Abstract:
An apparatus for driving light-emitting diodes includes first and second light-emitting diode auxiliary drive parts for controlling the lighting of first and second light-emitting diode parts depending on the currents flowing through the first and second light-emitting diode parts, respectively detected by first and second resistors. Each of the first light-emitting diode auxiliary drive part and the second light-emitting diode auxiliary drive part includes a first transistor, a second transistor, and a third transistor.
