  • Patent number: 12329001
    Abstract: A display panel, a detection method of a display panel, and a display device are provided. The display panel includes a display region and a non-display region surrounding the display region. The display region includes a plurality of sub-pixels and at least one first detection line. At least one sub-pixel of the plurality of sub-pixels includes at least one to-be-tested device, and the at least one to-be-tested device is electrically connected to the at least one first detection line. The non-display region includes at least one detection pad, and a detection pad of the at least one detection pad is electrically connected to a first detection line of the at least one first detection line.

  • Patent number: 12260793
    Abstract: A display panel, an electronic device and a crack detection method are provided. The display panel includes: a substrate and a detection signal line located on a side of the substrate, where the detection signal line is located in the non-display area, and includes a first detection signal line and a second detection signal line arranged in sequence in a first direction, and when detecting cracks, the first detection signal line and the second detection signal line may be used to detect cracks in different manners or in the same manner, to improve the reliability of crack detection. In addition, one of the first detection signal line and the second detection signal line may be selected for crack detection according to the actual situation, to improve the efficiency of crack detection.

  • Publication number: 20220336568
    Abstract: A display panel and a display device are provided. In an embodiment, the display panel includes a substrate; an isolating pillar; and a light-emitting functional layer. In an embodiment, the display panel has a display region, a first non-display region and a through-hole region. In an embodiment, the isolating pillar includes at least one isolating group, each of which includes a first sub-portion, and a second sub-portion. In an embodiment, the first sub-portion includes a middle portion and two end portions. In an embodiment, a cushion layer structure is disposed between the end portion and the second sub-portion, and an edge of the end portions extends beyond the cushion layer structure in the first direction to form a respective step.

  • Publication number: 20220186084
    Abstract: The present invention relates to a method for manufacturing a high temperature-resistant polyvinyl chloride adhesive tape, and more particularly to a method and a production process for manufacturing a high temperature-resistant adhesive tape by applying a UV-crosslinkable hot-melt pressure-sensitive adhesive to a high temperature-resistant polyvinyl chloride film. The high temperature-resistant polyvinyl chloride film is a high temperature-resistant material containing a liquid polymeric plasticizer, a solid polymeric plasticizer, and a heat stabilizer. The hot-melt pressure-sensitive adhesive can be directly coated onto the high temperature-resistant polyvinyl chloride film at 130-150° C.; and then crosslinked and cured by UV irradiation, to make a high temperature-resistant polyvinyl chloride adhesive tape.
