  • Publication number: 20240172501
    Abstract: A display panel in one example includes a substrate, an anode including an emission region on the substrate, a reference voltage line adjacent to the anode, and a branch line connected to the reference voltage line to apply a reference voltage from the reference voltage line to the anode via a switching element. The branch line includes a semiconductor layer, and the branch line is between the reference voltage line and the anode.

  • Publication number: 20240154118
    Abstract: Cathode active materials for lithium secondary batteries and lithium secondary batteries including the cathode active materials are disclosed. In some implementations, a cathode active material for a lithium secondary battery includes a lithium metal phosphate particle having a crystallite size in a range from 150 nm to 450 nm in a direction of a crystallographic plane (020) as measured by an X-ray diffraction (XRD) analysis. In some implementations, a lithium secondary battery includes a cathode including a cathode active material layer that includes a cathode active material for a lithium secondary battery, and an anode facing the cathode. In some implementations, an electrode crystallite size ratio defined by Equation 4 is in a range from 0.5 to 0.9.

  • Publication number: 20240099103
    Abstract: A display device includes a display area, a peripheral area disposed outside the display area, and a sealing area disposed outside the peripheral area, a first base substrate, a second base substrate facing the first base substrate, a color filter layer disposed under the first base substrate, a bank layer disposed under the color filter layer, and a sealing member disposed between the bank layer and the second base substrate in the sealing area. The bank layer includes bank patterns defining an opening disposed at least in the sealing area, and the sealing member fills the opening. Each of the bank patterns includes a first surface adjacent to the color filter layer and a second surface opposite to the first surface and adjacent to the sealing member. A width of the second surface is greater than a width of the first surface.

  • Patent number: 11925084
    Abstract: A display panel can include a substrate, a light-emitting element including an emission region on the substrate, a reference voltage line adjacent to the light-emitting element, and a branch line connected to the reference voltage line to apply a reference voltage to light-emitting element. The light-emitting element can emit light on the emission region in a direction of the substrate. Further, the branch line can include a semiconductor layer, and the semiconductor layer of the branch line can overlap the emission region.

  • Patent number: 10865886
    Abstract: A pressure control valve may include a valve body, a fixed cylinder and a rotating cylinder. The valve body may have an inlet port and an outlet port. The fixed cylinder may be fixed to an inner wall of the valve body. The fixed cylinder may include a quadrangular first fixed hole connected to the inlet port, and a quadrangular second fixed hole connected to the outlet port. The rotating cylinder may be rotatably arranged in the fixed cylinder. The rotating cylinder may include a quadrangular first pressure control hole selectively connected to the first fixed hole, and a quadrangular second pressure control hole selectively connected to the second fixed hole. Thus, the pressure control valve including the quadrangular fixed hole and the quadrangular pressure control hole may have improved pressure control function.
