Abstract: This application discloses a method for an optical drive chip to control a light-emitting device and an optical drive chip thereof. A receiving unit of the optical drive chip obtains to-be-sent data, and transmits the to-be-sent data to an execution unit of the optical drive chip; and the execution unit converts the to-be-sent data into a drive signal according to a control parameter set, where the drive signal is used to control a light-emitting device to emit visible light. Because the optical drive chip converts the to-be-sent data into the drive signal according to the control parameter set so as to control the light-emitting device, rather than obtaining a single control parameter one by one to control the light-emitting device, no delay problem occurs in a process of controlling the light-emitting device by the optical drive chip. In addition, the to-be-sent data is encoded, which ensures data transmission reliability.
