1. A gate driver on array (GOA) circuit, comprising:
a first GOA sub circuit disposed at one side of a display panel;
a second GOA sub circuit disposed at another side of the display panel; and
a plurality of cascaded GOA units disposed in the first GOA sub circuit and the second GOA sub circuit, wherein two GOA units of a same stage in the first GOA sub circuit and the second GOA sub circuit jointly drive a same scan line,
wherein one of the two GOA units of a same stage comprises one of an all-on module and an all-off module, and the other one of the two GOA units comprises the other one of the all-on module and the all-off module, and
wherein the all-on module is configured to simultaneously switch on thin-film transistors of all pixels connected to the scan line, and the all-off module is configured to simultaneously switch off the thin-film transistors of all the pixels connected to the scan line, and
wherein one of two cascaded GOA units in the first GOA sub circuit or the second GOA sub circuit only comprises the all-on module, and the other one of the two cascaded GOA units only comprises the all-off module.
