Abstract: A gate-on-array (GOA) driving circuit is provided, and the GOA driving circuit includes a plurality of cascading GOA driving units. Each of the GOA driving units further includes a first GOA driving sub-unit including a first signal source and a second GOA driving sub-unit including a second signal source. The first GOA driving sub-unit operates when the first signal source transmits a first signal with a high voltage, and the second GOA driving sub-unit transmitting a second signal operates when the first signal source transmits the first signal with a low voltage.
