  • Publication number: 20240106262
    Abstract: An apparatus for supplying emergency power according to an embodiment of the present disclosure includes: a protection circuit unit connected to a battery and configured to limit an available voltage range of the battery; a bypass unit connected in parallel to the protection circuit unit and configured to form a bypass path of a current output from the battery according to an operation state of a disposed switching element; and a control unit configured to electrically connect the bypass path formed by the bypass unit by controlling the operation state of the switching element to a turn-on state.

  • Publication number: 20230232665
    Abstract: A light-emitting display device can include a plurality of first electrodes over a substrate; a bank to overlap an area between the first electrodes and an edge of each of the first electrodes; a bank recess in the bank at the area between the first electrodes; a hard mask pattern to partially overlap the bank recess and to abut an upper part of the bank; an organic layer on the first electrodes and the bank, the organic layer being discontinuous between an upper part of the hard mask layer pattern and the bank recess; and a second electrode. Also, the bank can include a bank lower portion having a first height under the bank recess, a bank body portion around the bank recess, the bank body portion having an acute taper with respect to the substrate, and a bank overlap portion to overlap the plurality of first electrodes.

  • Patent number: 11641766
    Abstract: A light-emitting display device includes an organic layer formed to be divided between adjacent subpixels through a change in structure of a bank without the provision of an additional construction, whereby it is possible to prevent lateral leakage of current.

  • Patent number: 11322564
    Abstract: A display device capable of reducing a non-display area includes a substrate including at least one hole area disposed within an emission area, and at least one blocking hole passing through inorganic insulating films disposed beneath a light emitting element while including upper and lower insulating films made of different materials. Side surfaces of the upper inorganic insulating film exposed through the blocking hole protrude beyond side surfaces of the lower inorganic insulating film exposed through the blocking hole, respectively. Accordingly, it is possible to minimize a bezel area, which is a non-display area, and to disconnect a light emitting stack by the blocking hole.
