  • Patent number: 12253756
    Abstract: An electronic device including a first light emitting unit, a second light emitting unit, a first optical layer and a second optical layer is disclosed. The first light emitting unit emits a first light. The second light emitting unit emits a second light. At least one of the first light and the second light passes through the first optical layer. The second optical layer is overlapped with the first optical layer. The second optical layer is configured to scatter the first light emitted from the first light emitting unit. When the first light emitting unit emits the first light, the second light emitting unit selectively emits the second light.

  • Patent number: 9509419
    Abstract: A communication circuit includes a receiver path, a frequency translating loop filter and a signal source circuit. The frequency translating loop filter includes an auxiliary mixer, and a frequency translating filter backend circuit such as a filter. The signal source circuit can be shared with a transmitter path. When the receiver path receives an external signal, the auxiliary mixer and the frequency translating filter backend circuit perform high-frequency filtering. When the receiver path need not receive the external signal, the auxiliary mixer up-converts a low-frequency auxiliary signal provided by the signal source circuit to a high-frequency domain, and the up-converted signal is received by the receiver path. Thus, an operation parameter of the receiver path can be adjusted and calibrated according to a response of the receiver path.
