摘要： A display device with improved display quality is provided. The display device includes an LED light source emitting light, a display panel receiving the light to display an image, and a backlight driver adjusting the magnitude and the duty ratio of an LED current I_LED flowing through the LED light source. The waveform of the LED current I_LED includes at least one of a rising section in which the magnitude of the LED current more gradually increases from a turn-off current value to a peak value, and a falling section in which the magnitude of the LED current more gradually decreases from the peak value to the turn-off current value. This acts to reduce waterfall noise.

摘要： In order to perform local dimming, a driving dimming duty cycle is generated using a target gamma curve (TGV), wherein the driving dimming duty cycle corresponds to a representative grayscale value (RGV) of each of a plurality of dimming unit areas. Each of a plurality of light unit blocks of a light source is driven based on the driving dimming duty cycle, wherein the light unit blocks correspond to the dimming unit areas, respectively. Therefore, a display apparatus may display an image having a higher contrast ratio than normal.
