Abstract: The embodiments of the present application provide a method for manufacturing thin-film transistor (TFT) substrate and a TFT substrate thereof. A semi-finished substrate has a first region, a second region, and a third region. The semiconductor layer and the insulating layer of the semi-finished substrate are patterned under the shielding of the first etching barrier layer and the second etching barrier layer having different thickness, so that only the semiconductor layer in the second region is kept and causing the thickness of the insulating layer in the first region is greater than the thickness of the insulating layer in the third region.

Abstract: A drive circuit and a control method thereof, and a storage medium are disclosed in the present disclosure. In the present disclosure, a clock signal is at a second level during an image blanking period, and a potential of a third node is reset to a low level, so that the switching transistor is subjected to a high point voltage or a high current for a shortened time, and the potential of the third node is pulled down early, thereby preventing a third switching transistor, a fourth switching transistor, a sixteenth switching transistor, and a seventeenth switching transistor from being under the action of the high voltage or the high current for a long time.
