Abstract:
A light emitting diode (LED) driving system drives a plurality of LED strings. A plurality of current sources are respectively connected to the plurality of LED strings. A multi-phase control signal generator generates a plurality of multi-phase control signals that respectively maintain turn on or turn off states of the current sources so as to selectively conduct the corresponding LED strings.
