Abstract: A display driver has current reference units and current-generating units. Each current reference unit generates a reference current and scaling it to form a scaled reference current. Each current-generating unit generates an output current from one scaled reference current to drive a selected light emitter (LE) of a LE matrix over a time slice allocated for driving the selected LE. Each current-generating unit has a switching circuit modulating the scaled reference current according to a switching sequence to form output current pulses to drive a LE.
