Abstract

A light-emitting diode (LED) dimming driving device includes a digital-to-analog converter (DAC) control signal generating unit and an LED driving signal generating unit. The DAC control signal generating unit generates a first control signal and a second control signal. The first control signal is input to the LED driving signal generating unit to generate a first driving current I, and the second control signal is input to the LED driving signal generating unit to generate a second driving current I. The first driving current Iis less than a maximum power current value Icorresponding to a peak power of the LED driving signal generating unit, and the second driving current Iis greater than the maximum power current value Icorresponding to the peak power of the LED driving signal generating unit.
