Active control of LEDs, LED packages, and related LED displays by way of pulse wide modulation (PWM) is disclosed. Effective PWM frequencies for LEDs are increased by segmenting duty cycles in which LEDs are electrically activated within individual PWM periods. Segmented duty cycles may be provided by transforming or re-ordering a sequence in which control signals are provided to LEDs. As such, LEDs may be electrically activated and deactivated multiple times within each PWM period. Active electrical elements that are incorporated into one or more LED packages of an LED display may be capable of segmenting the duty cycle within each LED package. Active electrical elements may also be capable of receiving reset signals from a data stream to either initiate a reset action or pass the reset signals along to other active electrical elements of a display.
