A fast current‐mode driving method using current feedback for AMOLED displays is proposed. The proposed driving method dramatically enhanced the driving speed by two negative feedback loops. The loop stability was also guaranteed by the proposed compensation technique and confirmed by simulations. The time to transfer the input current to the pixel current was below 10 usec with sub‐nA accuracy for the parasitic loads of 1.5kΩ resistance and 100pF capacitance in data lines.
