Embodiment 1

[0033] Such as figure 1 with figure 2 As shown, the fingerprint identification device of the embodiment of the present invention includes a cover plate 1, a fingerprint identification component 2 and an insulating protective layer 3.

[0034] figure 2 It is a partial cross-sectional schematic diagram of the fingerprint identification device. In order to illustrate the structure of the fingerprint identification device more clearly, the components in the figure are not directly connected, and it cannot be used to limit the connection relationship between the components of the fingerprint identification device of the present invention. . The instructions also apply to image 3 with Figure 4 .

[0035] The cover plate 1 has a first surface a, a second surface b corresponding to the first surface, and a side surface c connecting the first surface and the second surface. The cover plate 1 may be a transparent cover plate, such as tempered glass, tempered glass, polycarbonate, polyc...

Embodiment 2

[0064] Such as Figure 4 As shown, the fingerprint identification device includes: a fingerprint identification component 2'and a support 1'. The fingerprint identification component 2'includes a flexible circuit film 23' and a fingerprint detection element 21' and a fingerprint identification chip 22' formed on the flexible circuit film 23'.

[0065] The flexible circuit film 23' may be, for example, a polyimide film (PI film), and may be composed of two layers of polyimide resin (PI resin).

[0066] The fingerprint detection element 21' may be formed on the flexible circuit film 23'. At least one sensing element is included to sense the ridges and valleys of the user's finger, so as to identify the user's fingerprint. The fingerprint detection element 21' may have a one-dimensional structure or a two-dimensional structure, and the present invention is not limited thereto.

[0067] The fingerprint detection element 21' in the present invention may be a swipe sensor distributed in...

Abstract

The invention relates to a fingerprint identification device and an electronic device of the fingerprint identification device and a packaging method of the fingerprint identification device. The fingerprint identification device comprises a fingerprint identification assembly and an insulating protection layer formed on the fingerprint identification assembly in a covered mode. The insulating protection layer comprises a color layer formed on the fingerprint identification assembly and a protection surface layer formed on the color layer, wherein the interface between the color layer and the protection surface layer is provided with a diffuse reflection concave-convex shape, and the roughness of the interface ranges from 5 micrometers to 10 micrometers. By means of the fingerprint identification device, the glare problem of the insulating protection layer covering the fingerprint identification assembly is solved without affecting fingerprint identification; furthermore, better hand feeling can be obtained when a user touches or rubs the surface of the fingerprint identification device.

Description

Technical field [0001] The invention relates to the field of fingerprint identification, in particular to a fingerprint identification device and its electronic equipment and packaging method. Background technique [0002] With the widespread application of portable terminals in people's daily life, the functions of current portable terminals are becoming more and more powerful, and this diversified function is convenient for users. However, while providing more convenience to users, portable terminals carry too much private information. If such portable terminals are lost or stolen, this information is easily leaked out without relevant protection. Inconvenience to users. Therefore, it is very necessary to make some security settings on the portable terminal. [0003] The security function of a traditional portable terminal with a touch screen is nothing more than setting up software functions such as a keyboard lock on the portable terminal and realizing security by entering a ...
