Abstract
A display device includes at least one light source array configured to provide a display panel with light, a dimming signal generating unit configured to receive an image data signal and generate a dimming signal, a first comparator configured to receive the dimming signal output from the dimming signal generating unit and a preset critical value and generate a comparison signal, a dimming modulating unit configured to receive the comparison signal output from the first comparator and the dimming signal output from the dimming signal generating unit and modulate the dimming signal, a constant current controller configured to receive the dimming signal output from the dimming modulating unit and a voltage from a sensor node, and to control a light driving current driving the light source array, and a resistor controller configured to change resistors connected to the sensor node by the comparison signal output from the first comparator.
