Abstract

The invention relates to the technology of pressure detection, and discloses a touch pressure detection apparatus. The touch pressure detection apparatus comprises a cover plate, a fingerprint recognition module and pressure sensing assemblies, the pressure sensing assemblies and the fingerprint recognition module are arranged under the cover plate, the pressure sensing assemblies are arranged adjacent to the fingerprint recognition module, each pressure sensing assembly comprises a first substrate and a second substrate arranged in an opposite manner, and a variable gap is arranged between the first substrate and the second substrate. When the fingerprint recognition module is pressed by an external pressure, the pressure is transmitted to the pressure sensing module so that the variable gap between the first substrate and the second substrate is changed due to pressure.

Description

technical field [0001] The present application belongs to the technical field of pressure detection, and in particular relates to a touch pressure detection module and device. Background technique [0002] Traditional touch screen mobile phones usually use virtual keys based on capacitive touch technology. The working principle of the virtual key based on capacitive touch technology is that when a finger touches the key area, the finger causes the electric field change of the sensing electrode under the key area panel, and the electric field change is converted into a current / voltage signal change, which is then sensed and responded by the mobile phone. [0003] In the process of realizing the present invention, the inventor found that the problems of the above technologies are very prone to misuse, for example: 1. When the finger touches the button unconsciously, the button responds; Press the key, and the key will respond. In the above scenarios, the user is not willing ...
