A micro light emitting diode (LED) die can include a matrix of micro LEDs with a variety of forward voltages. A method of reducing a number of undriven or under driven uLEDs can include providing, by a power supply, an alternating current voltage (VLED) with a minimum voltage (VMIN) and a maximum voltage (VMAX), VMIN being sufficient to drive a plurality of micro light emitting diodes (uLEDs) of a uLED die using a plurality of uLED drivers, identifying, by a controller coupled to the uLED drivers, a uLED of the plurality of uLEDs with a forward voltage (Vf) greater than VMIN, and altering, by the controller, a time of a rising edge of a pulse width modulation (PWM)-on time of the uLED such that Vf of the uLED is less than VLED for the PWM-on time.
