    摘要: Disclosed is a logic gate and a scan driver capable of being realized with MOS transistors of a single polarity type only, preferably PMOS transistors. The logic gate comprises a plurality of input terminals (IN1-IN3), a first driver (10), a second driver (12), a third driver (14), a control transistors (M8), a first capacitor (C2), and a fourth driver (16). The first driver (12) is adapted to provide a first power supply voltage (VDD) to a first node (N1) corresponding to a logic combination of the plurality of input signals and the second driver (14) is adapted to provide a second power supply voltage (VSS) to the first node (N1) when the first driver (12) does not provide the first power supply voltage (VDD) to the first node (N1). The third driver (14) is adapted to provide the first power supply voltage (VDD) to an output terminal of the logic gate when the second power supply voltage (VSS) is provided to the first node (N1) and the fourth driver (16) is adapted to provide the second power supply voltage (VSS) to the gate electrode of the control transistor (M8) when the third driver (14) does not provide the first power supply voltage (VDD) to the output terminal. Each of the first driver (10), the second driver (12), the third driver (14), and the fourth driver (16) comprises at least one transistor. These transistors and the control transistor are MOS transistors of the same polarity type.
