Abstract
A shift register is provided to include: a voltage regulating circuit to adjust voltages at first and second nodes; a light-emitting cascade output circuit to write a second operating voltage to a light-emitting cascade signal output terminal in response to the voltage at the first node, and write a first operating voltage to the light-emitting cascade signal output terminal in response to the voltage at the second node; a light-emitting driving output circuit to write a third operating voltage to a light-emitting control driving signal output terminal in response to the voltage at the first node, and write a fifth operating voltage to the light-emitting control driving signal output terminal in response to the voltage at the second node; and a first anti-leakage circuit to write a fourth operating voltage to a first anti-leakage node in response to the voltage at the second node.
