  • Publication number: 20240120580
    Abstract: A sealing device for a pouch-type battery includes an upper sealing block and a lower sealing block. The upper sealing block has a two-stage upper sealing groove, including a first upper step and a second upper step, and the lower sealing block has a two-stage lower sealing groove, including a first lower step and a second lower step. The upper sealing block contacts a first surface of an electrode lead sealing part of the pouch-type battery, and the lower sealing block contacts a second surface of the electrode lead sealing part of the pouch-type battery in a process of performing sealing through heat fusion. A pouch-type battery having an electrode lead sealing part formed by the sealing device is also provided.

  • Patent number: 9905588
    Abstract: A display panel and a method for manufacturing the display panel are discussed. The display panel includes a substrate; an active layer on the substrate; and a passivation layer on the active layer, wherein the active layer includes a channel part, a first electrode connection part and a second electrode connection part on opposite sides of the channel part in a first direction, and a first taper part and a second taper part on opposite sides of the channel part in a second direction crossing the first direction, and wherein a carrier concentration of each of the first taper part and the second taper part is different from those of the channel part, the first electrode connection part and the second electrode connection part.
