ELECTRONIC DEVICE HOUSING HAVING TUNABLE METALLIC APPEARANCE

摘要

An electronic device (110, 210) includes a housing (120) encasing a component (112, 114). The housing (120) includes a region (300, 600, 800, 1000) contiguous to the component (112, 114), the region (300, 600, 800, 1000) configured to selectively switch between a metallic appearance to transparent to reveal the component (112, 114) through the region (300, 600, 800, 1000) when transparent. Metal surfaces, metal particles, or shiny particles that are incorporated into device structures may be actuated. The grain sizes of the particles can be adjusted to achieve the desired reflections. In addition, individual shutters (318, 618, 818. 1018) can be fabricated with a distribution of predisposed orientations to enhance the reflectivity.
