Abstract:
The present disclosure proposes an in-cell touch display panel and a gate driver on array (GOA) circuit. A pre-charging circuit is arranged on an nth stage GOA unit circuit of the GOA circuit and the in-cell touch display panel. A first node controlling signal on a first node of an (n+2)th stage GOA unit circuit is pre-charged, reducing a risk of failure of stage-by-stage signal transmitting arising from poor holding voltage of the GOA unit circuit during the signal suspending and improving reliability of the GOA circuit.
