Abstract
A high-speed and reliable TFT integrated shift register for high-resolution display is proposed. By inhibiting the leakage current in pull-up period and enhancing the discharge ability of driving TFT in pull-down period, the operating frequency is improved by 49%. Besides, the proposed circuit is expected to have high reliability due to the lowered gate voltages on the critical TFTs biased through capacitor coupling.
