Abstract
An electronic device includes a substrate film having a first side and a second side, and a number of light sources configured to emit light. A plastic lightguide layer is molded onto the first side of the substrate film. The plastic lightguide layer being of optically at least translucent material to transmit light. The device also includes a masking layer provided on the outer surface of the plastic lightguide layer. The masking layer defines a window for letting the light emitted by the embedded light sources to pass through the masking layer towards the environment.
