摘要： The line banding image artifact that results from the interaction of LCD ripple and LED flicker in an LCD device that utilizes LED backlighting strings is substantially reduced by selecting a number of LED strings, individually driving the number of LED strings with a corresponding number of identical clock signals that are equally phase delayed, and selecting the frequency of the clock signals so that the product of the frequency of the clock signal multiplied by the number of LED strings is equal to the line clock frequency.
