Claim 18:
19. A foldable electronic device, comprising:
a foldable housing having a hinge configured to allow the foldable housing to bend about a bend axis;
an array of pixels that overlaps the bend axis; and
a glass layer that overlaps the array of pixels, wherein the glass layer has a recess that runs parallel to the bend axis and forms a flexible thinned portion in the glass layer that is configured to bend about the bend axis, wherein the flexible thinned portion has a rough inner surface coated by a polymer that fills the recess and that creates a glass-polymer interface in the recess, and wherein the rough inner surface creates a gradual change in refractive index between the glass layer and the polymer to reduce light reflections at the glass-polymer interface.
