ELECTRONIC DEVICE AND OPTICAL MODULE THEREOF

An electronic device including a first light source, a second light source, and a light guiding element is provided. The first light source provides a first light. The second light source provides a second light. The light guiding element includes a first microstructure, a second microstructure, and a light emitting surface. The first microstructure faces the first light source. The second microstructure faces the second light source. The first microstructure includes a plurality of first grooves. The first light enters the light guiding element through the first grooves, and exits the light guiding element via the light emitting surface. The second microstructure includes a plurality of second grooves. The second light enters the light guiding element through the second grooves, and exits the light guiding element via the light emitting surface.
