摘要： A light source driving circuit and method is provided. The light source driving circuit includes a light source for outputting light, a light receiving unit for detecting a portion of the light output from the light source, a switching unit for controlling the supply of a source voltage according to an operation control signal, a constant current source for supplying a current corresponding to a threshold current to the light source according to the control of the switching unit, and an automatic power controller for controlling a driving current of the light source in response to an external modulation signal. Accordingly, by supplying a current corresponding to a threshold current of a green laser by means of a switching operation according to an operation control signal for a set time before a modulation signal of the green laser is input, a turn-on delay of the green laser can be reduced.
