Title:
TOUCH DEVICE HAVING FORCE SENSOR
Document Type and Number:
WIPO Patent Application WO/2020/216306
Kind Code:
A1
Abstract:
A touch device having a force sensor, comprising a transparent upper substrate and a transparent lower substrate. A gap is provided between the transparent upper substrate and the transparent lower substrate, and a sensing line and a driving line are provided in the gap. One or more pressure sensors are also provided and a transparent fluid is contained in the gap. The present disclosure achieves position touch and force sensing functions by means of a novel touch structure design and wiring method. The transparent fluid can reduce reflection and enhance transmission, so as to provide a unique texture experience for users, facilitate quickly restoring a sensing layer to its original state, achieve rapid repeat input, and reduce the loss of related components in use. The present disclosure effectively reduces the space occupied by the device, and for the sensing layer, a component having force sensing function can also be disposed directly above an electronic device, so as to avoid the disadvantage that when the force sensing device is mounted at the bottom of the electronic device, other components located above the force sensing device need to be deformed during the force input process to transmit pressure to the force sensing device.
