This work presents a pixel circuit for the mini-LED displays. The proposed circuit compensates for V_TH variations and the VDD I-R drops to generate uniform driving currents with the current error rates less than 4.89%. Additionally, this circuit switches the voltage of the power supply line to reduce power consumption.
