ELECTRONIC DEVICE HAVING STRUCTURED FLEXIBLE SUBSTRATES WITH BENDS

摘要

A flexible substrate may be provided with an array of holes and conductive traces that extend along the flexible substrate between the holes. The flexible substrate may form part of a display or other component in an electronic device. The conductive traces may be metal traces that have meandering path shapes to resist damage upon bending. A polymer coating may be applied over the metal traces to align a neutral stress plane with the metal traces and to serve as a moisture barrier. The holes may allow the flexible substrate to twist and form a three-dimensional shape as the flexible substrate is bent. A rigid or flexible protective coating may be formed by depositing a liquid polymer precursor on the flexible substrate and curing the liquid polymer precursor.
