This work proposes an oxide-based pixel circuit for micro light-emitting diode (micro-LED) display with pulse width modulation (PWM) driving, which prevents the wavelength shift of the micro-LED. The proposed pixel circuit utilizes a double-gate structure for threshold voltage compensation and data input.
