Abstract
An electronic device such as a wrist band may include a strip of fabric that wraps around a longitudinal axis. A one-dimensional array of light sources may be embedded in the strip of fabric and may emit light parallel to the longitudinal axis to produce edge illumination along an edge of the strip of fabric. Optical structures such as light-diffusing strands, light-diffusing polymer structures, and/or light guides may be located between the light sources and the edge of the strip of fabric to help diffuse light and/or guide light to the edge of the strip of fabric. Light-reflecting layers may be formed on inner surfaces of the fabric. Control circuitry may control the light sources to produce the edge illumination in response to an event occurring on an external electronic device such as a notification on an external display.
