Abstract

A driving circuit for a light-emitting diode (LED) panel includes a first current source and a second current source. The first current source, coupled to a current source terminal of the driving circuit, is configured to output a first current to the LED panel through the current source terminal. The second current source, coupled to a current sink terminal of the driving circuit, is configured to receive a second current from the LED panel through the current sink terminal.
