Patent number: 12010876Abstract: Provided are a display substrate and a manufacturing method thereof, and a display device. The display substrate includes: a base substrate; a drive circuit layer formed on the base substrate and including an interlayer dielectric layer at the display region and the transition region; display parts at the display region, including a first electrode and a pixel definition portion sequentially formed on the interlayer dielectric layer; a first packaging dam and a second packaging dam at the transition region and around the opened region, each including a protective portion and a blocking portion sequentially laminated on the interlayer dielectric layer. The second packaging dam is at a side of the first packaging dam away from the display region, and a thickness of the second packaging dam is greater than that of the first packaging dam.Type: GrantFiled: March 18, 2020Date of Patent: June 11, 2024Assignees: Chengdu BOE Optoelectronics Technology Co., Ltd., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Xin Zhang, Yang Zhou, Yupeng He, Xiaofeng Jiang, Meng Zhang, Lu Bai, Yi Qu, Huijun Li, Lulu Yang, Pengfei Yu, Hao Zhang, Mengqi Wang

Patent number: 11990087Abstract: A display panel includes a first display area, a second display area, and a transition display area there-between. The first display area includes a plurality of first sub-display areas, the second display area includes a plurality of second sub-display areas, and the transition display area includes at least one sub-transition area. A first sub-display area of the plurality of first sub-display areas, a second sub-display area of the plurality of second sub-display areas and a sub-transition area include a same number of light-emitting elements. Number of pixel circuits for driving each light-emitting element in one of the at least one sub-transition area is greater than number of pixel circuits for driving each light-emitting element in one of the plurality of first sub-display areas and is smaller than number of pixel circuits for driving each light-emitting element in one of the plurality of second sub-display areas.Type: GrantFiled: August 19, 2022Date of Patent: May 21, 2024Assignee: Hubei Yangtze Industrial Innovation Center of Advanced Display Co., LTD.Inventors: Xiao Chi, Lulu Pan, Shaorong Yu

Publication number: 20240099053Abstract: A display substrate, a manufacturing method thereof, and a display device are provided. A pixel region is provided with a light emission function layer on a base substrate of the display substrate, and a separation region is provided with at least one first barrier structure. The first barrier structure includes a stopper pattern and a first separation component. A side surface of the first separation component has a recess, and a portion of the light emission function layer extending to the separation region is disconnected on the side of the first separation component. The separation region is provided with an inorganic layer structure on the base substrate. The inorganic layer structure includes multiple stacked inorganic film layers, the stopper pattern is located between two adjacent inorganic film layers and the first separation component is located on a side of the inorganic layer structure away from the base substrate.Type: ApplicationFiled: November 15, 2023Publication date: March 21, 2024Inventors: Yupeng HE, Yang ZHOU, Xin ZHANG, Pengfei YU, Xiaofeng JIANG, Yi QU, Lulu YANG, Huijun LI, Meng ZHANG
