  • Publication number: 20250004334
    Abstract: The present disclosure provides a display panel, including a substrate, and touch lines and touch electrodes located at one side of the substrate. One touch electrode is electrically connected to at least one touch line; each touch electrode includes at least one hollow extending along a first direction; each touch electrode is isolated by the at least one hollow in a second direction; the second direction intersects with the first direction; each touch electrode includes electrode portions respectively located at two sides of the hollow; in a region of the touch electrode, at least a part of a first touch line is in contact and electrical connection with the touch electrode; along a direction perpendicular to a plane of the substrate, a second touch line overlaps with one hollow; and electrode portions at least located at two sides of the second touch line are electrically connected through a bridging portion.

  • Publication number: 20240312392
    Abstract: A gate driving unit and a driving method for the same, a shift register circuit, and a display apparatus, and an operating period of the gate driving unit comprises a first and a second sub-period; a first pull-down node control module in the gate driving unit causes a first pull-down sub-node to be at an inactive level in the second sub-period, and causes the first pull-down sub-node to be at an active level during a reset phase in the first sub-period; a second pull-down node control module causes a second pull-down sub-node to be at an inactive level in the first sub-period, and causes the second pull-down sub-node to be at an active level during a reset phase in the second sub-period. It is possible to shorten the turn-on time of transistors controlled by the first and the second pull-down sub-nodes, and improve the reliability of the gate driving unit.
