Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a manufacturing method for a fingerprint detection device. The method comprises the following steps: enabling a fingerprint sensing chip, a light source module and a light-sensing detector to be installed on a conductive substrate, and to be electrically connected with the conductive substrate, wherein the fingerprint sensing chip is used for collecting a fingerprint image of a finger of a to-be-verified person; and enabling the conductive substrate to be electrically connected with a circuit board. The fingerprint sensing chip can enable the fingerprint image to be transmitted to a processor, and the light-sensing detector can enable an optical signal reflected by the finger to be transmitted to the processor. The processor enables the optical signal reflected by the finger to be converted into a pulse signal, and can determine whether the fingerprint sensing chip is started or not according to the pulse signal. The processor also can determine the identity of the to-be-verified person according to the fingerprint image. The above device can achieve the recognition of the fingerprint of a living body, and enables identity verification to be safer and more reliable.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a manufacturing method of a fingerprint detection device. Background technique [0002] The conventional fingerprint recognition device in the prior art only recognizes the fingerprint pattern to be tested, compares it with the fingerprint pattern recorded in the system, and if the judgment is consistent, it is determined that the fingerprint pattern has passed the verification. At present, a special imitation fingerprint film technology has appeared on the market. By copying the subject's fingerprint pattern, the fingerprint can be copied on a similar silica gel material. Because the copied fingerprint is the same as the subject's fingerprint, a conventional fingerprint identification device can also be obtained. The verification passed, which makes the security of identity verification originally intended to use the uniqueness of human fingerprints unguaranteed. Contents of the i...
