Patent number: 10734415Abstract: Display panel and display device are provided. The display panel includes a display region; a non-display region; and a notch. Data lines are disposed in the display region. An edge of the display panel recesses toward the display region to form the notch. The display region includes a first display region and second display regions. The notch and the first display regions are disposed between two second display regions in the first direction and are adjacent in the second direction. The data lines include first data lines in each of the second display regions separated by the notch. Connection lines are disposed surrounding the at least one notch, and each connection line connects two of the first data lines in a same column and on two sides of the notch At least a portion of the connection lines includes first segments disposed in the first display region.Type: GrantFiled: April 25, 2019Date of Patent: August 4, 2020Assignee: SHANGHAI TIANMA AM-OLED CO., LTD.Inventors: Xinzhao Liu, Kaihong Huang, Min Chen, Lin Cheng, Zhuan Gao, Ciyi Gu, Jing Lv, Haoshen Wang, Qingxia Wang, Xiaoyu Wang, Zi Xu, Jiayao Yang, Qian Zhang, Peng Zhang
