A novel 16 bit average separated PWM algorithm is presented with which the driver can precisely dim LED light output over the full range from 100% to 0%.Compared with conventional PWM dimming.the PWM waveform is averagely divided into several sections in a whole PWM period.and the grayscale data are separated by binary power value,in order to enhance the uniformity of the gray and diminish the influence of high significant bit on uniformity.Furthermore,this progressive algorithm could efficiently reduce fli...
