Abstract
A light emitting diode driving circuit includes connected driving units, each of which is configured for driving multiple channels of light emitting diodes generating a feedback voltage for the corresponding driving unit. Each of the driving units includes a selection circuit for comparing the feedback voltage with an input voltage to output a smaller one of the feedback voltage and the input voltage to a next one of the driving units, as the input voltage for the next one of the driving units.
