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.

摘要： A backlight unit assembly, a liquid crystal display having the same, and a dimming method thereof are provided. The dimming method for a liquid crystal display includes setting a plurality of lookup tables, each lookup table having different data for adjusting luminance corresponding to a same grayscale, calculating a grayscale average of a whole liquid crystal display panel and grayscale averages of individual liquid crystal display panel blocks with respect to an image signal input to the liquid crystal display panel, selecting one of the plurality of lookup tables in accordance with the whole grayscale average, and calculating the data for obtaining the luminance corresponding to the individual grayscale averages in the selected lookup table, and adjusting and applying power to a light emitting diode assembly using the calculated data. In the case of displaying an image, which is dark on the whole and only a part of which is bright, power is applied with a wider pulse width at the same grayscale, and thus the image can be displayed with a desired luminance to minimize image distortion.
