We propose a new integrated a‐Si Gate Driver for Advanced In‐cell Touch(AIT). When the frame period divide in the display period and the touch period, abnormal gate signal due to the Q‐node discharging during the touch period make the horizontal dim line in panel. The proposed gate driver improves the Q‐node discharging during the touch period. We have succeeded in developing the gate driver circuit for advanced in‐cell touch panel which is 12.5inch FHD for notebook.
