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： A method of driving a light source, a light source apparatus for performing the method, and a display apparatus having the light source apparatus are disclosed in accordance with one or more embodiments. In the method, a plurality of light source strings connected in parallel is driven by applying a driving voltage to a first terminal of the light source strings. A peak current due to a voltage deviation of each of the light source strings is switch-controlled to uniform an average current of the light source strings. Thus, a peak current flowing through light source strings in accordance with a voltage deviation of the light source strings is switch-controlled, so that an average current of the light source strings may be uniformly maintained. Therefore, a voltage deviation is not consumed as power, so that damage to circuit elements due to heat may be prevented.

摘要： In a display apparatus having a backlight unit, a light unit includes plural light source strings commonly connected to an output terminal of a boosting circuit to generate light in response to a light source driving voltage. The light source strings are grouped into plural light generating groups. Plural driving circuits are respectively connected to the light generating groups, and each driving circuit sequentially outputs feedback voltages from the light source strings of a corresponding light generating group. A minimum voltage detecting circuit compares the feedback voltages with each other from the driving circuits to detect a minimum voltage and outputs a control signal according to the detected minimum voltage. A voltage control circuit controls a voltage level of the light source driving voltage in response to the control signal. Accordingly, although the number of the driving circuits increases, power consumption used in each driving circuit may be reduced.
