Abstract

Microscopic light emitting diodes (micro-LEDs) systems with bridge circuits for scaling voltages and currents are described. An example micro-LED system includes a set of micro-LEDs having a respective voltage terminal configured to receive a first positive voltage supply and a common cathode terminal configured to receive a negative voltage supply. The micro-LED system includes sensing circuits to sense voltages and currents received from a selected subset of the set of micro-LEDs, where each of the sensing circuits is configured to receive a second positive voltage supply, different from the first positive voltage supply. The micro-LED system includes bridge circuits to: (1) during sensing of any voltages received from a selected subset of the set of micro-LEDs, scale voltages to scaled voltages, and (2) during sensing of any current received from a selected subset of the set of micro-LEDs, limit current flowing through a respective sensing circuit.
