  • Electronic device
    Patent number: 10860129
    Abstract: An electronic device comprises a base substrate changing a cross section area corresponding to an external force applied from outside and a sensor changing a cross section area corresponding to the external force applied from outside. The sensor comprises a first electrode disposed on the base substrate, a second electrode disposed on the base substrate, and a dielectric layer disposed between the first electrode and the second electrode. A thickness of the dielectric layer stays substantially the same when a cross sectional area of the base substrate changes.
    Type: Grant
    Filed: January 4, 2018
    Date of Patent: December 8, 2020
    Assignees: Samsung Display Co., Ltd., Research Business Foundation SUNGKYUNKWAN UNIVERSITY
