    Abstract: A scan driving circuit includes a plurality of stages, each having a shift register and a scan signal output unit. The shift register has a first node to receive a first driving voltage according to a control signal and a second node to receive the first driving voltage according to a reset signal. The scan signal output unit outputs scan signals to respective scan lines. The scan signal output unit has a plurality of clock switches controlled according to a voltage of the first node and a plurality of switches controlled according to a voltage of the second node. The clock switches sequentially output clock signals to respective third nodes, which are connected to respective scan lines. The switches output a second driving voltage to the third nodes.

    Abstract translation: 扫描驱动电路包括多个级，每个级具有移位寄存器和扫描信号输出单元。 移位寄存器具有根据控制信号接收第一驱动电压的第一节点和根据复位信号接收第一驱动电压的第二节点。 扫描信号输出单元将扫描信号输出到各扫描线。 扫描信号输出单元具有根据第一节点的电压控制的多个时钟开关和根据第二节点的电压控制的多个开关。 时钟切换顺序地将时钟信号输出到相应的第三个节点，它们连接到相应的扫描线。 开关将第二驱动电压输出到第三节点。

    Abstract: A stage includes an output, an input, signal processors, and a stabilizer. The output supplies a voltage of a first or second power source to an output terminal based on voltages of first and second nodes. The input controls voltages of third and fourth nodes based on signals to a first and second input terminals. A first signal processor controls the voltage of the first node based on the voltage of the second node. A second signal processor is connected to a fifth node and controls the voltage of the first node based on a signal to a third input terminal. A third signal processor controls the voltage of the fourth node based on the voltage of the third node and the signal to the third input terminal. The stabilizer is connected between the second signal processor and input to control voltage drop widths of the third and fourth nodes.
