Sensing layer with force sensor and touch device thereof

Abstract

The invention provides an induction layer with a force sensor and a touch device thereof. The induction layer comprises a transparent upper substrate, a transparent lower substrate, and middle parts and s edge parts of the transparent upper substrate and the transparent lower substrate; the middle parts are overlapped, and a first gap is formed between the two middle parts; the edge parts are overlapped, a second gap exists between the edge parts; a first induction line array and a first driving line array are arranged in the first gap, one or more force sensors are arranged in the second gap,and the first gap and the second gap are independently sealed and contain transparent fluid. The transparent fluid can reduce reflection and enhance transmission, so that the induction layer can quickly restore to the original state, and the loss of related parts in use is reduced. The space occupied by the device is effectively reduced, the component with the force sensing function can be arranged over the electronic device through the sensing layer, and the defect that when the force sensing device is arranged at the bottom of the electronic device, other components located above the forcesensing device need to deform in the force input process to transmit pressure to the force sensing device is overcome.

Description

technical field [0001] The present invention relates to a touch device, specifically, the present invention relates to a sensing layer with a force sensing function, and the present invention also relates to a touch device having the sensing layer. Background technique [0002] In order to realize 3D touch, the proximity object is sensed through the sensing array and driving array in the traditional touch device, such as sensing the position of the user's finger or stylus on the plane, and sensing the direction perpendicular to the panel through the force sensor pressure to achieve 3D touch sensing. This can not only sense the position of the user input, but also the force, providing an additional dimension for the diversity of input. [0003] Many existing touch screens with force-sensing functions or touchpads on notebook computers are equipped with force sensors to sense the strength of touch input commands. These force sensors are usually located on the bottom or perip...

AI Technical Summary

Problems solved by technology

Most of the existing designs with force sensors take up a lot of space, and the process of measuring force needs to be realized by the deformation of solid parts, which may cause permanent deformation or even damage of related parts during frequent or forceful use

In some existing technologies, for example, when the force sensor is installed close to the bottom or middle part of the device, the front part of the device needs to be deformed to transmit the force to the force sensor, and the parts of the front part of these devices are often not suitable for bending and extrusion, so Long-term touch use will bring adverse effects or even wear and tear on components
