High-speed logic circuitry used bootstrapped technology and low-temperature poly-silicon technology for TFT-LCD panel

Abstract

In this paper, a high-speed logic circuitry used bootstrapped technology and Low Temperature Poly Silicon (LTPS) technology for TFT- LCD panel is proposed. The high-speed logic circuitry realizes the high-speed operation due to applying the wider swing-voltage than the power-supply voltage by using the bootstrapped technology. As the results, the new logic circuitry can operate at the operational frequency by around 10 times than the conventional circuitry under the conditions of 0.5pF load-capacitor and +1OV power-supply voltages.
