  • Publication number: 20250077010
    Abstract: A display panel and a display device, including scan lines and data lines intersecting each other to define sub-pixel regions. At least one sub-pixel is provided in a respective sub-pixel region and includes a first electrode including two domain portions having different domain orientations along extending direction of the scan line. Extending direction of the touch line is the same as that of the domain boundaries of a column of first electrodes, and a vertical projection of the touch line overlaps with a vertical projection of the domain boundaries of a column of first electrodes onto the substrate. The touch electrode is electrically connected to the touch line via a first through-hole arranged adjacent to the scan line, and a vertical projection of the first through-hole overlaps with a vertical projection of the touch line onto the substrate. The display and touch effect of the display panel is improved.

  • Publication number: 20250046225
    Abstract: Provided display panel includes a first drive circuit including multiple shift registers. At least one shift register is a first-type shift register including pull-up unit, voltage storage unit, and first output unit. The pull-up unit is connected to first trigger terminal, first signal terminal, and first node. The voltage storage unit is connected to the first node, first clock terminal, second signal terminal, third signal terminal, fourth signal terminal, and second node. The first output unit is connected to the second node, the first clock terminal, and output terminal. During normal display scanning drive of the display panel, the display scanning drive can be interrupted when scanning to the first-type shift register, and the touch drive can be inserted and executed to realize the intra-frame touch drive which does not need to compress display time of one frame, has higher touch flexibility, facilitates improving touch effect and touch performance.

  • 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.
