Patent number: 11561636Abstract: A touch input device capable of detecting a pressure of a touch on a touch surface may be provided. The touch input device includes: a display panel; a substrate disposed under the display panel; and a pressure sensing unit. The pressure sensing unit includes a pressure sensor and a reference pressure sensor. When a pressure is applied to the touch surface, the display panel is bent. Electrical characteristics detected at the pressure sensor change by the bending of the display panel. A magnitude of the pressure applied to the touch surface is calculated based on a difference between a reference electrical characteristic calculated from electrical characteristics detected at the reference pressure sensor and the detected electrical characteristic calculated from the electrical characteristics detected at the pressure sensor.Type: GrantFiled: November 24, 2016Date of Patent: January 24, 2023Inventors: Bong Jin Seo, Bon Kee Kim, Myung Jun Jin, Tae Hun Kim

Publication number: 20210072862Abstract: A touch input device capable of detecting touch pressure according to an embodiment of the present invention includes a display module and a pressure sensor layer disposed on a lower portion of the display module, wherein an adhesive layer is present between the display module and the pressure sensor layer to adhere the pressure sensor layer to the display module, and the pressure sensor layer includes a structure in which a first strain gauge is formed on an upper surface of a substrate and a second strain gauge is formed on a lower surface of the substrate. When pressure is applied to the display module, the display module is bent, the electrical properties of each of the first strain gauge and the second strain gauge are changed as the display module is bent, and the Young's Modulus of the substrate is greater than the Young's Modulus of the adhesive layer.Type: ApplicationFiled: September 4, 2018Publication date: March 11, 2021Applicant: HiDeep Inc.Inventors: In Uk JEONG, Gi Duk KIM, Hyoung Wook WOO, Tae Hoon KIM, Bong Jin SEO

Patent number: 10775943Abstract: A touch input device capable of detecting a pressure of a touch on a touch surface may be provided that includes: a display module; and a pressure sensor which is disposed at a position where a distance between the pressure sensor and a reference potential layer is changeable according to the touch on the touch surface. The distance is changeable according to a pressure magnitude of the touch. The pressure sensor outputs a signal including information on a capacitance which is changed according to the distance. The pressure sensor includes a plurality of electrodes to form a plurality of channels. The pressure magnitude of the touch is detected on the basis of a change amount of the capacitance detected in each of the channels. According to the embodiment of the present invention, it is possible to provide a pressure sensor for pressure detection, a touch input device including the same, and a pressure detection method using the same.Type: GrantFiled: April 5, 2016Date of Patent: September 15, 2020Assignee: HiDeep Inc.Inventors: Bong Jin Seo, Jae Bum Jun, Hwan Hee Lee, Bon Kee Kim, Sang Sic Yoon, Myung Jun Jin
