LIGHT-EMITTING DIODE DRIVING CIRCUIT

摘要

An exemplary light-emitting diode (LED) driving circuit includes a LED driving IC, at least a LED string and at least a resistor. The LED string each is electrically coupled between a power source voltage and a control terminal of the LED driving IC and whereby a driving current of the LED string is subjected to the control of the LED driving IC. The resistor each is electrically coupled to between the control terminal and a predetermined potential. Moreover, a LED driving method also is provided.
