Abstract
The present disclosure provides a gate driver on array (GOA) circuit. A low level signal source is used to output a low level signal, a first high level signal source is used to output a first high level signal, and the second high level signal source is used to output the second high level signal. A cascade signal latch module is used to latch a cascade signal of a current grade. A gate driving signal generating module generates a preparation gate driving signal of the current grade. A gate driving signal outputting module is used to output a gate driving signal of the current grade.
