  • Patent number: 10916177
    Abstract: A display apparatus in which each unit pixel includes four sub-pixels is provided. The four sub-pixels of each unit pixel may sequentially receive a data line through single data line. Two sub-pixels disposed on a side of the data line may be connected to a reference voltage supply line by a reference connecting line intersecting the data line. Two sub-pixels disposed another side of the data line may be connected to the data line by a data connection line intersecting the reference voltage supply line. An intersection region of the reference connection line and the data line may have the same area as an intersection region of the data connection line and the reference voltage supply line. Thus, in the display apparatus, the variation in the charging rate due to the parasitic capacitance difference of the data connection line and the reference connection line may be reduced.

    Abstract: A memory system includes a storage device including a nonvolatile memory device and a storage controller configured to control the nonvolatile memory device, and a host that accesses the storage device. The storage device transfers map data, in which a physical address of the nonvolatile memory device and a logical address provided from the host are mapped, to the host depending on a request of the host. The host stores and manages the transferred map data as map cache data. The map cache data are managed depending on a priority that is determined based on a corresponding area of the nonvolatile memory device.

  • Publication number: 20210028464
    Abstract: A battery having an electrode assembly comprising a cathode having a cathode collector coated, partially or entirely, with a cathode active material, an anode having a nano-web layer on both sides of an anode collector coated, partially or entirely, with an anode active material, and a separation membrane interposed between the cathode and the anode; an electrolytic solution; and an exterior material which encapsulates the electrolyte solution and the electrode assembly together. Since the battery has a porous nano-web layer, even if the temperature inside the battery increases to cause shrinkage or melting of the separation membrane, a contact between the cathode and the anode is prevented such that ignition and/or explosion of the battery does not occur, ion exchange is not disturbed such that the battery performance does not deteriorate, and the nano-web layer is not molten or released towards the separation membrane even at high temperatures.

  • Patent number: 10899642
    Abstract: The present invention relates to a wastewater treatment apparatus for shortcut nitrogen removal using anaerobic ammonium oxidation (ANAMMOX) and partial nitritation using ammonium oxidizing bacteria (AOB) granules. High-purity AOB granules are formed by means of AOB predominance using a side stream generated during a sludge treatment process. Moreover, the formed AOB granules are supplied to a partial nitritation tank (130) of a main treatment process and thus the partial nitritation is efficiently performed and nitrogen is quickly removed, and thus oxygen and an organic material is reduced compared to an existing method.
