  • Publication number: 20230361132
    Abstract: A display substrate includes an underlay substrate, a test signal access pin layer, and a signal access pin layer. The underlay substrate includes a display region and a border region at a periphery of the display region. The border region includes a signal access region at one side of the display region and at least one test signal access region adjacent to the signal access region. The test signal access pin layer is in the at least one test signal access region. The signal access pin layer is in the signal access region. A height difference between a surface of the test signal access pin layer away from the underlay substrate and a surface of the signal access pin layer away from the underlay substrate is greater than 0.

  • Patent number: 11688746
    Abstract: A method for preparing an array substrate, a display panel and an evaporation apparatus are disclosed. A method comprises: fixing a base substrate to an evaporation stage; attaching at least one shielding sheet to the base substrate to cover at least a preset area of the base substrate; arranging and aligning an open mask in association with the base substrate, wherein the open mask has at least one opening for vapor deposition, and the at least one shielding sheet is positioned corresponding to the at least one opening and each has an area that is less than an area of a corresponding opening to shield a portion of the corresponding opening, and wherein the portion of the corresponding opening is separate from a boundary of the corresponding opening; and evaporating to form an evaporation material layer on the base substrate, to which the shielding sheet is attached.

  • Patent number: 11489139
    Abstract: Provided are a display panel, a preparation method thereof and a display apparatus. The display panel includes a display substrate and a cover plate oppositely disposed. The display substrate includes an array substrate, pixel define layers on the array substrate, pixel support layers on a side of the pixel define layers away from the array substrate, and second electrodes each located on a side of each of the pixel support layers away from each pixel define layers. The cover plate includes a first substrate, a touch sensor layer and protective layer disposed on the first substrate, wherein multiple openings are disposed on the touch sensor layer and covered by the protective layer. An orthographic projection of each of the openings on the array substrate at least partially overlaps with that of a surface on a side of each of the pixel support layers away from the array substrate.
