator of the two.

Tailorable surface topology for antifouling coatings

Embodiments are directed to a method of making an antifouling and bactericidal coating with tailorable surface topology. The method includes depositing a layer of branched polyethyleneimine (BPEI) and diamino-functionalized poly(propylene oxide) (PPO) in a mixture of water and organic solvent on a substrate to form a layer of BPEI/PPO. The method includes depositing a layer of glyoxal in a water-containing solution on the layer of BPEI/PPO. The method further includes curing the layer of BPEI/PPO and layer of glyoxal to form a homogenous, glyoxal crosslinked BPEI/PPO coating, where the curing induces local precipitation and alteration of the glyoxal crosslinked BPEI/PPO coating to provide a textured surface.
