Patent number: 10691921Abstract: A display device comprises a display panel configured to display an image. A fingerprint sensor is under the display panel and is configured to sense a fingerprint. An impact mitigating layer partially surrounds the fingerprint sensor and is configured to absorb impacts or pressure to the display device. A shielding layer is between the display panel and the fingerprint sensor and the impact mitigating layer. The shielding layer blocks at least one of heat, electromagnetic interference, or light.Type: GrantFiled: August 21, 2018Date of Patent: June 23, 2020Assignee: LG Display Co., Ltd.Inventors: DooWon Seo, HeungJu Jo, SangHyun Kwon, EuiJun Lee, YongBeom Jeong, JeongKweon Park

Patent number: 10359871Abstract: Provided is a display panel including a loop-shaped conductive path which is manufactured by performing a conductive ink jetting process and a high-degree vacuum removal process to effectively vaporizing a solvent in a conductive ink line at lower temperature than the boiling point at atmospheric pressure of the solvent. The conductive path manufactured as such does not allow a stain or a trace, such as a pull-back region, to be left around the conductive path. Thus, it is possible to obtain the loop-shaped conductive path having an initially intended design without being damaged during a process.Type: GrantFiled: August 26, 2015Date of Patent: July 23, 2019Assignee: LG DISPLAY CO., LTD.Inventors: Sunbae Kong, JeongKweon Park, Chan Park, KyengBaek Ryu, Heungju Jo
