Abstract
A shift register (SR) includes a voltage control circuit () and a bias compensation circuit (). The voltage control circuit () is configured to control a voltage at a first node (Output) to be a first voltage or a second voltage. The bias compensation circuit () is configured to: when the voltage at the first node (Output) is the first voltage, transmit a first signal received by a first signal terminal (VDD-A) to a first signal output terminal (EM), and transmit a second signal received by a second signal terminal (VDD-B) to a second signal output terminal (EM); and in response to the voltage at the first node (Output) being the second voltage, transmit a signal received by a first voltage terminal (LVGL) to the first signal output terminal (EM) and the second signal output terminal (EM).
