    • A gate shift register and a display device using the same are disclosed. The gate shift register includes a plurality of stages that receive a plurality of gate shift clocks and sequentially output a scan pulse. A k-th stage of the plurality of stages includes a scan direction controller for converting a shift direction of the scan pulse in response to carry signals of previous stages input through first and second input terminals and carry signals of next stages input through third and fourth input terminals, a node controller for controlling charging and discharge operations of each of Q1, Q2, QB1, and QB2 nodes, a floating prevention unit for applying a low potential voltage to a gate electrode of a discharge TFT based on a voltage of the QB1 node or the QB2 node, and an output unit for outputting first and second scan pulses.
    • 公开了一种门移位寄存器和使用其的显示装置。 栅极移位寄存器包括接收多个栅极移位时钟并顺序地输出扫描脉冲的多个级。 多级的第k级包括扫描方向控制器,用于响应于通过第一和第二输入端输入的先前级的进位信号来转换扫描脉冲的移位方向,并且传送通过第三和第四输入的下一级输入信号 输入端子,用于控制Q1,Q2,QB1和QB2节点中的每一个的充电和放电操作的节点控制器,用于基于QB1的电压向放电TFT的栅电极施加低电位电压的浮动防止单元 节点或QB2节点,以及用于输出第一和第二扫描脉冲的输出单元。
