Abstract

The invention provides a three-dimensional touch control signal induction module, a three-dimensional touch control panel and a three-dimensional touch control method. The three-dimensional touch control signal induction module comprises a pressure induction module; a touch sensing module; a signal detecting and processing module is connected with the pressure sensing module and the touch sensing module. According to the invention, the three-dimensional functions of human body touch recognition and pressure sensing detection can be synchronously realized, and the problems of high mass production difficulty, complex production process and high cost are solved, and the problem of measurement errors caused by extrusion of the pressure sensing module in the installation process is solved. furthermore, through the combination of deformation of the base material layer and detection of the pressure sensing module, sensing detection of the pressure in the Z direction is achieved, and compared with a force sensitive capacitor, the detectable deformation displacement is small, the dynamic working range is large, and the sensor is suitable for large-scale mass production. the problems that when Z-direction input is coped with, the dynamic working range is small, the mass production difficulty is high, and deformation residues in the panel external force applying and removing process are difficult to cope with are solved.

Description

technical field [0001] The invention relates to the technical field of touch panels, in particular to a three-dimensional touch signal sensing module, a three-dimensional touch panel and a three-dimensional touch method. Background technique [0002] With the development of intelligent technology, touch panels have been widely used, such as: smart phones, car interiors, tablet computers, household appliances, smart watches, e-readers, virtual keyboards, industrial control panels, etc. [0003] The one-dimensional input touch panel can replace the mechanical button panel. The mechanical button panel has a complex structure, short service life, and is prone to fatigue, damage and key failure. The mechanical button panel has a rigid appearance design and shape, is not easy to bend, and is difficult to waterproof. Afraid of oil pollution, the overall cost is high. Two-dimensional input touch panels further enrich human-computer interaction methods, such as touch screens, touch ...

Problems solved by technology

[0007] Chinese patent CN201810013731.8 discloses "three-dimensional projection touch control method, controller and household appliances", which generate two-dimensional coordinate values ​​(X, Y) on the upper, lower, left and right four sides of the touch panel Add a group of touch recognition functions to generate a depth coordinate value in one direction, so as to realize the input in the Z direction of the space. This Z direction input is a capacitive sensing operation such as the movement of the finger in the space above the touch panel, not the actual pressing on the touch panel. The touch action on the panel, so it is not a Z-direction touch function, which is prone to misoperation

[0010] The "three-dimensional input module" disclosed in Chinese patent CN201520772631.5 is the specific implementation of Chinese patent CN201510639990.8. The touch electrode materials in this implementation process are indium-tin oxide ITO, carbon nanotubes, graphene, nano silver wires, and metal meshes. The cost of these materials is very high. The structure has a panel layer, a first touch electrode layer, a second touch electrode layer, a first pressure-sensitive layer, and a second pressure-sensitive layer. Adhesive lamination, complex production process and high cost

There needs to be a gap between the first pressure-sensitive layer and the second pressure-sensitive layer to form a force-sensitive capacitor. It is difficult to control the consistency of this gap in production, and it is difficult to mass produce.

[0011] In addition, the existing three-dimensional touch panel technology does not have a good solution to the deformation residue in the process of applying external force and removing the panel.
