Embodiment 2

[0095] The content in the second embodiment that is the same as that in the first embodiment will not be repeated here.

[0096] Figure 5 It is the fingerprint recognition module of the third embodiment of the present invention along the figure 1 The exploded schematic diagram of A-A' in the middle. Figure 5 The fingerprint recognition module 13 of the shown embodiment three and Figure 3A The difference of the fingerprint identification module 11 in the first embodiment shown is: the wrapping method between the fingerprint identification module 100 and the support 104 in the fingerprint identification module 13 , and the shape of the support 104 .

[0097] Such as Figure 5 As shown, the flexible circuit film 1000 in the fingerprint identification module 13 is shorter than the flexible circuit film 1000 in the fingerprint identification module 11, and the flexible circuit film 1000 in the fingerprint identification module 13 does not exceed the side surface of the lower ...

Embodiment 3

[0099] The content in the third embodiment is the same as that in the first embodiment, which will not be repeated here.

[0100] Figure 6 It is the fingerprint identification module of the fourth embodiment of the present invention along the figure 1 The exploded schematic diagram of A-A' in the middle. Figure 6 The fingerprint identification module 14 of the shown embodiment four and Figure 3A The difference of the fingerprint identification module 11 in the first embodiment shown is: the wrapping method between the fingerprint identification module 100 and the support 104 in the fingerprint identification module 14 , and the shape of the support 104 .

[0101] Such as Figure 6 As shown, the flexible circuit film 1000 in the fingerprint identification module 14 is shorter than the flexible circuit film 1000 in the fingerprint identification module 11, and the flexible circuit film 1000 in the fingerprint identification module 14 does not exceed the side surface of the...

Embodiment 4

[0103] The content in the fourth embodiment is the same as that in the first embodiment, which will not be repeated here.

[0104] The thickness of the protective layer 40 in the fingerprint identification device 1 of the embodiment of the present invention is, for example, 0.015 mm, the thickness of the color layer 30 is, for example, 0.01 mm, and the thickness of the adhesive between the color layer 30 and the fingerprint identification module 10 is, for example, 0.008 mm, the thickness of the flexible circuit film 1000 formed with the sensor 1002 and the control chip 1004 is, for example, 0.05 mm. Therefore, the fingerprint identification device 1 of the embodiment of the present invention can provide a very thin thickness, so as to meet the demand of terminal equipment for thinning and lightening its integrated components. The above-mentioned dimensions are for example only, and do not limit the present invention.

Description

technical field [0001] The invention relates to the field of biological identification, in particular to a fingerprint identification device and a terminal device including the same. Background technique [0002] In recent years, with the development of storage technology, terminal devices such as smart phones and tablet computers store a large amount of personal information and other important data, and its security has become more important. At present, passwords, graphics and other forms are often used to realize the password protection of its terminal equipment. [0003] However, for encryption methods such as passwords and graphics, users need to remember the set passwords and / or graphics; in addition, there is a danger of password disclosure in public places. In order to improve security, it is often necessary to increase the complexity of passwords and graphics, which undoubtedly further increases the difficulty of user memory, causing conflicts between security and ...
