Abstract

A micro-light-emitting diode (micro-LED) display comprising a plurality of rows of light-emitting diodes (LEDs), each LED of the LEDs in a row including a channel wherein each channel includes a feedback path configured to feed an anode voltage of each LED to an input of a voltage comparator, a column driver comprising a digital to analog converter (DAC) and the voltage comparator, wherein the DAC is configured to receive a plurality of voltage inputs from the resistor ladder and to provide a corresponding plurality of voltage outputs to the input of the voltage comparator, and wherein the voltage comparator is configured to successively compare individual voltage outputs of the plurality of voltage outputs received from the DAC with the anode voltage of each LED, a data latch configured to store comparison results from the voltage comparator.
