We propose a mask reduction process using triple‐metal TFT source‐drain layers by removing the protective pad layer. In this process flow, an innovative undercut structure is fabricated, which could successfully contact the auxiliary electrodes with topemission OLED cathode to reduce IR‐drop in large size AMOLED display.
