The supporting substrate integrally includes wiring that couples driving power output by power supplying circuit element to the plural light sources. A rear receiving frame includes an integral heat-sinking and dissipating recess or groove that is positioned and dimensioned to receive the power supplying circuit element when the supporting substrate is received by the rear receiving frame. The integral heat-sinking and dissipating recess or groove removes heat from the heat generating and power supplying circuit element so that such heat does not adversely affect performance of the light sources.

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.

The driving part includes a red LED-driving element that provides the red LEDs with a driving voltage, a green LED-driving element that provides the green LEDs with a driving voltage, and a blue LED-driving element that provides the blue LEDs with a driving voltage. LEDs may be driven together in a group, or may be driven individually to sequentially emit red light, green light, and blue light so a color filter is not included in a display panel having the backlight assembly. A driving element is connected to the LEDs to reduce manufacturing costs for the driving element circuits, thereby reducing manufacturing costs of the backlight assembly.

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： A method of driving light sources controls amounts of light from light-emitting diode (LED) strings based on pulse signals to operate the LED strings connected in parallel. Voltages are synchronized with the pulse signals at input terminals of control circuits to detect the voltages, the control circuits being connected to the LED strings and controlling resistance variations of the LED strings. The operation of the LED strings is stopped when the detected voltage is out of a predetermined allowable voltage range due to a short-circuited LED. Therefore, a light source device may be protected by stopping the operation of the LED strings.
