Abstract
A gate driver on array (GOA) circuit of the present disclosure includes a current leakage limiting module. The current leakage limiting module limits current leakage of a first node to maintain a high level of the first node when an embedded touch display panel enters a stage in which signal interruption occurs and touch scanning is performed, further reducing risk of cascade failure and making the GOA circuit stable.
