Abstract
The embodiments of the present application provide a shift register and a method for driving the same. The shift register comprises: an input unit, a pull-up unit, a reset unit, a pull-down control unit, a pull-down unit and a pull-up holding unit. The input unit is configured to couple a first voltage terminal to a pull-up point. The pull-up unit is configured to couple a clock signal terminal to an output signal terminal. The reset unit is configured to couple a second voltage terminal to the pull-up point. The pull-down control unit is configured to selectively couple one of the second voltage terminal and a third voltage terminal to a pull-down point. The pull-down unit is configured to couple the second voltage terminal to the pull-up point and the output signal terminal. The pull-up holding unit is configured to couple a fourth voltage terminal to the pull-up point.
