We proposed a micro light-emitting diode (μLED) pixel circuit using quaternary digital driving. The proposed circuit used a stepwise signal to control the emission time. The proposed circuit exhibited a low delay time below 500 ns and an error rate below 3% with a threshold voltage shift of ±0.5 V.
