Abstract
The present disclosure provides a gate drive circuit, an array substrate, and a display device. The gate drive circuit includes cascaded shift registers, control circuits, level shifters, voltage stabilization circuits, and first exchanging circuits. The shift registers at respective stages output respective first signals. Each control circuit is configured to process the respective first signal to generate a respective second signal. Each level shifter is configured to convert the voltage level of the respective second signal to generate a respective third signal. Each voltage stabilization circuit is configured to stabilize the respective third signal. The stabilized third signal is outputted as a fourth signal. The first exchanging circuit is configured to enable any of the following: exchanging the first signals at two adjacent stages, exchanging the second signals at two adjacent stages, exchanging the third signals at two adjacent stages, and exchanging the fourth signals at two adjacent stages.
