Abstract
An electronic device includes a casing including an annular light-emitting area, a plurality of directly-lit light sources, a light guide plate disposed between the directly-lit light sources and the annular light-emitting area, and a light-shielding rib structure located between the directly-lit light sources, and separating any two adjacent ones of the directly-lit light sources. The light guide plate includes opposite first and second surfaces and a plurality of recessed structures recessed in the second surface. The recessed structure has a corresponding semi-conical surface, and the semi-conical surface faces a zone of the light guide plate. The directly-lit light sources face the first surface and respectively correspond to the semi-conical surfaces. Light emitted by the directly-lit light sources enters the light guide plate and is reflected by the semi-conical surfaces, passes through the zones of the light guide plate, and is transmitted to the annular light-emitting area to emit outwardly.
