Abstract:
In a GOA circuit and an embedded touch display panel of the present disclosure, by providing a suppression module in each of multiple levels of GOA units, when the embedded touch display panel enters a stage in which signal interruption occurs and touch scanning is performed, a second node control signal on a second node is pulled down to a constant-voltage low level. This relieves the insufficiency in retaining capability of the GOA circuit in the case of TP interruption and further decreases the risk of stage-shift failure so that this GOA circuit becomes more stable.
