Claim 0:
1. A micro-light-emitting diode (LED) array comprising:
a pulse width modulator configured to generate a plurality of pulse width modulation (PWM) signals;
a first power supply line;
a second power supply line; and
a plurality of pixel assemblies, each pixel assembly comprising:
an LED coupled to the first power supply line;
a switching circuit configured to receive a respective, different PWM signal of the plurality of PWM signals and alternately turn on and off the LED according to the received PWM signal; and
a close loop circuit coupled to the second power supply line and configured to regulate an input current provided by the switching circuit to the LED based on a feedback signal.
