Publication number: 20230361132Abstract: 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.Type: ApplicationFiled: January 20, 2021Publication date: November 9, 2023Inventors: Le GAO, Liman PENG, Hongyu MI, Qianqian ZHANG, Xiaofeng YAN, Lingling MA, Zhiyong XUE

Patent number: 11489139Abstract: 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.Type: GrantFiled: March 23, 2021Date of Patent: November 1, 2022Assignees: Ordos Yuansheng Optoelectronics Co., Ltd., Beijing BOE Technology Development Co., Ltd.Inventors: Xiaofeng Yan, Liangliang Liu, Liman Peng, Lingling Ma, Hongyu Mi, Le Gao
