Abstract
A light emitting diode driver (LED) circuit and method are provided. The light emitting diode driver circuit includes an LED array; a LED driving circuit configured to supply current to the LED array through switching operations of a plurality of switches; and a driving controller configured to control the plurality of switches to supply current, corresponding to a dimming signal, to the LED array using a clock signal of a preset frequency. The driving controller may be further configured to control the plurality of switches to alternately perform switching operations.
