  • Patent number: 12002434
    Abstract: The present embodiment provides a GOA circuit and a display panel, in which the GOA circuit comprises a forward/backward scanning control module, an output module, a potential regulation module, a node control module, and a voltage stabilizer module. A first node and a third node are not conducted when a second node is at a second potential; the first node and the third node are conducted and have a second potential when the second node is at a third potential, wherein the second potential is opposite to the third potential. Thus, GOA circuit's leakage issue existing in the TP suspension stage can be improved.

  • Patent number: 11710436
    Abstract: The present application provides a GOA circuit and a display panel. In the GOA circuit, one of two GOA units of a same stage in GOA sub circuits at left and right sides of the display panel is deployed only with an all-on module and the other one of the two GOA units is deployed only with an all-off module. In such a way, both the number of the all-on modules and the number of the all-off modules required in the GOA unit are halved, thereby reducing the area occupied by the GOA circuit. It is beneficial for realizing a display panel with a narrow bezel.

  • Patent number: 8288124
    Abstract: The present invention relates to a new method of producing functionally active recombinant porcine Intrinsic Factor as well as the protein (i.e., porcine Intrinsic Factor) produced thereby. In particular, the vector comprising the DNA encoding the protein is introduced into a Chinese Hamster Ovary (CHO) host cell under conditions sufficient for optimal expression of functional protein. The expressed protein may then be subjected to three methods ultimately resulting in a protein having at least 97% purity.
