In this paper, pulse width modulation driving micro light-emitting diode pixel circuit using oxide TFTs, and its operations in simultaneous and progressive emission are introduced. In addition, various operation methods, the SWEEP signal generation method based on linear charging of the capacitor and inverter-based PWM driving, are suggested and discussed.
