A New Pulse Tunable IGZO TFT Shift Register for AMOLED

We proposed a new shift register based on amorphous Indium-Gallium-Zinc Oxide (IGZO) TFTs for Active-Matrix Organic Light Emitting Diode (AMOLED) with complementary function. The proposed circuit could steadily output wide pulse and the width can be modulated for threshold voltage compensation which is expected to be applied in high quality AMOLED display. The stability of the circuit has been examined by operating in high temperature and humidity condition exceed 1000 h.
