Abstract: Driving a LED array includes determining total charge to be transferred to the LEDs during an image frame, and determining a number of drive pulses of equal width and amplitude that would drive the LEDs with nearly the total charge during display of the image frame.

If the width is less than the minimum width and if the amplitude is equal to the minimum amplitude and if the number of drive pulses is greater than one, the number is decremented.
