  • Publication number: 20250347965
    Abstract: Embodiments of the present application provides a display panel and a display apparatus, the display panel comprising a plurality of first signal lines and a plurality of second signal lines, the second signal line and part of the first signal lines being insulated and crossed to define a plurality of pixel opening areas; part of the first signal lines overlapping with the pixel opening area along a thickness direction of the display panel to decrease a distance between two adjacent ones of the first signal lines and reduce the coupling interference, while reducing a shortcut between two adjacent ones of the first signal lines; the display panel further comprising a first pixel electrode overlapping with the first signal line in the thickness direction of the display panel; a width D1 of the first pixel electrode and a width D2 of any other pixel electrode satisfying |D1?D2/D1?20% along the second direction.

  • Patent number: 12462721
    Abstract: Provided are a display panel including multiple scan lines located in the display region and gate drive unit groups located in a non-display region. The gate drive unit groups include at least one first gate drive unit group and at least one second gate drive unit group. The first gate drive unit group includes multiple cascaded first gate drive units. The second gate drive unit group includes multiple cascaded second gate drive units. The first gate drive units and the second gate drive units are connected to different scan lines. A first period during which a first gate drive unit at the first stage transmits an effective level signal to a scan line and a second period during which a second gate drive unit at the first stage transmits an effective level signal to a scan line overlap, overlap duration is t, and t>0.

  • Publication number: 20250053042
    Abstract: Provided are a display panel and a display device. The display panel includes a first substrate and a second substrate disposed opposite to each other, and a liquid crystal layer located between the first substrate and the second substrate. The first substrate is provided with a planarization layer. A surface of a side of the planarization layer facing the liquid crystal layer is provided with multiple groove structures and a protrusion structure located between adjacent groove structures, the second substrate is provided with color film structures which are arranged at intervals, and a color film structure at least partially overlaps with a groove structure in a thickness direction of the display panel. Multiple first support structures are disposed between the first substrate and the second substrate, and a first support structures and the planarization layer are disposed at intervals in the thickness direction of the display panel.

  • Publication number: 20240421165
    Abstract: A display panel and a display device are provided. The display panel includes: a display region, a non-display region, and multiple drive signal lines. A fanout region and a connection terminal region are disposed in the non-display region. Multiple fanout wires are arranged in the fanout region. Multiple connection terminals are arranged in the connection terminal region. The fanout wires include a first fanout wire and a second fanout wire. The first fanout wire includes a first wire segment. The first wire segment has a width different from the width of the second fanout wire. The length of the first wire segment is equal to at least a portion of the length of the first fanout wire.
