Abstract
A gate driver on array (GOA) circuit includes a first GOA unit. The first GOA circuit includes a first pull-up control module that includes a first transistor, having a gate receiving a control signal, a source receiving a starting signal, and a drain electrically connected to a first node. When the first transistor is turned off, a voltage level of the gate of the first transistor is lower than a voltage level of the source; the source of the first transistor is an end for signal inputting; and the drain of the first transistor is an end for signal outputting.
