Abstract

The invention discloses a fingerprint detector. The fingerprint detector comprises a power supply assembly, a capacitance type fingerprint sensor, a microcontroller and a signal processor, wherein the power supply assembly is electrically connected with the capacitance type fingerprint sensor, the microcontroller and the signal processor respectively; the microcontroller is connected with one end of the capacitance type fingerprint sensor, and the signal processor is connected with the other end of the capacitance type fingerprint sensor; the capacitance type fingerprint sensor comprises a plurality of sensing units arranged in an array manner and used for acquiring fingerprint information and transmitting the fingerprint information to the signal processor; the signal processor is used for processing the fingerprint information; the microcontroller is used for controlling the capacitance type fingerprint sensor and the signal processor according to the processing result of the signal processor. According to the fingerprint detector disclosed by the invention, when the capacitance type fingerprint sensor acquires the fingerprint information, a high-precision fingerprint image is acquired by enabling the fingerprint to form a capacitance array and then enabling the capacitance array to be combined with the sensing units to form a plurality of micro-capacitors.

Description

technical field [0001] The invention relates to the field of fingerprint detection, in particular to a fingerprint detection device. Background technique [0002] With the progress of society and the development of technology, in recent years, e-commerce services such as mobile banking, mobile wallet, and online shopping have been widely used on smart mobile devices. In contrast, the public has higher and higher requirements for the performance of integrated electronic components and network information security. Fingerprints are an effective means of personal identification due to their uniqueness and stability. At present, there are mainly two ways to obtain fingerprint images, one is to use ink and paper, and the other is to use equipment to capture images. The first method not only needs to spend a lot of time and energy, but the quality of the fingerprint images obtained Therefore, using devices to extract fingerprint images has been widely used in various fields. Eq...
