Abstract
An optical device includes: an addressable LED group having ARGB LED units which are connected in series and controlled serially by a specific sequence of digital signals to display colors; an input interface circuit, configured to sense a user's control state; a control circuit, coupled to the addressable LED group and the input interface circuit; a processing circuit, for providing an optical operation; a specific signal port of the processing circuit, coupled to the addressable LED group and coupled to the input interface circuit through the control circuit, configured to receive the specific sequence of digital signals and then transmit the specific sequence of digital signals into an input of a first addressable LED unit in the addressable LED group, and configured to receive an output control signal generated from the input interface circuit by sensing the user's control state.
