Abstract
A shift register, includes a shift register unit and a first detection circuit electrically connected to the shift register unit. The shift register unit includes an input sub-circuit and an output sub-circuit. The input sub-circuit is configured to transmit a signal of an input signal terminal to a pull-up node under control of an input control terminal. The output sub-circuit is configured to receive a clock signal from a clock signal terminal, and provide an output signal to an output signal terminal based on the clock signal under control of a voltage at the pull-up node. The first detection circuit is electrically connected to the pull-up node and the clock signal terminal, and is configured to obtain a voltage difference at the pull-up node within a first interval time, and perform compensation on a voltage of the clock signal based on the voltage difference at the pull-up node.
