Problems solved by technology

However, in the process of realizing the present invention, the inventors found the following problems in the prior art: most of the existing fingerprint recognition devices do not have the function of pressure sensing, and the functions realized are relatively single; the only fingerprint recognition device with pressure sensing function The device is still based on capacitive technology, and the cost and structure requirements are relatively high
In addition, when the existing fingerprint identification device is applied to a smart terminal, it is equipped with a dome, so it is necessary to dig a through hole on the transparent cover corresponding to the position of the fingerprint identification device, so that the fingerprint identification device and the transparent cover are movable. This results in a gap between the fingerprint identification device and the through hole, which is not conducive to waterproofing

Abstract

The embodiment of the present invention relates to the technical field of electronic products, and discloses an electronic device, a fingerprint identification device and a function activation method. In the embodiment of the present invention, the fingerprint identification device includes: a flexible circuit board FPC, a fingerprint identification chip, and a pressure sensing layer; the FPC includes a first wiring layer and a second wiring layer; the bottom surface of the fingerprint identification chip is fixed on the The first wiring layer; the bottom surface of the pressure sensing layer is fixed to the second wiring layer; wherein, when the FPC is in a bent state, the top surface of the pressure sensing layer corresponds to the fingerprint Identify the underside of the chip. The embodiment of the present invention also provides an electronic device and a function activation method; the embodiment of the present invention integrates the fingerprint identification chip and the pressure-sensing layer, so that the fingerprint identification device has a pressure-sensing function, and realizes the diversification of functions of the fingerprint identification device, and The space and materials are saved, and the structure is simple, which brings convenience to manufacturing.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic products, and in particular to an electronic device, a fingerprint identification device and a method for starting a function. Background technique [0002] Existing smart terminals such as mobile phones and tablet computers are widely used in people's daily life. Due to the portability and appearance requirements of smart terminals, the structural space is very limited. People have been committed to realizing more functions in a limited space. , to give users a better experience. Wherein, the fingerprint recognition device in the smart terminal enables the smart terminal to have a fingerprint recognition function, which provides convenience for people's life. [0003] A fingerprint identification device in an existing intelligent terminal has a fingerprint identification function. However, in the process of realizing the present invention, the inventors found the fo...
