Claim 10:
11. A method of an optical device, comprising:
providing an addressable light-emission-diode (LED) group having a plurality of addressable red/green/blue (ARGB) LED units which are connected in series and controlled serially by a specific sequence of digital signals to display colors;
providing an input interface circuit to sense a user's control state;
providing a control circuit coupled to the addressable LED group and the input interface circuit;
using a processing circuit for providing an optical operation; and
providing 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, and using the specific signal port 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 in an addressable RGB mode and to receive an output control signal generated from the input interface circuit by sensing the user's control state in an input control mode.
