Asynchronous High-Speed Combination Logic Circuitry using LTPS-TFT and BST for LCD Panel

In this paper, an asynchronous high-speed logic circuitry using low temperature poly silicon-thin film transistor (LTPS-TFT) and the bootstrapped technology (BST) for liquid crystal display (LCD) is proposed. The proposed logic circuit operates at high frequency region owing to the deep non-saturation operation by using the bootstrapped technology. To confirm some characteristics of the proposed circuit, an inverter and a NAND gate circuits are simulated. As the results, the power delay products are about 1/3 times less value than that of the conventional circuit under the conditions of +10 V power supply voltage and 0.5 pF load capacitor.
