  • Publication number: 20260016723
    Abstract: A display panel and a display device are provided. The display panel includes: an opposite substrate and a display substrate arranged opposite to each other, and multiple support pillars between the opposite substrate and the display substrate. The display substrate includes a display area and a non-display area surrounding the display area. The non-display area includes a first wiring area. The multiple support pillars include first support pillars in the display area and second support pillars in the non-display area. Partial support pillars corresponding to the first wiring area among the second support pillars extend in a direction perpendicular to an extending direction of the side edge of the first wiring area.

  • Publication number: 20250393304
    Abstract: A display substrate includes a display area and a non-display area surrounding the display area. The non-display area includes a fan-shaped area between the display area and a side edge of the display substrate. The fan-shaped area includes: multiple first wiring lines extending along a direction parallel to an extending direction of the side edge, and multiple second wiring lines extending along a direction perpendicular to the extending direction. The multiple first wiring lines and the multiple second wiring lines are interconnected to form multiple grid units. In each grid unit, a first distance between two first wiring lines and a second distance between two second wiring lines are both less than a preset value.

  • Publication number: 20250164840
    Abstract: A display substrate includes a base substrate, first electrodes arranged in an array on the base substrate, a first signal line, a second signal line crosswise arranged with the first signal line, and a pattern layer arranged at a same layer and made of a same material as the first electrode. An orthographic projection of the pattern layer on the base substrate does not overlap an orthographic projection of the first signal lines on the base substrate. The first electrode comprises a first strip electrode. An extension direction of the first strip electrode is intersected with a row direction and a column direction.

  • Patent number: 12216364
    Abstract: The present disclosure provides a display substrate, a manufacturing method of the display substrate and a display apparatus. The display substrate includes a base substrate; an alignment layer, on the base substrate; a first electrode, located between the base substrate and the alignment layer and being in contact with the alignment layer; and a pattern layer, located between the base substrate and the alignment layer and being in contact with the alignment layer. An orthographic projection of the pattern layer on the base substrate does not overlap an orthographic projection of the first electrode on the base substrate, and a ratio of a contact angle of the pattern layer to a contact angle of the first electrode is greater than or equal to 7/12 and less than 3/2.

  • Patent number: 12189250
    Abstract: Embodiments of the present disclosure provide a display substrate having a display region and a frame region. The display substrate includes a plurality of display pixels and a plurality of dummy pixels arranged in an array; the display pixels are distributed in the display region; the dummy pixels are distributed in the frame region. Each display pixel includes a first pixel electrode and a first common electrode; and a first voltage difference exists between the first pixel electrode and the first common electrode. Each dummy pixel includes a second pixel electrode and a second common electrode; and a second voltage difference exists between the second pixel electrode and the second common electrode. A difference between the first voltage difference and the second voltage difference is less than a set value. Embodiments of the present disclosure further provides a display panel and a display apparatus.
