Abstract: A display polarizer may have a polymer layer such as a polyvinyl alcohol layer coated with a dichroic dye such as iodine. A polymer layer such as a tri-acetyl cellulose layer may be formed on the polyvinyl alcohol layer so that the iodine is interposed between the polyvinyl alcohol layer and the tri-acetyl cellulose layer. To provide protection for the iodine layer, an additional polymer layer such as an additional tri-acetyl cellulose layer and a layer of adhesive may be formed on top of the polymer layer. A functional layer such as an antireflection layer may form an outermost layer in the polarizer. Compensation films may be formed beneath the polyvinyl alcohol layer. Additional display layers such as a lower polarizer layer and interposed layers such as a thin-film transistor layer, liquid crystal layer, and color filter layer may be formed below the compensation films.

Abstract: An electronic device such as a voice-controlled speaker device may have a cylindrical shape. The electronic device may include a housing, a speaker in the housing configured to emit sound, and a display in the housing. The display may include a substrate, light-emitting components mounted on the substrate, an opaque support structure mounted on the substrate, a diffuser that is mounted to the opaque support structure and that overlaps the light-emitting components, a display cover layer that overlaps the diffuser, and foam that is interposed between the opaque support structure and the display cover layer. The light-emitting components may be arranged in groups that have the same layout and orientations that vary as a function of angular position relative to the center of the display. The foam and/or an adhesive layer may be formed from two or more discrete pieces that have footprints with complementary protrusions.
