Abstract: The disclosure provides an electronic device including a housing, a light-emitting element and a light diffusion structure. The housing includes a first light-transmitting hole and a second light-transmitting hole. The light-emitting element is disposed in the housing, and is aligned with the first light-transmitting hole. The light diffusion structure includes a first light diffusion layer and a second light diffusion layer. The first light diffusion layer is disposed between the housing and the light-emitting element, and comprises a first semi-transparent region and a first light-shielding region. The first semi-transparent region corresponds to the first light-transmitting hole, and the first light-shielding region surrounds the first semi-transparent region. The second light diffusion layer is disposed between the housing and the light-emitting element, and comprises a second semi-transparent region and a second light-shielding region. The second semi-transparent region corresponds to the second light-transmitting hole. The second light-shielding region surrounds the second semi-transparent region.

Abstract: An electronic device and a knob module thereof are provided. The knob module includes a circuit board, a rotary encoder, a light guide structure, a plurality of light emitting units, and a rotation cover. The rotary encoder is disposed on the circuit board. The light guide structure is disposed on the circuit board. The light guide structure includes a light guide ring and an annular light guide wall. The light guide ring surrounds the rotary encoder. The annular light guide wall extends downward from the light guide ring to abut against the circuit board. The plurality of light emitting units is disposed on the circuit board and located between the annular light guide wall and the rotary encoder for emitting light toward the annular light guide wall. The rotation cover is disposed on the rotary encoder.
