N2 - We have designed an integrated a-IGZO TFT-based Vcom driver circuit with low power consumption, narrow bezel and long-term reliability on a glass substrate. The proposed driving scheme can achieve 40% lower power consumption than the conventional driving scheme, owing to Vcom inversion. The higher mobility (> 10 cm 2 / V.s) of the a-IGZO TFTs compared to a-Si:H TFTs allows the integration of smaller size devices in the gate driver circuitry, leading to displays with narrower bezels. AC driving of the buffer TFTs by clocking the n th and (n+1) th frame with 20 and 0 V, respectively, improves the lifetime of the Vcom driver circuit.
