Abstract:
A GOA circuit and an embedded touch display panel are provided. By providing an abnormity protection module in the nth-level GOA unit, the level of the scanning signal of the nth-level GOA unit is pulled up when the embedded touch display panel is powered off abnormally. The risk of abnormal display resulted from the residual of charges in pixels due to the abnormal power-off of the GOA circuit is reduced.
