ILLUMINATED MULTILAYER STRUCTURE WITH EMBEDDED AREA LIGHT SOURCE

Multilayer assembly for an electronic device includes a substrate film configured to accommodate electronics, said film having the first side and a second side, at least one area light source and configured to emit light of predetermined frequency or frequency band, a molded lightguide layer, the lightguide layer being of optically at least translucent material, wherein the lightguide layer is configured to transmit light emitted by the embedded light source so that the transmitted light propagates within the lightguide layer and is outcoupled therefrom via an outer surface thereof substantially opposite to the embedded light source, and a masking layer provided on the outer surface of the plastic lightguide layer, containing substantially opaque material to block external view of at least some internals of the multilayer structure, wherein the masking layer defines a window for letting the light emitted by the embedded light source and propagated within the plastic lightguide layer to pass through the masking layer towards the environment.
