  • Publication number: 20230352455
    Abstract: A display device includes a substrate including a plurality of pixel areas; and a pixel provided in each of the pixel areas. The pixel may include a first electrode and a second electrode extending in a first direction on the substrate and spaced from each other in a second direction different from the first direction; a bank pattern between the substrate and the first electrode and between the substrate and the second electrode, and including at least two sub-bank patterns in a same column and spaced from each other; and a plurality of light emitting elements between the first and second electrodes. Here, each of the first and second electrodes may have at least two or more widths in the second direction along the first direction.

  • Patent number: 5251892
    Abstract: A paper ejecting apparatus embodied in a printing system, such as a video color printer, that is constructed to push out or eject a printed sheet of paper. The apparatus includes long guide channels formed in a panel for feeding paper toward an ejecting direction, a pusher movable along the guide channels, a rack gear member connected to the pusher, a guide support member for movably supporting the rack gear member, and a driving source for driving the rack gear member having a pinion driven by the driving source. Also, components are added to the driving source for preventing overload thereof. The operation of the apparatus is smooth, so that the paper is securely ejected without being damaged, and the apparatus is simple in structure and causes little mechanical noise.
