Patent number: 11088352Abstract: A display substrate, a manufacturing method thereof, and a display device are provided, in the field of display technology. The display substrate includes a base substrate, and a thin-film transistor, a light-emitting device, an encapsulation structure, and a conductive film layer sequentially disposed on the base substrate in a direction away from the base substrate. Since the display substrate includes a conductive film layer on a side of the encapsulation structure away from the base substrate, when the protective film layer on the side of the conductive film layer away from the base substrate is peeled off, static electricity generated by the separation of the film layer can be released to the conductive film layer, avoiding electron transition to the active layer of the thin-film transistor in the display substrate to cause offset of the threshold voltage of the thin-film transistor. The display brightness uniformity of the display substrate can be ensured.Type: GrantFiled: June 3, 2019Date of Patent: August 10, 2021Assignee: BOE Technology Group Co., Ltd.Inventors: Wenqu Liu, Feng Zhang, Qi Yao, Zhijun Lv, Liwen Dong, Shizheng Zhang, Ning Dang, Xiaoxin Song, Zhao Cui

Patent number: 10644270Abstract: An OLED display panel and a method for manufacturing the same are provided. By successively forming a first organic film layer, a metal film layer, and a second organic film layer on a substrate layer, a width of the metal film layer is greater than a width of the first organic film layer in a peripheral region of the OLED display panel, to form an inverted trapezoid-shaped bottom-cut structure. An included angle between an edge of the first organic film layer and the metal film layer is relatively large, and if an inorganic film layer is further formed subsequently, the inorganic film layer may have a relatively small thickness at this position, which makes it easier for a crack to occur and a fracture to appear, as such, when cutting is performed using a laser, splitting of the inorganic film layer will be terminated at this position.Type: GrantFiled: October 11, 2018Date of Patent: May 5, 2020Assignee: BOE TECHNOLOGY GROUP CO., LTD.Inventors: Zhijun L V, Feng Zhang, Shizheng Zhang, Ning Dang, Liwen Dong, Wenqu Liu
