Abstract
A GOA circuit includes GOA circuit units. Each GOA circuit has a holding module A first transistor and a second transistor in the holding module holds the voltage imposed on the first control node to be at high voltage level. Also, the transistors form a direct current passage between the first control node and a first fixed voltage at high voltage level so the voltage imposed on the first control node is not lowered due to electricity leakage. The GOA circuit unit can resolve the problem of easy leakage of electricity. When the scanning signals are output by the GOA circuit unit, the stability is highly ensured.
