Abstract
We propose an oxide semiconductor thin‐film transistor‐based micro light‐emitting diode pixel circuit with external current setting system. The proposed circuit achieved stable operation using pulse width modulation with maximum error rates 1.2 % and 3.2 % under threshold voltage variations and mobility variations, respectively.
